I have determined that when I swim, based on my heart rate, I am burning an enormous amount of calories. The other day, I wore my HR monitor and based on my average HR, time spent swimming, and my weight, I burned 1053 calories. Now, the next day, I ran for 40 minutes and burned 453 calories.
I have noticed that when I just swim over a number of weeks, my LDL cholesterol readings go up and my body fat goes up as well. When I just run and don't burn as many calories (according to my HR monitor) my LDL drops, my HDLs go up, and my body fat decreases. I've noticed this now over the course of 13 years.
Anybody know of any studies out there that might explain this? Why would an activity such as swimming that obviously burns a bunch of calories cause an increase in body fat?

How are you testing cholesterol so often? Are you fasting properly before the tests? If not I think the testing is completely irrelevent.
I have read several studies that show swimming produces lower maximum heart rates compared to running or cycling for similar perceived effort because the water cools the body more effectively. The body produces significant heat during exercise and uses significant energy to cool itself. So the water does the opposite of what Flyqueen posted above.
I easily see the difference in fatigue when the pool water is 80 deg vs. 84 or 86 like my pool sometimes reaches.
