The aim of the study was to develop a method for measurement and analysis of kinematics of the pelvic girdle movement in breaststroke swimming to support training of technical skills. The measurements were performed in five elite breaststroke swimmers. A recording device for triaxial accelerations and triaxial rotational angular velocity was mounted on the dorsal part of the pelvic girdle of the athlete. The task of the athlete was to swim one length of the 50 m swimming pool with the intensity similar to competition. From the consecutive cycles of swimming motion, we developed individual mean graphical and numerical profiles of the kinematics of the pelvic girdle movement within the average cycle. Mean basic values of the characteristics were compared with the values documented in the literature obtained by means of the video analysis or using the method of measurement of the velocity of the unwound rope. The comparison revealed that the results in the group studied were very similar to the results obtained using other methods and were typical of elite athletes. Analysis of the motion profiles for the pelvic girdle in breaststroke swimmers indicated that the results obtained reflected individual technique of performing individual phases of swimming cycles. The proposed measurement method, presentation and analysis of the profile of the pelvic girdle motion in breaststroke swimming represents a good tool for fast and effective biomechanical evaluation of motion technique components.
本研究的目的是开发一种用于测量和分析蛙泳中骨盆带运动学的方法，以支持技术技能训练。对五名优秀蛙泳运动员进行了测量。一个用于记录三轴加速度和三轴旋转角速度的装置安装在运动员骨盆带的背部。运动员的任务是以与比赛相似的强度游完50米游泳池的一个长度。从连续的游泳动作周期中，我们绘制了平均周期内骨盆带运动学的个体平均图形和数值曲线。将这些特征的平均基本值与通过视频分析或使用解绕绳索速度测量方法在文献中记录的值进行了比较。比较结果表明，研究组的结果与使用其他方法获得的结果非常相似，是优秀运动员的典型特征。对蛙泳运动员骨盆带运动曲线的分析表明，所获得的结果反映了游泳周期各阶段的个体技术。所提出的测量方法、蛙泳中骨盆带运动曲线的呈现和分析是对运动技术成分进行快速有效生物力学评估的良好工具。
