A	Increase availability of Ca
B	Faster release of Acetylcholine
C	Increase muscle temperature for more efficient enzyme activity.
D	Increase of neuromuscular signaling
E	Activates anaerobic systems within the muscles.

Explanation:

Detailed explanation-1: -Warming up increases your heart rate and therefore your blood flow. This enables more oxygen to reach your muscles. A warm-up also activates and primes the connections between your nerve and muscles, which improves the efficiency of movement.

Detailed explanation-2: -When heat is applied to a sore area of the body, blood vessels widen and blood flow increases to transport excess lactic acid and other toxins away from tired muscles. These muscles are also made more elastic by the heat, and nerve endings are stimulated to block pain signals.

Detailed explanation-3: -Prepare your muscles and joints for activity by warming-up and stretching before you play. A warm-up routine increases blood-flow; raises the body’s temperature; and improves balance, flexibility and coordination, so you can play at your peak while avoiding injury.
