On the supply side, you have something like stroke volume x heart rate (= cardiac output) x hematocrit x oxygen saturation; ie. the amount of O2 pumping through per time. On the demand side, you have your collective muscular system's ability to work aerobically (ie. the percentage of O2 extracted from the blood).<br /><br />That's a lot of limiting factors. Surprisingly, breathing is almost never the limiting factor as O2 saturation is almost at 99-100%, even at max exercise. <br /><br />And about the anemia, we could get you some EPO. That would take care of the anemia and you would crush course records everywhere. <br /><br />Seriously, you should get that looked at, unless it's a Quickian exaggeration.Fast Bastard - World's Fastest Hematologisthttps://www.blogger.com/profile/09439674206797439620noreply@blogger.comtag:blogger.com,1999:blog-2796785757974247915.post-70077000167102144092011-08-03T08:36:38.282-05:002011-08-03T08:36:38.282-05:00I think what sea legs girl is trying to say is, &q...I think what sea legs girl is trying to say is, "Why don't you do a post about choking the chicken so we can read btw the lines to see what you think re: heart rate and VO2max?"<br /><br />Personally, I think she should stop trying to put words into Tracizzle's mouth.

You need to get that looked at if you haven't -- not to be alarmist, but it can be an early sign of [potentially treatable] colon cancer, among many many other things.Robynhttps://www.blogger.com/profile/14582049406998358870noreply@blogger.comtag:blogger.com,1999:blog-2796785757974247915.post-57178503586534982302011-08-03T07:24:22.215-05:002011-08-03T07:24:22.215-05:00I think what Fast Bastard is trying to say is the ...I think what Fast Bastard is trying to say is the Tracizzle comment was Fast Bastard.sea legs girlhttps://www.blogger.com/profile/14782712411873234071noreply@blogger.comtag:blogger.com,1999:blog-2796785757974247915.post-91471331307048071862011-08-03T01:18:00.383-05:002011-08-03T01:18:00.383-05:00Ah, crap.

If you look at VO2 max, as a new athlete trains, various parts of their body will develop at different rates. So at one time a given effort will have them gasping for breath. Months later it might be the leg muscles that poop out while the lungs are doing fine.Keithhttps://www.blogger.com/profile/09364395150014197905noreply@blogger.comtag:blogger.com,1999:blog-2796785757974247915.post-63470616799896431532011-08-02T13:22:31.801-05:002011-08-02T13:22:31.801-05:00Steve, very interesting post.

I guess if you looked at him going at VO2max pace, you could say that his heart rate at that moment was a limiting factor. But, then again, if he had more efficient muscle and less fat, as VO2max depends on weight, those would improve his VO2max also. <br /><br />I don't think there is any one thing that is "blocking" your VOmax. <br /><br />Now, if you were anemic, your heart would pound faster to compensate, so in that scenario heart rate would be even more important. But then again, doping with EPO raises one's VO2max as well. I'm confusing myself. We need you to write more abou this, including what a tempo run is. Does anyone really know?<br /><br />Another topic is why the hell are you anemic? That's not normal, unless you are talking very minimal anemia. We need more info on that one.Tracizzlehttps://www.blogger.com/profile/17797130599472465690noreply@blogger.comtag:blogger.com,1999:blog-2796785757974247915.post-86911402408160622672011-08-02T12:02:36.668-05:002011-08-02T12:02:36.668-05:00G: Have you ever thought of using your talents for...G: Have you ever thought of using your talents for something useful? <br /><br />Funny stuff, except the "not getting any... pointless to try" hits awful close to home!SteveQhttps://www.blogger.com/profile/16943650844671498074noreply@blogger.comtag:blogger.com,1999:blog-2796785757974247915.post-66817856640607668112011-08-02T11:56:26.519-05:002011-08-02T11:56:26.519-05:00Through the miracle of judicious editing, I manage...Through the miracle of judicious editing, I managed to make this post less "long-winded and dull" - but may have inadvertently changed its focus:<br /><br /><i>I just had ...this ... long-winded and dull ...
