This research study is about how daily activities, behaviors, and fitness affect the health and function of blood cells and their mitochondria, which are the powerhouses of the cells. These small mitochondria inside the cells make energy, and are very important for the health of the body.
Determine the impact of physical activity and obesity status on circulating cells mitochondrial function (e.g., fat vs. carbohydrates combustion capacity, total oxidative capacity, mitochondrial number and proton leak).

RECRUITINGPlatelet mitochondrial respiration and its association with adiposity and peak aerobic capacity in children 8 to 10 years old.
Platelet mitochondrial respiration from isolated platelets will be measured using a flux analyzer. Adiposity will be measured with dual X-ray absorptiometry, and peak aerobic capacity with an incremental cycle ergometer test. measure physical activity
