Hello. This question is incomplete. The full question is:
"Which of the following is not a shared similarity between warm-up and cool-down routines? A. Restore muscles to their resting length. B. Help prevent injury. C. Stretches performed can be the same. D. Consist of a modified version of the exercise performed, such as a slow jog before or after a strenuous run."
A. Restore muscles to their resting length.
Explanation:
Restoring the muscles to the resting length is not a feature shared between heating and cooling. However, even with some shared factors, it is important for every athlete to warm up and cool down to avoid injury.
Usually, the athlete starts the warm-up session with exercises that contain rhythmic movements and active stretches of small intensity, increasing the pace as the body warms up. In the case of specific sports, the athlete performs low-intensity activities related to the sport to be practiced. Raising muscle temperature increases your flexibility, allowing your muscles to contract faster than cold muscles. Blood flow must increase substantially to protect muscles from injury during exercise.
At the end of the exercise session, cooling is as necessary as warming up, allowing the body to eliminate lactic acid from the muscles, a metabolic product that accumulates in the muscles after exercise. The gradual reduction of efforts (cooling) also helps to prevent dizziness. When exercise is suddenly stopped, blood accumulates in the lower limbs and does not reach the brain in sufficient quantity, causing dizziness. Cooling is also important to help normalize blood pressure and gradually relax the body structures involved in exercise. The characteristics of cooling are similar to those of warming up, with total body exercises prioritized and lasting an average of five to 10 minutes.
