Open AccessObese adolescents exhibit a constant ratio of GH isoforms after whole body vibration and maximal voluntary contractions
Growth hormone (GH) is a heterogeneous protein composed of several molecular isoforms, the most abundant ones being the 22 kDa- and 20 kDa-GH. Exercise-induced secretion of GH isoforms has been extensively inv...
