Lactic acid not the cause of muscle fatigue?
Am curious if anyone else saw this article. Lactic acid buildup doesn't cause muscle fatigue anymore? When did this happen?

A few million years ago. However, it's probably been known by man for quite sometime, perhaps decades. |

Looks like anti-doping agencies will have another class of drug to put on their list.

Re: Lactic acid not the cause of muscle fatigue?
So what causes the pain?
Ischaemia? Tissue oedema and stretch of pain fibres? Local pH alteration and pain fibre stimulation? Others?

What difference does it make? It's not like there's anything you can do about it. |

Once upon a time there was nothing one could do about those chest pains of heart attacks, and people just died. Then science changed everything.

My bad, I didn't realize you were personally a scientist working on some of that "science" stuff to eliminate muscle pain |

Re: Lactic acid not the cause of muscle fatigue?
Yeah, I saw that article in the times earlier this week. My issue is that it doesn't really say anything of revelant importance. It tells us that muscle damage is caused by calcium leaks with the muscular tissue, but it doesn't reveal any sort of information that would change the way people train.
What am i supposed to start bringing Tums along on rides to aid recovery?  |

Re: Lactic acid not the cause of muscle fatigue?
Not sure about muscle damage, but my reading of it was that those leaky Ca channels was partly the explanation for muscle fatigue. Muscle fatigue could be reduced by reducing the "leakiness" of those ion channels, by 10-20%.

That depends on what was the source of stimulation of those pain fibres. You see, that argument only partly make sense as we all know that we train to push beyond our lactic/pain threshold in order to perform better. If we always use pain as the limit of our training and activities, then we are not likely to get stronger and better.
