Other than age, training history, and injury history, what screening tool is most beneficial in assessing whether a client is ready for plyometric training?

A

Movement assessments

37
Q

What are ground reaction forces?

A

Forces imparted on the body when it contacts the ground after jumping

Q

What is the correct order of the phases of plyometric exercise?

A

Eccentric loading, amortization, concentric unloading

44
Q

Why are plyometrics best performed on grass playing fields, basketball courts, or tartan tracks?
