Athletes' abilities to meet these demands affect how well they perform. Food, rest, drink, and other factors can affect an athletes' success. This study explores the effect of dehydration on how well a basketball player's body and mind performs. Dehydration is when the amount of water in the body is less than normal. This study has 2 trials. One trial looks at the affect of dehydration on playing basketball. This trial causes dehydration by having the player workout in a hot room until the desired amount of his body's water is lost through sweating. The amount of water-loss is tracked by weighing the body before and during the workout. The other trial looks at the effect of a sports drink on how well the player performs. The amount of water in the body stays normal for this trial. All trials use basketball drills to create a mock basketball game to test how well the player's body performs. A blood sample is taken to make sure that the player is able to be in the study. For each trial, the player swallows a special pill that measures the warmth inside the body
