Concentric hypertrophy is a hypertrophic growth of a hollow organ without overall enlargement, [1] in which the walls of the organ are thickened and its capacity or volume is diminished. Sarcomeres are added in parallel, as for example occurs in hypertrophic cardiomyopathy .
In healthy individuals, resistance training and heavy manual labour creates muscle hypertrophy through signalling from mechanical stimulation (mechanotransduction) and from sensing available energy reserves (such as AMP through AMP-activated protein kinase); however, in the absence of a sports or vocational explanation for muscle hypertrophy ...
