Joint Sensation and Positioning in Exercise

Areeb Ahmed, [14/12/2022 17:22]

I think understanding the joint sensation component is more complicated. for example how the tibialis stretch on the poliquin step up may effect the knee. Yes it allows for more knee flexion but the same knee flexion on poliquin and patrick step ups feel vastly different. What if we looked at joint tension in a movement as a combination of the different tension "inputs" to a joint.

If we want less tension in a given joint then we decrease the joint angle of surrounding joints, if we want more then we increase the joint angle of surrounding joints.

This is a primitive idea, how would factoring in hip rotations further affect the tension in the knee?

So,the idea is joint sensation as a product of strength through length of the inputs (which can be manipulated through ranges of the systems of inputs and connections of those inputs to other joints).

Let me know if you see any mistakes in the reasoning. Will test this out later today.

I think it has a lot to do with positions… Leg press could grow legs but “without pressure on knees”. Hence, I’ve trained so many people who can’t play sports… But have leg pressed for years.

A deep squat would be more joint dominant BUT… When most people squat, even if they go deep, they try to avoid the positioning. So if your knees shoot back, etc., you could still make a squat less joint dominant. On a Slantboard you can’t though, it begins joint dominant because of the position.

So I think any rep range would still be joint dominant on a slantboard if there was no pain. Pain = avoidance of positioning. So someone lifting though pain is likely to become muscle dominant and not joint dominant, and be surprised by lack of jump results from “strength gain”/

This is why high reps works so well to get into and then train positions with less pain. But it doesn’t mean that heavy or low reps can’t be joint dominant. Just gets to be more advanced levels of form. A deep squat with chains, in my opinion the KING of exercises for muscle growth and strength, could still be very joint dominant if:

1. Executing pain-free

2. OWNING rather than running from joint positions

Charles Poliquin said the deep squat was the king of exercises. Thousands have said this. I would just add chains and ensure the form is amazing. Connor squat is joint dominant and he has a near 50” vertical jump. Stefan Holm had a joint dominant squat form, embraced the knees, ultra deep, most successful high jumper ever. Most joint-dominant squatter in high jump history. Kadour Ziani most joint-dominant exerciser in dunk history, greatest dunk longevity ever. It’s simple… You can literally build joints.
