What This Study Did, in Plain Language
What Was Tested
This randomized controlled trial looks at Exogenous HGH, sermorelin & older GHRPs (why they're passed over).
Prior research has indicated that the loss of skeletal muscle mass and bone mineral density observed with aging is related to the prominent age-related decline in the concentration of serum growth hormone (GH).
However, there is limited data on the effects of aging on GH responses to acute bouts of heavy resistance exercise (HRE) and aerobic exercise (AE).
Who Took Part
PubMed indexes the participants as young adults, adults and middle-aged adults, women only.
The present investigation examined the effects of a HRE protocol and an AE protocol on immunoreactive GH (IGH) and bioactive GH (BGH) in active young and old women.
How the Study Was Run
The researchers set it up as a randomized and crossover study.
The participants were allocated by chance, so the Exogenous HGH, sermorelin & older GHRPs (why they're passed over) group and the comparison group should start out alike.
Each person switched between Exogenous HGH, sermorelin & older GHRPs (why they're passed over) and the comparison at some point, usually with a gap in between.
What Was Measured
PubMed files the paper under topics including Age Factors, Aging, Exercise, Exercise Test, Human Growth Hormone, Recovery of Function and Resistance Training.
Author keywords: Bioassay, Immunoreactivity assays, Rat tibial line assay and Resistance exercise.

Our Notes on the Compound
Exogenous HGH, sermorelin & older GHRPs (why they're passed over): Constant levels suppress the body's own GHRH, raise somatostatin and dull pituitary response.
