摘要
目的:分析大学生步行量与体质的关系,建立大学生步行量参考标准;方法:使用计步器调查302名大学生1周的步行量,并进行体质健康测试,采用Person相关法分析步行量与各项体质指标的相关性,采用ROC曲线法建立大学生健康步行量参考标准;结果:大学生步行量与BMI、台阶指数、肺活量体重指数及体质健康测试总分之间有低度相关性,采用ROC曲线法可建立台阶指数及格、肺活量体重指数及格和体质健康测试及格所对应的步行量切点;结论:11 000步/天可作为大学生步行量参考标准。
Objective： To analyze the relationship of step-count per day and physical fitness of college students and develop daily step-count reference standard of college students. Methods： 302 college students＇ step-count of 7 consecutive days were monitored by pedometers, their physical fitness were also tested, the relationship between daily step-count and physical fitness was analyzed using Person correlation analysis, daily step-count references standard of college students were developed using Receiver operating characteristic （ROC） curve analysis. Results： Step-count was lightly correlated with BMI, step test index, vital capacity/weight index and fitness test score. ROC curve analysis can develop the step-count cut-points to reach the criterion of step test, vital capacity test and fitness test. Conclusion： 11, 000steps/day can be used as the daily step-count reference standard of college students.
