I saw this on the NatGeo channel the other night. It seems that his lactic acid actually begins to decrease at the time when it is increasing rapidly in mere mortals and causing them to bonk. Now we know how he is able to crank out one amazing performance after another.
huhhhh? You know that in his epic quests, he does eat on the run. Gels, cytomax, etc,etc,etc. His pace doesn't not induce rapid lactic acid buildup. More likely his tank is out of gas, running on fumes. Gets a rush of food. Everything's back to normal.
Hello and welcome to last week!
Yeah, cause bekele would have a certain lactic acid buildup from running 8 minute miles.
Not.
Yeah I just watched this and the superhuman thing is how dumb they are. Dean is an amazing runner because of tendon and muscle durability. They seem amazed that as they continue increasing the intensity that his lactate measurements go down but any competitive runner would have the same response if you gradually increased intensity because your body increases its utilization of lactate as intensity increases (he's basically warming up). Eventually lactate production would outpace utilization and you would see a deflection. They also say this buildup will eventually render his muscles useless. I can't believe people still believe lactate is bad years after it being disproved.
Yes, he has great soft-tissue durability. I imagine some of that is from his training and, perhaps, some of it came from his parents. His biomechanics suit him very well.
Agreed
