Doing physical exercise between 45 and 65 can be beneficial to prevent the development of Alzheimer’s, while sedentary habits would be harmful to brain healthaccording to a study.
The investigation, which have led the Global Health Institute of Barcelona (ISGlobal) -Centro promoted by the “La Caixa” Foundation – and Barcelonaβeta Brain Research Center (BBRC) of the Pasqual Maragall Foundation, has been published in the scientific journal Alzheimer’s & Dementia.

Beta amyloid protein
The study links the level of physical activity of people with the accumulation of beta amyloid protein, the isglobal has reported in a statement.
Beta amyloid is a protein that can hinder communication between neurons if it accumulates in the brain and is a key factor in the subsequent appearance of symptoms of this neurodegenerative disease.
Monitoring for four years
Scientists have followed up for four years of 337 middle -aged people (from 45 to 65 years old) with a family history of Alzheimer’s.
In this period it has been evaluated your physical activity level And neuroimaging tests, explained the first author of the study, Müge Akıncı, doctoral researcher in Isglobal and BBRC at the time the investigation was carried out.

What the study shows
The study has shown that the participants who followed the recommendations of physical activity determined by the World Health Organization (WHO) presented a lower accumulation of beta amyloid with respect to those who reduced their physical activity or adopted a sedentary lifestyle.
Specifically, WHO recommends doing between 150 and 300 minutes of moderate physical exercise or between 75 and 150 intense minutes per week.
In addition, study scientists have detected that, the greater the increase in activity, the greater the reduction of the presence of this protein in the brain.
More cortical thickness in non -sedentary subjects
Non -sedentary subjects have also turned out to have a higher cortical thickness in some regions of the brain related to the Alzheimer’slike medial temporal areas, keys in memory.
According to the ISGlobal, it is estimated that 13% of Alzheimer’s cases can be attributed to physical inactivity.
In this sense, the Isglobal researcher who has led the study, Eider Arenaza-urquijo, has expressed that the results “reinforce the importance of promoting exercise in medium age as a public health strategy” and that these campaigns “could be key to reducing the incidence of Alzheimer’s in the future.”
