The purpose of this study was to determine if musculoskeletal development had a significant effect on the prediction of body density in females. Subjects consisted of 156 females aged 17 to 44 years. Subjects were divided into three groups on the basis of musculoskeletal development as determined by the Heath-Carter Anthropometric Somatotype mesomorphy rating. Anthropometric measurements included eight skinfold measures (tricep, subscapula, chest, midaxillary, abdomen, suprailiac, thigh, and calf), body diameters of the humerus and femur, and circumferences at five locations (waist, forearm, upper arm, calf, and gluteal). Residual lung volume was determined by the closed circuit oxygen dilution method prior to the measurement of body density by hydrostatic weighing. A regression equation was developed to predict body density from the sum of seven skinfolds, sum of seven skinfolds squared, age, and mesomorphy rating. A similar regression equation was developed using the sum of three skinfolds, sum of three skinfolds squared, and the other variables. Results indicated that mesomorphy rating did not contribute significantly to the prediction of body density in females. It was concluded that musculoskeletal development did not have a significant effect on the prediction of body density in females.
本研究的目的是确定肌肉骨骼发育是否对女性身体密度的预测有显著影响。研究对象包括156名年龄在17至44岁之间的女性。根据希思-卡特人体测量体型法中胚层评级所确定的肌肉骨骼发育情况，将研究对象分为三组。人体测量指标包括八项皮褶测量值（肱三头肌、肩胛下、胸部、腋中、腹部、髂上、大腿和小腿）、肱骨和股骨的身体直径以及五个部位（腰部、前臂、上臂、小腿和臀部）的周长。在通过静水称重法测量身体密度之前，采用闭路氧气稀释法测定残气量。建立了一个回归方程，用于根据七项皮褶测量值之和、七项皮褶测量值之和的平方、年龄和中胚层评级来预测身体密度。使用三项皮褶测量值之和、三项皮褶测量值之和的平方以及其他变量建立了一个类似的回归方程。结果表明，中胚层评级对女性身体密度的预测没有显著贡献。研究得出结论，肌肉骨骼发育对女性身体密度的预测没有显著影响。
