摘要
目的:探讨速度指标成绩优良者的Heath-Carter法体型分类。方法:对某部队418名男战士,按GJB1337-92原则和规定,进行百米跑成绩的测定;按GJB1102-91规定测定瘦体质量百分率(LBW%);采用国际通用的Heath-Carter法测量体型。结果:23名百米跑成绩优秀者中有22名的体型集中于中胚层体型,占95.7%;124名百米跑成绩优良(含优秀)者中有114名的体型集中于中胚层体型,占91.9%;LBW%达标者百米跑成绩为14.21s±1.03s,LBW%非达标者百米跑成绩为14.62s±1.02s,两者比较差异存在统计学意义。内、中、外3因子是影响百米跑成绩的主要因素,百米跑成绩用时越短,内、外因子值越小,而中因子值越大。结论:百米跑成绩优良者的体型分类高度集中于中胚层体型。百米跑成绩即用时时间与中因子值呈负相关。
Objective:To explore the somatotype classification of people with excellent speed grades.Methods:100-meter race results of 418 male soldiers were measured according to the provisions of GJB1337-92.The percentage of lean body weight(LBW%)of those male soldiers was calculated according to the provisions of GJB1102-92 and the somatotype was determined by the method of Heath-Carter.Results:Among the 23 people who were excellent in 100-meter race,22 people had the mesomorphy,accounting for 95.7%.The number of good(including excellent)was 124,114 people had the mesomorphy,accounting for 91.9%.The result of LBW% was 14.21 s±1.03 s,that of non-standard score of LBW% was 14.62 s±1.02 s.and the difference was significant.The factors of endomorphy,mesomorphy and ectomorphy were the main factors that affected the results of 100-meter race.The better of the results,the lower value of the endomorphy and ectomorphy factors,the higher value of the mesomorphy factor.Conclusion:The somatotype of people with excellent grades in 100-meter rale is highly concentrated in the mesomorphy.The result of 100-meter race is significantly negatively correlated with the mesomorphy value.
