Previous studies that examined participation in physical activity suggested that female adolescents were less active compared with males. However, the relationship between physical fitness, physical activity participation, and perceived benefits and barriers for physical activity to adolescents, irrespective of gender, has not been made clear. This study examines the association of these factors in female adolescents.
Physical activity participation and perceived benefits and barriers to physical activity were determined in 206 secondary school female subjects (aged 11 to 18) using a validated questionnaire.
Subjects with a correct concept about optimal physical activity participation to maintain health engaged in an activity level higher than the group without a correct concept (t=2.37, p=0.02). A significant correlation was established between the physical activity participation with "health" (r=0.22, p<0.001) and "body image" (r=0.17, p=0.02) in the perceived benefit category. The individual factor, "make me feel better in general" in the "health" category (p=0.04) and the intention to participate (p<0.001) were shown to be significant predictors for physical activity participation. The combined effects of the regression model explained 35.9% of the variance in participation in physical activity.
Policies to support regular physical activity participation at school and out-of-school should be strategically developed and promoted, highlighting the promotion of health benefits in exercise and the reinforcement of initial intent towards exercise.
先前有关参与体育活动的研究表明，与男性相比，女性青少年的活动量较少。然而，青少年的体能、体育活动参与情况以及对体育活动的感知益处和障碍之间的关系，无论性别如何，都尚未明确。本研究探讨了这些因素在女性青少年中的关联。
使用经过验证的问卷，对206名中学女生（年龄在11至18岁之间）的体育活动参与情况以及对体育活动的感知益处和障碍进行了测定。
对维持健康的最佳体育活动参与有正确概念的受试者，其活动水平高于没有正确概念的组（t = 2.37，p = 0.02）。在感知益处类别中，体育活动参与与“健康”（r = 0.22，p < 0.001）和“身体形象”（r = 0.17，p = 0.02）之间建立了显著相关性。“健康”类别中的个体因素“总体上让我感觉更好”（p = 0.04）和参与意愿（p < 0.001）被证明是体育活动参与的重要预测因素。回归模型的综合效应解释了体育活动参与差异的35.9%。
应从战略上制定和推广支持在校内外定期参与体育活动的政策，强调运动对健康的益处以及强化最初的运动意愿。
