Exercise and Weight Loss Reduces Kidney Disease and Death
Wednesday, October 14, 2009
Jolie Bookspan, M.Ed, PhD, FAWM
We recently found a cure for "irony deficiency disease." My near-7 foot tall husband and I were walking to a Vidocq forensic society meeting. A bake sale was set up in the building lobby - junk food, refined junk pastries, pies with artificial colorings. The sign stated "Bake Sale for Kidney Disease." I asked which items caused the most kidney disease. I was sure it was a staged joke for a commercial on nutrition awareness. The sellers were disappointed with me. Apparently, it was a real bake sale. "Bake Sale for Kidney Disease" is true, both for them and their kidneys.
Research reported in the Clinical Journal of the American Society Nephrology of pooled data from 13 studies showed found, in obese adults with kidney disease, losing weight through diet and exercise prevented additional decline in kidney function and reduced proteinuria, which is excess excretion of protein in the urine, a major characteristic of kidney damage.
Regular exercise of the recommended amount cuts risk of death in patients with chronic kidney disease by 56%, according to an analysis of National Health and Nutrition Examination Survey (NHANES) data. People who exercised, but less than recommended levels were still 42% less likely to die during follow-up than sedentary people.
1. Weight Loss Interventions in Chronic Kidney Disease: A Systematic Review and Meta-analysis. Sankar D et al. Clin. J. Am. Soc. Nephrol., September 17, 2009 as doi: 2. Physical Activity and Mortality in Chronic Kidney Disease (NHANES III). Beddhu S, et al. Clin J Am Soc Nephrol 2009; DOI: 10.2215/CJN.01970309. doi:10.2215/CJN.02250409.
Obesity is a major factor in kidney disease. A large percentage of the United States adults and children are overweight or obese, increasing their risk of kidney ailments, plus diabetes and high blood pressure, which in turn affect kidney function. More than 20 million Americans already have chronic kidney disease, with the number and severity growing.
Researchers of the Systematic Review and Meta-analysis stated,
"The health care costs that are associated with this increase are staggering. In obese adults, weight loss may offer real benefits in terms of the kidneys, in addition to the heart-related benefits of shedding excess pounds."

In the hot days of summer, common warnings involve avoiding the heat. What about the advantages of heat? Hot environments can improve your health in several ways.
Done right:
Exercising in the heat improves your fitness level and ability to exercise.
Exercising in the heat increases your tolerance to heat, making life more comfortable in the heat.
Exercising in the heat prevents the decreases in heat tolerance that otherwise occur with increased age, which can be unhealthy, even dangerous.
Exercising in the heat makes positive changes in your body that improve your fitness. You increase blood volume, improve cooling ability, make changes in sweating, increase the vasculature that helps circulation, cooling and exercising at the same time, increase specific chemical compounds in the body that improve health and ability to exercise.
When you exercise and increase body temperature, your body produces more of an interesting compound called heat shock protein. Heat shock proteins are families of proteins that do several things including preventing other proteins from damage by infection, ultraviolet light, starvation, heat, cold, and other harsh conditions. Heat shock proteins are thought to mobilize immune function against infections and diseases, even cancer.
Improved ability to tolerate heat without discomfort, called heat adaptation, occurs fairly quickly - with large improvements within the first week of exerting in the heat. Exercising in heat is more effective to produce heat acclimatization than heat exposure without exercise. Aerobic fitness is a major factor in heat tolerance.
It is a myth that you must avoid sweating to stay healthy. Exercising enough to sweat makes you more flexible, increases many chemical reactions in your body that are healthy. Sweat itself has compounds beneficial for your skin and body. Don't worry that you must exercise only indoors in air-conditioning in order to do healthful exercise. A protective environment does prevent initial discomfort, but reduces benefits and the ability to be comfortable in the heat.
This all does not mean to go out and cause yourself heat injury by overdoing without thinking. It is to gain the many benefits of exercising safely in the heat
I will cover more physical changes from exercise in the heat that improve health and exercise level in future articles.

Reader Robert Davis has been enthusiastically sending in success story after success story. He sent his first story of fixing a painful back injury from weightlifting - Fixed Injuries, Got Strong, With Functional Exercise.
Since getting the idea of using healthy daily movement instead of injurious movement during daily life and exercise, Robert stopped major causes of his injuries. He has rapidly been getting strong using fun functional exercise, and improving function. He has been taking ingenious photos using his camera phone. His stories and photos will be posted. He is sending them in fast and furiously. I enjoy hearing how he experiments with each thing, and sees and understands how they work so he can incorporate the concepts into daily movement, not just going thorough arbitrary motions and calling it exercise.
We are still having problems uploading photos and movies for you - since October. It has been a time-intensive and difficult process to get any photos at all uploaded for these posts. It has changed and delayed a few of the articles I wanted to write for you. When Healthline staff can help, they will. Robert generously made a page to store visuals so you can link and see them. Start with:
Watch how he uses a healthful squat for real life, not just 10 times in a gym.
Robert writes:
"Make a mess and pick up only one item at a time via a squat. If you need to clean the house only pick up one item at a time. The constant up/down motion of the squat etc should get the heart rate up for a good cardio workout. Why not kill two birds with one stone? Tired of the stationary bike? Do this for a half hour:)"
Good bending is natural built-in cardiovascular exercise, leg strength and stretch, Achilles tendon stretch, hip strengthener, warm-up for stretching, and back pain prevention, since it stop one major cause of back pain - bad bending (bent over at the waist or hip). Done properly, good bending strengthens knees and does not cause knee pain. The Related Posts below explain more.

The Shinobi no Mono, or the Ninja of old Japan, were renowned for their running speed and endurance.
Running drills called "ashi" (foot or feet) were an important part of Ninjutsu physical training. Try this basic Ninja ashi, or running drill:
Put a straw hat on your chest.
Run without holding the hat with your hands or other fastening.
Run so fast that the hat does not fall - this requires keeping a minimum speed for the duration of the ashi drill.
Where is the photo? He (or she - there were female Ninjas) must have run by so fast you didn't see. We are still working on the problem of photos not uploading. Healthline staffer Jerry has been helping to upload several photos for posts to come. Thankyou Jerry.

Here is Friday Fast Fitness - How to know what heart rate will give you a cardiovascular training effect.
Several formulas calculate exact heart ranges and "target heart rates." There are a variety of commercial (expensive) heart rate monitors. Arguments in sports medicine continue on which is the right formula and if heart rates in water or at elevation can be calculated the same way. These issues will be covered in posts to come. For now:
Your body is smart. Heart rate generally follows "perceived exertion." If you feel your running or other exercise pace is moderate, your heart rate is likely to be at a moderate training range. If it feels light, then heart rate will likely be too low to give much training effect.
