Definition

Exercise is any activity requiring physical exertion done for the sake of health. Activities range from walking and yoga to lifting weights and martial arts.

Origins

Regular exercise as a way of promoting health can be traced back at least 5,000 years to India, where yoga originated. In China, exercises involving martial arts, such as t'ai chi, qigong, and kung fu, developed possibly 2,500 years ago. The ancient Greeks also had exercise programs 2,500 years ago, which led to the first Olympic games in 776 B.C. Other exercise routines have been in use throughout Asia for hundreds of years.

Only within the last 100 years have the scientific and medical communities documented the benefits that even light but regular exercise has on physical and mental health.

The earliest forms of exercise stressed activities that involved stretching and light muscle resistance. Next came martial arts that promoted self-defense. In nearly all forms of Asian exercise routines, some type of meditation was a major component because the ancients believed physical and mental health went together. The ancient Greek and Roman civilizations advocated vigorous physical activity since exercise was associated with military training. The Greeks also believed that a healthy body would promote a healthy mind.

"Physical culture" was popular in the nineteenth and early twentieth centuries. Medical journals showed exercise machines in the 1800s in Europe and North America. Although weight training became popular with a small number of people in the 1940s, it was not until the 1960s that regular exercise programs began to flourish throughout the United States. Gymnasiums, once used mainly by male weight lifters and boxers as training facilities, now are common throughout the United States. Today's gyms and health clubs offer a wide range of exercise activities for men and women that can fit every lifestyle, age group, and exertion level.

Benefits

The medical community recognizes that regular exercise, along with a proper diet, is one of the two most important factors in maintaining good physical and mental health, and in preventing and managing many diseases. Most certified physical trainers advocate at least 20 minutes of exercise at least three times a week. But for people who have a sedentary lifestyle, even walking for 10 minutes a day has health benefits. One study of 13,000 people followed for more than eight years showed that people who walk 30 minutes a day have a significantly reduced risk of premature death than people who did not exercise regularly.

Walking and other cardiovascular exercises can reduce the risk of heart disease, some cancers, hypertension (high blood pressure), arthritis, osteoporosis, stroke, and depression. A study by the Centers for Disease Control and Prevention (CDC) reported in 2001 that running just once a month could help keep bones strong. In addition to physical benefits, a 2001 study showed that exercising just 10 minutes a day can improve mental outlook.

A study released in 2003 reported that exercise combined with behavioral therapy may even help manage the symptoms experienced by Gulf War veterans. Specifically, exercise helped improve symptoms related to fatigue, distress, cognitive problems, and mental health functioning. In the same year, the American Heart Association released a statement saying that exercise was beneficial even for patients awaiting heart transplants. Another study showed that women who participated in strenuous physical activity over a number of years could reduce their risk of breast cancer. Finally, research showed that men and women age 40 to 50 who exercised moderately for 60 to 90 minutes a day were less likely to catch a cold than those who sat around.

Description

Exercise comes in many forms, but there are three basic types: resistance, aerobics, and stretching. Yoga and martial arts are basically muscle stretching routines, walking and running are primarily aerobic, and weight lifting is mainly resistance. However, exercises such as swimming are considered crossover activities since they build muscle and provide a good aerobic, or cardiovascular, workout. Certified physical trainers usually advocate a combination program that involves stretching, aerobics, and at least some resistance activity for 30-60 minutes a day three times a week.
