Lactic acid is not produced by the muscles and it is not the cause of the burning sensation or fatigue in muscles.  "Lactate" is used to buffer the acidosis caused by the build up of hydrogen ions, so your muscles actually use lactate as a source of energy.. Google "Lactic Acid Myth" and you will see what I am talking about.

Just hilariously awful.

horrendously informed. oh the body just 'shuts down automatically' and you collapse the body does not 'shut down' if oxygen is not going to the muscles, that's why its called anaerobic respiration.

He meant the gluteal muscles aka your arse. His english isn't great but I got the message. For those who can't understand him he's basically saying that lactic acid burn can be prevented by ensuring proper blood flow by stretching the muscles well beforehand. Especially the glutes, hip flexors and hamstrings. He mightn't be the best with words but I trust he knows a thing or two about sprinting.

"oxygen pumping enough blood to red blood cells"???????

what the...now i see what a some of you guys are talkin about, it's kind of like he read it from a script.

[dudeguy927]

well, a lesson to learn from the video is proper stretching, some people don't properly stretch, and it costs them. If you do, then good for you

:-)

Wow, this could be a Saturday Night Live skit. What is sad is that he is completely serious.

This man is an ignoramus -- I tried to give him a chance, but he does not know what he is talking about!

The lactic acid does accumulate, but it is the physical damage does causes the so--called rigor mortis (Timothy Noakes, Lore of Running).

The "phosphates" pre--stored in the body are being quickly depleted: it is possible to hold the very top speed only up to 300 yards or about 280 meters.

400 m is 80% pure speed, 10% lactic stamina or speed stamina, and only 10% aeorobic or about.
