How do you know that is why he leaves others in the dust, vs him just being more talented, or training more, or training smarter, or just setting higher goals than the last generation of endurance runners?
Also you should keep in mind that while there is at least a plausible story you can tell about > 5 hour endurance efforts benefiting from some kind of fat burning approach, from 5k to marathon, you absolutely want to be burning glucose if you want to go as fast as you can go. This is unambiguous.
- HorizonXP 9y agoI agree with the speed aspect, but I wish there were better studies that actually tested this. I realize that "explosive" power is diminished when you're burning fat vs. glucose, it would be interesting to know by what amount. Moreover, is it something that normal people need to know about or is it something that occurs at the extremes of performance? In regards to your first point, I mean, in the video, he stated that he used to try running with the glucose packets and he stated that he got sick trying to keep it all down, and it really slowed him down. It's anecdotal evidence of course, but I wasn't trying to present as anything other than that. :-) Edit: Holy run-on sentence. I'm going to leave it for posterity.
- jackmott 9y agoThe range of aerobic power that people put out is pretty huge, its possible that at the extreme low end, having no glycogen to burn wouldn't be a limiter, but certainly at the moderately trained average joe level, it is still a limiter. But early on, you don't need to worry much about it, just get out and move every day. If you keep it up for a year or two, and want to get faster, you can start adding things to be neurotic about =)
