What is the primary difference between the squat jump with stabilization exercise and the squat jump exercise?
a. The squat jump with stabilization exercise requires holding the landing position for 3 to 5 seconds, whereas the squat jump exercise uses a repeating tempo.
b. The squat jump with stabilization requires an external load to emphasize joint stability requirements, whereas the squat jump exercise is unloaded to maximize vertical takeoff velocity.
c. The squat jump with stabilization exercise requires a unilateral (one-legged) landing, whereas the squat jump exercise uses a bilateral (two-legged) landing.
d. The squat jump requires an external load to facilitate lower body strength, whereas the squat jump with stabilization is unloaded to maximize lower body power.
