摘要
目的:研究宁夏汉族大学生指长波动性不对称(FA)与握力(HGS)的关系。方法:采用体质测量法,比较宁夏汉族大学生630例(男性232例,女性398例)示指、中指、环指、小指指长FA(2FA、3FA、4FA、5FA)、复合FA(CFA)及握力均值的差异性,分析2FA、4FA与握力的关系。结果:宁夏汉族大学生女性各指FA及握力均值低于男性,且2FA、4FA、CFA及握力差异有统计学意义;女性2FA和4FA人数在|L-R|≥0.04组显著低于男性;女性2FA和男性4FA与右手握力明显相关。结论:指长FA及握力有性别差异,2FA和4FA与握力相关,可能是个体某些运动潜能的间接生物学参考指标之一。
Objective： To investigate the relationship between fluctuating asymmetry （FA） of digit length and handgrip strength （HGS） in college students of Han ethnicity from Ningxia. Methods： Using anthropometry, the mean values of 2FA, 3FA, 4FA, 5FA, composite FA （CFA） and HGS of 630 （males： 232; females： 398） college students of Han ethnicity were compared, and the relationship between 2FA, 4FA and HGS were studied. Results： FA of each digit and HGS were lower in females than those in males. Significant differences of 2FA, 4FA, CFA and HGS were found between different genders. Compared with males, the distribution of 2FA and 4FA in I L--RI〉~0. 04 group were lower in females. 2FA significantly correlated with HGS in females while 4FA significantly correlated with HGS in males on the right hand. Conclusion; FA and HGS have gender difference. The 2FA and 4FA are correlated with HGS, which may be one of the indirect reference biomarkers for some potential exercise.
