What can be a consequence of dehydration during exercise?

Dehydration during exercise can significantly impact an individual's performance. When the body loses fluids and electrolytes, it leads to decreased blood volume, which in turn can affect the cardiovascular system's ability to deliver oxygen and nutrients to muscles. This can result in fatigue, reduced stamina, and overall diminished physical performance. The body also struggles to thermoregulate effectively, which can increase the perception of effort and lead to overheating, further impairing one's ability to perform at a high level. As a result, maintaining proper hydration is essential for optimal exercise performance and endurance.

The other options suggest outcomes that are typically not associated with dehydration. For example, improved endurance and enhanced recovery would be unlikely as both typically require adequate hydration levels to support metabolic functions and muscle repair. Similarly, a lower risk of injury is not a consequence of dehydration; in fact, dehydration could potentially increase the risk of cramps and injury due to muscle fatigue and reduced coordination.
