had a really painful corn on the bottom of my left foot. decided to use an electric filer to file it down. still hurts.

Heard this from raptor a while ago, want to confirm. 1 foot jumping places less stress on the knees?

can still dunk 1 handed off the dribble off 1 foot. definitely think that planting LR gives carryover to 1 foot off left.

makes sense, and also anecdotally my experience. LR plant is really a left-foot plant, i.e. your left left absorbs more of the force than your right. i'm naturally LR and a right-foot SL jumper, but my left-foot SL plant caught way up to my right-foot plant over the years.

oh nice. yea for me my right leg is still stronger, but my left leg is catching up. interestingly, even though my right leg has been stronger for all these years ive always been able to jump higher off my left. guessing its more of a coordination thing though

Gonna take the alternative stance here and say that LR DLRVJ carries over to R-SLRVJ more. Main reason being the long GCT of the left foot in the LR DL plant makes it have more of a strength role while the quick concentric rebound with the right leg (where it's probably generating most of the concentric force of the jump) is more power oriented and more closely resembles what happens in a SL jump.

Might be different for different people, but I don't think there's should be a whole lot of eccentric force absorption in a SL jump, that force should be transferred to the jump, not absorbed by the leg. If I'm wrong and that eccentric absorption is important in the SL jump, maybe doing DL jumps has a similar effect to drop jumps where the leg learns to absorb high forces fast, but it's more specific than drop jumps because the forces being absorbed are horizontal rather than vertical.

Feel like before when I was a RL only planter it didn't help much with my 1 foot off left though. in fact it actually made it more quad dominant

I understand but the theory of it doesn't make sense to me is all I'm saying. Do you think there are other factors at play?

When you have a dedicated jumping session, do you mix SL and DL jumps in a single session? In my opinion, most of the time you shouldn't. When you rehearse similar skills within a short time period, the brain can mix up the mechanics. In some cases this can be helpful but most of the time you don't properly develop either jump.

The rule I read about was practice similar motions 6 hours apart so the mechanics don't get mixed up.

i see. i just felt like making the left leg stronger was just gonna help with the 1 foot jump.

and i see. yea most, of the time i didn't, and still don't.


bottom line though, is that practicing the 1 foot jump is the best thing to do to increase it. just trying to find out now if 1 foot jumps have less stress on the knee.

 I would say SL jump is dealing with much higher forces (faster approach, only 1 leg to absorb force) which have to be transferred in a shorter time period (shorter GCT), but the quad is in a strong position to produce a lot of force and protect the knee ligaments from absorbing that force.

If your quads are weak or if you're quad dominant and you rely on excessive knee bend (collapse at the knee) to produce power during the SL plant, that's going to put a lot of stress on the ACL.

In my case I was quad-dominant and tried to SL jump by bending at the knee. I've had a lot of SL jump sessions and only when it was high-volume, high frequency and high intensity I had some knee pain after sessions. Always went away in a short time period though.

Man I really wish this forum was still alive and we had people like raptor, adarq, t0ddday, merrick and lance so we could actually have different perspectives on theory rather than me trying to piece this stuff together.

I see. well i've never had any problems with ACL, just the quad tendon. hopefully can eventually transition to being a full 1 foot jumper again.

still can touch 10'2 off 1 step, LR plant. gonna continue with both trap bar and straight bar deadlifts in the future. am not looking to bulk anymore at all though, eating is just too much of a chore. just maintaining my weight is already somewhat of a chore already, so may potentially lose weight.

LR jump still very hip dominant. i can jump off LR with high top shoes without a problem.

gonna continue strengthening posterior chain i guess. gonna still be mainly a LR planter, but still wanna be able to get off of 1 foot.
