西藏藏族青少年体型

为了探讨藏族青少年体型发育特征及其规律, 本文应用Heath-Carter体型法对2530名藏族青少年体型进行评价。结果发现, 藏族青少年的平均体型男性为偏中胚层的外胚层型(2.40—3.29—3.72),女性为中间型(3.65—2.87—3.32); 男性的体型以外胚层系体型为主(58.52%), 女性体型以内胚层系(32.62%)和外胚层系为主(35.40%); 随着年龄的增长, 藏族青少年的体型发展有一定的规律, 男性由中胚层-外胚层均衡型经偏中胚层的外胚层型又发展回中胚层-外胚层均衡型, 女性由中胚层-外胚层均衡型经历均衡的外胚层型发展为均衡的内胚层型。因此, 本文认为,藏族男性青少年身体的线性程度高、外形上比较瘦削、肌肉较发达; 藏族女性青少年较男性身体的脂肪含量多、线性程度相对较高。

Somatotypes of Tibetan Adolescents in Tibet

To study the characteristics and patterns of somatotypic growth in Tibetan adolescents, somatotypes of 2530 Tibetan adolescents were evaluated using the Heath-Carter anthropometric method. In this research, we found that the average somatotype of males was mesomorphic and ectomorphic (2.40 —3.29 —3.72) whereas in females, the average somatotype was central (3.65 —2.87 —3.32). The primary somatotype in males was ectomorphy (58.52 %) and endomorphy in females (32.62 %). It was noted that with increasing age, male somatotypes developed from mesomorph-ectomorphy, mesomorphic-ectomorphy to mesomorph-ectomorphy, however in females the pattern is from ectomorph- endomorphy, balanced ectomorphy, ectomorph-endomorphy ectomorphic endomorphy to balanced endomorphy. It is concluded that the somatotypes of Tibetan adolescent males and females are slender with males being more muscular and females having more body fat.
