The Five Biggest Contradictions in Fitness

Itís no secret that when people contradict themselves, it has the effect of making the flaws in their actions or statements seem glaringly obvious. But what about when WE ourselves get caught contradicting ourselves by someone else?

    True Or Fasle Doesnt Seem Right (hiit)

    Found this link on Supertraining-- it points to an MFW discussion regarding interval training specifically for fat loss.

    I've been saying for awhile now that shorter, harder intervals are better for fat-burning than using 20 or 30 second bursts, and this seems to lend to that argument, but with a bit of a twist.

    The study notes that, given equal treadmill speed and work duration, fat oxidation was 3 times lower in the group that used 24 second work intervals and 36 second rest intervals, compared to a group using 6s/9s ratios.

    "The decline in muscle oxygenation during work was correlated
    with mean lactate concentration (r = 0.68; n = 12). Lower
    levels of fat oxidation occurred concurrent with accelerated
    carbohydrate metabolism, increases in lactate and pyruvate and reduced
    muscle O(2) availability. These changes were associated with
    proportionately longer work and recovery periods, despite identical
    treadmill speed and total work duration. The proposal that a metabolic
    regulatory factor within the muscle fibre retards fat oxidation under
    these conditions is supported by the current findings."

    The discussion goes on to mention myoglobin, the oxygen-binding protein in muscle. Myoglobin provides short bursts of oxygen in anaerobic conditions. That seems to be the key here; lactate blocks fat oxidation, leaving myoglobin to fuel the oxidative process. Once it gets used up, fat utilization is shut off in favor of glycogen metabolism.

    Now, I'm not exactly sure what protocol was used in the study mentioned; I also don't know what "optimal" work:rest ratio exists. However, it is compelling information to keep intervals short and hard, using ample rest periods.


    there saying 15 second sprinting intervals is better than 30 or more... is this true... feedback please
