Overview
Brief Summary
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.
Detailed Description
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.
