Participate in Research at CU Anschutz

Help us learn how morning exercise and nighttime exercise affect the body differently.

You will be asked to attend several screening visits to make sure you are eligible to be in the research study and that it is safe for you to participate. Research study participants will be randomized to exercise either in the morning or the evening. Randomization is like flipping a coin, so you will have a 50/50 chance of being assigned to either morning or evening exercise. Volunteers will have access to the Anschutz Health and Wellness Center Fitness Center and receive a free 13-month exercise program!

Main Procedures Involved: Main study tasks include blood draws, exercise testing, DXA scans, RMRs, questionnaires, and vitals. A DXA scan uses a special x-ray to measure your level of body fat mass and lean mass. An RMR measures the amount of oxygen you use and the amount of carbon dioxide you produce. From these measurements, the number of calories your body uses at rest can be determined.

Duration of Participation: Your participation in this study will be 13 months.
