놀이중심 신체활동이 아동의 스트레스 호르몬과 작업기억력에 미치는 영향 = The Effects of Play-Centered Physical Activity on Stress Hormones and Working Memory in Children

다국어 초록 (Multilingual Abstract)

This study examined the effects of a 12-week play-centered physical activity program on stress hormone levels and working memory in children. Twenty-two male students were randomly assigned to an exercise group and a control group. The program, conducted three times per week for 40 minutes, was designed to promote enjoyment, active participation, and continuous engagement through flexible play activities. Cortisol levels and working memory were measured before, during, and after the intervention using biochemical and cognitive assessments. The results indicated that the exercise group showed reduced cortisol levels and improved working memory compared to the control group. These findings suggest that play-centered physical activity contributes to stress regulation and cognitive enhancement in children, emphasizing its educational value for supporting emotional stability and cognitive development.