Find something you enjoy enough to continue more than ten minutes at a time.
Keep a pace that you feel is moderate to hard, depending how you like it.
If your running or other exercise pace feels moderate, it is also moderate for your cardiovascular system. If it feels hard, your heart and body and mostly likely working hard for your current level If it feels light, then it is too light to give much training effect.

The new Indiana Jones movie came out this past weekend, the Kingdom of the Crystal Skull. It is set in 1957 with fun fitness and iconry of the era, for future blog posts. Today - the Rocket Sled.
In the early part of the movie, Indiana Jones and the Soviet Russians brawl through a US military testing base in Nevada. Jones and a Russian officer wind up on a rocket sled, which blasts them on a speed track into the desert.
Rocket sleds are one of several devices that create and test the effects of high acceleration on equipment and the people who use them. High acceleration forces occur when jets take off quickly, when launching a space flight, to eject from a hit (compromised) fighter jet, on roller coasters and spin and fall rides, when you fall from a height, and any time you change speed and/or direction quickly. Interesting changes occur in the body under acceleration. Acceleration is one of the areas of my study as a research physiologist and was my work for a time at two facilities testing air vehicle and human systems.
G-force is a measure of acceleration, not force, but the term g-force is also used for the reaction force that results from acceleration. More on meaning, spelling, and math of g and G in another post. Too much g-force can result in g-LOC (Loss of Consciousness), pronounced "jee-lock"in English, but just as meaningful when using the Cyrillic pronunciation of "loss." When piloting a multi-billion dollar property (the fighter jet) G-LOC is not a good thing for anyone. The pilot may convulse, called "doing an Elvis" because the flailing looks like playing an air guitar - a real air guitar. Then the pilot may "ding" (lose consciousness) and the vehicle may "descend below the level of the terrain" (crash) and "disperse energetically" (explode) and "value unfavorably" (be destroyed), and the crew and anyone they land on may "achieve a negative health status" (die).
So we test.
A rocket sled is a small platform. Rockets propel it on the ground on rails. It creates high onset g-forces for a time limited to the length of the track. When personnel or equipment riding it sit as in a car or plane, they experience acceleration pressing them from front to back (on an x-axis).
To measure the higher g-forces with short onset experienced in jet bail-out procedures, a vertical ejection tower can be used. A small seat is propelled quickly upward by a contained blast force under it (like lighting a bomb). If they are positioned to sit upright, the acceleration acts on them from head to foot, on their y-axis.
To experiment with varying accelerations over different amounts of time and onsets, one device used is a centrifuge. A long support arm swings around and around a center anchoring point -like swinging a ball on a string around your head. A container, often ball shaped, at the end of the support arm holds the equipment or personnel being tested. The ball can rotate to position the people inside at any angle to simulate the changing positioning of a cockpit during maneuvers, for example.
What happens to the people in these testing devices? Often they throw up all over my nice equipment. Some of my test subject pilots used to have contests who could eat the worst thing to redisplay on testing day. One ate plastic bugs just for the fun he was sure to cause - then he didn't throw up, no matter what we did to him. In vertical (y-axis) ejections, there is high impact and acceleration forces on the discs and spine. Back injury is a concern for ejection scenarios. Vibration, both during acceleration and non-acceleration situations, such as for helicopter and jack hammer operators seems to be a high contributor to back pain. It is not known if the various vibration devices sold as fitness devices are of the kind (vibration frequency or amplitude) that contribute to joint pain. G-LOC is another consideration. Why do we test it? To see how to prevent it, if we can screen for who is more likely to get it, if we can train those prone to it to be more resistant, and so on, in g-force tolerance improvement programs (g-TIP).
The set of photos at right is a well-known one of USAF Colonel John Paul Stapp, M.D., Ph.D., riding the rocket sled. He was a pioneer of acceleration study and is also known as the originator of the expression "Murphy's Law" for things that can go wrong. The effect on his face along the x-axis is not from his high speed, but the acceleration which is increasing in photos ii and iii, and decreasing in v and vi. Even though his speed is greatest in photo iv, speed is not increasing or decreasing much, so there is little effect.
More on the interesting effects of acceleration and environmental testing from roller coasters to jets to movies in posts to come.

Fast Fitness - Easy Handstand for Balance, Upper Body Strength -The Movie
Friday, May 09, 2008
Jolie Bookspan, M.Ed, PhD, FAWM
Here is Friday Fast Fitness - a quick, safer way to try a handstand. Standing on hands has many health and strength benefits and can be easily practiced in this way.
My student Dennis, Olympic medalist in wrestling, demonstrates in this short movie. Click the arrow to watch the movie:
Stand with your back about a foot in front of a wall, and crouch to put your hands on the floor (avoid slippery surface)
Put one foot high up on the wall, then lift the other foot up too
To get down, step one foot back down, then the other
To see step by step still photos and more explanation, click the post Fast Fitness - Easy Handstand where David from Belgium shows the handstand plus how to add a nice overhead hamstring stretch.
Keep breathing. Smile. Relax. Send in your own photos of trying this. Be safe and have fun.
Here is Fast Friday Fitness - if you have been afraid to try a handstand, here is a quick easy way to have success. You will strengthen your hands, wrist, arms, shoulders, upper body, and core, practice balance, and get blood circulating.
Crouch down near a wall (avoid slippery floor)
Put one foot high up on the wall
Lift up the other foot
To add a nice stretch on the hamstrings, lift one leg away from the wall into a wide split position in the air, as below.
If you have uncontrolled glaucoma or high blood pressure, ask your care providers first.

We are here working in Asia. Everywhere, we see schoolyards with kids playing sepak takraw. Modern sepak takraw is played on a court with three players on each side. Players don't use their hands to volley. They use feet, legs, shoulders, and head to keep the ball in the air, volleying back and forth. Main features of sepak takraw are acrobatic mid-air kicks to keep the ball in play, and the athleticism and speed of the players.
Sepak takraw has been played in Southeast Asia for hundreds of years. The word "sepak" is Malay for kick and "takraw" is the woven ball. In Thailand, the game is often simply called Takraw. In 1984, a Thai inventor revolutionized the sport with a synthetic takraw to replace the slower traditional rattan ball.
Takraw has roots in Malaysian, Chinese, and other national games. In Bangkok Thailand, there are wall paintings at the Wat Phra Kaew (Temple of the Emerald Buddha) of Hanuman, the Vanara (Monkey-like) Hindu god, playing takraw in a ring with his monkey troops. The game developed into teams competing across a court with a net, about the size of a badminton court. This modern-day version is a Southeast Asian specialty.
