Study Confirms: Acute Post-Exercise Myofibrillar Protein Synthesis Is Not Correlated with Resistance Training-Induced Muscle Hypertrophy in Young Men

Written by | published on

FSR ≠ more muscle = no news for ya! For the average SuppVersity reader the sentence "Acute Post-Exercise Myofibrillar Protein Synthesis Is Not Correlated with Resistance Training-Induced Muscle Hypertrophy in Young Men" is not just the title of a recent paper in the open access journal PLOS|ONE, it's also the experimental verification of a claim I've made in almost all my articles about the acute effects of certain training modalities and/or supplements on myofibrillar protein synthesis and the corresponding increases in muscle size some people appear to expect from a 2h-long 10% increase in fractional protein synthesis ( learn more ). UPDATE: There is new data  that extends the results of the study at hand and indicates that there is  a link between MPS and muscle gains, after the initial adapation response to exercise. And yes, practically speaking these findings imply that we have to question the real world significance of all the neat studies on the "...

Image 1: Not as realiable as bloodwork, but a valid first indicator of testosterone levels and metabolic health in general (image from Millionlineincome ) I have been writing about getting hormones tested before. And if you listened to Thursday's episode of Super Human Radio and tuned in even before I was on, you will have heard Dr. Crisler from "All Things Male" talk about the paramount importance of optimal testosterone and free testosterone levels on physiological and pyschological health of the purportedly "stronger" sex (yeah, I am talking about us, guys ;-) If that got you interested or you suspect, for whatever reason, to have low testosterone levels, but are unwilling or unable to spend money on a blood test, you may well be interested in the results of a study that was published in the May issue of the Asian Journal of Andrology ( Alan. 2011 ). Alan et al. who investigated the relationship of age, adiposity ...

Endurance Exercise Turns Out to Be More Manly Than You May Have Thought: 30 Minutes on the Treadmill Raise Muscular Dehydrotestosterone (DHT) Levels

Figure 1: Molecular structure of dihydrotestosterone (DHT) (from Wikipedia) I assume jogging is not what crosses your mind, when somebody is talking about "manly" exercises!? DHT, the acronym for dihydrotestosterone , on the other hand, is what experts like Dr John Crisler (from allthingsmale.com) hold responsible for all things male. So, if, as a recent study ( Aizawa. 2011 ) published in the Journal of the American College of Sports Medicine reports, running on a treadmill for 30 minutes, 5 times a week increased dihydrotestosterone levels in skeletal muscle of male rats, it is pretty likely that moderate jogging can trigger similar hormonal changes in men and thus render them "more manly". What Aizawa et al. found was that an increase in "mRNA expressions of 3[beta]-hydroxysteroid dehydrogenase (HSD), aromatase cytochrome P450 (P450arom) and 5[alpha]-reductase in the skeletal muscle of trained rats" if compared to sedentary controls. These c...
