Abstract

Coordinative patterns require experience and learning to be acquired, producing movements that offer efficient solutions to various situations and involving certain degree of variability. This coordination variability implies functionality in movement, but it can be impacted by the type of sport practice from early years. The purpose of this work is to analyze the coordination variability and coordination patterns in a specific action such as single-leg landing in children practicing gymnastics, volleyball and non-sporting children.

Thirty children (15 girls) performed 10 successful trials of single-leg landing from a height of 25 cm. A motion capture system (9 cameras) was used to capture 3D thigh and shank kinematics. To identify the significant effect of children's groups on coordination and coordination variability during single-leg landing, one-dimensional Statistical Parametric Mapping (SPM) was used.

Regarding the coordination patterns, in the frontal plane, during the attenuation phase of single-leg landing, the control group exhibited a higher frequency of Anti-Phase with proximal dominancy compared to the sport groups (i.e., gymnastics, and volleyball). In addition, in the sagittal plane during the second peak phase, volleyball players exhibited a higher coordination variability than the gymnastics.

The children in the control group showed a greater frequency of antiphasic movements, which indicates the influence of training at an early age, being a determining factor in the increase or not of variability.

儿童单脚跳落地时的协调性和协调变异性
协调模式需要经验和学习才能获得,它所产生的动作能为各种情况提供有效的解决办 法,并具有一定程度的可变性。这种协调变异性意味着动作的功能性,但它会受到自幼进行的体育锻炼类型的影响。这项工作的目的是分析练习体操、排球的儿童和非运动儿童在单腿着地等特定动作中的协调变异性和协调模式。使用动作捕捉系统(9 个摄像头)捕捉大腿和小腿的三维运动学数据。在协调模式方面,与运动组(即体操组和排球组)相比,在单腿着地的衰减阶段,对照组在正面表现出更高频率的近端优势反相。此外,在第二高峰阶段的矢状面上,排球运动员比体操运动员表现出更高的协调变异性。对照组儿童表现出更高频率的反相位动作,这表明幼年训练的影响是变异性增加与否的决定性因素。

期刊介绍: Human Movement Science provides a medium for publishing disciplinary and multidisciplinary studies on human movement. It brings together psychological, biomechanical and neurophysiological research on the control, organization and learning of human movement, including the perceptual support of movement. The overarching goal of the journal is to publish articles that help advance theoretical understanding of the control and organization of human movement, as well as changes therein as a function of development, learning and rehabilitation. The nature of the research reported may vary from fundamental theoretical or empirical studies to more applied studies in the fields of, for example, sport, dance and rehabilitation with the proviso that all studies have a distinct theoretical bearing. Also, reviews and meta-studies advancing the understanding of human movement are welcome. These aims and scope imply that purely descriptive studies are not acceptable, while methodological articles are only acceptable if the methodology in question opens up new vistas in understanding the control and organization of human movement. The same holds for articles on exercise physiology, which in general are not supported, unless they speak to the control and organization of human movement. In general, it is required that the theoretical message of articles published in Human Movement Science is, to a certain extent, innovative and not dismissible as just "more of the same."
