MUSCLE PHYSIOLOGY

Detailed explanation-1: -Fast movements – box jumps, jump squats and kettle bell swings help target and train fast-twitch muscles for explosiveness. Heavier power exercises – exercise like power cleans and back squats focus on the power side of your type IIb fast-twitch muscle fibers.

Detailed explanation-2: -Fast-twitch fibers are good for rapid movements like jumping or sprinting that require fast muscle contractions of short duration. Unlike slow-twitch fibers, fast twitch-fibers rely on anaerobic respiration (glycolysis alone) to produce two molecules of ATP per molecule of glucose.
