Exercising regularly not only enhances but may also boost metabolism, preventing impairment and in old age, a study has found.

Numerous studies have shown that seems beneficial in the prevention of impairment and in old age.

In order to find more about the positive influence of physical activity on the brain, researchers at Goethe University Frankfurt in have examined the effects of regular on metabolism and memory of 60 participants aged between 65 and 85.

They found regular not only enhances but also has a positive impact on metabolism.

Researchers thoroughly examined all the participants by assessing movement-related parameters, and performance.

In addition, magnetic resonance tomography (MRT) and magnetic resonance spectroscopy (MRS) were used to measure and brain structure.

Following this examination, the participants mounted an exercise bike three times a week over a period of 12 weeks.

The 30-minute training sessions were individually adapted to each participant's performance level.

The participants were examined again after the end of the programme in order to document the effects of this physical activity on brain metabolism, cognitive performance and brain structure.

The researchers also investigated to what extent exercise had led to an improvement in the participants'

As expected, physical activity had influenced brain metabolism: it prevented an increase in choline.

The concentration of this metabolite often rises as a result of the increased loss of nerve cells, which typically occurs in the case of Alzheimer's disease.

led to stable cerebral choline concentrations in the training group, whereas choline levels increased in the control group.

The participants' also improved: they showed increased cardiac efficiency after the training period. Overall, these findings suggest that physical exercise not only improves physical fitness but also protects cells.

The research was published in the journal Translational Psychiatry.
