Physical activity and physical self-concept among sedentary adolescent females: An intervention study

Abstract

PROBLEM: Physical activity has been promoted as a means of enhancing self-concept, yet the evidence for this connection is far from compelling. In particular, experimental research investigating this association during adolescence, a period during which many youth struggle to maintain a positive self-image, is noticeably lacking. This study investigates the impact on self-concept of a 9-month physical activity intervention among sedentary adolescent females. METHOD: Female adolescents who were sedentary at baseline were assigned either to an exercise intervention or a comparison group as part of the controlled trial. The intervention was school-based, and assignment to groups was based on school attended. Intervention participants engaged in supervised activity 4 times per week and received didactic instruction promoting activity outside of school 1 day per week. Self-concept, physical activity participation, and cardiovascular fitness were assessed before, mid-way through, and after the 9-month intervention. RESULTS: The intervention had a significant positive impact on participation in vigorous activity and cardiovascular fitness. The intervention did not significantly influence any of the self-concept dimensions overall. There was, however, a three-way interaction such that there was an increase in global physical self-concept among those intervention participants who increased cardiovascular fitness. CONCLUSIONS: These findings indicate that a physical activity intervention among sedentary adolescent females enhanced global physical self-concept for a subset of intervention participants who manifested positive changes in fitness.

A Comparison of Physical Self-Concept between Physical Education and Non- Physical Education University Students

“…Several researchers have documented that athlete have higher self-concept as compared to non-athlete [26,29,[30][31]. Self-selection may be the main cause of these differences.…”

“…In the similar study Hays et al (17) also found same results. Schneider et al (35) in a study were examined the effect of physical activity on physical self-concept. Participants were required to meet the insufficient physical activity to maintain fitness, and ability to exercise.…”

Effects of Pilates-Based Exercise on Life Satisfaction, Physical Self-Concept and Health Status in Adult Women

“…While current literature supports physical exercise as a means to promote life satisfaction (Rejeski & Mihalko, 2001), physical self-concept (Faria & Silva, 2000;Schneider, Dunton, & Cooper, 2008), and perception of one's health status (Greenspan et al, 2007), few studies have focused on the relationship between mind-body exercise programs and these outcomes in healthy females.…”
