After being informed about the study details and possible risks and benefits, 15 overweight/obese and 15 lean participants gave written informed consent and were then screened and enrolled in the study. All participants then gave a muscle sample and ate a calorically controlled breakfast. Participants completed ~1 hour of cycling exercise on a stationary bike and gave a second muscle sample 4 hours after eating breakfast.
The purpose of this study is to determine the ability of acute exercise to regulate fat metabolism in muscle of overweight and obese people compared to lean people.
