摘要
目的:探讨腰臀比(WHR)与人体反应速度的相关性。方法:收集8 630例健康体检者的体检资料,对WHR和反应时进行相关性检验和线性回归分析。结果:成年男性与女性的WHR分别为0.89±0.05、0.87±0.05;反应时分别为(0.45±0.05)、(0.46±0.05)s;无论男女,WHR与反应时均具有相关性(分别r=0.071、1.003,均P<0.05)。对于WHR升高的男性和女性,反应速度与WHR的直线回归方程分别为Y=0.380 7+0.075x、Y=0.320 9+0.156 9x。结论:WHR与反应速度具有一定相关性。男女WHR每升高0.1,反应时分别会增加0.007 5 s、0.015 7 s;WHR升高会导致身体素质下降,须预防WHR升高。
Objective： To explore the relationgship of waist-to-hip ratio （WHR） and human reaction speed. Methods： Eight thousand six hundred thirty cases of healthy information were collected, correlation test and linear regression analysis of WHR and reaction time were made. Results： Adult male and female WHR were 0.89 ± 0.05, 0.87 ±0.05 respectively ; reaction time was （0.45 ± 0.05 ） seconds, （0.46 - 0.05 ） seconds respectively. No matter men or women, WHR and reaction time correlated significantly （ r = 0.071, r = 1. 003, P 〈 0. 05 ）. The men and women who WHR elevated linear regression equation of reaction speed and WHR was Y = 0. 380 7 ＋ 0. 075x, Y = 0. 320 9 ＋ 0. 156 9x respectively. Conclusion： WHR is related to reaction speed. For men or women, WHR increasing 0.1, reacting time will increase O. 007 5 seconds, 0. 015 7 seconds. WHR elevating will lead to physical decline, which should be prevented.
