Adolescence is a critical period for the acquisition of health-related behaviors that will transcend later psychological well-being in adulthood. The present study presents a theoretical model whose objective is to analyze how physical activity predicts an adequate quality of life through self-concept and subjective happiness among adolescents. A total of 452 students aged 12 to 15 (M = 13.8; SD = 0.77) from four Compulsory Secondary Education institutes of the Autonomous Community of Extremadura participated, including boys ( = 258) and girls ( = 194). The students reported information on the following variables: physical activity, body mass index, self-concept, subjective happiness, and quality of life. The results show acceptable fit indices for the proposed theoretical model, which showed the importance of physical activity through self-concept and subjective happiness in quality of life: MRLχ = 67.533, < 0.05, CFI = 0.93, TLI = 0.90, SRMR = 0.05, and RMSA = 0.07. Likewise, the model presented a better fit index for males than females. This study draws conclusions on the importance of physical activity as a predictor of quality of life mediated by the perception of self-concept and mood in adolescents.
青春期是获得与健康相关的行为的关键时期，这些行为将超越成年后 later psychological well-being。本研究提出了一个理论模型，旨在分析体育活动如何通过青少年的自我概念和主观幸福感来预测其生活质量。共有来自埃斯特雷马杜拉自治区的四所义务中等教育学院的 452 名 12 至 15 岁的学生（M = 13.8；SD = 0.77）参与了这项研究，其中包括男生（n = 258）和女生（n = 194）。学生报告了以下变量的信息：体育活动、体重指数、自我概念、主观幸福感和生活质量。结果显示，所提出的理论模型具有可接受的拟合指数，表明体育活动通过自我概念和主观幸福感对生活质量的重要性：MRLχ = 67.533，< 0.05，CFI = 0.93，TLI = 0.90，SRMR = 0.05，RMSA = 0.07。此外，该模型对男性的拟合指数优于女性。本研究得出结论，体育活动作为生活质量的预测指标，通过青少年对自我概念和情绪的感知，具有重要意义。
