2、4.27)cm、体重(52.96~3.28)kg;男生7名,年龄(20.25~0.71)岁,身~(173.64~4.64)cm,体重(66.57~4.60)。隔日测量RE,测试时间和测量顺序均一致,室内气温20℃,湿度45%,结果发现,RE隔日测量结果配对f检验差异没有显著性,相关性呈高度相关;组内相关系数ICC结果较高,Bland.Altman图形中2次RE测量结果差值的分布服从正态分布,所有的差值数据均在95%的一致性界限以内。结果表明,RE隔日测量可靠性比较高,但是,影响RE的因素非常复杂,在实际测量的过程中,要始终保证受试者在前后测量身体处于非疲劳状态,测试前两天
3、保证受试者进行30min以上的熟悉跑台跑步,前后两次测试顺序和测试时间尽量保持一致。关键词:运动生理学;跑步经济性;重测信度中图分类号:G804.7文献标志码:A文章编号:1006.7116(2014)04—0125.05EvaluatingthereliabilityofeveryotherdayrunningeconomymeasurementquantitativelybyusingdifferentmethodsWANGZhi-ming(DepartmentofTrackandField,GuangzhouSponUniversity,Guangzhou51050