Thailand wins most of the gold medals at the Asian Games. Here is a motion clip of just 48 seconds of playing Takraw. Click the arrow to watch.
In Monday's post, Katharine, an Ironman Triathlete, told of having pulmonary edema of swimming twice this year and asked if warm up or fluids were involved. US Open Water Swimming also interviewed me about pulmonary edema. Here are some things they asked.
1. What is pulmonary edema and why should swimmers know or be concerned about it?
Edema means too much fluid accumulation. Fluid suddenly fills the lungs. The left side of the heart is not pumping properly. It can cause you to have to stop a race. It can sometimes cause serious illness and death.
2. Is it more likely to occur in cold water?
It seems to be more likely in cold water. It has occurred in surface swimmers and scuba divers in both cold and warm water. Cold is only one of the several proposed causes.
Causes or contributors seem to be things that increase cardiac preload and afterload, including immersion in water, cold water, heavy exercise, negative pressure breathing (like breathing with a snorkel, and swimming with the chest below the surface and even the slight elevation of the head to breathe in), and drinking too much water or other fluids before swimming. Don't drink lots of water before swimming.
3. What are the signs and symptoms?
Unusually shortness of breath (not just fatigue) and coughing bloody froth. No chest pain.
With a stethoscope you can hear rales, an abnormal rattling breathing sound. Chest x-rays show the classic pattern of pulmonary edema. When blood oxygen in the arteries is checked, arterial O2 may be lowered.
4. Do wet suits provide any measure of protection against PE?
Difficult to say since it has occurred in people with and without wet suits. I haven't seen charts where the numbers of each predisposing possibility, like protective garments and temperature, were compared.
5. Can medical personnel easily detect PE?
Pulmonary edema is not subtle. The person is usually gasping and spitting pink froth, and asking for help with a worried look.
A swimmer who develops shortness of breath and cough in a race may have something else like exercise induced asthma.
6. What is the first aid if PE is suspected?
Get them out of the water. Sit them up to elevate the head, if conscious. Give them 100% oxygen by mask, and get them to the emergency facility.
7. If PE is untreated and the athlete continues to the race/swim, what could happen?
Depends how serious. Symptoms can resolve on their own or they can get worse. I wish I knew the future for them, but it's like other injuries. There have been deaths. We wonder how many people who suddenly went under were not drowning but developed pulmonary edema. We have no way yet to tell. Drowning also produces pulmonary edema (after the fact). Repeat cases of pulmonary edema can occur in the same person.
Interestingly, the frothing pulmonary edema occurs in racehorses after hard races. They are blowing bloody nose froth all over, but veterinarians have reassured me that the horses are fine. Any readers who are veterinarians, please tell me more. If a person is frothing, get help.
"I am an Ironman Triathlete and have recently experienced symptoms of swimming induced pulmonary edema on two occasions this year and am trying to find as much information about this condition as possible. I have a background in swimming and have not experience this phenomena until recently. In both instances, my breathing became labored and fluid built up in my lungs during the early stages of a competitive triathlon swim.
"The most recent instance of what I suspect was 'SIPE' (Swimming Induced Pulmonary Edema) was on July 22nd at Ironman USA in Lake Placid. After the swim portion of the event, I had to be taken to the hospital as I was unable to breathe and was coughing up a 'pink frothy foam.' I felt normal within 24 hours and have still been able to continue to train as normal –initial ECG and Echo tests of my heart are normal, as well as a lung scan and x-rays of my lungs, throat and sinuses.
"The problem has only occurred in 2 out of 4 triathlon’s I have been in this year – and both instances occurred at approx. the 750m mark of an open water swim.
"It doesn't seem to be a common ailment so I’m trying to gather as much information on SIPE as possible from anyone who has studied it. I'm primarily trying to find out how to prevent it from happening. I am fine in training in the same 'open' cold water as I race it, so why is it happening on race day... Perhaps not enough of a swim 'warm-up' and an immediate elevation in HR... that along with added fluids in the days leading up to a long distance event such as an Ironman."
Warming up does not seem to be related to developing pulmonary edema. Why pulmonary edema can happen with swimming, what fluids have to do with it, and what to do, follow on Wednesday - click Swimming and Pulmonary Edema Part II .
Grunting in the gym made recent news. A member was forcibly removed from a gym when others complained. The article told of factions arguing who was right if grunting and other loud vocalizations when exerting for exercise were helpful or needless annoyance.
Exercise is supposed to be healthy and build discipline of mind and body. Antagonism and disputes are not healthy for mind or body. Moreover, both sides have missed the point.
Breathing out, either quickly or slowly in coordination with effort can help. It can be done silently - by exhaling without vocalizing. You can have both, the exhale and the peace. This quiet but forceful exhalation practice is used in many high exertion fields from martial arts to warfare to meditation.
Fighting ninjas were legendary for both focused effort and silent tactics. No sense making a war cry until it was needed for its better purpose - to increase tendency to submission by the other party on the receiving end of the cry. In other words, to be scary.
For exercise, focused exhalation can increase acceleration at specific points of the move to increase power. For heavy moves, it can help lessen increases of pressure in the chest cavity and blood vessels, depending how it is done. Sometimes, people put so much pressure into the exhalation that they increase internal pressure instead of prevent problems. Done either quickly or slowly, it can be used to strengthen the move by including expiratory muscles. Often in martial arts and yoga classes, we (teachers) use noisy breathing just to remind students to breathe at all. It is a cue until they remember to breathe on their own (quietly) instead of holding their breath.
In the war dances and drumming in many countries, in martial arts, and in meditation arts, a concentrated exhalation coordinated with effort is variously called kiah, kiai, hihap, battle cry, and other terms. Each school is certain that their own different translation and beliefs about these terms is the "right one." The exhalation can be vocalized in a short yell, a loud breath, or silent. In group efforts, from martial arts to hauling sheets on tall ships, to chain gangs, to exercise classes, it helps unify mood or keep cadence. Done without coordinating effort, it is called yelling, and sometimes it is just vocalizing in corny ways.
More about breathing, the kiai exhalation, and exercise for any sport are in the book Healthy Martial Arts.

Here is Friday Fast Fitness - Train speed and eye-hand coordination while having fun.
Have you seen martial arts movies where the master catches a fly with his chopsticks? The true master doesn't restrain or harm the lives of others. In the spirit of healthful exercise, World Vegetarian month and higher spirit, try this instead:
Tear a sheet of paper to different size pieces
Throw in the air
Catch as many pieces as you can as they flutter downward.
Want more? Use only one hand to catch. Then switch.
You can play this with children too. Get more exercise and prevent pain by using healthy bending to pick pieces up and start again.
