Responses of markers of bone and collagen turnover to exercise, growth hormone (GH) administration, and GH withdrawal in trained adult males.

What Was Tested

The paper reports a study of Exogenous HGH, sermorelin & older GHRPs (why they're passed over), published as a randomized controlled trial.

Sequential studies of exercise, GH administration, and GH withdrawal were undertaken.

Who Took Part

By PubMed's age tags, the people studied were teenagers and adults, men only.

How the Study Was Run

In design terms this was a randomized, double-blind, placebo-controlled and parallel-group study.

Because people in this Exogenous HGH, sermorelin & older GHRPs (why they're passed over) study were split into groups at random, differences between the groups are less likely to reflect who happened to join each one.

As a double-blind Exogenous HGH, sermorelin & older GHRPs (why they're passed over) study, the assignments were hidden from both participants and investigators until the end.

A placebo (an inactive look-alike) gave the Exogenous HGH, sermorelin & older GHRPs (why they're passed over) group a baseline to be compared against.

Groups ran in parallel: each of the participants stayed in one arm throughout.

What Was Measured

PubMed files the paper under topics including Aging, Biomarkers, Bone Development, Bone and Bones, Collagen, Exercise and Exercise Test.
