First, 525 squat at 185 is not a shitty squat at all, but it's far from actually strong. My sometime lifter Tom Feild can do that. How much can the kid pull? Press? This is relevant for a strength assessment too. Second, I don't know how long he's been in the sport. My guess is that he needs to be lifting at 94, and that he needs more food and less caffeine. There are several things that both you and I don't know.1. So, why isn't he even close to the top 85kg category competitors? and the bottom line, he's quite far from the top olympic level.
Not necessarily. Lots of very strong men have lacked explosivity, and lots of explosive athletes have failed to develop a lot of strength. In the first case, you don't have to be explosive to get strong. But in the second, getting strong is always harder than just being explosive, since you're born that way.2. You said that a good test for accelerating force production potential is the vertical jump. Does it say anything about strength potential? I mean, if someone is naturally more explosive, does it mean he has a better potential for squat, deadlift, press, bench press?
If you see an explosive fast "1RM", it's not a 1RM, because if you can move a weight fast you can move more weight slower. If a guy can't move more weight slower, he has not learned the skill of grinding through a slow, heavy rep. This is a SKILL that boys who are taught to dump their high-bar squats will not have a chance to learn.3. About 1RM bar speed. I watched a lot of 1RMs of diferrent lifters in the squat and the deadlift. As I could guess, there was diferrence in the bar speed between the diferrent lifters. Nothing new. But, if someones' squat 1RM moves up fast compared to someone else, does it mean he's more explosive, and would we expect his vertical jump to be better?
Why someone's bar goes up fast in the squat / deadlift / etc in maximal weights and someone else's goes up slow?
