"There are amazing CAT scans contrasting the muscularity of triathletic and sedentary elder men. It is apparent that destroying your body in a triathlon can, at least, maintain your muscularity. Or, perhaps the difference is completely due to a genetic aberration whereby the above-average muscularity of the elder man merely enables him to destroy his body in the triathlon. Of course, it is also true that such activities are sarcopenic. "
I had not thought of that when I saw the study but logically he is right. There may be survivor bias going on. Those still training at 70 are those that have survived....how many have not managed to make it that far through injury or whatever? What can we really conclude from that study?
