Just a quick thought on your point of the swim stroke. In your post, you

wrote:

" I cited the swimming study because in a swim stroke, the swimmer is

moving through the water (origin is moving towards insertion), not

remaining idle while pushing water away (insertion moves from

origin). Is this not correct? I suppose it is incorrect if the

swimmer's stroke is inefficient in which case all bets are off. "

I know what you said about the swimmer moving through the water toward the

insertion is true, but just one more thing to think about. The swimmer

doesn't have anything completely solid to hold on to. So, in effect, aren't

both the origin and insertion moving towards each other? I mean, insertion

is mostly stationary, but is there not some movement in the opposite

direction of the swimmer since water is not a solid? Basically, I think

you've got a good point, but just something to think about.

That all depends on how efficient the stroke is. In a perfect world,

the hand does not move through the water at all during the " pull "

phase. Water is only as solid, rather water's resistance is relative

to the amount of force trying to move it. If the swimmer's stroke is

100% efficient, then the water is practically solid. We are getting

into technique issues. The point is that if one has to choose which

exercise will help the swim stroke the most, the pull-up is the

obvious choice. You are absolutely right though in your post.
