When a 5'10" powerlifter who squats 8oolbs can't touch the rim of a basketball hoop but a 5'10" guy who squats 350lbs can that's a demonstration of power. When a guy who benches 225lbs can punch harder than a guy who benches 450lbs that's power. Power is how quickly you can release your strength. Most Olympic lifters while having incredible strength have amazing power. Most can sprint a good time and do amazing vertical leaps. You won't find many powerlifters who can say that.
for the record, none of this really makes sense. just going by physics definitions (work = force*distance; power = work/time) you're just talking apples and oranges. power has nothing to do with how fast you move, it has to do with what you did for that time. an 800lb squat is, without question, a feat of greater power than dunking a basketball. period.
more than that, jumping and punching don't even use the same muscle movements as squatting and benching. a punch is a unilateral movement that uses a lot of hips, jumping uses a lot of ankle strength and a very narrow dip. unless you're punching someone with both arms at the same time while lying down or someone jumps by dropping ass to ankles first you might as well compare deadlifting with climbing a tree. they're not even related.
bodybuilders are much "athletes" as runway models, but this jimjam about strength and power and how a dude who can jump or throw a punch is more "powerful" is just nonsense.
