本技术报告介绍了一种测量游泳过程中肩部复合体三维关节运动的方法。11名大学游泳运动员在最大努力下进行了前爬泳，并用电磁跟踪装置测量了他们的肩部运动。传感器连接到胸骨，肩峰和肱骨，以确定其相对位置和方向。一辆装有该设备组件的推车沿着泳池边沿着来回推动，这样就可以在电磁场内检测到附着在游泳者身上的传感器。每一个游泳运动员的中风到中风的可靠性测定关节运动。通过测量固定在水面上下移动的木棍上的多个传感器的相对位置和方向来测试设备的准确性。将测量值与预先确定的固定值进行比较。中风周期之间关节角度的变异系数为
This technical report introduces a method for measuring the three-dimensional articular motions of the shoulder complex during swimming. Eleven collegiate swimmers performed front-crawl strokes at maximal effort and their shoulder motions were measured with an electromagnetic tracking device. Sensors were attached to the sternum, acromia and humeri to determine their relative positions and orientations. A cart carrying the components of the device was pushed back-and-forth along the poolside, so that the sensors attached to the swimmer could be detected within the electromagnetic field. The stroke-to-stroke reliability of the measured articular motions was determined for each swimmer. The accuracy of the device was tested by measuring the relative positions and orientations of multiple sensors fixed on a wooden stick moving above and below the water surface. The measured values were compared with pre-determined fixed values. The coefficient of variance for the joint angles between stroke cycles was
