Explore the correlation and predictive power of health physical fitness on health-promoting lifestyle of adolescents to provide an important reference for reform in middle school physical education classroom teaching. Taking some junior and senior high school students in Nanchong City of Sichuan Province as survey objects, a stratified random sampling method was used to carry out a health/fitness test and conduct a questionnaire survey. SPSS17.0, amos 21.0, and other statistical analysis software were used to process the relevant data. (1) Male adolescents had 14.4% predictive power for their overall health-promoting lifestyle through the combined effects of cardiopulmonary endurance, muscle strength, and explosive strength, while female adolescents had 16.8% predictive power for their overall health-promoting lifestyle through the combined effects of cardiopulmonary endurance, flexibility, and body mass index (BMI). (2) Ten percent of the variation in the health-promoting lifestyle of men under 14 years old was caused by the combined effects of muscle endurance and muscle strength, while 14.4% of the variation in the health-promoting lifestyle of female adolescents was caused by the combined effects of muscle endurance, muscle strength, flexibility, and cardiopulmonary endurance. (3) Some 10.9 and 17.6% of the variation in health-promoting lifestyle of male and female adolescents aged between 14 and 17 was caused by the combined effects of cardiopulmonary endurance, muscle strength, and flexibility, respectively. (4) Some 20.7% of the variation in health promoting lifestyle of male adolescents aged 17 years or above was caused by cardiopulmonary endurance, explosive force, and muscle endurance, while 16.8% of the variation in health-promoting lifestyle of female adolescents was caused by the combined effect of cardiopulmonary endurance, BMI, and muscle endurance. Health and physical fitness of adolescents can significantly predict their health-promoting lifestyle, and the predictive power and typical correlation between them are affected by demographic factors.
探讨青少年健康体适能与健康促进生活方式的相关性及其预测能力，为中学体育课堂教学改革提供重要参考。以四川省南充市部分初中和高中生为调查对象，采用分层随机抽样方法进行健康/体适能测试和问卷调查。采用 SPSS17.0、amos21.0 等统计分析软件对相关数据进行处理。（1）男生心肺耐力、肌肉力量和爆发力综合作用对整体健康促进生活方式的预测能力为 14.4%，女生心肺耐力、柔韧性和 BMI 综合作用对整体健康促进生活方式的预测能力为 16.8%。（2）14 岁以下男生健康促进生活方式的 10%变异是由肌肉耐力和肌肉力量的综合作用引起的，14 岁以上女生健康促进生活方式的 14.4%变异是由肌肉耐力、肌肉力量、柔韧性和心肺耐力的综合作用引起的。（3）14-17 岁男、女生健康促进生活方式的 10.9%和 17.6%的变异是由心肺耐力、肌肉力量和柔韧性的综合作用引起的。（4）17 岁及以上男生健康促进生活方式的 20.7%变异是由心肺耐力、爆发力和肌肉耐力引起的，而 17 岁及以上女生健康促进生活方式的 16.8%变异是由心肺耐力、BMI 和肌肉耐力的综合作用引起的。青少年的健康和体适能可以显著预测其健康促进生活方式，且两者之间的预测能力和典型相关性受到人口统计学因素的影响。
