12 weeks of combined exercise is better than aerobic exercise for increasing growth hormone in middle-aged women.

What Was Tested

This randomized controlled trial looks at Exogenous HGH, sermorelin & older GHRPs (why they're passed over).

The purpose of this study was to examine the effects of combined exercise training on growth hormone (GH), insulin-like growth factor-1 (IGF-1), and metabolic-syndrome factors and determine whether the changes in GH and/or IGF-1 induced by exercise correlate to the metabolic-syndrome factors in healthy middle-aged women (50-65 years of age).

Who Took Part

The age groups tagged for this paper are middle-aged adults and older adults, women only.

The participants were randomly assigned into an aerobic-exercise training (walking + aerobics) group (AEG; n = 7), a combined-exercise training (walking + resistance training) group (CEG; n = 8), or a control group (CG; n = 7).

How the Study Was Run

The researchers set it up as a randomized study.

Random assignment meant chance, not the researchers, decided who got Exogenous HGH, sermorelin & older GHRPs (why they're passed over) and who got the comparison, which limits bias.

What Was Measured

PubMed files the paper under topics including Aging, Body Composition, Human Growth Hormone, Insulin-Like Growth Factor I, Metabolic Syndrome, Postmenopause and Resistance Training.

What This Means in Plain Language
