You may be interested in the research performed by Vsetulová E, Bunc V. "Effect of body composition on physical fitness and functional capacity in obese women". While this is specific to women, you might learn why you cannot conclude that body fat percentage has a relationship with VO2max. Also, adipose tissue is far less vascularized than other tissues, so your cardiac output wouldn't increase if you were to put on more fat mass. An increase in cardiac output would be advantageous and would help improve your VO2max, since Q x (a-vO2) equals VO2max. Keep testing, maybe you'll find the answer that many people want to knowAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-14253811.post-77035951635726910502008-02-14T10:50:00.000-05:002008-02-14T10:50:00.000-05:00sorry i meant not what do you weigh but how tall a...sorry i meant not what do you weigh but how tall are you.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-14253811.post-9664932755530147422008-02-14T10:48:00.000-05:002008-02-14T10:48:00.000-05:00What do you weigh?

I do long-distance swimming and noticed that my lung volume increased substantially from changes in my training.<BR/><BR/>I typically was doing 800m front crawl everyday in at heated pool at 81 F where I had to turn every 25 m, as fast as i could and hitting an oxygen wall where breathing every 3 strokes I ran out of oxygen and had to stop and catch my breath at some point in the run. But I upped my distance to 2.5 miles instead of 800m and did the swim in a 68 F freshwater turning every 200m instead of 25m like in pool. Within a few weeks suddenly no more oxygen problems, I could breathe every 3 strokes for hours at a pace faster than I was able to achieve on my 800 m time. Instead of a 16-17 minute 800 m I was doing an 56 sec 100 m and an 11.5 minute 800 m. Maybe hypothermia helps, when your body is cold you need less oxygen? I think doing long-distance swims in cold water (68 degrees and over 2 miles) greatly increased my lung capacity although mild hypothermia is something I've experienced doing this.<BR/><BR/>I had pushed up to swimming 2.5 - 3.5 miles a day 5-7 days a week when I tore a muscle in my chest. When I had a chest x-ray the doctor asked me if I was a professional long-distance swimmer or a commercial diver. I said a swimmer and he said you have what we call diving lungs, they are very large, expand out very far, but also taper down very far in the chest, and we see it a lot in people like that.<BR/><BR/>I'm sure as I had x-rays from before I began that training regime (2 years previously) that my lungs were not as expanded, they were healthy but otherwise unremarkable. Actually I think it's the 2+mile swim fast & daily in cold water for at least 3 months that does it.Anonymousnoreply@blogger.com
