Thus, resistance exercises with occlusion lead to increased strength and muscle growth by reducing the supply of oxygen to the muscle, inducing muscle hypoxia, releasing some growth factors. Metabolic stress and the accumulation of substances in the environment seem to be responsible for the increase in the secretion of growth hormone (GH), which is a precursor of Insuline like growth factor (IGF-1), which is responsible for protein synthesis, increasing muscle trophism, cross-sectional area and force. As well as myostatin inhibition and increased heat shock proteins.
