J Strength Cond Res 36(8): 2194-2197, 2022-The aim of the present study was to examine the effect of an anaerobic exercise test on growth hormone (GH) secretion in children with overweight and obesity compared with children with normal weight. Fifteen children with overweight (body mass index percentile [BMI%ile] ≥8595) and obesity (BMI%ile ≥95) and 10 children with normal weight (BMI%ile585) participated in the study. Subjects performed a modification of the Wingate anaerobic test (WAnT), with 10 bouts of 15-second cycling separated by 1 minute of rest. Blood samples for GH and lactate were collected before and 15, 30, 45, and 60 minutes after the beginning of the exercise test. There was a significant increase in GH levels following the modified repeated WAnT in both groups, but the increase in GH levels was significantly greater among the normal weight children compared with those with overweight and obesity ( p0.003). Seven of the 10 subjects with normal weight had GH increase above the threshold for GH sufficiency compared with only 2 subjects with overweight and obesity. Growth hormone response to the modified repeated WAnT was significantly reduced among children with overweight and obesity compared with those with normal weight. Anaerobic interval-type training may not be a sufficient exercise alternative to stimulate appropriate GH levels among children with obesity. |
