Inactivity Duration on Lipid Metabolism

The purpose of the study is to investigate the effect of different periods of physical inactivity on postprandial lipid metabolism in the morning after exercise by measuring plasma triglyceride levels and fat oxidation (burning). The study is a crossover intervention with all healthy participants performing three trials varying in length of physical inactive (12 hours, 24 hours, and 36 hours). All trials include a physical activity control phase (\>10,000 steps/24hr), a physical inactive phase (\<1,000 - 1,500 steps/12hr), a moderate intensity cycling session, and a high-fat tolerance test.
