Which of the following is a purpose of dynamic warm-ups?

Dynamic warm-ups are specifically designed to prepare the body for physical activity by gradually increasing the heart rate and enhancing circulation to the muscles. This type of warm-up involves active movements that mimic the exercises or sports activities that will follow, effectively priming the muscles, joints, and nervous system for performance. The primary goal is to enhance overall body readiness, which helps in preventing injuries and improving performance.

In contrast to this, relaxing the body before an exercise session, increasing muscle soreness, or reducing mobility does not align with the objectives of dynamic warm-ups. While promoting relaxation may be beneficial in other contexts, such as cool-downs or recovery practices, it is not a primary purpose during the warm-up stage. Similarly, muscle soreness is typically an undesired effect of exercise and not something that should be promoted through a warm-up routine. Reduced mobility is counterproductive as well, since dynamic warm-ups aim to improve range of motion rather than decrease it.
