The aim of this study was to quantify the differences between groups of elite canoe slalom athletes based on the class they paddle in and the strategies they use in competition. Canoe and kayak footage was recorded using three cameras and analysed using lapsed-time time-motion analysis. Analysis was undertaken on the ten fastest competition runs for men's kayak and canoes and women's kayak for the 22-gate semi-final/final course at the 2005 canoe slalom world championships. Comparison between the categories of paddlers revealed that despite canoe paddlers taking significantly (P < or = 0.05) fewer strokes than kayak paddlers, they were not significantly slower than men's single kayak paddlers with respect to their run times and only significantly slower between 4 of 22 gates. Results revealed also that paddlers using different turn strategies (spin vs. pivot) had significantly (P < or = 0.05) different split times for the gates before and after the execution of the manoeuvre. For a paddler this means that their individual strategy could be analysed and compared with those of others to determine if alternate strategies would be beneficial to their performance.
本研究的目的是根据精英皮划艇激流回旋运动员所参加的级别以及他们在比赛中使用的策略,对不同组别的运动员之间的差异进行量化。使用三台摄像机记录皮艇和划艇的比赛画面,并采用逐帧时间动作分析进行分析。对2005年皮划艇激流回旋世界锦标赛22个门的半决赛/决赛赛道上男子皮艇、划艇以及女子皮艇的十次最快比赛成绩进行了分析。不同划桨者类别的比较结果显示,尽管划艇运动员的划桨次数明显(P≤0.05)少于皮艇运动员,但就比赛用时而言,他们并不比男子单人皮艇运动员明显慢,仅在22个门中的4个门之间明显较慢。结果还显示,使用不同转弯策略(旋转与枢转)的划桨者在动作执行前后的门的分段时间上有显著(P≤0.05)差异。对于一名划桨者来说,这意味着可以分析他们的个人策略并与其他人的策略进行比较,以确定替代策略是否对他们的表现有益。
