NCT04122209
The participants will visit the laboratory on 3 occasions, once for a preliminary visit and a further two occasions to complete experimental trials in a randomised order. The experimental trials will consist of cycling under two conditions; HIIE-First followed by Continuous (Trial-A) or Continuous-First followed by HIIE (Trial-B). Participants will be asked to standardise their diet for 24-hours and complete an overnight fast prior to visiting the laboratory. Participants will then complete 60-min of cycling split throughout the day into two 30-min bouts, HIIE or continuous cycling before breakfast followed by a 3.5 hour rest period before completing their remaining 30-min HIIE or Continuous cycling before lunch. Each experimental trail will last approximately 8 hours and begin at 08:00am. Throughout the trial measurements of subjective feelings of appetite, gastric emptying rate, substrate utilisation and regular blood samples will be taken. Post-trial nutritional and well-being questionnaires will be collected at 24-h post. Study hypothesis 1. The order in which continuous and HIIE is undertaken will result in differences in gastric emptying rate after ingesting a semi-sold lunch? 2. Depending on which mode of exercise is undertaken first will result in different gastrointestinal hormone responses, metabolic responses and appetite responses throughout the trial day? 3. Will the order in which different modes of exercise, undertaken within the same day effect nutritional intake and well-being 24-h after both exercise bout have been completed? 4. Is substrate oxidation effected by the order in which multiple exercise bout of different modes are undertaken within the same day.
NCT02928874
Using an integrated approach, this study examines multiple eating traits concurrently under states of hunger and satiety. It examines the impact of short-term appetite and intake regulation on longer-term energy intake control and weight development in a cohort of ethnically diverse normal-weight and obese boys and girls with different familial predispositions to obesity.
