This study examined the effect of the HamSprint Drills training programme and conventional football practice warm-up on lower limb neuromuscular control. The purpose-built active movement extent discrimination apparatus was used to assess lower limb neuromuscular control in 29 footballers from one professional Australian Football League club. Without vision of the contact point, participants performed 40 backward swing movement trials with each leg and made a judgment of the magnitude of each movement. Scores representing the ability to discriminate between different movement extents were calculated as the area under the player's receiver operating characteristic curve, constructed using non-parametric signal detection theory methods. Participants were randomized to either an intervention or control group that performed different procedures in the warm-up prior to football practice sessions over a 6-week period, and then were re-tested. The intervention group performed the HamSprint programme-drills specific to the improvement of running technique, co-ordination and hamstring function. The control group performed their usual warm-up of stretching, running, and increasingly intense football drills. Backward leg swing extent discrimination was significantly better in players following the 6-week HamSprint programme when compared to discrimination scores of players who performed their usual practice warm-up only. Significant improvement was observed in lower limb neuromuscular control in movements similar to the late-swing early stance phase of running. The HamSprint programme can therefore improve control in a specific aspect of sensorimotor system performance, and this may be useful particularly in athletes who have lower function levels or those deemed at risk of hamstring injury.
本研究考察了HamSprint训练计划和传统足球训练热身对下肢神经肌肉控制的影响。使用专门设计的主动运动幅度辨别装置，对来自一家澳大利亚职业橄榄球联盟俱乐部的29名橄榄球运动员的下肢神经肌肉控制进行评估。在看不到接触点的情况下，参与者每条腿进行40次向后摆动运动试验，并对每次运动的幅度做出判断。使用非参数信号检测理论方法构建运动员的接收者操作特征曲线，将代表区分不同运动幅度能力的分数计算为该曲线下的面积。参与者被随机分为干预组或对照组，在为期6周的足球训练课之前的热身中进行不同的程序，然后重新进行测试。干预组进行了针对提高跑步技术、协调性和腘绳肌功能的HamSprint训练计划练习。对照组进行他们通常的拉伸、跑步和强度逐渐增加的足球训练热身。与仅进行常规训练热身的球员的辨别分数相比，进行了6周HamSprint训练计划的球员的向后摆腿幅度辨别明显更好。在类似于跑步后期摆动早期站立阶段的运动中，观察到下肢神经肌肉控制有显著改善。因此，HamSprint训练计划可以改善感觉运动系统表现的特定方面的控制，这可能特别有助于功能水平较低的运动员或那些被认为有腘绳肌损伤风险的运动员。