"Vegetarians have the best diet. They have the lowest rates of coronary disease of any group in the country. [T]hey have a fraction of our heart attack rate and they have only 40 percent of our cancer rate." —William Castelli, M.D., Director, Framingham Heart Study, the longest-running epidemiological study in medical history
From my work in sports medicine, I will add to Dr. Castelli's work that I see fairly consistent reduction in joint pain and other pain syndromes when patients stop known "inflammatory foods" including meat and dairy.
October 1 is World Vegetarian Day (www.WorldVegetarianDay.org). The month of October is Vegetarian Awareness Month. The purpose is for a happier, more aware and respectful, and healthier society.
Hurting animals is unhealthy for all involved. In the spirit of healthy body and mind, this post gives four ideas:
Build your own health and benefit your exercise: food and recipes for better exercise training (regardless of your sport), and preventing disease and pain syndromes. Get the book Healthy Martial Arts
Free vegetarian starter kit, free newsletter, with materials in Spanish, to avoid cruelty to yourself, animals, and the Earth, one meal at a time - TryVeg.com
Reduce global warming: GoVeg.org reports on work published in NewScientist.com - It's Better to Green Your Diet Than Your Car (17 Dec. 2005). "You could exchange your "regular" car for a hybrid Toyota Prius and, by doing so, prevent about 1 ton of carbon dioxide from entering the atmosphere each year, but according to the University of Chicago, being vegan is more effective in the fight against global warming; a vegan prevents approximately 1.5 fewer tons of carbon dioxide from entering the atmosphere each year than a meat-eater does. The math is simple: You could spend more than $20,000 on a Prius and still emit 50 percent more carbon dioxide than you would if you just gave up eating meat and other animal products."
Feel encouraged. Being vegetarian or making occasional vegetarian meals does not have to involve any strange or expensive foods from specialty stores. You do not need any special pots or food processing equipment. It is a myth that vitamin supplements are necessary. Grocery bills can also be also far less expensive when you don't purchase meat (and don't substitute other expensive food that you do not need).
More Good Stuff:
I will post easy-to-make healthful (real) food for athletes and exercisers, during October vegetarian month, and for Vegan month in November.

Parcours is pronounced par-core. It is a French word meaning "course" or trail. A parcours is a path with obstacles at varied intervals. You navigate using your body and brain, similar to steeplechase. Some parcours are formally designed municipal parks. Some are impromptu collections of trees, walls, buildings, windows, and rocks. On a rainy day you can make your own in your house.
In ancient times, a course might involve days of travel. Today, several cities around the world have public courses used by people of all abilities and ages. Modern fitness programs use it, with names like freerunning and various brand names, but the idea is not new.
Stations may be a log to walk across, rings to swing on, various height and shape objects to stretch on and around, a place to see how far or high you can jump, something to balance on, a ladder or wall to climb over or under.
To get to the next station, you can walk, run, bike, skate, or whatever you can do. Parcours length varies from a block to miles. Some people make a day of it with picnics and rests between stations. Others go make a quick lunch run over part or all of the course.
In the early 1980s I was the first person to put exercise programs aboard cruise ships. Until then, cruises were associated only with deck chairs and food. I was told exercise would not catch on. I ran exercise, health education, and stretch classes, and led the scuba and snorkel trips. I also led a parcours, taking about an hour, all over the ship, from deck to deck, stem to stern, over and under tables, chairs, hatches, and railings, and through the cha-cha lessons. We ran, we walked, we balanced, we cha-cha'd, we tip-toed very fast to get away, we laughed.
Parcours uses the body in natural ways to build strength, spirit, and balance. It can be healthier, better training, and more fun than doing artificial repetitions of an isolated exercise.
More to come on keeping parcours safe for joints, and preventing injuries.

The week before I left to teach at the Wilderness conference, I taught my University yoga class entirely on an exercise ball. I will post about functional movement on a ball in weeks to come.
We don't use three of the most ineffective things you can do on a ball - crunches, sitting on the ball (for almost anything), and arching the lower back over the ball. These seem to be three of the more common things done on the ball in fitness classes, but they are not fit or effective.
Another myth is that an exercise ball will magically make you sit straight. You can sit with as faulty positioning as on any other surface.
Most of my students brought in an owned or borrowed exercise ball. I brought in three more for students without access. Some of the students pin-balled cheerfully through the narrow doorway with a large inflated exercise ball. One came in on the subway holding hers. I managed a comic, calorie-burning commute with three on a bicycle. A few students brought theirs uninflated. Wow, such an idea.
They asked me if I had a pump.
I told them, "Yes, your lungs, blow it up."
They sat politely waiting for the other students who brought a pump to finish with theirs.
I chided them that people talk all about yoga and breathing but here was opportunity in the tangible. They sat politely waiting for the pump. I demonstrated - "fffooooooooou."
I told them that when I was small, I was transfixed when my father, a Russian ice swimmer, blew up a beach ball in one breath. I decided then and there that I wanted to do that. I experimented with bags. I'd inflate to all my capacity and compare the bag to my little chest. I later practiced this in my swimming career until I was measured by scientists who came one day to test our whole team. My lung volume (not counting residual that you cannot breathe out) came in close to 6 liters. They called me a sports car. I didn't know what that was and hoped they were not flunking me. Who knows how much was from my 35 to 40 mile a week swimming training, or inherited, or just lung size relative to height. Still, a "big engine" can be trained and added to the mix. Click the label "breathing" under this post for entries about training breathing and exercise capacity.
My students took a chance on believing me that breathing and yoga and health had something to do with real life, and took a big breath to the ball. Bigger, bigger, full. Then quick hands to cap it off. They laughed. Laughing is good for breathing too. Then we started class.
Take a nice full breath in right now. Let your lower abdomen come outward. Exhale normally.
Breathe when you cook, clean, and do daily life. Don't hold your breath or gasp.
Blow up balloons, pool floats, air cushions, enormous inflatable beach toys. Don't overbreathe and get dizzy.
Exercise until you have to breathe a lot. Don't let yourself get so out of shape that it ever becomes unhealthy to try fun exercise.

I am still getting caught up with work from the sports medicine meeting I attended in late May.
An interesting study was presented at the pulmonary and respiratory physiology session - "Effects of a High-Fat Meal on Pulmonary Function in Healthy Subjects." It is known that high fat meals negatively affect people with asthma and other pulmonary problems. It is also known that a high-fat diet increases internal inflammation, which is associated with higher risk of heart disease, diabetes, rheumatoid arthritis (possibly other forms of arthritis such as osteoarthritis), and several other chronic illnesses. What about effects on your lungs and breathing?
