Physical exercise triggers the release of brain-strengthening proteins

Physical exercise, even for a short period of time, can have an immediate and powerful impact on brain health. A new study has found that just 15 minutes of aerobic exercise is enough to increase levels of a key protein that helps brain function.

According to research published in the scientific journal Brain Research, physical activity stimulates the release of brain-derived neurotrophic factors (BDNF), a protein that supports the growth and maintenance of nerve cells.

The researchers also found that the fitter a person is, the more production of this protein increases after exercise. This means that the benefits for the brain increase with improved physical condition.

The study involved 30 unfit people who followed a 12-week program of cycling four times a week. Although baseline BDNF levels did not change significantly during rest, the brain's response to exercise significantly improved by the end of the program.

In the final weeks, participants showed greater increases in BDNF after physical activity, which was directly related to improvements in their aerobic capacity.

Furthermore, these increases were associated with positive changes in the prefrontal cortex, an area of ??the brain associated with decision-making, concentration, and self-control.

Experts say these findings shed more light on how exercise affects brain function and suggest that the benefits may appear sooner than previously thought.

In conclusion, even a short exercise session can be an effective way to improve mental health and cognitive functions, while regular physical activity strengthens these effects over time./ CNA
