The objectives of this study were to examine the consequences of an acute hamstring injury on performance and mechanical properties of sprint-running at the time of returning to sports and after the subsequent ~2 months of regular soccer training after return. 28 semi-professional male soccer players, 14 with a recent history of unilateral hamstring injury and 14 without prior injury, participated in the study. All players performed two 50-m maximal sprints when cleared to return to play (Test 1), and 11 injured players performed the same sprint test about 2 months after returning to play (Test 2). Sprint performance (i. e., speed) was measured via a radar gun and used to derive linear horizontal force-velocity relationships from which the following variables obtained: theoretical maximal velocity (V(0)), horizontal force (F(H0)) and horizontal power (Pmax). Upon returning to sports the injured players were moderately slower compared to the uninjured players. F H0 and Pmax were also substantially lower in the injured players. At Test 2, the injured players showed a very likely increase in F(H0) and Pmax concomitant with improvements in early acceleration performance. Practitioners should consider assessing and training horizontal force production during sprint running after acute hamstring injuries in soccer players before they return to sports.
本研究的目的是，在恢复运动时以及恢复后进行约2个月的常规足球训练后，检查急性腘绳肌损伤对短跑成绩和力学性能的影响。28名半职业男性足球运动员参与了该研究，其中14名近期有单侧腘绳肌损伤史，14名无既往损伤史。所有运动员在获准恢复比赛时进行两次最大50米短跑（测试1），11名受伤运动员在恢复比赛约2个月后进行相同的短跑测试（测试2）。通过雷达测速仪测量短跑成绩（即速度），并据此得出线性水平力-速度关系，从中获得以下变量：理论最大速度（V(0)）、水平力（F(H0)）和水平功率（Pmax）。恢复运动时，受伤运动员比未受伤运动员速度稍慢。受伤运动员的F H0和Pmax也显著更低。在测试2中，受伤运动员的F(H0)和Pmax很可能增加，同时早期加速成绩有所改善。从业者应考虑在足球运动员急性腘绳肌损伤恢复运动前，评估和训练短跑时的水平力产生情况。
