We aimed to compare the match-play and kinematic demands of the translation and rotation movements of elite wheelchair padel players as a function of match results. Twenty-two elite male players were video-analysed with a two-dimensional direct linear transformation (DLT) -corrected video system across seven matches of a professional tournament. Distance, turns, changes of direction, linear and angular speed, acceleration and the players' heart rate (HR) were recorded. Losing couples in wheelchair padel covered greater distances than winners (P <0.001; r = 0.024) and did so at a higher speed (P <0.001; r = 0.06), while making greater efforts by accelerating (P <0.001; ∅ = -0.021), braking (P <0.001; ∅ = -0.014), and remaining less time stationary (P <0.001; ∅ = 0.059). In addition, losers performed more turns per rally (P <0.001; r = 0.04) at a faster speed, greater angular accelerations (P <0.001; V = 0.06) and greater average (P = 0.007; d = 0.91) and maximum (P = 0.20; d = 0.69) HR values. These data suggest that winner couples performed a better court positioning and employed a strategy to move the opponent during rallies in order to avoid them optimally reaching the ball.
我们旨在比较精英轮椅壁球运动员在比赛结果的影响下，转体和旋转动作的比赛和运动学需求。通过二维直接线性变换（DLT）校正视频系统，对 22 名精英男性运动员在一个职业巡回赛的 7 场比赛中进行了视频分析。记录了距离、转弯、变向、直线和角速度、加速度和运动员的心率（HR）。在轮椅壁球比赛中输的组合比赢的组合覆盖了更大的距离（P <0.001；r = 0.024），并且速度更高（P <0.001；r = 0.06），同时通过加速（P <0.001；∅ = -0.021）、制动（P <0.001；∅ = -0.014）和保持静止时间更短（P <0.001；∅ = 0.059）付出了更大的努力。此外，输的组合每回合完成更多的转弯（P <0.001；r = 0.04），速度更快，角加速度更大（P <0.001；V = 0.06），平均心率（P = 0.007；d = 0.91）和最大心率（P = 0.20；d = 0.69）值更高。这些数据表明，获胜组合在比赛中更好地定位了球场，并采用了一种策略来移动对手，以使其无法最佳地触球。
