Effects of Brief Exercise Linger an Hour
Just 10 minutes of brisk exercise can trigger metabolism changes that last an hour, new research finds. But people who exercise more than that â those who are fit â get the most benefit even from brief activity. The study included 70 healthy adults. They were put on a treadmill for 10 minutes. Researchers took blood samples before and right after the workouts, and one hour later. The brief exercise changed blood levels of substances involved in metabolism. The body produces these “metabolites” as it burns food for energy. Some of the changes were still apparent in the blood an hour after exercise. Thinner people had higher levels of niacinamide, which is involved in blood sugar control. A substance involved in fat burning was higher in fit people. This suggested they were burning more fat from the same amount of exercise.
