Research pick: “Effects of testosterone supplementation on body composition and lower-body muscle function during severe exercise- and diet-induced energy deficit”

Effects of testosterone supplementation on body composition and lower-body muscle function during severe exercise- and diet-induced energy deficit: A proof-of-concept, single centre, randomised, double-blind, controlled trial

For this research pick I’ll be addressing a recent paper by Pasiakos and colleagues [1]. In this study they evaluated the effect of 200 mg testosterone enanthate weekly for a period of 4 weeks during a diet- and exercise-induced energy deficit of 55%. The study was a randomised double-blind controlled trial and showed that the

Research pick: “Resistance training volume enhances muscle hypertrophy but not strength in trained men”

For this research pick I’ll briefly address a study which recently came out by Schoenfeld and colleagues. The study evaluated the effects of training volume on muscle hypertrophy and strength [1]. Schoenfeld et al. have published a meta-analysis earlier in which they showed there was a dose-response relationship between training volume and increases in muscle

Beta2-agonist terbutaline to increase muscle mass

For this research pick I’ll go over a recent trial which investigated the effect of terbutaline on body composition in healthy men. Beta2-agonists like clenbuterol and terbutaline have long been thought to increase muscle mass. A wealth of animal research clearly shows this, however most trials in humans fail to demonstrate this. The obvious reason

Latest meta-analysis on beta-hydroxy-beta-methylbutyrate (HMB)

In this research pick I’ll briefly go over a recent meta-analysis published in Journal of Science and Medicine in Sport named Effects of beta-hydroxy-beta-methylbutyrate supplementation on strength and body composition in trained and competitive athletes: A meta-analysis of randomized controlled trials [1]. I’m a bit amazed by the amount of research still done on HMB.

Is metformin bad for gaining muscle mass?

This will be my first article as a ‘research pick’. I’ll try and somewhat regularly write brief articles on new studies published in the literature or discuss certain topics I see floating around on social media. For this first research pick I’ll discuss the drug metformin as I’ve seen this floating around on Facebook over
