Your mitochondria are tiny working organizations that exist deeply in your cells that are largely responsible for transforming the substrates from your body bands from the food you eat in energy. In terms of metabolism, it is the mitochrondria that actually makes the crucial act of "burning" - in calories and turning them into heat. They are also why exercise and muscle growth are essential for weight loss and sustained health because your muscles are the homes of your mitochondria body. Simply put: The more muscle you have, the more mitochondria you have to burn calories.

But according to a new study, I just published last week in the newspaperCell metabolismIf you are engaged in the wrong form of exercise, you can actually damage your mitochondria's ability to do its job effectively. Learn more about this study and for more news from the tip of physical condition science, make sure you are aware of theA major side effect to sit too much on the couch, says a new study.

The research was directed by Filip Larsen, from the Swedish School of Sport and Health School, who wanted to study the effects of over-training on the body. He and his colleagues tested 11 young people over four weeks using a stationary bike, increasing the intensity of training as they advanced. During the trial, the researchers followed their resistance to insulin and the mitochondrial function of their body.

During the week, participants did training at light high intensity intervals for only 36 minutes in total. During the week two, they went up to 90 minutes. During the week three, they went up to 152 minutes of the leg. The fourth week was a recovery period, with only 53 minutes of training.

In the first two weeks of the study, participants experienced all the usual effects that can be expected of high-intensity training. Their mitochondrial function has improved, among other things.

But in the third week of training, the mitochondrial function of the participants fell from an average of 40% compared to the week two. "After the week with the biggest exercise burden, we found a striking reduction in intrinsic mitochondrial function that coincided with a disruption of glucose tolerance and insulin secretion," says the study.

This is true: the resistance of insulin of subjects is actually goneup. "It's quite similar to the changes you see in people who start developing diabetes or insulin resistance," Larsen explained toThe scientist.

The ability of volunteers to generate power over their cycles has also reproached.

After the third difficult week of the study, participants entered a recovery phase. During this period, in which they were completed only 53 minutes of exercise, their body is largely returned to normal, but the mitochondrial function remained at 25% less than it was the second week of the study.

Although the study is relatively small and the long-term effects of hardcore exercises are unclear, researchers conclude: "HIIT exercise should not be excessive if an increase in health is a desired result" Mikael Flockhart, a researcher and a doctorate at the Swedish School of Sport and Health School, explained toThe New York Times.

According to the Mayo Clinic, you should have about 150 minutes of moderate exercise or 75 minutes of strong exercise every week. If you are a vigorous exerciser, this new study shows the benefits of reaching 90 minutes a week. If you are going as high as 152 minutes, you could do more harm than good.
