What is a benefit of proper warm-up and dynamic stretching before exercise?

A key benefit of proper warm-up and dynamic stretching before engaging in exercise is the increase in muscle temperature. Warming up helps to elevate the temperature of the muscles, which leads to improved elasticity and efficiency in muscle contractions. When muscles are warmer, they become more pliable, allowing for greater range of motion and reduced risk of injury during more intense physical activity.

Increased muscle temperature also facilitates better blood flow to the muscles, enhancing the delivery of oxygen and nutrients while aiding in the removal of metabolic waste products. This physiological aspect supports performance improvements, as the muscles can operate more effectively and energetically.

While other options may suggest various benefits, they do not accurately correlate with the primary advantages associated with dynamic stretching and warming up. For example, improved cognitive ability does not directly stem from these activities, and decreased flexibility contradicts the intention of dynamic stretching, which aims to maintain or improve flexibility. Overall, the enhanced muscle temperature is a definitive and scientifically supported outcome of a proper warm-up routine.
