Replace on Extreme Endurance Coaching – BionicOldGuy

In his “sweat science” column, Alex Hutchinson reported on some latest research that give an replace on the query of whether or not there are well being points related to extreme endurance coaching. I’ve mentioned this beforehand (here, here, and here) it being a matter of some curiosity to me as I wish to endurance practice so much. The primary research is a recent one from Solar-Yat-Sen Univerity in China [1]. This confirms that though folks that do a excessive quantity of endurance train are likely to have increased calcium scores of their coronary arteries (a sign of arterial plaque), it’s a benign situation as a result of the plaque tends to be secure. This newest research reveals that on long-term follow-up, the high-volume athletes don’t have any larger danger of antagonistic cardiac occasions.

A second study [2] disputes the “J-curve” that has been beforehand reported for all-cause mortality vs. the quantity of train. It’s well-known that train reduces the chance of mortality, however some earlier research have proven that the chance of dying goes again up for excessive quantities of train. That is controversial as some research have discovered this impact however others haven’t. The brand new research highlights a flaw within the methodology of the earlier research that detected a J-curve. Reasonably than monitor the precise ongoing train habits of the folks being adopted, the earlier outcomes estimated the quantity of bodily exercise simply based mostly on a questionnaire administered firstly of the research. Within the current research, the quantity of train was repeatedly tracked for over 30 years in a big (greater than 100,000) pattern of individuals. The “J-curve” was not discovered: train reduces the chance of all-cause mortality, together with excessive volumes of train.

I nonetheless wish to hedge my bets on this. I do a excessive quantity of train however a big share of it’s at comparatively low depth, extra like brisk strolling or equal. I do train at increased intensities, however at a decrease quantity. As I’ve mentioned beforehand (here and here) it is a good mixture of train for efficient coaching, well being advantages, and rest.
