The influence of U.S. Army Basic Initial Entry Training on the maximum voluntary isometric strength (MVIS) and anthropometric parameters of men and women was investigated. Significant increases in weight and lean body mass (LBM) and decreases in percent body fat were found for both sexes during training. Significant increases in the MVIS of the upper torso (UT), leg extensors (LE), and trunk extensors (TE) were also found for both sexes. Females and males improved about the same amount on the LE (12.4% and 9.7%, respectively) but females improved significantly more than males on the UT (9.3% and 4.2%, respectively) and TE (15.9% and 8.1%, respectively). The greater gains in the females were presumably due to their lower initial strength levels and the consequently greater relative training stimulus. When strength was expressed relative to LBM, both sexes were able to exert similar amounts of strength on the LE and TE, suggesting that differences in strength between the sexes may primarily be a function of muscle mass.
研究了美国陆军基础新兵训练对男性和女性最大随意等长肌力（MVIS）及人体测量参数的影响。训练期间，男女的体重和去脂体重（LBM）均显著增加，体脂百分比均显著降低。男女上半身（UT）、腿部伸肌（LE）和躯干伸肌（TE）的MVIS也均显著增加。女性和男性在LE上的改善幅度大致相同（分别为12.4%和9.7%），但女性在UT（分别为9.3%和4.2%）和TE（分别为15.9%和8.1%）上的改善幅度显著高于男性。女性更大的进步可能归因于她们较低的初始力量水平以及由此产生的更大的相对训练刺激。当力量相对于LBM表示时，男女在LE和TE上能够发挥相似的力量，这表明男女之间的力量差异可能主要是肌肉量的函数。
