学生是祖国的未来，他们的身体素质在一定程度上决定着国民素质，直接关系国家未来的发展。学校以及政府为了提高学生的体质健康水平，做出了很多努力，而想要达到目的，必须要有学生家长的共同努力。首先，该研究采用问卷调查法了解中学生的家庭体育活动情况以及对于中学生体质健康水平的影响因素。其次，根据研究对象的体质健康测试结果分为第①组和第②组，第①组的成绩较第②组更为优秀。最后，采用数理统计法分析两组的家庭体育活动情况，主要结论如下： 家庭成员的体育与健康知识掌握程度能直接影响到中学生的体质健康水平，体育与健康知识掌握更全面的家长其孩子的体质健康水平一般较好。 中学生的家庭体育活动中运动的项目越丰富、趣味性越高，那么对于提高其体质健康水平的帮助越大。且家长在选择开展家庭体育活动的方式中，以中学生能够直接参与到体育锻炼的方式为最佳。 中学生家庭体育活动的开展次数及时长能够直接影响到中学生的体质健康水平，以开展次数越多且时长在一个小时左右为最佳。 中学生在进行家庭体育活动过程中经常去的体育场所越多，那么其体质健康水平一般较好。家长对于孩子的体育锻炼重视程度对其体质健康水平也有很大的影响，体质健康水平较差的大部分家长会更愿意支持孩子在提高学业成绩上的花费，对于家庭体育活动中的花费却不是那么肯定。
