[Purpose] Amputee soccer is a game for individuals with amputations. Players use lofstrand crutches to move around the field and kick the ball. Scoring quick goals during a match requires players to have maximum running skills. Notably, a few parameters affect the running speed in players; however, no study has reported the biomechanical analysis of running in amputee soccer. Thus study aimed to analyze the biomechanics of single-leg running using lofstrand crutches in 12 healthy adult males (6 with prior amputee soccer experience and 6 without such experience). [Participants and Methods] The kinematics of the lower limb and the pelvis, the ground reaction force, and skill in using the crutches were evaluated using 3 dimensional motion analysis combined with 8 force plates. Lower leg amputation was simulated in all participants by maintaining the non-dominant knee in a position of maximum flexion using an elastic band. [Results] Significant differences were observed between experienced and non-experienced participants with regard to the angle of the pelvis and the crutch stance phase. Specifically, higher running speed was associated with an increased forward tilt of the pelvis and a shorter crutch stance phase. [Conclusion] These findings will be useful to improve the running speed of amputee soccer players.
[目的] 截肢者足球是一项供截肢者参与的运动。球员使用洛弗斯特兰德拐杖在球场上移动并踢球。在比赛中快速进球要求球员具备最高的跑步技能。值得注意的是，有几个参数会影响球员的跑步速度；然而，尚无研究报道截肢者足球运动中跑步的生物力学分析。因此，本研究旨在分析12名健康成年男性（6名有截肢者足球运动经验，6名无此经验）使用洛弗斯特兰德拐杖单腿跑步的生物力学。[参与者与方法] 使用三维运动分析结合8块测力板评估下肢和骨盆的运动学、地面反作用力以及使用拐杖的技能。通过使用弹力带将非优势膝关节保持在最大屈曲位置，在所有参与者中模拟小腿截肢。[结果] 在骨盆角度和拐杖支撑期方面，有经验和无经验的参与者之间观察到显著差异。具体而言，较高的跑步速度与骨盆前倾增加和拐杖支撑期缩短有关。[结论] 这些发现将有助于提高截肢者足球运动员的跑步速度。
