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

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.
