Green Tea for Muscle Protection? GTE Increases Satellite Cell Proliferation & Differentiation, Slows Disuse-Related Atrophy, Does not Promote Hypertrophy in Aged Rodents

Green tea as a magical muscle preservative for injured athletes? "GTE increased satellite cell proliferation and differentiation, decreased oxidative stress and the abundance of Bax, a proapoptotic protein" (Alway. 2014) - that's the initially exciting result of a recent study from the West Virginia University School of Medicine and Abbott Laboratories . What is not exactly as exciting, though, is how the sentence continues, i.e. "yet this did not further improve muscle recovery in reloaded muscles" (Alway. 2014). Sounds contradictory, right? Well, before we get deeper into the discussion of the results, let's briefly recap how Alway et al. arrived at these insights, i.e. how exactly the experiment looked like and which experimental evidence it generated. The scientists from the West Virginia University School of Medicine tested the hypothesis that green tea extract (GTE) would improve muscle recovery after reloading following disuse. In men and wo...

Creatine Cycling - Yes or No?

In a review ( Wallimann. 2010 ) of the effects of creatine on muscle function, Prof. Dr. Theo Wallimann suggests that in view of the results of rat studies, the old hypothesis that creatine has to be cycled to be effective, needs further investigation before it may eventually be discarded: [...] we have found that chronic creatine supplementation of rats, at very high dosage, down-regulates in vivo the expression and/or accumulation of the CreaT in skeletal muscle , but not in brain and heart [58]. Although the amounts of creatine taken by athletes, 20 grams / day during a 10 days loading phase and 5 grams as a maintenance dose during the following three months (amounting to approximately 0.1 gram of Cr /kg body weight/ day), is significantly lower than the amounts given in the above experiments to the rats (approximately 0.5 grams /kg body weight /day), the finding made with laboratory animals nevertheless may have consequences with respect to creatine supplementation sche...
