Normobaric hypoxia increases the growth hormone response to maximal resistance exercise in trained men.

What Was Tested

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

This study examined the effect of hypoxia on growth hormone (GH) release during an acute bout of high-intensity, low-volume resistance exercise.

Who Took Part

PubMed indexes the participants as young adults and adults, men only.

How the Study Was Run

The design is described as randomized, single-blind and crossover.

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.

In this single-blind Exogenous HGH, sermorelin & older GHRPs (why they're passed over) study one party knew the assignments and the other did not.

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.

Heart rate, SpO2, and electromyographic activity (EMG) of the vastus lateralis muscle were measured throughout the protocol.

What Was Measured

The subject headings attached to it are Electromyography, Exercise, Heart Rate, Human Growth Hormone, Hypoxia, Lactic Acid and Quadriceps Muscle.

The authors tagged it with the keywords Bench press, intermittent hypoxia, leg press and resistance exercise.

What This Means in Plain Language

The paper is a randomized, single-blind and crossover study of Exogenous HGH, sermorelin & older GHRPs (why they're passed over).

The publication is from 2017 (European journal of sport science), a journal based in Germany.
