| Family sports environment,as a medium to carry teenagers’ physical activities,master sports skills and cultivate the spirit of hard work,refers to the three-dimensional space of physical,behavioral and psychological interaction that family members receive in the process of participating in physical exercise.As a carrier for teenagers to participate in physical exercise and receive physical education,it plays an internal driving role in promoting the socialization,healthy and integrated development of teenagers.By studying the interrelationship between family sports environment and teenagers’ willingness to participate in physical exercise,we can clarify the strength and direction of the impact of family sports environment and other dimensions and indicators on teenagers’ participation in physical exercise,and clarify the impact mechanism between the two,so as to improve the family sports environment,gradually increase the participation rate of teenagers’ after-school physical exercise,and further promote the family The integrated development of school and community sports has important practical significance.This study adopts the methods of literature,questionnaire,interview and mathematical statistics,takes parents and teenagers as the subjects,and uses the theory of planned behavior as the theoretical basis.On the basis of combing the relevant literature and measuring tools of domestic and foreign family sports environment and adolescents’ willingness to exercise,and combining with the actual situation of China,the "Family Physical Environment Questionnaire","Family Sports Behavioral Environment Questionnaire","Family Sports Psychological Environment Questionnaire" and "Youth’s willingness to exercise Questionnaire" were prepared,and the preliminary questionnaire was revised through expert evaluation and objective test.Then,the dimensions of each questionnaire were determined by exploratory factor analysis,and the

analysis,the image relationship between family sports environment and teenagers’ willingness to exercise was clarified,and the strong correlation factors affecting teenagers’ willingness to exercise were found.Finally,according to the research results,the optimization strategy of family sports environment is proposed.Through research,the main conclusions are as follows:(1)The physical environment of family sports is a four-dimensional structural model,including four dimensions: indoor equipment support,outdoor field supply,electronic product use,and electronic equipment restriction.The cumulative explained percentage of variance is 66.90%,more than 60%,and the reliability and validity indicators of the questionnaire meet the measurement requirements.(2)The family sports behavior environment is a six-dimensional structural model,including six dimensions: outdoor sports restriction,indoor sports restriction,physical activity control,parental sports encouragement,parental sports support and parental sports participation.The cumulative explained percentage of variance is 67.25%,more than 60%,and the questionnaire reliability and validity indicators meet the measurement requirements.(3)The family sports psychological environment is a five-dimensional structural model,including five dimensions: ability expectation,sports difficulty,demand effort,psychological frustration and sports value.The cumulative explained variance percentage is 69.91%,more than 60%,and the reliability and validity indicators of the questionnaire meet the measurement requirements.(4)Physical environment of family sports(β= 0.22,p<0.05),psychological environment(β= 0.255,p<0.05)and behavioral environment(β= 0.152,p<0.05)had a positive impact on the willingness of teenagers to exercise,and the impact of psychological environment and physical environment was significant.(5)The support of indoor equipment,the supply of outdoor field,the use of electronic
