A. increase the myoglobin content B. tone the muscles and stabilize the joints for the workout C. convert glycogen to glucose D. enhance the availability of calcium and the efficiency of enzyme systems

Answer 1

Answer: B. tone the muscles and stabilize the joints for the workout

Step-by-step explanation:

Warm up exercise helps to activate the muscles via stretch reflex when the muscles are lengthened. It helps to loosen the muscles and joints and thus helps to prevent any kind of injuries.

There are basically three steps of warm up. namely, loosening of joints , stretching of muscles, pumping of the heart, and practising of the actual movements of the exercise. All these ultimately increase the muscle's capacity to work and also stabilizes the joints to prevent any kind of injury.
