To invcsitigate a effect of aging on body composition the thickness of a subcutaneous adipose tissue and muscle at 12 positions of human body were mesured by means of ultrasonic method. The thickness of muscle at evely positions of body indicated to decrease by aging from 30 to 70th years olds. Especially the muscles of lower extremities such as thigh and leg decreased by 50% at 70 years. Bone mineral density measured by DEXA method indicated to decrease with the age, and there were significant linear relationship between bone density and muscle thickness or muscle power output. By 13 weeks of aerobic training the subcutaneous fat and visceral fat decreased significantly, and the decrease of subcutaneous fat thickness correlated to the training freaquency, i.e.the higher frequency of training the decrease of fat was larger.From these results1) with the age muscle thickness at various body positions decreased significnatly2) the bone mineral density related to the muscle power or muscle thickness3) by aerobic exercise subcutaneous fat thickness and visceral fat mass decreased significantly.

为探讨增龄对人体组成的影响，用超声波法测定了人体12个部位皮下脂肪组织和肌肉的厚度。从30岁到70奥尔兹，身体各部位肌肉厚度随年龄增长呈下降趋势。特别是下肢肌肉，如大腿和小腿，在70岁时减少了50%。DEXA骨密度随年龄增长而降低，骨密度与肌肉厚度、肌肉输出功率呈显著线性关系。有氧训练13周后，皮下脂肪和内脏脂肪明显减少，皮下脂肪厚度的减少与训练频率有关，结果表明：1）随着年龄的增长，各体位肌肉厚度均显著降低; 2）骨密度与肌力或肌肉厚度相关;有氧运动使皮下脂肪厚度和内脏脂肪量显著降低。