The study looked at the effect of a high-fat meal on airway inflammation and pulmonary function. The researchers tested subjects for total cholesterol and triglycerides, then fed them a high fat meal. Subjects were tested after the meal for cholesterol and triglycerides, various pulmonary functions, markers of airway inflammation (exhaled nitric oxide), and C-reactive protein, which is a marker of systemic inflammation. The researchers found that the high fat meal increased total cholesterol, triglycerides, and exhaled nitric oxide. They concluded that the results suggest that high-fat meals may contribute to inflammatory diseases of the airway and lung (in addition to other health consequences).
Just as smoking or taking amphetamines are not healthy, but help weight loss, popular weight loss diets "work" but have health drawbacks. Check your meals to see if you eat high fat, whether for a diet, or just from unhealthful eating habits.
A diet may help weight loss, but be unhealthy. An exercise may work a muscle but be bad for your joints. A medicine may fix a disease but harm the patient. You don't have to choose. Many fun healthy ways to exercise and control weight that don't harm the body are given throughout this Fitness Fixer blog.

Respiratory Muscle Training for Better Health and Exercise
Monday, July 02, 2007
Jolie Bookspan, M.Ed, PhD, FAWM
At the American College of Sports Medicine conference last month, I attended an entire session on effects of training respiratory muscle function. Back when I was in school, we learned that the ability to breathe harder, better, faster, could not be trained with exercise or other modality, that it was fixed from person to person, like eye color, except that it got worse with aging, and that it didn't matter much, since ventilation did not do much to limit exercise potential anyway.
Even though the lungs don't have any muscles of their own, it didn't seem right to me, as the diaphragm and muscles that move the rib cage to voluntarily breath in and out are muscles like any other. What if there are people whose respiratory muscles are not trained to work hard enough and add to the metabolic cost of exercise, increasing fatigue and so, limit exercise? It is also true that many people are not in good enough shape to use more oxygen, so breathe most of the oxygen back out with each breath, even when exercising strenuously. What about someone in great athletic shape who could use that oxygen. Why couldn't they be trained to move more air faster if they needed some?
Exercising the muscles that you use to breath in (inspiratory muscle training) is known to improve the endurance of the respiratory muscles in people with spinal cord injury and cystic fibrosis, and is shown to improve exercise capacity in patients with heart failure. What about for people without these conditions or for athletes?
Combat swimmers have long used various breathing training to get in shape for swims and other strenuous work. The diving medicine conference I attended two weeks ago had several studies that showed interesting and promising results with breathing training.
Respiratory muscle training in the above studies did not involve popping corks from your lips, as in the photo. To improve your breathing capacity and do training at home without respiratory training devices, see the Fitness Fixer post Do Breathing Exercises Work? and the book Healthy Martial Arts.

It is estimated that every 30 seconds someone in the world has their foot amputated because of a diabetic foot ulcer. Reduced blood supply to the feet and lower legs in people with diabetes delays wound healing and increases infection and chance of gangrene. Foot infection worsens the situation of inadequate blood supply by increasing the area's need for oxygen but decreasing blood supply. Poor blood supply further decreases ability to fight infection. Diabetic ulcers treated with antibiotics can become colonized with drug-resistant bugs.
I am at the annual meeting of the Undersea and Hyperbaric Medical Society (UHMS). Several interesting studies are being presented on diabetic wound healing. Enhancement of healing in selected problem wounds is one of the 13 approved indications for use of hyperbaric oxygen therapy as defined by the Hyperbaric Oxygen Therapy Committee. Hyperbaric treatments are done by putting the entire person in a small room or chamber and increasing the pressure inside so that the person breathes oxygen at higher pressure than what you are breathing now. The post Does Hyperbaric Oxygen Help Exercise Ability? explains more of how it works.
One of the studies presented here looked at 50 patients with severe diabetic foot ulcers. Half were treated with hyperbaric oxygen therapy (age and gender matched with the half who did not). Diabetic patients treated with hyperbaric oxygen had 56% chance of healing and 16% chance of amputation. Diabetic patients not receiving hyperbaric oxygen therapy had a 32% chance of healing and a 32% chance of amputation. Supplying oxygen to compromised areas, such as diabetic wounds, is important to restoring health. Hyperbaric oxygen is established to help that.
From the President's Competition came another study on hyperbaric oxygen therapy and stem cell mobilization in people with diabetes. This study was by researchers at the University of Pennsylvania's Institute for Environmental Medicine, where I did nine years of my research in diving medicine. Hyperbaric oxygen is already known to mobilize bone marrow stem cells in animals, healthy humans, and in patients with a history of radiation exposure. This study looked at diabetic patients with refractory foot ulcers or radiation necrosis who were receiving hyperbaric oxygen treatments. The study was small and results varied more than in previous trials. However, the researchers reported that overall, hyperbaric oxygen therapy increased circulating CD34+ stem cells three-fold in the patients with diabetics, and was shown to play a role in wound healing. Three patients of twelve in the study group did not increase stem cells. The researchers said that the reason for no increase should be investigated.
In the exhibit hall of the hyperbaric conference, various companies display their fun oximetry units. There are several kinds of oximeters. The most common ones painlessly assess oxygen levels through the skin. Oximetry is used to assess oxygen available to the injured and surrounding tissue, and to tell how well hyperbaric oxygen treatments are working to improve oxygenation and new blood vessel growth. I like to try them all on, on different parts of my body. I experiment with different exercises to see the different effects on oxygenating different areas. Movement makes rapid, effective increases in oxygen levels.
In the past, people with diabetes were cautioned not to exercise because it was felt that they would injure themselves. Now it's known that exercise is an important part of preventing injuries from diabetes, and preventing or curbing diabetes itself. Regular exercise:
Helps your body burn more sugar.
Increases the number of insulin receptors on your cells and increases the sensitivity of your body to insulin.
Helps your body grow new blood vessels and improve circulation.
Improves oxygen levels to areas to help them heal.
Reduces high blood fat levels (cholesterol and triglycerides) which leads to early aging of blood vessels.
Increases blood flow to the feet, which helps prevent diabetic foot problems.
Keep moving for many aspects of preventing disease, secondary effects from disease, and to improve your health.
I am attending the annual meeting of the American College of Sports Medicine (ACSM). There are many hundreds of studies, seminars, clinics, workshops, lectures of all sorts, running concurrently. It is like drinking candy from a fire hose.
Dashing from one lecture to another in the enormous conference center trying to learn as much as possible from simultaneous sessions is exercise in itself.
