摘　　要：在总结国内外研究工作的基础上提出了基于实测桨力和船体加速度信息的皮艇专项竞技能力评价指标体系的建立方法,采用因子分析法提取出了桨频、绝对船速差、船体颠簸和摇晃加速度、拉桨平均桨力、最大桨力衰减、桨力平坦度和拉桨节奏等11项代表性指标构成静水皮艇专项竞技能力评价指标体系,简明有效地反映了运动员的身体素质、专项力量素质、动力保护和拉桨控船技术等专项竞技能力。This paper proposed a method based on on-water measurement of paddle force and acceleration of boat to establish the evaluation indicator system of kayak specialized competitive capability. Eleven representative indicators such as stroke rate, boat velocity difference, bump acceleration of boat, wobble acceleration of boat, average paddling force, maximal attenuation of paddle force, smoothness of paddle force and paddle rhythm were extracted from sixty evaluation indicators, and the eleven representative indicators were utilized to establish the evaluation indicator system of kayak specialized competitive capability, the indicator system concisely and effectively reflected the comprehensive competitive capability, including physical fitness, special ized power quality, power protection, paddle and boat control teehniqes.
