Anthropometrical characteristics of 3D body segment parameters in swimmers related to developmental advantages of swimming practice in young children

本研究项目旨在探讨持续游泳训练对儿童人体测量生长发育的影响。研究对象为学前和小学儿童，每周进行一次以上的游泳练习，有竞争力的大学和国家级游泳运动员以及久坐不动的人。采用三维全身扫描仪（Hamamatsu Photonics KK）测量全身体积和各节段体积。采用空气置换体积描记仪（BODPOD:LMI）测量全身体积和肺体积等身体组成。游泳者上臂和躯干的相对节段体积明显大于久坐人群。与正常人相比，游泳者的人体测量特征是躯干和躯干的上节段质量相对较大，表明游泳运动的可训练性和优越性。

This research project was designed to investigate the effect of continuous swimming practice on anthropometrical growth and development for children. Subjects were pre and elementary school children who are doing swimming practice more than once a week and competitive collegiate and national class swimmers as well as sedentary persons. Whole body volume and each segmental volume were measured by using three dimensional whole body scanner (Hamamatsu Photonics KK). Body composition including whole body volume and lung volume were measured by using air displacement plethysmography (BODPOD:LMI ). Relative segmental volume for upper arm and trunk in swimmers were significantly larger than those in sedentary peoples. With comparison to normal person, swimmers were anthropometrically characterized as relatively larger segment masses in upper trunk and trunk, indicating trainability and superiority to swimming movements.
