I havenāt looked for nor seen anything about that. I remember seeing some stuff in the past about starting your lift at maximum tension yielding better results though, so that may or may not feed into what youāre asking.
Maximum tension in this instance (and I might be using the wrong terms here) meaning like bench press - people tend to bounce the weight off their chest a bit to get some momentum, or cut the downward phase short a bit. The most effective way is to lower it completely, pause, then press. Basically like starting from a dead stop on your chest every rep.
Same for every exercise - pull-up, dip, squat, curls, etc. Rather than getting into a rhythm where motion never stops, treat every rep like itās the first rep from a standstill.
Kettlebell swings and the like are probably exceptions to this, as their focus is on constant motion.
Iāve also seen many studies saying after a certain point in the lift, the resistance decreases significantly due to momentum. So the first 2/3 of a bench press motion is where 90% of the work is done, and the last 1/3 doesnāt do much for you. Donāt hold me to specific numbers by any means. The entire range of motion is very important, but the final however much doesnāt get much resistance. Thatās where those isometric machines PTs used to love work their magic - they had a constant resistance throughout the entire ROM. They were wildly popular and desired in the 80s-mid 90s, but the machines were huge, only did one motion, and were absurdly expensive, so most PT clinics only had one or two different machines at most.
Hope this somewhat answers your question. Wait, what was your question exactly?
