We have examined the bone condition of Japanese children and adolescents using the sound transmission test of bone. As for bone condition, it has become clear that there is a difference resulting from sex, age and exercise experience in subjects in growth and development stage. The sound transmission test of bone has revealed that the bone condition rapidly develops when a person is between 11 and 16 years old. Bone conditions become remarkably different from each other between boys and girls after they are 14 years old. After subjects are 16 years old, the peak frequency becomes stable at the means of 130-133 Hz among boys, and 120-123 Hz among girls.The exercise group shows a higher peak frequency than the nonexercise group does. A continuous exercise can be effective to improve the bone condition of school-age children.Every percentile curves of boys clearly tend to rise with increasing age. Those of girls do not change except for 97%ile curve, which improves like the boy's pattern.

我们使用骨的声音传输测试来检查日本儿童和青少年的骨骼状况。对于骨骼状况，已经清楚的是，在生长发育阶段的受试者中存在性别、年龄和运动经历的差异。骨的声音传输测试表明，当一个人在11至16岁之间时，骨骼状况迅速发展。14岁以后，男孩和女孩的骨骼状况变得明显不同。16岁以后，男性峰值频率稳定在130-133 Hz，女性峰值频率稳定在120-123 Hz，运动组峰值频率高于非运动组。一次持续的运动可以有效改善学龄期儿童的骨骼状况，男生各百分位曲线随年龄的增长有明显的上升趋势。女生的曲线除97%的ile曲线与男生的曲线相似外，其余无明显变化。
