Sprint and technique abilities of Para ice hockey players are of great importance to increase skating performance. To assess skating abilities, kinematics is widely used. This study had two purposes: (1) to assess two-dimensional kinematics of Para ice hockey players’ performance in the laboratory and on ice (sprint and agility) tests and (2) to quantify the relationship between the laboratory and on ice performance. Seven athletes were recruited. In the laboratory, three alternated reach tests were performed in which athletes touched the ground as many times as possible with hands, elbows, or shoulders. The sprint test consisted of 30-m skating at the highest speed starting from standstill, whereas the agility test consisted of sprinting for four left curves and four right curves. Athletes’ movements in the laboratory and on ice tests were acquired using a portable technology. In the laboratory, the best performance was realized when participants touched the ground with hand or elbow. In the sprint test, lower speed and trunk inclination were observed in the first 10 m. In the agility test, greater blade angle was observed in the left curves, compared with the right curves. Significant correlations were found between the laboratory and on ice test performance. Overall, these findings are a useful indicator of athletes’ skating abilities and could be used to increase athletes’ ability to accelerate rapidly and improve sledge manoeuvrability. For detailed player information, kinematics should still be evaluated using sport specific tests and video analysis.

实验室和冰上测试以评估残疾人冰球运动员的运动学

残疾人冰球运动员的冲刺和技术能力对于提高滑冰成绩非常重要。为了评估滑冰能力,运动学被广泛使用。本研究有两个目的:(1) 评估残疾人冰球运动员在实验室和冰上(冲刺和敏捷)测试中的表现的二维运动学,以及 (2) 量化实验室与冰上性能之间的关系。招募了七名运动员。在实验室中,进行了三项交替的伸展测试,其中运动员用手、肘部或肩部尽可能多地接触地面。冲刺测试包括从静止状态开始以最高速度滑行 30 米,而敏捷测试包括冲刺四个左弯道和四个右弯道。运动员在实验室和冰上测试中的动作是使用便携式技术获得的。在实验室中,当参与者用手或肘部接触地面时,表现最佳。在冲刺测试中,在前 10 m 中观察到较低的速度和躯干倾斜度。在敏捷性测试中,与右侧曲线相比,在左侧曲线中观察到更大的叶片角度。在实验室和冰上测试性能之间发现了显着的相关性。总体而言,这些发现是运动员滑冰能力的有用指标,可用于提高运动员快速加速和改善雪橇机动性的能力。对于详细的运动员信息,仍应使用运动特定测试和视频分析来评估运动学。当参与者用手或肘部接触地面时,表现最佳。在冲刺测试中,在前 10 m 中观察到较低的速度和躯干倾斜度。在敏捷性测试中,与右侧曲线相比,在左侧曲线中观察到更大的叶片角度。在实验室和冰上测试性能之间发现了显着的相关性。总体而言,这些发现是运动员滑冰能力的有用指标,可用于提高运动员快速加速和改善雪橇机动性的能力。对于详细的运动员信息,仍应使用运动特定测试和视频分析来评估运动学。当参与者用手或肘部接触地面时,表现最佳。在冲刺测试中,在前 10 m 中观察到较低的速度和躯干倾斜度。在敏捷性测试中,与右侧曲线相比,在左侧曲线中观察到更大的叶片角度。在实验室和冰上测试性能之间发现了显着的相关性。总体而言,这些发现是运动员滑冰能力的有用指标,可用于提高运动员快速加速和改善雪橇机动性的能力。对于详细的运动员信息,仍应使用运动特定测试和视频分析来评估运动学。与右曲线相比,在左曲线中观察到更大的叶片角度。在实验室和冰上测试性能之间发现了显着的相关性。总体而言,这些发现是运动员滑冰能力的有用指标,可用于提高运动员快速加速和改善雪橇机动性的能力。对于详细的运动员信息,仍应使用运动特定测试和视频分析来评估运动学。与右曲线相比,在左曲线中观察到更大的叶片角度。在实验室和冰上测试性能之间发现了显着的相关性。总体而言,这些发现是运动员滑冰能力的有用指标,可用于提高运动员快速加速和改善雪橇机动性的能力。对于详细的运动员信息,仍应使用运动特定测试和视频分析来评估运动学。
