The JSW Level
You brought up "hang time"...I'm talking about the velocity/biomechanics of entering into the LEAP. They're different concepts/stages...and account for the difference in two 40" jumpers being successful in their QUICKNESS to block shots or otherwise. Similar to fast TWITCH & slow TWITCH muscle fibers in sprinting & LD running.
Again:
Factors that affect initial velocity of a JUMP:
The more powerful your calves, quads, hamstrings, and core, the more force you will exert on the ground and more speed you will leave the ground with (Pavg=∆W/∆t). The heavier you are, the more force is required to accelerate your body to your initial velocity (F=ma).
Two (2) good ISU comparisons would be GEORGE PILLOW and STEVE HART. Both were similar great leapers, but PILLOW was the quicker of the two because of his superb lower body musculature.
Glad you cleared that up, BS~
