Exercise Prevents Dementia: Research

Regular physical exercise not only improves physical fitness, but also has a positive impact on brain metabolism, according to the researchers. The results showed that physical activity prevented an increase in choline – an important macronutrient for liver function, normal brain development, nerve function, muscle movements, supporting energy levels and maintaining energy. a healthy metabolism.

The concentration of this metabolite often increases due to the increased loss of nerve cells, which usually occurs in Alzheimer’s disease, said Johannes Pantel, professor at Goethe University in Frankfurt in Germany. In the study, physical exercise led to stable brain choline concentrations in the training group, while choline levels increased in the control group. The physical condition of the participants also improved and they showed increased heart efficiency after the training period.

Overall, these results suggest that physical exercise not only improves fitness, but also protects cells. To understand the positive influence of physical activity on the brain, gerontologists and sports physicians examined the effects of regular exercise on brain metabolism and memory of participants aged 65 to 85 on related parameters to movement, cardiopulmonary form and cognitive performance.

Participants were asked to ride an exercise bike three times a week over a 12-week period for 30-minute workouts. Magnetic resonance tomography (MRT) and magnetic resonance spectroscopy (MRS) have been used to measure the metabolism and structure of the brain. The results showed that regular physical exercise appears to be beneficial in preventing cognitive impairment and dementia in the elderly.
