Performing resistance exercise before versus after aerobic exercise influences growth hormone secretion in type 1 diabetes.
We compared growth hormone (GH) and plasma glucose (PG) levels in type 1 diabetic individuals performing aerobic before resistance exercise (AR) to when resistance exercise was performed first (RA). In AR, GH secretion declined in late exercise while it rose throughout exercise in RA, resulting in higher GH in RA versus AR at exercise completion. Higher GH during RA may support PG by increasing hepatic glucose production and lipid mobilization.
