What is one of the benefits of a warm-up for muscles?

A warm-up is essential in preparing the muscles for more intense physical activity. The primary benefit associated with a warm-up is that the muscles relax more quickly, which enhances their elasticity and readiness for action. This process involves increasing blood flow to the muscles, which helps in raising their temperature. Warmer muscles can achieve better flexibility, allowing for greater range of motion and reducing the likelihood of strains or injuries.

As muscles become more pliable during a warm-up, they can transition from a resting state to an active state more efficiently, which is crucial for optimal performance during workouts or athletic events. This increased readiness also helps in coordinating movement and improves overall athletic performance, making the warm-up a vital part of any fitness routine.

The incorrect options highlight adverse outcomes that would not occur due to an effective warm-up. For instance, muscles do not become more rigid but rather more flexible; they should not tear more easily when warmed up; and instead of contracting less forcefully, warmed-up muscles can contract more powerfully and effectively.
