Tim Henriquez (ofzo, ken die vent niet), heeft daar wel een interessant stukje over;
"The truth is that your joints are very sensitive to their internal stability, we have proprioceptors inside our body that sense and detect things for us. Your body can detect when a joint is stable or not. When it is not stable, the body will inhibit (shut down) some of the muscle force that can act on that joint. You can see this very easily by performing a pull-up and then use one less finger each time to grasp the bar. Most people when they get down to 2-3 fingers are no longer able to do a pull-up. The weight didn’t change (your bodyweight), your lats didn’t change, but the stability did change and now you can’t perform the exercise.
What is the most flexible joint in the body? The shoulder. Because it is so flexible it isn’t very stable, and it relies on muscle and surrounding tissues to derive some of its stability. As you gain weight by adding muscle you will increase that stability. Honestly
even adding fat will serve as a wrap which add stability to the shoulder girdle and thus increase the potential force that can cross it. I am not a proponent of them but this is one reason why bench shirts work so well, they surround the shoulder joint and greatly add to the stability which is one reason why they add so dramatically (about 30-50% if you can believe that) to the lift."
Hoe de wetenschap hier over denkt weet ik niet, dus het blijft gissen, maar ik ben van mening dat zelfs fat gains je bench sterker maken.
Sorry voor de logvervuiling
