Weight Training May Protect the Brain from Dementia: New Scientific Study

A recent study revealed that resistance training (such as weight lifting) not only strengthens muscles and bones but may also play a crucial role in preserving brain function and preventing dementia.

 Study Details:

• Conducted by researchers at the University of Sydney (Australia), the study followed a group of older adults experiencing mild cognitive impairment (MCI) — a condition that often precedes dementia.

• Participants were divided into groups, with one group performing weight-based resistance training twice a week for six months.

• After follow-up, the weight-training group showed significant improvements in memory and executive brain functions, and a slower rate of brain shrinkage, compared to the group that didn’t exercise.

 Why Does Weight Training Help the Brain?

• These exercises increase blood flow to the brain, improving oxygen delivery.

• They stimulate the release of neurotrophic factors that support the growth of new brain cells.

• They reduce chronic inflammation, which contributes to neurodegenerative diseases like Alzheimer’s.

✅ Recommendations:

• Experts suggest doing resistance training at least twice a week, even with light weights, especially after the age of 50.

• Combining exercise with a healthy diet and good sleep can provide a comprehensive shield for brain health.