Some of the "studies" predictably show glowing results. Studies funded or conducted by candy bar manufacturers show athletic gains from eating their candy bar. A study funded by the US Poultry Association concluded that dietary cholesterol may have a modest role in muscle mass and strength increases (and an "uncertain role on cardiovascular risk factors.") Studies from sugar water manufacturers, who are also major sponsors of this sports medicine conference, show high results in athletic events drinking their product. There is no doubt that hydration and blood sugar are enhanced from refined sugar products to complete athletic events with good results. Commenting professionally, I am not sold on these products for long-term health. Moreover, you can get the same results in most cases with healthier food. The post Is Your Health Food Unhealthful? gives some healthy food choice ideas. Click the label "nutrition" accompanying that post for all Fitness Fixer posts that give ideas for healthier sports nutrition.
One nice little study from University of Pittsburgh researchers showed that overweight adults who achieved higher levels of physical activity during a weight loss program also reported "adoption of eating behaviors recommended to improve weight loss." They also found that, "Failure to sustain physical activity reflects the failure to sustain recommended eating behaviors." The bottom line is still, "Stay active and eat right."
Another nice study from the Nutritional Interventions sessions found that, "Individuals at risk for developing cardiovascular disease (CVD) can reduce risk factors through diet and exercise before resorting to drug treatment," that, 'Ingesting vegetable versus animal protein has also been shown to have beneficial effects on various risk factors" and that "Participation in a 12 week resistance exercise training program significantly increased strength and decreased CVD risk factors in overweight, hypercholesterolemic men with no added benefit of protein supplementation." The bottom line is still, "Stay active and eat right."
Neolithic groups (stone age) worshiped the mother. Ancient Germans worshipped the virgin Hertha holding her child. Scandinavians worshipped virgin Disa holding her child. In ancient Egypt it was Isis with infant Osiris. In India, Devaki had Krishna (also by virgin birth). In Asia, Cybele and Deoius. Chinese holy mother Shing Moo held her child in arms. Christian missionaries to Tibet, China, and Japan found that holy mothers depicted with splendid light around their head and holding a divine child had been worshiped long before they got there.
In Rome, the goddess was Demeter, meaning Earth Mother, wearing wreathes of braided corn in her hair. In ancient Greece, Demeter was called Ceres, the great mother with baby at breast. From her name "Ceres," we get the word "cereal" (grains), "which made man different from wild animals."
In the spring in ancient Greece, celebrations were held in honor of Rhea, the Mother of the Gods. Christian Europe celebrated the spring festival of "Mother Church" who (they believed) would protect them from harm. During the 1600's, England celebrated "Mothering Sunday" on the 4th Sunday of Lent, honoring the mothers of England. All cultures worshiped the divine, the Mother, who gives life and food, compassion and love.
So. How to celebrate this Sunday on Mother's Day? I'm in favor of some goddess worship, probably involving some rocks and food and chocolates and compassion and love. Not so original, but time tested and universal:
Visit Mom (or a Mom) and give her a massage (if she wants one). Neck, hands, feet, back. Good for circulation for giver and receiver. Touch can be healthy. Ask her stories.
Make her (and you) something healthy to eat. For light teas, try cinnamon, cloves, grated orange peel, or ginger in hot water.
For a cold treat without unhealthy junk food, mash a frozen banana with crushed raw walnuts or flax seeds. Use a food grinder or get free exercise by mashing them yourself in a bowl. It will taste like creamy ice cream. Flax seeds and walnuts have been found to be effective to help bone health as vegetarian sources of omega-3 (n-3) fatty acids. Raw walnuts (as part of a general low fat and cholesterol diet) have also been found to have a beneficial effect to decrease cardiovascular disease risk, among other benefits. This treat has fiber and is non dairy, both associated with lower breast cancer risk.
Goddess worship often is helped with chocolate. The primary chemical in chocolate is theobromine. "Theo-" means God and "broma" comes from a word meaning food. The theobromine in chocolate was named for "food of the gods." Theobromine is an antioxidant, weak diuretic, stimulant, and mood booster, opens breathing airways, and relieves coughing. Dark chocolate has more theobromine than lighter chocolate, with flavonoids and phenolics, plant substances that are good for the heart. People who get a kind of vascular headache called migraine do better not to eat chocolate. For others, get plain cocoa, unsweetened, not junked up with sugar. Add the unsweetened cocoa to the frozen mashed banana and walnuts for a healthy sweet wonderful treat that tastes better than you would expect. For exotic flavor and more health benefit, add fresh grated ginger root.
Sit outside in the air and sun to have your tea and frozen banana. Warnings on the dangers of overtanning are important for preventing skin cancer for people who work outdoors, who over-tan for cosmetic purposes, and a few other populations. Another group to consider is those spending too little time outdoors. Sunlight exposure and the Vitamin D it makes your skin produce, is increasingly documented as crucial to bone density, healthy immune function, positive mood, sound sleep at night, relief of symptoms of rheumatoid arthritis, fibromyalgia, MS, Parkinsons, polycystic ovary, diabetes, and other health issues. A nice massage and tea and chocolate outside in the sunlight could be made into a wonderful Mother's Day. Nice excuse to buy a hat.
Make Mom (or a Mom) some homemade healthy skin lotion. Commercial products have preservatives, dyes, and chemicals. Try combinations of grape seed oil, tea tree oil (very small amount), vitamins C and E, ginger, honey, tea, fresh aloe, and fragrances from oils, fruit, flowers like lavender, or leaves like mint. (Don't wear citrus oils like lime out in the sun.)
Help out at a woman and child shelter. Or help at a men's shelter to help the guys get back on their feet to help their own families.
Celebrate Mother Earth - go out and pick up litter. It's good exercise. Bend right.
Make a trip to look around a home improvement center to see about some do it yourself solar projects, even if only to replace a few lights.
On April 1st, I covered some fun fitness myths and how to change myth into healthier exercise. Today continues with more fun ways to get more exercise and reduce injury at the same time:
Heart Health
Myth - Anger has no health effects. Instead, turn contempt and anger for others to healthy dialog with: Healthier Heart.
Understanding How "Sticking Out in Back" Isn't Neutral Spine:
Then try Using Abdominal Muscles is Not Tightening or Pressing Navel to Spine to visualize how you simply tuck enough to make the belt line level when standing, not tilted. A small inward curve in the lower back remains when you shift to neutral spine, but not large enough to cause degenerative pinching on the facet joints, the joints of the lower spine.
Myth - Pressing navel inwards to tighten abs is the way to strengthen your abs or fix your posture. Fact - tightening will not move your spine out of unhealthy position and it impedes normal fluid motion: Using Abdominal Muscles is Not Tightening or Pressing Navel to Spine.
