摘要

外部因素的影响会使个体的体型分布明显偏离一般人群的指标,这就要求研究者从已知的体型分型方案中选择最合适的体型分型方案,或者自行构建体型分型方案。军事大学的申请者是这类样本中的一个特例,是军事医学委员会工作等复杂因素的结果。目的是使用聚类分析来制定一个综合分类,以评估实际健康的青少年的身体发育。材料和方法。这项研究的对象是280名申请者(234名男孩和46名女孩),他们由军事军需处医疗委员会的专家进行了检查,被认为实际上健康。分析人体测量数据:体长、体重、躯干和四肢的长度、躯干和四肢的周长尺寸以及身体成分组成。采用Ward方法进行层次聚类分析,采用Kendall相关系数进行分析。结果。通过对虚拟健康个体身体发育指标的聚类分析,我们发现体重指数、体重、体长在形成3个主要群体中有显著贡献,我们将其描述为:男性大体细胞表型、男性中体细胞表型和女性表型。根据肌肉和脂肪组织比例、内脏脂肪、作为骨骼发育指标的前臂远端直径、体重指数和前腹壁皮肤脂肪褶厚度,确定了以下亚组:男性大体细胞表型,具有肥大特征,男性大体细胞表型,具有正常特征,男性中体细胞表型,具有消化特征,男性中体细胞表型,具有中紧张性特征,男性中体细胞肌肉表型,女性巨大体运动和亚运动表型,女性狭窄表型。结论。所使用的统计方法允许改变寻找身体分型的通用方法的经典范式,以创建在选定的人口群体中编写众所周知的身体发育评估方案的算法。

CLUSTER ANALYSIS AS AN INTEGRATOR OF DIFFERENT TECHNIQUES FOR ASSESSING THE PHYSICAL DEVELOPMENT OF HEALTHY ADOLESCENTS
The influence of external factors can significantly deviate the distribution of somatotypes from the indicators of the general population, which makes researchers select the most suitable scheme of so-matotyping from the already known ones or construct their own. Applicants of military universities are a particular case of such samples, formed as a result of a complex of factors, including the work of military medical commissions. The aim was to use cluster analysis to develop an integrative classifica-tion for assessing the physical development of practically healthy adolescents. Materials and meth-ods. The object of the study was 280 applicants (234 boys and 46 girls), who were examined by spe-cialists in the medical commissions of military commissariats and were considered to be practically healthy. Anthropometric data were analyzed: body length, body weight, length of the torso, limbs, girth dimensions of the torso and limbs, as well as body component composition. Hierarchical cluster analysis by the Ward method and Kendall's correlation coefficient were used in the study. Results. By means of cluster analysis of the physical development indicators of the virtually healthy individuals, we identified a significant contribution of body mass index, weight, body length in the formation of three major groups, which we characterized as: the male macrosomatic phenotype, the male mesoso-matic phenotype, and the female phenotype. Based on the proportion of muscle and fat tissue, visceral fat, distal diameter of the forearm as an indicator of bone development, body mass index and thick-ness of the skin-fat fold of the anterior abdominal wall, the following subgroups were identified: male macrosomatic phenotype, with hyperstenic features, male macrosomatic phenotype, with normosthen-ic features, male mesosomatic phenotype with digestive features, male mesosomatic phenotype with mesotonic features, male mesosomatic muscle phenotype, female megalosomic athletic and subathletic phenotype, female stenoplastic phenotype. Conclusion. The used statistical approach allows to change the classical paradigm of searching for a universal methodology of somatotyping, to the creation of algorithms of compilation of well-known schemes of physical development evaluation in the selected population groups.
