Brain health may depend on leg power of older women

A decade long study has found that a fit brain in ageing ladies could be result of maintaining powerful legs. Experts advise that the power of legs can be a helpful maker that a person is getting sufficient exercise to maintain a fit mind.

The findings come from the analysis of 325 twins by a team from the London King College. The study presents that exercise permits the body to release chemicals that could better elderly brains.

In the study, released in the Gerontology journal, more than 151 pairs of twin sisters aged 43 to 73 were watched for their health over ten years.  Results presents that those who have powerful legs at the starting of the study maintained a perfect cognition even after a decade, with few replacements in brain attached with ageing.

The participants also maintained a best brain condition even when experts included other health and lifestyle risk factors for dementia for the analysis.

When it came to cognitive ageing, leg power was the powerful factor that had an impact in our study,” Dr Claire Steves (lead researcher), senior lecturer in King London College and King London Hospital on Twin Research.

For the study, experts measured the leg force of participants, including power and speed of leg extension, using modified gym tool. Brain power was analysed via computerised jobs, which tested the participants mental and memory processing skills.

Experts noted that there could be other lifestyle reasons that potentially support leg power to better brain health. “Other reasons such as heart health were also vital, but the link with leg power remained even after we accounted for these,” Claire said.

The study reports the rising proof that physical activity could significantly support the body and the brain, according to Dr Doug Brown, Alzheimer society director of research. Anyway, researchers said that more studies are required to perfect understand the link between health measures like brain and leg changes, and to see the unique cause-and-effect of body activity on brain cognition and structure.

“Anyway, we still don’t completely understand how this link works and how we can increase the advantage,” he said.

“And we have yet to see if the advancements in memory tests exactly translate into a reduced danger of dementia.”