Exercise Injuries
Myth - Exercise injuries are usually overuse and aging. Fact - Simple misuse is easily fixed: Why So Many Aerobics Injuries? and What is "Fitness as a Lifestyle?" A recent injury survey by US military revealed that 62% of American injuries in Iraq are occurring in the gym. Welcome to the Fitness Fixer tells more. Some top docs say the military press should be avoided. I think it is a functional exercise and can be done in ways without upper body injury: Safer Overhead Military Press.
Myth - surgery is necessary to avoid later problems. Fact - Studies have now found that is it not true that you necessarily risk future consequences if you do not have surgery. Surgery itself can be a source of later trouble: Fix Disc Pain Without Surgery and Studies Say Back Surgery Not Needed.
Myth - Vertebral discs just go bad without warning, from small provocations like a sneeze or reaching or from aging, so it doesn't matter what you do. The good news is that discs are not soft "jelly donuts" as often described. They are tough like truck tires. It takes years of the same, specific, problem to break them down and move them out of place. See the mechanism: Disc Pain - Not a Mystery, Easy to Fix
Myth - knocks to the head are funny and harmless. In reality, long-term damage may be common and serious. This has far reaching implication for law enforcement, domestic violence, full contact sports, and extreme entertainment: Rocky IV and Head Injury.
Sitting and Back Pain:
It made headlines when researchers seemed to say that sitting up straight was wrong. Here is what they really meant: Don't Fall for "Don't Sit Up Straight."
Scorn, anger, name-calling. Not good for the heart. The best warrior wins without hurting others or himself.
The Thais call it "jai yen" - cool heart. The secret is to not make anger a negative force. They keep kindness in their voice. Jai yen is central to Thai social and business interaction. It illustrates the mind and body of the experienced warrior. Jai yen is part of Muay Thai boxing training. In Thai martial arts, respecting teachers and elders is foremost. Every fight begins with the Ram Muay, a spirit dance to show respect and thanks to parents, and ask blessings from the Kruu Muay Thai - the teachers. In Japan it is "fudoshin" - unchanging heart. A person with fudoshin is more stable and light-hearted when things happen that they don't agree with.
How do you get good at being heart-healthy? Practice it like exercise. Unlikable things happen every day, so we all have the good luck to get much chance to practice. It's healthy exercise. In the novel Shogun, James Clavell, wrote:
"To think bad thoughts is really the easiest thing in the world. If you leave your mind to itself it will spiral down into ever increasing unhappiness. To think good thoughts, however, requires effort. This is one of the things that discipline - training is about."
Discipline is the mental exercise of self-control to direct your behaviors. With discipline you brush your teeth everyday, and do exercise, and refrain from bad habits, and breathe and smile when someone is rude. The other person may continue injuring their own health with negative behavior, but you won't sadden yourself and injure your body with the unhealthy chemicals generated that can hurt your health and heart. If your kindness and understanding calms and comforts the other person, that is twice healthy. Breathe. Get outside in the sunshine every day. Be happy.
Keeping Thai Massage Healthy Part III - Should You Do "The Blood Stop?"
Wednesday, February 07, 2007
Jolie Bookspan, M.Ed, PhD, FAWM
The previous three posts have started telling about Thai Massage. Thai massage is done lying comfortably on a soft mat on the ground. No table is needed. It is done clothed, except for bare feet. Most places in Thailand have Thai massage going on in the stores, on street corners, in the internet cafes, at restaurants, on the beaches, and other organized or impromptu sites. Southern Thai Massage style concentrates more on pressure points. Northern style adds wonderful stretches.
Thai massage is generally helpful, but there are a few moves to avoid. One is the "blood–stop." There is much discussion about this maneuver, both for and against. It helps to understand what is really going on to be able to decide.
The practitioner may press their palms, knees, elbows, forearms, shins, or feet over the big blood vessels that bring blood to your legs, or over the arteries that conduct blood to your arms. They press enough to slow or stop blood from flowing to your legs or arms as long as 30 seconds, a minute, sometimes more, depending on the style and school where they learned. When they release the pressure that was restricting the blood, blood flows back down the limbs in a warm rush that some people enjoy. Thai massage practitioners are taught to never do the blood stop on anyone with high blood pressure, varicose veins, heart or circulatory problems, or pregnancy. But it turns out that it is also not healthy for others.
It is often taught in massage schools that the blood stop helps unplug clogged arteries. The theory is that if there were deposits that block the artery, the rush of blood returning would "unplug" the blockage and carry it away, like cleaning a clogged plumbing pipe. This does not work for several reasons. First, the rise in blood pressure from stopping (or slowing) blood flow is small and not enough to dislodge anything when flow is released. You increase your own blood pressure more from ordinary walking and exercise. Next, even if it could dislodge anything, anything that dislodges from your big blood vessels can travel to a smaller place to become a foreign clog there - in the same way that damage occurs from a brain clot or heart attack or phlebitis.
Another idea taught is that slowing arterial blood helps draw away "stagnant" venous blood from the limbs. This is not how circulation works, even if it sounds good. Even though the blood stop will not help, you can easily do exercise that improves circulation both arterial and venous. When you exercise, the contracting muscles squeeze your limb vessels and push blood that pools in the limbs. The post Collapsing Astronaut Gives Healthy Reminder explains more on blood pooling and what exercise does for circulation.
Another of the theories of the blood stop sometimes taught in massage schools is that it helps counter the phenomenon of "legs falling asleep" during long sitting or meditation. The belief is that "legs falling asleep" is caused by lack of blood flow, and the blood stop will strengthen or increase circulation to alleviate that problem in the future. A little knowledge of physiology shows why neither is true. Compressing arteries to slow or stop blood does not cause any increase in the number or size of blood vessels, or ability to pump blood, any more than having clogged arteries improves circulation. The blood stop does not reroute the blood or encourage the body to find new pathways which give circulatory benefit. Exercise will increase all these good things, but doing the blood stop does not, even if we wish it does, or were taught that it does. Next, when a limb "falls asleep" it is not lack of blood flow, but nerve compression. There is no reduction in blood flow when you get the tingling and the "pins and needles" feeling of a limb falling asleep. The tingling is called neuropraxia, which just means a temporary interruption of sending nerve signals resulting in pins and needles feeling. During the blood stop maneuver, there is no pins and needles feeling, and when you stand up after your legs "fall asleep" there is no warm rush of blood as after the blood stop. They are two different things.
