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?

When I got my horrible reading of 153 LDL this past June (I'm 42), I had been training hard recently in swimming for Nationals. When I got the bad reading, I started running again. Unfortunately, I only have had time to run an average of 5 miles per week. I did not change my diet. I did not lose weight. My LDLs were measured the other day and have dropped to 139.
That's exactly what I was looking for--thanks! I don't want to alter my diet (I swim to eat!), but adding some jogging in is doable...albeit painful, mentally speaking.
