摘要
1)高原地区青少年骨骼发育晚熟比率大于早熟比率,正常比率为54.70%,晚熟比率为38.20%,早熟比例为7.10%。2)高原地区青少年发育不同指标的差异分析表明,在0.05差异显著性水平下,不同单位的龄差存在差异,是否独生子女的龄差存在差异,不同性别的龄差不存在差异,不同民族的龄差不存在差异。3)鉴于高原地区因遗传或特殊环境造成的青少年整体发育相对较为(晚)(龄差均值=-0.742)特殊性,就高原地区青少年耐力性运动员初级选材而言,其龄差标准应在参考国家标准(龄差绝对值≥2)的基础上,以新标准(龄差≤-2.5或龄差>1.0)为主。
Because the significance of the Adolescent Bone Age Characteristics （ABAC） velopmental assessment and Endurance Athletes Primary Selection （EAPS）, this. paper for the deadopts the methods of measurement, literature, statistics and survey to study the ABAC and EAPS in plateau region. The findings indicate that ： the bone developed normally ratio was 54.70%, the early matu- rity ratio was 7.10%, late - maturing ratio was 38.20%. The results revealed that there are differ- ences of bone age in units and whether the only - child except sex and nations in the 0.05 significant level. Because the particularity of the high late - maturing ratio （ mean age difference = - 01742 ）, the standards of ABAC should be reference for national standards （age difference absolute value 2） and base on the new standard （≤ - 2.5 or age difference 〉 1.0 ） in Yunnan Province＇.
