Abstract

The aim of the study was to determine whether maintaining the standing balance position is influenced by athlete’s symmetric morphological characteristics. Thirty-two healthy sports students participated in this study (age 19.8±1.4 years, body height 182.9±6.8 cm, body weight 79.1±8.1 kg). Morphological characteristics are represented with differences between the left and the right body side of: forearm girth, upper arm girth, calf girth, thigh girth, long shoulder height, lean mass of legs and lean mass of arms. The standing balance result was calculated as a result of factor scores for 9 measurements of 30 seconds (3 measurements of normal standing, 3 measurements of blind standing, and 3 measurements of deaf standing) collected from the pressure insoles system and the difference in ground reaction force between the left and the right leg. Results show that the asymmetric leg load in maintaining standing balance depends on the side differences in the thigh girth and upper arm girth. The greater difference in the thigh girth in favour of the left side resulted in bigger ground reaction force on the right leg compared to the left leg and the greater difference in the upper arm girth in favour of the left side resulted in bigger ground reaction force on the left leg. To avoid one side overload, it is essential for all sports activities to be performed bilaterally.

身体对称如何影响站立平衡?

本研究的目的是确定保持站立平衡位置是否受到运动员对称形态特征的影响。研究对象为32名健康体育学生，年龄19.8±1.4岁，身高182.9±6.8 cm，体重79.1±8.1 kg。形态学特征表现为:前臂周长、上臂周长、小腿周长、大腿周长、长肩高、腿瘦质量和手臂瘦质量。站立平衡结果由压力鞋垫系统采集的30秒内9次测量(正常站立3次，盲人站立3次，聋人站立3次)的因子得分和左腿与右腿的地面反作用力差计算得出。结果表明，维持站立平衡时腿部负荷的不对称取决于大腿周长和上臂周长的侧差。与左腿相比，偏向左侧的大腿周长差异越大，右腿受到的地面反作用力就越大;而偏向左侧的上臂周长差异越大，左腿受到的地面反作用力就越大。为了避免一方负荷过重，所有的体育活动都必须由双方进行。

期刊介绍： Kinesiology – International Journal of Fundamental and Applied Kinesiology (print ISSN 1331- 1441, online ISSN 1848-638X) publishes twice a year scientific papers and other written material from kinesiology (a scientific discipline which investigates art and science of human movement; in the meaning and scope close to the idiom “sport sciences”) and other adjacent human sciences focused on sport and exercise, primarily from anthropology (biological and cultural alike), medicine, sociology, psychology, natural sciences and mathematics applied to sport in its broadest sense, history, and others. Contributions of high scientific interest, including also results of theoretical analyses and their practical application in physical education, sport, physical recreation and kinesitherapy, are accepted for publication. The following sections define the scope of the journal: Sport and sports activities, Physical education, Recreation/leisure, Kinesiological anthropology, Training methods, Biology of sport and exercise, Sports medicine and physiology of sport, Biomechanics, History of sport and Book reviews with news.
