Guest guest Posted September 4, 2004 Report Share Posted September 4, 2004 Endurance training has the bad effect of converting fast twitch to slow twitch, but the only way to build capacity is by endurance training. Perhaps another reason why world class runners specialize. I try to keep what little fast twitch I have hanging around by playing basketball, although these days my lack of quickness and diminished mass leaves only gray matter and a decent outside shot as useful tools. I found it amusing that last weekend it was the 30 something kids who were complaining about running full court. :-) FWIW I think the big drug Co.s developed some growth hormone related medicines in search of the elusive " youth " pills but it didn't work as expected. Apparently aging is a multi-faceted thing. Hard to attack with a single vector mechanism. CR is the best shot for at least slowing it down... maybe stem cell for rework and repair.

" On a personal note, I try to keep my HGH supply high by ending my treadmill runs with a 150 yard " sprint " . Read somewhere that high intensity exercise promotes the production of HGH but I don't know how effectively it does this. Anyway the treadmill " sprinting " at least tends to break up the monotony.
