Fuel use during exercise in fit adults
This study looks at how your body uses fuel (carbohydrates and fats) during exercise, and whether that is different in males and females. If you are a healthy, active adult who regularly exercises, this research could help you understand your own body's energy systems.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You exercise often: at least 150 minutes per week of moderate-to-vigorous activity (like brisk walking or jogging), plus 3 to 5 structured workouts each week.
- Your fitness level is good or better for your age and gender, as measured by a cardiorespiratory fitness test.
- Your body mass index (BMI) is between 18 and 27, which is in the healthy range.
- Your weight has been stable (within about 4.4 pounds) for the past 6 months.
- You are a non-smoker and not using tobacco products.
- If you are female, you have regular menstrual periods and are not using birth control pills or have stopped them for at least 3 months.
- You do not have certain health conditions like PCOS, endometriosis, heart or metabolic diseases, and you are not pregnant, breastfeeding, or menopausal.
