The effect of acute exercise on pre-prandial ghrelin levels in healthy adults: A systematic review and meta-analysis.

What It Covers

The paper reports a study of Ghrelin, published as a meta-analysis.

Ghrelin is a gut hormone with numerous physiological effects, including the regulation of energy balance, insulin sensitivity, vascular health, and body composition.

Exercise is a therapeutic option that can potentially optimize ghrelin levels.

Who the Included Studies Covered

PubMed tags the participants as both men and women.

The following criteria was determined a priori for article inclusion: (i) the study was a randomized controlled trial (RCT),(ii) exercise was an acute bout, (iii) the exercise bout for the intervention group(s)/condition was structured, (iv) the control group/condition received no exercise, (v) participants were adults age 18 or older, (vi) ghrelin was sampled through blood, (vii) there was at least one baseline measure and one post-exercise measure of ghrelin, (viii) there were at least 3 timepoints where ghrelin was measured while participants were fasted to allow for pre-prandial total area-under-the-curve (AUCtotal) calculation, (ix) participants were healthy with no overt disease, (x) interventions were carried out without any environmental manipulations.

How the Review Was Done

Electronic databases (PubMed, Medline, SPORTDiscus, Web of Science, and Google Scholar) were searched with articles published through August 2020.

What Was Measured

Exercise is a therapeutic option that can potentially optimize ghrelin levels.

PubMed files the paper under topics including Acylation, Body Mass Index, Energy Metabolism, Exercise, Fasting and Ghrelin.
