What benefit does an effective warm-up provide for physical performance?

An effective warm-up plays a crucial role in enhancing physical performance by facilitating nerve transmission and muscle metabolism. During a warm-up, the body undergoes several physiological changes that prepare it for more intense activity.

One key aspect is the increase in temperature within the muscles, which enhances their elasticity and function. Warmer muscles contract and relax more efficiently, contributing to improved strength and coordination. Additionally, the warm-up stimulates the nervous system, enhancing communication between the brain and muscles, which leads to better reaction times and overall performance during the workout.

Moreover, warm-ups increase blood flow to the muscles, thereby improving the delivery of oxygen and nutrients necessary for energy production. This optimization of muscle metabolism allows for more effective use of energy sources during exercise, leading to improved endurance and a reduced risk of injury. Overall, option C accurately captures the essential benefits of an effective warm-up in terms of its influence on both nerve and muscle functions.
