Duration of Physical Inactivity and Postprandial Lipid Metabolism

United States8 participantsStarted 2024-04-01

Plain-language summary

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 (4 hours, 8 hours, and 12 hours). All trials include a physical activity control phase (\>8,500 steps/24hr), a physical inactive phase, a moderate intensity cycling session, and a high-fat tolerance test.
