Impact of acute exercise intensity on pulsatile growth hormone release in men.

What Was Tested

Researchers studied Exogenous HGH, sermorelin & older GHRPs (why they're passed over) in this randomized controlled trial publication.

To investigate the effects of exercise intensity on growth hormone (GH) release, 10 male subjects were tested on 6 randomly ordered occasions [1 control condition (C), 5 exercise conditions (Ex)].

Why It Was Studied

Integrated GH concentrations (IGHC) were calculated by trapezoidal reconstruction.

Who Took Part

The abstract describes 10 subjects taking part.

PubMed indexes the participants as adults, men only.

How the Study Was Run

The design is described as randomized.

The subjects 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.

Serum GH concentrations were measured in samples obtained at 10-min intervals between 0700 and 0900 (baseline) and 0900 and 1300 (exercise+ recovery).

What Was Measured

The subject headings attached to it are Body Mass Index, Human Growth Hormone, Lactic Acid, Physical Exertion, Respiration and Spirometry.

What This Means in Plain Language

The paper is a randomized study of Exogenous HGH, sermorelin & older GHRPs (why they're passed over) in 10 subjects.

With fewer than 40 people, it is a small study, so it is better read as an early signal for further research than as a settled answer.

The publication is from 1999 (Journal of applied physiology (Bethesda, Md. : 1985)), a journal based in United States.
