The objective of this study was to examine the effects of 16 wk endurance training on spontaneous 12-h overnight GH secretion in adults with the metabolic syndrome. 34 adults with the metabolic syndrome were randomized to one of three groups for 16 wk: no exercise training (control), low-intensity exercise training, or high-intensity training. Both exercise training conditions augmented within-group nocturnal GH AUC pretrain to post-training and these changes were also greater than the changes in the control group. The change in nocturnal GH AUC was inversely associated with the change in fat mass across the entire sample but was not significantly associated with the change in abdominal visceral fat.
Sixteen wk of supervised exercise training in adults with the metabolic syndrome increases spontaneous nocturnal GH secretion independent of exercise training intensity.
