Researchers at the University of Michigan have found that a protein, sestrina, has increased production during physical activity, which may be the protein responsible for the benefits of exercise, such as improving cardiorespiratory capacity, increasing physical endurance and burning fat.
Sesrine is a metabolism-regulating protein that occurs in metabolic stress situations, which occurs during exercise. In addition, sestrina is responsible for coordinating various biological activities, as it participates in several metabolic pathways and may be associated with the benefits of exercise.
- The study.
- Conducted by researchers at the University of Michigan in the United States.
- Was conducted with flies to test the production of sesthrin in these animals and the effect of this protein.
- To do this.
- They divided these animals into three main groups: one that was programmed to overexpress sestrination.
- Another that was programmed not to produce sestrination.
- And a third in which no changes were made.
For flies, researchers trained these insects for about 3 weeks and compared the amount of sesthrin obtained between the groups and between the type of related activity, such as flying and “running” on a treadmill created specifically for the fly.
Based on the results of the experiments, it could be verified that animals that did not exercise but had been modified to overexpress sesrin, actually had a higher concentration of this protein in circulation and that the effects produced by the protein were the same as those obtained through physical activity, in which sesthrin is naturally produced. In addition, they found that in the group, there was a change not to produce sestrin, although much exercise was done, there was no improvement in strength and flightability.
Thanks to the results, it has been confirmed that sestrina plays a fundamental role in promoting the benefits of physical activity, such as improved fitness, cardiorespiratory capacity and the ability to burn fats. However, it was also possible to verify that high amounts of sestrin in circulation are also linked to benefits even if the exercises are not carried out. For this reason, the researchers indicated that sesrin could replace physical activity, as this protein is associated with muscle mass gain and cardiorespiratory improvement.
Despite this, they also warned that this substitution would be justified for people who have restrictions on physical activity, such as the elderly and people in wheelchairs, because over time they lose strength and muscle mass. In addition, existing studies have been conducted only with flies and rats and therefore the result in humans may be different, as the metabolisms are different and it is important to conduct more studies.
Despite the discovery of sestrina as an important protein to ensure the benefits promoted by physical activity, even if activity is not practiced, more studies are needed, among other things because researchers have stated that the idea of using a sestrina supplement is still very long. Far. to achieve, in addition to the fact that the mechanism that leads to the production of sestrination as a result of the exercise is not yet known.
Therefore, to guarantee the benefits of physical activity, it is best to practice effectively, because it is possible to:
In addition, through physical activity, it is possible to prevent various diseases, as it promotes improved blood circulation, oxygenation of the brain and respiratory capacity. Discover other benefits of physical activity.
