采用问卷调查、数理统计等方式,探讨家庭支持与青少年体育锻炼行为的关系,望从家庭角度诠释如何促进青少年体育锻炼行为提升,望为促进青少年健康提供理论依据。研究结果：男生参与体育锻炼频次（EF）为（2.61±1.14）、每次运动时间时间（TEE）为（3.09±1.47）分钟/次,运动强度（EI）为（2.67±1.32）,女生参与体育锻炼频次（EF）为（2.93±0.94）、每次运动时间时间（TEE）为（2.48±1.17）分钟/次,运动强度（EI）为（2.05±1.17）,男女生参与体育锻炼频次得分（t=-5.549,p<0.001）;运动强度得分（t=8.939,p<0.001）,每次运动时间（t=8.622,p<0.001）具有统计学意义。多元回归显示MPPA显著正向促进青少年参与体育锻炼EI和EF,FMTPFA显著正向改善青少年体育锻炼的EI,MMTPFA显著改善青少年参与体育锻炼的EF,MPFPA显著改善青少年体育锻炼EI,MPATPET显著改善青少年体育锻炼EF。结论家庭支持在不同程度改善青少年体育锻炼参与频次、每次时间和锻炼强度,父母参与体育锻炼、支持、监督、提供场地等能提升青少年参与体育锻炼的积极性（频次）、锻炼强度和运动时间,尤其是母亲在对青少年体育锻炼影响后中起到的作用更为明显。
