THIS PARAGRAPH COMES FROM AN EBOOK DISCUSSING DEVELOPMENT OF VERTICAL JUMP FOR BASKETBALL. ANYONE CARE TO OFFER EXPERT COMMENT ON THE HIGHLIGHTED STATEMENT PLEASE.
Muscular Contributions To Each Style
Itís also worth mentioning that the muscular contributions to a uni-lateral (single leg)
takeoff vs a bi-lateral (2 legged) take off are different. Both of them rely on the muscles
of the glutes, hamstrings, quadriceps, and calves, yet the contribution that each muscle
group provides changes depending on the style of jump. The unilateral jump relies much
more on the glutes, hamstrings, and calves with the quadriceps providing a lesser role.
The bilateral jump relies on the quadriceps musculature for up to 50% or more of the
power output. The glutes and hamstrings are inherently fast twitch muscles and tend to
be more efficient then the quadriceps when contracting at very high speeds such as those
that occur in a unilateral take off. The quadriceps tend to be more efficient when
contracting a little slower.
