Mitochondria are the power source of your cells. Their primary role is to convert the nutrients we consume into energy and the production of adenosine triphosphate or ATP. ATP is then used by our cells to facilitate a range of functions from breathing to exercising. When the size and number of mitochondria is increased they can more efficiently convert energy into ATP which allows more energy to become available to the target muscular system. The more mitochondria an athlete possesses, the longer and faster they can train or compete. Also your system uses more fats and sugars around the clock which is paramount for weight management and preventing diabetes because mitochondria never rest.
Stimulating Mitochondrial growth
Mitochondrial growth is stimulated the same way we stress our bodies through exercise. Stress your body, recover and then it adapts or becomes a little stronger the next time. It’s pretty similar in the development of mitochondria. When current levels of mitochondria are inadequate to meet an imposed demand, our system responds by building mitochondria density. We have to give our system a reason to do it. We have to challenge our cells. And of course the drawback is when you stop training your body has no reason to maintain a high level of mitochondria so they eventually get broken down in the body.
