Children’s and Adolescents’ Physical Self-Perceptions as Related to Moderate to Vigorous Physical Activity and Physical Fitness

The aim of this study was to determine the relationship between physical self-perceptions, moderate to vigorous physical activity and physical fitness in Estonian school children and adolescents aged 11–14 years. The sample consisted of 134 boys and 119 girls. Self-perception of body appearance, physical conditioning, sport/athletic competence, strength and general physical self-worth were measured by the Children’s Physical Self-Perception Profile (C-PSPP). Moderate to vigorous physical activity was assessed using 7-day physical activity recall and physical fitness using 20 meter endurance shuttle run. All C-PSPP scales were significantly moderately related with physical activity and fitness in both boys and girls. Boys’ perceptions of strenght competence, physical condition and general self-worth were higher and they participated more in moderate to vigorous activities compared to girls. Multiple regression analysis results indicated the best predictors of moderate to vigorous physical activity and physical fitness were perceived sport/athletic competence, physical self-worth, and perceived strength competence Our results demonstrate that physical self-perceptions are significant correlates of physical activity and fitness in children and adolescents.
