Separating out deceleration as a separate training component is a fantasy. You have to accelerate to decelerate. It is essential a closed loop as illustrated by the performance paradigm. Certainly deceleration is where most injuries and performance errors occur but to try to isolate it just creates another step that will just confuse the body.
Keep it simple, design progressions that incorporate all elements of the performance paradigm and repeat the movements frequently preferably as part of warm-up daily. Use as many joints as possible to produce force and use as many joints as possible to reduce force. Honor and respect the wisdom of the body.Use as many joints as possible to produce force & use as many as possible to reduce it. @coachgambetta Click To Tweet
