Effects of physical activity on cognitive function according to the latest selected scientific studies

Abstract

Background: With the development of medicine, people's life expectancy is increasing, and consequently, there is interest in improving the quality of life, which is affected by, among other things, cognitive functions. Cognitive functions are represented by memory, the ability to absorb new information, speech, attention, reading comprehension, and communication. Many researchers have shown that physical activity (PA) can affect these processes. Aim of the study:The study aims to review the latest scientific studies on the effects of PA on cognitive functions in the broadest sense, specifically on the memory and attention of people of different ages. The paper also explains some of the processes that occur during PA and their impact on cognitive function.Material and methods:A literature review of recent scientific studies in Google Scholar, PubMed, and National Library of Medicine databases published from 2016 to 2024. The inclusion criteria were that the article had a thorough research methodology, publication language English or Polish, and open access.State of knowledge: PA, thanks in part to its effect on the release of beta-endorphins during exercise, promotes neurogenesis in adults and improves broader brain health. PA also improves brain function by affecting astrocytes - the star cells that maintain brain homeostasis. Researchers have shown that acute PA improves attention, while regular PA, lasting at least several weeks, improves academic performance. Studying adults, it has been observed that regular PA can slow progressive cognitive impairment during aging. In studies involving children, PA has been shown to have a positive effect on attention and learning.Conclusions: PA has a positive effect on improving cognitive function in people of all ages, both healthy and those with already established cognitive impairment. More research is needed.
