Similar Assertions

In teen boys, short bursts of intense exercise mainly lower free fatty acids in the blood, while steady, moderate exercise changes more types of fats—including sphingolipids and phospholipids—suggesting different kinds of workouts affect the body’s fat processing in different ways.
