It's fairly common knowledge that swimming makes for a good cardio workout. Doing sprints is one way to keep the heart running faster. Pushing the distance can do it too as long as it's at some speed. Sounds analogous to the sport of running, right? Well, maybe not so fast.
Buried deep in an article in today's New York Times there is a mention about how one's heart works differently for swimmers than it does for runners. Runners' hearts, the article says, must fight gravity. It must pump the blood vertically up to the head. That's not the case for swimmers. The gravitational fight is not as much of an issue. You are already horizontal in the pool. I'm no medical type, but I'm having no trouble imagining that there's something to that.
OK, so what does this all mean? Does the heart rate for a swimmer working equivalently to the heart rate of a runner mean that the swimmer can put more energy into propulsion, while the runner is putting it just into surviving? I'll have to think on this some more. Thoughts from my readers are welcome.
I do a good bit of lap swimming (see goals - lower left) so I have lots of time to think about it. I routinely see athletic folks who can't swim, or swim poorly + often wonder why I find it so easy - I'm not particularly athletic. This blog is about what I'm learning about swimming dynamics + some fun stuff too.
For your safety, all posts + comments are musings + tips that have worked for me - opinion only. For the record, I strongly suggest following Red Cross swim-safety protocols.

I've checked it out. Looks a little more advanced than that covered in this post. Or is it the same thing?
