What is your resting heart beat, upon waking up in the morning?
Do intensive swimming result in lower rates than persistent fitness swimming?

... it seems like running I could maintain 150-160 for a while, I rarely get over 120 in the pool; I should start checking more often.
I read in a medical physiology book that hearts rates do not rise to the same peak in swimming that they do in other activities. Dramatically so.
The book was from last century and they were not sure why there was this discrepancy.
The authors believed even though HR was much lower, a person would still get the cardiovascular benefit from exercise intensity. (They were meticulous at stating that this was not proved, though.)
One of the authors was Arthur Guyton - most of the cardiac physiology we deal with is known in some circles as "Guytonian physiology," so I tend to trust his word.
