Mitochondria in cells is responsible for converting food into energy, in particular burning calories and turning them into heat. Thus, the more muscles you have, the more mitochondria that will help to burn calories more efficiently.

However, according to the study, it is incorrect training technique that can negatively affect the efficiency of mitochondria, which recalls the importance of proper training to maintain optimal metabolism. What is said in the study and how intense training affects the body, they told Eat this, not that.

The study on an excessive HiIT training study showed that excessive intensity during training can negatively affect the body, in particular, insulin resistance and mitochondrial function. Thus, increasing the duration and intensity of training for several weeks without proper recovery can lead to a decrease in the effectiveness of metabolic processes. That is why, it is recommended to gradually increase the load and alternate the periods of intense training with restoration to achieve optimal results.

The influence of intensive training after 3 weeks of the experiment during the first two weeks of training, the experiment participants noticed the usual effects of high intensity, in particular, an improvement in mitochondrial function. However, in the third week, this function decreased by 40%, which was associated with violations of glucose tolerance and an increase in insulin resistance.

This indicates that excessive physical activity can negatively affect the metabolic function, even if you train regularly. In addition, it is important to balance the intensity of training in order to avoid negative effects (plateau) on the energy system.

Results after 4 weeks of training after such intense training, the body needs to restore. That is why during this period the participants performed minimal physical exertion lasting up to 53 minutes.

At the same time, although their bodies returned to a normal state, however, the function of the mitochondria remained 25% lower than during the second week of research.

Recommendations to improve health, do not overload yourself with intense training. It is enough to engage in physical exercises for 150 minutes a week of moderate intensity or 75 minutes of intensive training. However, if you are an active athlete, you can get a result in just 90 minutes. Keep in mind that this time excess can lead to negative health consequences.
