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.

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

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.
