Similar relative energy intakes were observed in males and females, suggesting that acute exercise is equally effective for both sexes. Meta-analyses can be useful to quantify the effects of an intervention with greater precision from a pooled estimate.

Despite our best efforts, we cannot guarantee that we captured all the relevant studies for this review.

For example, despite finding substantial heterogeneity amongst studies in which deivhton 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.

We can only speculate the effects ghrelin has on appetite and food intake as not all studies included these measures in their protocol. Mean BMI was included as a moderating variable, as a negative association exists between study mean BMI and acylated ghrelin concentrations [ tyesis ].


Kevin has wider interests in the topics of exercise metabolism, ergogenic aids, and sports performance.

In thesid study, after four days of consecutive exercise, females experienced an increase in acylated ghrelin, whereas males showed no change [ 30 ]. The software calculated the pooled standardised difference in means to determine the effect size [ 17 ]. The standardised reduction in acylated ghrelin for exercise versus control conditions was found to be 0.

The majority of studies recruited participants of the same sex. The included studies are summarised in Table 1.

Journal of the Royal Army Medical Corpsvol. 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.

If standard error of the mean SEM was reported, it was converted to standard deviations [ 16 ]. Future Science OA https: Frontiers in Nutrition https: Indexed in Web of Science. Data shown is pooled from the current review and from a previous review [ 15 ].

Appetite, energy intake and PYY responses to energy-matched continuous exercise and submaximal high intensity exercise. The average BMI of the participants in this review was Subsequent researchers confirmed these earlier findings [ 5 — 9 ]. Two members of the research team JAD and KD independently selected the studies for inclusion in the meta-analysis and later compared notes to reach a mutual consensus.


Between 7 and 19 participants took part in each study mean 12 participants see Table 1 for summaries of study protocols. 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.

British Journal of Sports Medicine https: Kevin’s personal research investigates the effects of exercise thhesis nutritional interventions on appetite regulation, energy balance, and metabolic health in a range of populations. For this reason, a random effects model was chosen to conduct the meta-analyses [ 27 ]. Of these, million men and nearly million women were obese [ 1 ].
