Purpose: For decades, researchers have proclaimed the positive psychosocial benefits of participation in physical activity. However, recent meta-analyses of the literature have found infrequent and inconclusive empirical support for the link between physical activity and psychosocial well-being. In this study, we use data from a longitudinal study to explore the links between participation in physical activity and global self-esteem among girls from childhood into early adolescence and the direction of this relationship.
Methods:Participants included 197 non-Hispanic white girls. Girls' participation in physical activity and their global self-esteem were assessed when they were 9, 11, and 13 years old. Panel regression was used to assess the lagged effect of physical activity on self-esteem and the lagged effect of self-esteem on physical activity, controlling for family socioeconomic status (SES) and girls' body mass index (BMI).Results: A significant lagged effect of physical activity on self-esteem was identified. Specifically, higher physical activity at ages 9 and 11 years predicted higher self-esteem at ages 11 and 13 years respectively, controlling for covariates. Positive effects of physical activity on self-esteem were most apparent at age 11 and for girls with higher BMI. No support was gained for the lagged effect of selfesteem on physical activity.
Conclusions:Results suggest that participating in physical activity can lead to positive self-esteem among adolescent girls, particularly for younger girls and those at greatest risk of overweight. These findings highlight the necessity of promoting physical activity among adolescent girls as a method of fostering positive self-worth.

NIH-PA Author ManuscriptThe positive effect of physical activity on mental health is a long-held and widely accepted belief among scholars and practitioners alike. Mental health benefits of physical activity may result from increases in social support and a sense of mastery as well as changes in noradrenaline and neurotransmitters such as dopamine and serotonin [1]. Recent reviews of the literature, however, indicate that empirical support for the link between participation in physical activity and psychosocial well-being is infrequent and inconclusive [2][3][4][5]. With this in mind, this study assesses the longitudinal association between physical activity and global self-esteem in a sample of adolescent girls, a population at risk for depression and low selfesteem [6][7][8].Self-esteem is the focus of this study because it has been identified as a predictor of many other constructs that constitute psychosocial well-being. Higher levels of self-esteem are associated with increased self-efficacy, body image, and leadership, and reduced levels of depression and anxiety [5,9]. As outlined in recent reviews [2,5,10], few studies have examined the link between physical activity and self-...
