Fig. 4From: Obese adolescents exhibit a constant ratio of GH isoforms after whole body vibration and maximal voluntary contractionsPeak values of 22 kDa- and 20 kDa-GH and the related ratio (i.e., 22 kDa-GH-peak/20 kDa-GH-peak) after the three different protocols of exercise: maximal voluntary contractions + whole body vibration (MVC + WBV), muscle voluntary contractions (MVC) and whole body vibration (WBV). Values are expressed as mean ± SD. *p < 0.05 vs. WBV; op < 0.05 vs. MVCBack to article page
