Body composition and swimming

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?

  • hofffam How do we replace glycogen. We originally did glycogen replacement in the 50s by consuming Wheatgerm Oil then switched over to Vitamin E to replace Wheatgerm Oil. We were also told that there was no sense taking Wheat Germ Oil or vitamin E if you were not working out hard. We were also told that Iron depleted Glycogen. Are there any major changes in the advice we received. Eventually your body will replace glycogen from other energy stores in the body and from dietary carbs,however that is not good enough if you are going to train 2 days in a row.If you are, you need to start getting carbs within 30 min of finishing your workout,ideally in a 4:1 carb to protein ratio(you need the protein for muscle repair.)During this time your body will preferentially ship the glycogen to your muscles.Remember"you eat today for your workout tomorrow." Vit C and E and other anti-oxydents are important because the increased metabolism of exercise increases free radical formation.
