目的 探讨高水平背肌力者的Heath-Carter法体型分类。 方法 对某全训部队418名男战士，按GJB1337-92规定测量背肌力；按国际通用的Heath-Carter体型方法测量体型并分类。 结果 418名男战士背肌力均值为（134.3±22.6）kg，总体评价为良好。背肌力良好以上者270人，占64.7%，均值为（147.0±16.7）kg，体型均值为2.4（0.8）-5.0（1.2）-2.3（0.9），体型位置均值（SAM）为1.5，良好以上者中有237人体型集中于中胚层体型，占87.8%。内、中、外3因子是影响背肌力成绩的主要因素，背肌力成绩越好，内、外因子值越小，而中因子值越大。 结论 高水平背肌力者的体型分类高度集中于中胚层体型。背肌力与中因子值成显著正相关。

Objective To explore the somatotype classification of high level dorsal muscle strength. Methods Dorsal muscle strength of a complete training unit of 418 male soldiers, according to the provisions of GJB1337-92 were measured and classified the somatotype by the method of Heath-Carter. Results The mean value of dorsal muscle strength of the 418 male soldiers was (134.3±22.6) kg, overall evaluation was good. Dorsal muscle strength good and above was 270, accounting for 64.7%; the mean value was (147.0±16.7) kg, the mean value of somatotype was 2.4(0.8)-5.0(1.2)-2.3(0.9), somatotype attitudinal mean（SAM）was 1.5, 87.8% focused on the medium of embryo type. The factors of endomorphy, mesomorphy and ectomorphy were the main factors that affected the dorsal muscle strength score. The better of the dorsal muscle strength score, the lower value of the endomorphy and ectomorphy factors, the higher value of the mesomorphy factor. Conclusion The high level of dorsal muscle strength in the somatotype classification is highly concentrated in the medium of the embryo type. Dorsal muscle strength is significantly positively correlated with the mesomorphy value.
