Aerobic sports involve submaximal effort over long periods of time. The aerobic nature of these activities results in a steady creation of ATP energy in working muscles, allowing athletes to continue working for as long as there is sufficient fuel and for as long as the body does not become overheated (hydration state is important). Athletes who can rely more efficiently on fats and less on carbohydrate (glycogen) typically have better endurance because they have more fat fuel than glycogen fuel, which has limited stores. Because fats require a high amount of oxygen for efficient metabolism, the endurance athlete with the best oxygen system (e.g., most oxidative enzymes, best ability to carry oxygen to working cells) has the best endurance. What follows is a sample of endurance sports and their special nutrition considerations.