The next problem is an interesting phenomenon. When you stop blood to an area, it is not healthy for the area. Cells starve. Nerve cells are the most sensitive to lack of oxygen. Thai massage practitioners are sometimes taught that it is not stopping blood but "opening the wind" to release stagnant blood or energy. Still, no matter what you call it, lack of blood flow is not great for the area. Then the interesting paradox occurs. When blood flow, called perfusion, is restored to any body area that was deprived, oxygen flows back into the area. That would sound helpful, but the oxygen itself causes a second injury. It floods the area with a kind of oxygen that is not healthy along with other harmful products. It causes a serious injury called a reperfusion injury. This same kind of injury occurs with heart attack or in a limb that may have been crushed or caught under something, depriving it of blood. First, areas of the heart or the limb that are shut off from oxygen begin to die. When blood flow is restored, oxygen flows back into the area and with it, and a cascade of oxygen damage.
You may have heard of anti-oxidant compounds in foods. Many processes can damage your cells by oxidizing them. Oxidation is a natural process and needed for many things. But too much is not healthy. Free radicals were thought to be involved in oxidative damage. Your body naturally produces anti-oxidants to balance this and other oxidative stress from other sources. Many people take anti-oxidant vitamins hoping that more is better, which is not always the case, and only works to sell products. Separately, anti-oxidant vitamins and your own body's defenses can't do enough to protect you against a sudden reperfusion injury. Much interesting work in high-pressure oxygen science deals with trying to understand and avoid the paradox of the reperfusion injury.
There is more, but in short, none of this means that Thai massage is not good, just that it is best to avoid the blood stop move. It is easy to avoid the pitfalls and hype of massage, and use Thai massage and other kinds of massage for the benefits.

We have just gotten home to Thailand after over 40 hours of flights. It would have taken longer to walk here, so we are happy. We unfolded husband Paul, just under seven feet tall, from the seat. During the next month and a half we will travel on 14-hour overnight trains and ferries to places we need to be. Paul will practice good bending almost everywhere as he tries to fit under low Asian doorways, roofs, and bus ceilings, bow lower than the old people, and stand and sit with his head lower than the head of the monks, as is respectful.
Most people sit a great deal even without long travel. Sitting puts higher pressure on the back and spine than standing. Long sitting pressures the back far more. Sitting also means keeping the hip bent forward at the crease of the leg. The muscles in front of the hip shorten and tighten. When most people exercise, their exercise is usually more bending forward. The result for most people is that the hip stays bent almost all the time. Much tightness results that prevents normal hip function, and reinforces the same tight, bent positioning that is so hard on the spine.
Long airline flights sometimes provide a video or printed message encouraging in-seat exercise and stretching. Often the advice is forward bending. That is the last thing most people needs. Instead, try the following:
Stretch your back and shoulders backward, not forward. Pull your chin in while pushing your upper back backward against the seat back. Stretch arms overhead. Breathe.
Lean the back of your head and upper back against the seat, press your feet on the floor, and raise your hips, trying to straighten your hip at the "crease" of the leg. Don't bend your neck forward; leep it straight. You will feel your thigh and hip muscles working to do this.
Turn in your seat to each side to brace your elbow against the seat back for the pectoral stretch, shown in Fixing Upper Back and Neck Pain.
Stretch the back of your legs by straightening your knees and pulling your toes back using your shin muscles.
Increase leg circulation by pressing both feet against each other, then cross your ankles and pull both feet outward against each other, then cross your ankles the other way and repeat. Try it again with both legs out in fron, as in the stretch above.
Get out of your seat as often as you can. Restore length to the front of your hip with the hip-tilt quadriceps stretch shown in Instantly Better Hip and Quadriceps Stretch.
With one foot far in front of you and the other in back (lunge position) tip your hip under you to stretch the front of your hip. As soon as you tilt your hip under, you will feel the difference. While holding the hip tilt, bend both knees to dip straight down almost to the floor, then up. Do many, then switch legs and do many more.
It is easy and unobtrusive to do wall stretches while waiting for the rest room: Rest your head, heels, hip, and upper back against the wall, described in the post Breasts Causing Upper Back Pain is a Myth. Bring both arms overhead, hands touching the wall. Lean your body far to one side then the other. Keep both hands touching the wall. When Paul does this one, his head is often either against the ceiling or he can't stand up fully at all, depending on the type of aircraft. He bends knees and grasps each elbow overhead, keeping elbows touching the wall behind him. For other people short enough to fit standing up, just stand straight.
Then stand a step away from the wall and stretch arms overhead and back to touch the wall, fingers pointing downward. Straighten elbows as much as comfortable and keep the stretch coming from your upper back, not lower back.
On Friday, a day after the shuttle Atlantis returned after 12 days at reduced gravity, one of the astronauts collapsed twice during the welcome home ceremony. The reasons are the same as what happens here on Earth.
When you stand and sit on Earth, some of your blood pools in the veins of your legs because of the pull of gravity. In space, the pull of gravity is weak so blood does not pool. Blood floats upward. Astronauts and mission control scientists refer to the upward shift of blood during space flight in a technical manner. They call it the "Fat-Face-Chicken-Legs-Effect."
Upon return to the gravity of Earth, blood is again pulled downward. More pooling than usual occurs and not enough blood may be able to get to the brain. It is not uncommon for astronauts to feel weak and dizzy.
You may notice the same venous pooling on land in several situations: Sometimes when you stand suddenly, the rush of pooling in legs briefly lowers blood supply and blood pressure to your head. You may feel light headed. When this happens you just need to bend over and get your head down. Lowering your head allows gravity to restore blood, relieving dizziness. Extreme pooling has caused occasional cases of fainting when standing suddenly, when standing long periods at attention, and when climbing out of the water, especially hot water in spas and hot tubs. Pooling has been fatal to beached whales.
In space, the human body quickly gets badly out of shape without the pull of gravity. Muscles do not have to work to pull bones and quickly weaken. Bones do not have the muscular pull they need to stay dense and lose much calcium and bone mineral. Astronauts lose bone in space no matter how much calcium they eat. The cardiovascular system does not have to work as much to pump blood. This is why astronauts must exercise so much during missions.
Here on Earth you need regular activity that contracts leg and other muscles to squeeze the vessels to keep blood moving. After sitting for long periods at work and on a plane, your feet may swell with pooling fluids. Contracting your leg muscles while sitting, and by getting up and moving around pumps blood upward, reducing pooling and your risk of clots. For daily life, you need activity to keep muscles and bones from weakening. Even if you are sick it is crucial to get up and out of bed every day to stop the huge health losses that occur. Being sedentary is so devastating to health that bed rest is used as a model in scientific studies for loss of many health benchmarks in the microgravity of space. Stand to exercise, get outside, and enjoy some fun activity every day. Smile - another way to exercise against gravity.
Gravity and activity are important for health. Thank the astronaut, Heidemarie Stefanyshyn-Piper, for reminding us.
