The purpose of this study is to investigate the effect of interrupting prolong sedentary
behavior with interval exercise on postprandial metabolism following a high fat glucose
tolerance test.
behavior with interval exercise on postprandial metabolism following a high fat glucose
tolerance test.
All subjects complete two trials in a randomized crossover design, with each trial occurring
over 4 days with a minimum of seven days between trials. The first two days of each trial
serve as a control period allowing for familiarization and the control of physical activity
and calorie consumption prior to the intervention. Following each control period, subjects
then perform one of the interventions on Day 3. The interventions consist of either
eight-hours of prolonged sitting, or eight hours of sitting interrupted every hour by five
sprints lasting 4 seconds each using the interval exercise. On day 4, all subjects will
undergo a high fat glucose tolerance test to determine the body's ability to clear
triglycerides from the blood as well as insulin/glucose response and substrate oxidation.
Blood samples will be assayed for the previously mentioned substances and postprandial gas
collection will be analyzed via indirect calorimetry.
