What role does proper hydration play in physical performance?

It slows down metabolism.
It maintains body temperature and performance.
It reduces the need for calories.
It enhances fat storage.

The correct answer is: It maintains body temperature and performance.

Proper hydration is crucial for maintaining optimal physical performance. It plays a significant role in regulating body temperature, which is vital during exercise, especially in warm conditions. When the body is well-hydrated, it can efficiently manage heat production generated by muscle activity, helping to prevent overheating. Additionally, adequate hydration supports cardiovascular function by ensuring efficient blood circulation, which is necessary for delivering oxygen and nutrients to working muscles. This enhances endurance and overall physical performance, allowing individuals to train harder and recover more effectively. Therefore, maintaining proper hydration directly contributes to both temperature regulation and improved athletic performance.
