Pumping it can pump the brakes in cognitive deterioration.
Alzheimer’s cases are expected to almost double by 2050, reaching the amazing 13 million cases. And although genetics certainly comes into play, there are some lifestyle factors that can increase, or reduce, their risk.
Now, researchers in Brazil have identified a change that older people can do only twice a week to protect against HYA.
Researchers at the State University of Campinas (UNICAMP) in São Paulo studied 44 elderly participants with mild cognitive impairment, a condition that indicates a high risk of dementia.
Posted in the magazine GeroscienceThe team discovered that strength training not only improved cognitive function but also changed the anatomy of the brain itself.
The participants were divided into two groups; The first participated in training sessions with high intensity weights twice a week, and the second group did not exercise in the entire study period.
After six months, weight training participants showed a better memory withdrawal and the quality of neurons, or the integrity of white matter.
In addition, the areas of the brain related to Alzheimer’s disease, the hippocampus and the Precuneus, were protected from atrophy.
Meanwhile, sedentary participants showed a worsening of brain parameters.
“In the group that did strength training, the right side of the hippocampus and the Precuneus were protected from atrophy.”

“We already knew that it would be a physical improvement. It also imagined a cognitive improvement, but we wanted to see the effect of weight training on the brains of the elderly with mild cognitive disabilities,” said the Isadora’s Ribipanhip or a fapepepptoral a fapepepptoral sciences (FCM) and the first author of the article.
“The study showed that, fortunately, weight training is a strong ally against dementia, even for people who already have a high risk of developing it.”
The benefits of weight training are well established: admits and builds muscle MTEA, relieves the symptoms of menopause and reduces the risk of a wide range of medical disorders, including cardiovascular diseases and diabetes, by improving the brain’s ability to access and process glucose.
Experts agree that adults should point for 150 minutes of physical activity of moderate intensity and two days of muscle strengthening per week for general health.
A 2024 study found that people who participated in moderate to vigorous activity (exercise that increases their pulse and breathing for a minimum of 10 minutes) had more brain mass in multiple regions, such as the hippocampus, why it is responsible for memory; Gray matter, which helps process information; And the occipital, frontal and parietal lobes.
“A characteristic of people with mild cognitive impairment is that they have loss of volume in some brain regions associated with the development of Alzheimer’s,” Ribeiro said.
“However, in the group that did strength training, the right side of the hippocampus and the Precuneus were protected from atrophy. This result justifies the importance of regular weight training, especially for older people.”
Agree for the team, weight training provides a two -pointed approach to fight dementia. It stimulates the production of the neural growth factor, which promotes and supports healthy neurons), and reduces inflammation in the body.
“It is known that any physical exercise, whether weight training or aerobic activity, increases the levels of a chemical involved in the growth of brain cells. It can also mobilize anti -inflammatory T cells. This is Balhazar key.
“After all, the more pro -inflammatory protein that is released in the body, the elderly the possibility of developing dementia, accelerating the neurodegenerative process and forming dysfunctional proteins that possible kill neurons.”
Even more promising is the hypothesis of the team that the most widespread periods of strength training could result in equally more significant, both physical and mental profits.
Ribeiro points out that, although all bodybuilding participants showed an improvement in the function of cerebral memory and anatomy, five participants reversed their diagnosis of mild cognitive deterioration.
“This leads us to imagine that the longest training sessions, which last three years, could make this diagnosis or delay any type of dementia progression. It is certainly something to have hopes and something you need.”
Researchers expect these findings to encourage patients and suppliers to explore effective, accessible and non -pharmacological measures, accessible and non -pharmacological to prevent dementia and improve mild cognitive deterioration.
