Do anabolic nutritional supplements stimulate human growth hormone secretion in elderly women with heart failure?

What Was Tested

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

Therefore, in this study the researchers aimed to investigate the effect of nutritional supplementation on HGH production in elderly women with heart failure.

Why It Was Studied

Growth hormone treatment has gained attention over the past decade as a treatment for heart failure.

However, studies investigating the effect of amino acid (AA) supplementation show conflicting results.

Who Took Part

PubMed indexes the participants as older adults and people over 80, women only.

How the Study Was Run

The design is described as randomized 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 the crossover set-up each of the participants took both Exogenous HGH, sermorelin & older GHRPs (why they're passed over) and the comparison in turn, acting as their own control.

Plasma HGH concentration was measured before and for 4 h following ingestion of a mixture of protein, carbohydrate, and fat or an AA beverage.

What Was Measured

Topics PubMed links to this paper include Anabolic Agents, Arginine, Dietary Supplements, Heart Failure, Human Growth Hormone and Lysine.

What This Means in Plain Language
