"Elite endurance athletes commonly have mutations that result in the loss of the protein α-actinin-3, which is a major component of fast-twitch muscle fibers. Loss of α-actinin-3 is associated with reduced power, increased endurance capacity, and enhanced response to endurance training.

In this issue of the [i]Journal of Clinical Investigation, Kathryn North and colleagues at the Murdoch Children's Research Institute report that the loss of ?-actinin-3 in fast-twitch muscle fibers, results in compensation by ?-actinin-2. The presence of ?-actinin-2 in fast-twitch muscle contributed to reprogramming these muscles through increased calcineurin signaling.[/i]

This study provides insight into how mutations in the gene encoding ?-actinin-3 promote skeletal muscle adaptations that are advantageous to elite endurance athletes."

So, endurance runners naturally have microscopic aerobic muscular advantages to their muscles.

It could be a chicken before the egg or vice versa scenario.

Endurance runners need less muscle mass sucking up all their oxygen while sprinters need explosive fast twitch fibers to get off the blocks quickly.



"Have any of you seen how Mitrione manhandled Fedor at Bellator 180? Fedor should just quit fighting, he was once the best (always will be IMO) but his fighting mileage has caught with his old age. "

Fedor was my favorite heavyweight of all time but his avoidance of better competition and "drug testing" really made me lose respect for him. I have no doubt that fedor was using PED's, which is fine, most of his competition was as well in the pride days but still, it sits poorly with me.
If he would have fought modern day heavyweights, his poor fundamentals would of cost him everything, he got away with it when fighting the likes of NOG, Fijita, sylvia, etc. But had he been forced to fight the better stand up fighters of todays generation with their superior tdd and BJJ, it would of happened sooner than later. Which is what you saw in the end against Hendo, Mitrione, Big Foot, Werdum etc.
What I would of loved is to see him fight at LHW and have wars with Rampage, Shogun, Wanderlei, Arona, Guy and Hendo back in the prime Pride days. Reply
