What is a benefit of a proper warm-up and dynamic stretch prior to exercise?

1. Increased risk of injury

2. Decreased performance output

3. Increased muscle temperature

4. Reduced flexibility

The correct answer is: Increased muscle temperature

A proper warm-up and dynamic stretching routine before exercise serves several important purposes, one of the primary benefits being increased muscle temperature. When muscles are warmed up, they become more pliable and flexible, which facilitates better movement and reduces the likelihood of muscle strains or tears during physical activity. As the body temperature rises, it causes various physiological changes: increased blood flow to the muscles, enhanced enzymatic activity, and better nerve conduction velocity. All these changes contribute to a more effective performance and a lower risk of injury. Dynamic stretching specifically helps prepare the muscles, joints, and connective tissues for the movements involved in the upcoming workout or sport. It engages the muscles in a way that mimics the activity to come, which allows for optimal coordination and readiness. Promoting muscle temperature not only enhances physical performance but also aids in psychological readiness by activating the neuromuscular system and improving focus. Therefore, the benefit of increased muscle temperature is a critical aspect of a proper warm-up routine.
