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

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.

Treatment and study plan

Exercise

Other

high intensity exercise = 15 x 60 s sprints at 85% velocity of VO2max (vVO2max) with 60 s walking at 20% vVO2max or moderate intensity exercise = walking at 60% vVO2max

Primary outcomes

  1. Change in energy expenditure

    Time frame: immediately pre-breakfast, immediately pre-exercise, during exercise, and immediately post-exercise.

    caloric expenditure measured via indirect calorimetry

  2. Change in energy intake

    Time frame: immediately post exercise

    measured via standardized lunch

  3. Change in appetite

    Time frame: immediately pre-breakfast, immediately post-breakfast, immediately post-exercise and immediately pre-lunch

    measured via circulating hormones leptin and acylated ghrelin

  4. Change in subjective hunger

    Time frame: 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
