Effects of Exercise Intensity on Energy Intake, Appetite and Enjoyment in Overweight and Obese Females

Not Applicable

Completed

• Conditions: Overweight and Obesity

• Registration Number: NCT04437550
• Lead Sponsor: Ohio University

Brief Summary

Interval exercise involves short bouts of high intensity exercise interspersed with periods of lower intensity exercise. The benefit is that a shorter total duration of exercise may be required to achieve cardiovascular benefits similar to or even superior to traditional longer bouts of steady state endurance exercise. However how this type of exercise affects appetite and energy intake, particularly in overweight and obese females is not well known.

This study involves two trials of exercise, one at high intensity and one at low intensity, followed by a buffet lunch, in overweight and obese females.

Primary Outcome Measures

Name	Time	Method
Change in appetite	immediately pre-breakfast, immediately post-breakfast, immediately post-exercise and immediately pre-lunch	measured via circulating hormones leptin and acylated ghrelin
Change in energy expenditure	immediately pre-breakfast, immediately pre-exercise, during exercise, and immediately post-exercise.	caloric expenditure measured via indirect calorimetry
Change in energy intake	immediately post exercise	measured via standardized lunch
Change in subjective hunger	baseline, immediately pre-exercise, immediately post-exercise, immediately pre-lunch, and immediately post-lunch	via visual analogue scale 100 mm, higher scores indicate greater hunger
