Increasing my weekly yardage seems to have increased my hunger. How can I determine the calories really expended during swims of various lengths or intensities?
And when the office hits the all-you-can-eat lunch buffet, how many laps equate to that second or third serving? (Not giving up the food can justify extra time in the pool!)

There is a formula that is used to determine your aerobic intensity level.
It's is 220 - your age X's(times) .%(Maximum heart rate)
Just a few minutes ago, I did a 30-min speed walk. I'm trying to determine just how fast a "Power walk" makes my heart beat.
My beats per minute was 141. I'm 32 years old.
220-32 x's .75 = 141
I was training at 75% of my Maximum Heart Rate. This is not nearly as intense as running, where most train at 85% or higher.
I don't know why, but at most gyms that I go to, the people who just do endless laps of freestyle look like flabby. Those who include other strokes, seem to look more toned. Freestlyers tend to store fat in their mid-section. The body is using the fat for buoyancy, so it's not going to be burned.
