Pump -It can pump the brakes in cognitive decrease.
Alzheimer’s cases are expected to be doubled by 2050, reaching an impressive 13 million cases. And although genetics certainly have some life factors that can increase or reduce your risk.
Brazil researchers have now pointed out a change that seniors can do twice a week to protect themselves from dementia.
Researchers at the State University of Campinas (Unicamp) in São Paulo studied 44 large participants with a mild cognitive decrease, a condition that indicates a higher risk of dementia.
Published in Geroscience Magazine, the 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 was dedicated to weighing training sessions of two to the intensity at high intensity and the second group did not exercise at all during the study period.
After six months, weight training participants showed an improved memory memory and the quality of the 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 the atrophy.
“In the group that performed strength, the right side of the hippocampus and the precunes were protected from the atrophy.”

Meanwhile, sedentary participants showed a worsening of the brain parameters.
“We already knew there would be physical improvement. We also imagined cognitive improvement, but we wanted to see the effect of weight training on the brain of the elderly with a mild cognitive impairment,” said Isadora Ribeiro, a doctoral scholarship receptor from FAPESP at the Unicamp School of Medical Sciences (FCM) and the first author of the article.
“The study showed that, luckily, weight training is a strong ally against dementia, even for people who already have a high risk of developing it.”
The advantages of weight training are well established: supports and builds muscleASS, facilitates symptoms of menopause and reduces the risk of a wide range of medical disorders, including cardiovascular disease and diabetes, improving the brain’s ability to access and process glucose.
Experts agree that adults must sign up for 150 minutes of moderate intensity physical activity and two days of muscle reinforcement a week for general health.
A 2024 study found that people who participated in a moderate activity in vigorous – exercising their dust speed and breathing for a minimum of 10 minutes – had more cerebral mass in various regions, such as the hippocampus, responsible for memory; Gray matter, which helps process information; and the occipital, frontal and parietal lobes.
“A feature of people with mild cognitive impairment is that they have volume loss in some brain regions associated with Alzheimer’s development,” said Ribeiro.
“However, in the group that strengthened, the right side of the hippocampus and the precunes were protected from the atrophy. This result justifies the importance of regular weight training, especially for the elderly.”
According to the team, weight training provides a two -point approach to fight dementia.
It stimulates the production of neural growth factor, which favors and supports healthy neurons) and reduces inflammation in the body.
“Any physical exercise, whether weighing or aerobic activity, is known for increasing the levels of a chemical involved in the growth of brain cells. It can also mobilize anti -inflammatory T cells. This is key,” said robust supervisor Marcio Balthazar.
“After all, the more proinflammatory protein is released into the body, the greater the ability to develop dementia, accelerating the neurodegenerative process and forming dysfunctional proteins that eventually kill neurons.”
Even more promising is the hypothesis of the team that the larger strength training periods could produce even more significant, both physical and mental gains.
Ribeiro states that while all bodybuilding participants showed an improvement in the function of memory and brain anatomy, five participants reversed their diagnosis of mild cognitive impairment.
“This leads us to imagine that the longest training sessions, which last three years, for example, could reverse this diagnosis or delay any type of progression of dementia. It is certainly something we expect and something to be studied in the future,” said Ribeiro.
Researchers hope these findings will encourage patients and suppliers to explore these effective, accessible and non -pharmacological measures to prevent dementia and improve mild cognitive deterioration.
