Other studies reported high school athletes are more likely to supplement their diet with protein than college athletes. Research shows that half of the athletes who take protein supplements are football players, although more protein supplementation is being seen in athletes other than football. There have not been studies conducted on human subjects of large doses of amino acid or protein supplements, and therefore no margin of safety is known. For most swimmers, amino acid or protein supplements are expensive, and unneeded supplements. Fluids and Hydration Training in a hot, humid environment can lead to dehydration.
Swimmers are vulnerable to dehydration, especially during the hot summer months.
Performance can suffer when a swimmer loses as little as 2 percent of body weight as sweat. To prevent dehydration, swimmers must drink plenty of fluids before, during and after a workout or competition. Thirst is not an accurate indicator of how much fluid a swimmer needs. One of the major concerns of this survey is the belief of young adolescent swimmers that thirst is an adequate measure of hydration status. To maintain hydration levels, swimmers need to keep a fluid bottle by the side of the pool when working out and drink as often as possible.
