So it seems like if I do SVJ starting from the bottom ATG pause then jump up, I jump just as high or even HIGHER than the normal SVJ of going down then up.
WTF does that mean?
could mean a few things:
1. You're engaging the primary muscle groups (especially your glutes) for jumping better when you use the static squat jump form.
2. You're not engaging your glutes with a normal SVJ
3. You're rate of force development is "slow", so a static squat jump allows you to produce more force over a longer time span, including the tension built up from getting into position.
4. Your SVJ and static squat jump form are very different.
6. Your ability to generate tension during the eccentric (negative) phase of the SVJ is lacking.
7. You're not driving yourself down explosively during the negative phase of the SVJ.
8. You're simply more strength dominant right now (and in general), relying primarily on force created by muscle, with not much contribution from elastic/reactive components.
9. does it seem like that, or do you actually jump higher from a static hold than with a countermovement? perception is not always reality. have you measured?
so, nothing wrong with a higher static squat jump than SVJ, if SVJ is your goal. For basketball however, you'd want your SVJ to improve closer to your squat jump, especially at less depth - since you rarely hit depth during a game of basketball. Having a high squat jump usually also indicates your RVJ will use a similar form.. again, good if goal is jumping/dunking, worse (but not as worse as slow SVJ) if you also have goals of using that vert in games etc.
peace!
