How does exercise affect the mitochondria?

Mitochondria are small structures found in most cells. They are often referred as the "powerhouse" of the cell. Mitochondria transform energy from food into cellular energy. Exercise increases the number of mitochondria improving your body's ability to produce energy. In other words, the more mitochondria you have, the more energy you can generate during exercise and the faster and longer you can exercise.

Mitochondria are tiny structures inside cells that are responsible for producing energy. When we don’t exercise, the number of mitochondria in our cells actually declines. Exercising increases the number of mitochondria in the specific muscle groups that are being worked. The end result is that with more mitochondria, you are better able to produce energy and burn fat.

Exercise helps the body make more mitochondria. The more people exercise, the more mitochondria they make.

Mitochondria are the powerhouses of the cells. They do all the heavy-duty work to keep the muscles moving. More exercise means more mitochondria and stronger muscles, so people can be active for longer without getting tired.
