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?
Cut down on your night time snacks. Years ago my doctor told me if you are need a little snack eat a couple of soda crackers. If Iwake up starving i do love cheese. 1 oz of cheese and 4 cackers a great snack. If I need something exotic to tingle my taste buds 2 slices of pickled beets. and a half slice of ham.
Thanks for the suggestion, geochuck. Believe me, I don't eat anything like I did 5 or 6 years ago. No night snacks, daily muffins, or donuts on the weekend for me now. I would truly be fat is I ate the way I did back then. I would have been truly fat in college despite all the swimming if I ate the way I did 5 or 6 years ago.
Here is the study I found which doesn't really answer my question, but does indicate that hormonal changes do take place at least on the particular hormones they studied : www.ncbi.nlm.nih.gov/.../8861670
As with many things, I don't think there is a simple explaination. Perhaps the swimming vs. running thing is a combination of difference of calories burned along with changes that take place in primarily anaerobic activity.
