| 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。

| Abstract: | 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. |
