摘要

本研究的目的是描述和比较不同技术水平的攀岩者在使用动态技术时的运动模式。参与者样本为10名登山者，5名高技能登山者和5名低技能登山者。测量了不同身体部位的位置、速度和加速度等运动学变量。采用23点解剖模型和IBV KINESCAN软件对运动模式进行数字化处理。方差分析显示了一些运动变量在技能水平上的差异。具体来说，熟练的攀岩者在冲力阶段获得了更高的质心、髋部和肘部速度。结果表明，动态技术中的技能允许登山者在某些身体部位产生更快的运动，以达到比起始位置更高的抓手位置。Rev.int.med.cienc.act.fís.deporte vol. 21 número 81 ISSN: 1577-0354

DIFERENCIAS EN LOS PATRONES MOTORES DEL GESTO DE LANZAMIENTO EN ESCALADORES

The aim of the present study was to describe and compare the motor patterns of climbers with different skill levels when using the dyno technique. The sample of participants was 10 climbers, 5 high skill climbers and 5 low skill climbers. Kinematic variables of position, velocity and acceleration of different body segments were measured. A 23-point anatomical model, together with the IBV KINESCAN software, were used to digitize the movement patterns. A MANOVA showed differences according to the skill level in some kinematic variables. Specifically, the skilled climbers achieved higher velocity of the centre of mass, hip and elbows during the impulse phase. Results suggest that the skill in the dyno technique allowed climbers to generate faster movements in certain body segments in order to reach a handhold positioned at a higher height than the starting position.
