In squatting for jumping improvement, IN MY OPINION, the amortization phase, the point in the movement where the bar goes from downward motion to upward, is the single most important part of the lift. I have seen and strongly believe that the athletes who can turn the lift around the fastest will always have the best carryover to jumping. It is more about how quickly you can get to top speed at that particular point in the lift, than the overall speed attained during the movement.
Interesting point and I think adarq has said this before in reference to REA squatting and jump squatting. I'm pretty sure I suck at this part of the movement. Any cues/tips on improving it?
yup, that's why I prescribe REA squatting, to aid in the transition.. that's why I also always say to focus on the transition as much as possible, during squatting.
the most important thing definitely is mental, always cueing yourself and making sure to really transition as explosively as possible, in all squat reps.. so lance's nail cue is great etc.
other than that, REA squats/depth jumps/depth drops & jump squats help.
I've found REA squats to be most effective in terms of carry over to the squat.. depth jumps/depth drops definitely can have carry over also, even more so if you're using intense box heights, that also improves the transition during ballistic movements, greater force produced during the "coupling phase", that iso between eccentric and concentric.
