Re: RC: Re: Re:overweight an issue? - Weight vs. lean mass





Educated guess-wise, would the same hold true for shorter distance anaerobic
events like 25 mile rides?  Since generally the 25 mile horses/riders are "on
average" not in as good a physical shape?

That may work on the treadmill, but under real conditions at a 100-mile race
(where it really counts), it doesn't.  We didn't measure individual heart
rates, but if the horses carrying a heavier rider were at a disadvantage in
recoveries (which, following your theory, they should be), then it follows
that out of several hundred horses, a trend should have showed up, putting
the horses with the heavier riders lower in the placings, lower in
completion rate, fewer miles before a pull or *something*.  We didn't see
that, and believe me, I looked.  It might show up in shorter, faster races,
where energetics are a little different, but didn't at Tevis.  The only
effect we saw with weight had to do with effect on lameness, but that's a
biomechanical disadvantage, unrelated to metabolism.
