Richardsk has just put his finger on the issue, for me. If breaststroke is easier than freestyle, what (on land) is freestyle as easy as?

Default Economic efficiency of different swimming strokes

If breaststroke is easier than freestyle, what (on land) is freestyle as easy as?

It is not about easiness.
“The most economic” in this study means that freestyle swimmers of international level spend less energy per 200 meters over a large range of velocities than the backstroke, the butterfly and the breaststroke swimmers of international level.

I want to know about easiness!

I've wondered about the orginal question myself. I usually feel very relaxed for my swims, which average 1.75-3.0k. I occasionally bump it up a bit to pass or just for fun, but recovery time to 'easy freestyle' (relaxed, lots of air)is short, and I don't feel an appreciably elevated heart rate or heavy breathing at all leaving the pool. It seems that all the scientific measures I've seen out there don't really apply to a leisurely economical freestyle, and do wonder what rate of calorie burning is occuring.
Using this calculator http://www.healthyweightforum.org/en...calculator.asp under the swimming categories, a leisure swim burned 436 calories per hour, and light to moderate freestyle laps burned 510 calories. I suspect the lower value applies.

Default Equivalent Oxygen consumption. How?

According to the various links in this thread the oxygen consumption of
Running at 5mph = Swimming 100 meters at 2:15 minutes.

When I run at that speed I breath about 25 times per minute.
If I could swim at that speed, I would be breathing about 15 times per minute.
15=60/(1.3s*3)

How do swimmers make up the difference? Is the breath in water twice as deep? Doesn't feel that way.

BTW, I can easily maintain running at 5mph. I can't even dream of swimming at 2:15min.
