I think swim 'power' can be measured, using stretch cords. One of
these that barely allows you to reach the other end of the pool. (there are other more expensive options like weighted pulley systems used by college teams) . I think it could also be set up in a way to actually measure the force produced with the right scale attached to the anchor point.
As you near the limit of the cord's ability to stretch, you are also going really slow so forward drag is not the limiter, it is the power you can put directly into moving forward. I end up taking about twice as many strokes for the resisted 25 compared to normal.
I think it would be super interesting to see how well a bunch of triathletes do with these stretch cords. Knowing how hard it is just to reach the other end in a 25y pool I doubt many would get there-- but if they can get there then raw power isn't the limiter to their performance.
For LS specifically, I don't think he knows how to output enough power to complete the stretch cord 25 (not that he's not capable of it, specifically he doesn't know how). I don't think he generally knows how to swim that hard without flailing. I keep remembering one of his videos where he did 10x200scy on 2:30 going for best average. At the end of the set he was upset with his performance so he literally did the whole thing again! And went faster! Anyone who knows how to actually swim hard would be totally gassed! I've done this exact set several times and I know I can't just take a 5 min break and go faster the second time around.
I think another good way to measure if pulling power or leg drag is an issue is using a swim parachute with a pull buoy (and maybe paddles because the 'chutes are hard).
lots of good stuff their, we use lots of parachute and TB's and paddles, which do give you a feel of load but can it be measured well.
here is an example.
guy 45 years old pool hard effort for 300 m 6:08 , 1:55,2:00 2:13.
wetsuit swims 1:45, 1:47, 1:47
female 45 years old hard effort for 300, 6:05 1:58, 2:00, 2:05
wetsuit swims 1:55, 1:55, 1:55
He had much more forward pressure but drag was high and increased as timing with breathing making it harder due to air intake.
She has great float but lacks any arm loading and forward pressure. struggles to get any speed but can float to a 2:00 / 100m wetsuit swim easy.
they have different goals not just had pressure and work harder. how can you tell both of them increase propulsion they think they are already at max force!!!
THIS IS WHY PEOPLE HATE SWIMMING!!!!
Technique will always last longer then energy production. Improve biomechanics, improve performance.
