以尼克莱·伯恩斯坦的“协调观”运动控制理论为基础，探索皮艇划浆动作中躯干与上肢的协调方式，为皮艇技术的诊断提供新视角。国内首次采用三维摄像技术对皮艇划浆动作中躯干与上肢的运动学参数进行测量，通过连续相对时段方法对躯干与左臂、躯干与右臂的协调关系进行定量分析。研究结论：（1）在划桨时段中，躯干与划桨侧手臂正相位协调程度呈现“降低一提高一降低”的变化。在划桨过程中，首先主要依靠躯干运动，然后依靠躯干与划桨侧手臂共同运动，接着主要依靠划桨侧手臂的运动；（2）在右划桨时段末期，躯干与右手臂协调还存在一个提高的过程，这可能是由于躯干与右手臂还存在一个撑桨动作；（3）躯干与左上肢的协调变异性显著小于躯干与右上肢，这表明躯干与左上肢协调的控制水平相对要低些；（4）躯干与右上肢的协调关系在左桨阶段较松弛，在右桨阶段比较紧密，这体现了躯干与右上肢协调的周期节奏性。

Based on motion control theory of Nicolai Berustein＇s view of coordination, the effective coordination mode among human body joints in Kayak was studied and a new angle for Kayak technique diagnosis was provided. And three-dimensional camera shooting technique was initially adopted in China to measure the kinematics parameters of trunk and upper limb. After that the compatible relationship between the trunk and the left arm and the counter- part was quantified through the method of continuously relative time period. Conclusion： 1. During the pulling phase, the coordination degree between the trunk and the pulling arm showed ＂decreased-increased-decreased＂. The pulling motion starts from the trunk movement mostly, and then the trunk and the pulling arm work together. And after that it ends with the pulling ann. 2. At the end of the right arm＇s pull, there was an enhancement of the coordination degree between the trunk and the right arm. It might be caused by the punt by the trunk and the right arm at the end of the right ann＇s pull. 3. The significance of coordination variation between the trunk and the left ann is less obvious than the right side. It indicated low control level of coordination between the trunk and the left arm. 4. The coordination relationship between the trunk and the right ann during the left arm＇s pull was loose while it was close during the right ann＇s pull. It reflected cycle rhythmicity of the coordination between the trunk and the right ann.
