CORRELATION BETWEEN PHYSICAL ACTIVITY AND COGNITIVE FUNCTION IN YOUNG ADULTS

Background: The increasing prevalence of sedentary lifestyles among young adults has raised concerns about its potential impact on cognitive performance. Physical activity is known to influence brain health through physiological, biochemical, and psychological mechanisms. Objective: This study aims to evaluate the correlation between physical activity levels and cognitive function in young adults aged 18–25 years. Methods: A cross-sectional study was conducted among 250 university students. Physical activity was assessed using the International Physical Activity Questionnaire (IPAQ), and cognitive function was evaluated through standardized neuropsychological tests, including the Trail Making Test (TMT), Stroop Test, and Digit Span Test. Pearson's correlation and multiple regression analysis were used to assess the association between physical activity and cognitive parameters. Results: A significant positive correlation was found between moderate-to-vigorous physical activity and cognitive function scores, particularly in attention (r=0.34, p<0.01) and working memory (r=0.28, p<0.01). Students engaging in regular physical activity (>150 min/week) demonstrated significantly better cognitive test performance compared to sedentary peers (p<0.05). Conclusion: Higher levels of physical activity are associated with improved cognitive performance in young adults. Promoting active lifestyles in this age group may enhance mental efficiency, academic success, and long-term brain health.
