What might be a consequence of dehydration during physical exercise?

Choosing reduced performance as the consequence of dehydration during physical exercise is accurate because hydration plays a crucial role in maintaining physical capabilities. Dehydration can lead to a decrease in blood volume, which means that less oxygen is delivered to the muscles. This loss of fluid can result in fatigue, increased perceived exertion, and a decline in coordination and focus.

When the body is dehydrated, thermoregulation is also impaired, leading to an increased risk of overheating. As a result, athletes may experience poorer endurance, a reduced ability to sustain high-intensity efforts, and an overall drop in performance levels. Hydration is fundamental for optimal physical function, and even mild dehydration can negatively impact athletic output and increase the risk of injury.
