Maximum anaerobic performance of childhood-onset GH-deficient adults

To date, physical capacity of adults with GH deficiency (GHD) has been studied in terms of muscle strength, contractile properties and aerobic performance. As a result, scanty data are available regarding the maximum anaerobic performance of these patients with reference to healthy controls. Therefore, the objective of this study was to evaluate maximum anaerobic power of adults with GHD and of age-matched controls by two methods, one testing lactacid power (W(c)) through a 15-s-maximal bout on a bicycle ergometer, the other testing alactic power (W(j)) through a vertical jump on a force platform. Absolute W(c) and W(j) values were both found to be 35% lower(P<0.04) in GHD patients than in controls. Similarly, peak pedalling velocity (V(peak)) was 21% lower (P
