What impact does dehydration have on athletic performance?

Dehydration has a significant negative impact on athletic performance, particularly in reducing both strength and endurance. When an athlete becomes dehydrated, the body's ability to regulate temperature diminishes, leading to an increased heart rate and a drop in blood volume. This results in decreased oxygen delivery to muscles and can impair physical performance.

Specifically, dehydration can lead to muscle cramps, fatigue, and decreased coordination. This not only affects endurance during long-duration activities but can also diminish strength during high-intensity efforts. Studies have shown that even a small percentage of body weight lost due to dehydration can adversely affect performance levels. Therefore, maintaining hydration is crucial for optimal athletic functioning and performance.
