Which condition is a potential result of not hydrating properly before practice?

Dizziness is a common and concerning result of inadequate hydration before practice. When the body doesn't receive enough fluids, it can lead to a drop in blood volume, which impairs circulation and decreases blood flow to the brain. This can cause dizziness, lightheadedness, or even fainting. Proper hydration is crucial for maintaining the body’s fluid balance, supporting cardiovascular function, and ensuring that vital organs receive sufficient blood supply during physical activity.

In contrast, other conditions like cold sweats and muscle tightness can arise from various other factors, including heat stress or intense exercise, but they are not as directly linked to hydration levels as dizziness is. Excessive energy would not be a result of dehydration; in fact, it is more likely that dehydration would lead to fatigue and a decrease in overall performance. Thus, maintaining adequate hydration is essential for preventing discomforts like dizziness and ensuring optimal physical performance during practice.
