We tend to associate big muscles with more strength and power. But research has found that at the cellular level, the well-defined big muscles of bodybuilders do not perform so well against those of power athletes (such as weightlifters, powerlifters or sprinters, sports that require important forces to be rapidly developed ) And even against individuals who do not train at all. This research, published in Experimental Physiology, was carried out on individual muscle cells taken from a group of volunteers comprising 12 bodybuilders, six athletic athletes and 14 control subjects (medium, physically active but not training With weights). This directed research, by Hans Degens of the University of Manchester, stimulated the cells and assessed the size and rapidity of the fo...
