Nevertheless, it was extremely difficult to eradicate this problem because all studies were crossover in design rather than separate study arms and we already had to impute a within-subjects correlation for the meta-analysis because study authors tend not to report directly the standard deviation of the mean change. Three studies included standardised meals before the exercise bout [ 13 , 21 , 24 ] and four studies included ad libitum meals after the exercise bout [ 13 , 21 , 22 , 24 ]. A large and statistically significant Egger statistic indicates the presence of a small study effect. Mean BMIs were pooled from studies collected in the current review together with those reported for lean individuals in a recent review by Schubert et al. Subscribe to Table of Contents Alerts.
We found acylated ghrelin to be moderately suppressed by acute exercise, whilst there were trivial effects of exercise on total PYY and total GLP Applied Physiology, Nutrition, and Metabolismvol.
Journal of Obesity
In a recent review, lean individuals showed a small reduction in acylated ghrelin after exercise, whilst total PYY and total GLP-1 showed small increases [ 15 ]. Similar relative energy intakes were observed in males and females, suggesting that acute exercise is equally effective for both sexes.
European Journal of Applied Physiology https: Journal of the Royal Army Medical Corpsvol. All of these had been published or accepted for publication in peer-reviewed scientific journals. Of these, million men and nearly million women were obese [ 1 ]. For example, despite finding substantial heterogeneity amongst studies in which ghrelin and GLP-1 were measured, precise analyses such as one for the presence of outliers could not be performed due to the small number of studies.
A large and statistically significant Egger statistic indicates the presence of a small study effect. Undergraduate Courses Right Arrow. The current review has several limitations. Additionally, studies differed by exercising participants in both fasting and fed states.
Physiology and Behavior https: Alongside limiting energy intake, individuals are advised to take part in regular physical activity. Therefore, these individuals are in an energy deficit, and if maintained over time this could result in weight loss. View at Google Scholar A.
A negative correlation was observed which persisted even deihgton baseline control mean ghrelin concentration was added as a covariate. In one study, after four days of consecutive exercise, females experienced an increase in acylated ghrelin, whereas males showed no change [ 30 ].
European Journal of Sport Science https: Of the 10 trials, one used treadmill walking as the mode of exercise, two used treadmill running, and seven used a cycle ergometer. European Congress on Obesity Vienna AUC calculations were made over the duration rhesis each trial, irrespective of when exercise occurred.
Together, these could further cofound the study of hormonal responses to exercise. Together, six studies met the inclusion kvein for the current meta-analysis Figure 1. The majority of studies recruited participants of the same sex.

Obesity is associated with an increased risk of type 2 diabetes, coronary heart disease, and some types of cancer, as well as strokes [ 2 ]. Study selection criteria were not limited by the duration or observation period after exercise. Find what you’re looking for Find Icon.
The current review found three studies that examined the acute effects of ekvin on appetite regulatory hormones in males, two studies in females, and one study including both males and females.
However, no methodological reason was identified for the relatively high effect size in this particular study. European Journal of Sport Sciencevol.

In lean individuals, acute aerobic exercise is reported to transiently suppress sensations of appetite, suppress blood concentrations of acylated ghrelin AGand increase glucagon-like peptide-1 GLP-1 and peptide-YY PYY. Abstract In lean individuals, acute aerobic exercise is reported to transiently suppress sensations of appetite, suppress blood concentrations of acylated ghrelin AGand increase glucagon-like peptide-1 GLP-1 and peptide-YY PYY.
