bloating, OI, gastrointestinal feelings, flatulence
Although exercise commonly induces a transient reduction in appetite following a session of exercise, long-term exercise is associated with increased hunger and energy compensation [Dietary fibre is one of the primary components of food associated with enhanced satiety [Despite a reduction in subjective hunger ratings, we did not identify a decrease in EI between the two conditions. The day following the exercise session, approximately 12 h after the bout of exercise, we identified a trend towards a 67 kcal reduction in ad libitum breakfast intake with OI. Our study was unique with the assessment of an ad libitum breakfast meal following an evening exercise session. Previously conducted research has traditionally investigated the impact of an acute dose of ITF, consumed in the morning, on ad libitum intake with a lunch meal, assessed ~4 h after fibre ingestion [Exercise sessions have been demonstrated to transiently alter appetite-regulating hormones, with increases in GLP-1 and PYY and reductions in acyl-ghrelin [Relative to changes in appetite, the impact of OI on gastrointestinal feelings was more pronounced. Compared to baseline measures, OI increased flatulence and led to within-condition increases in abdominal discomfort and rumbling the morning after the exercise session. Similar findings have been reported in other acute studies. In 22 healthy women, given 4 different types of fermentable fibre, bloating and flatulence increased 24 h post-consumption, with oligofructose inducing the greatest increase in GI symptoms [This study is not without limitations. The first limitation centres on the absence of a non-exercise control condition. Without this condition, it was not possible to assess interaction effects between the exercise session and ITF consumption. Secondly, this study incorporated 3-day food records to assess EI. Food records are subject to misreporting and recall bias [
