D)  last a minimum of 8 weeks and maximize movement velocity 
A)  last a minimum of 4 weeks 
B)  last a minimum of 8 weeks 
C)  minimize landing forces 
D)  last a minimum of 8 weeks and maximize movement velocity D

Question 2

Discuss the need to perform plyometric drills differently when the focus is on injury prevention as opposed to performance enhancement.

Accepted Answer

Performing plyometric exercises with the goal of injury prevention requires specific instructions focusing on reducing landing forces in order to minimize risk potential. Landing from a jump is a common mechanism of injury. Teaching proper landing mechanics could be effective in reducing injury risk. For injury prevention, teach athletes to land with greater hip, knee, and ankle flexion.
