Running. Does it help your swimming or is it an interesting diversion? A lot of people here seem to cross train with running. (Some are obviously triathletes). USS teams now have their swimmers running. But does running really help swimming?
For me, I'm not so sure. I think it helps a bit on the cardio side and may build leg strength. I do it to tighten everything up, because I like being outside and it gives my shoulders a break. But I'm not sure I wouldn't be better off with more pool time if my body could take it.
There is nothing you can do in a pool to your legs that remotely comes cloose to track sprinting. The foot strike forces in sprinting are astronomical, the turnover rate astronomical, the range of leg motion astronomical, the stresses on tendons are near the breaking point.
OK, go kick a 100 meter all out and come back and make this claim. Air is 1/800th the density of water. I'd much rather run a 100 than kick it all out. I'd argue you have to work much hard in the water.
Runners, meh, yawn.
