To investigate whether motor control training alters automatic contraction of abdominal muscles in elite cricketers with low back pain (LBP) during performance of a simulated unilateral weight-bearing task.
Clinical trial.
26 male elite-cricketers attended a 13-week cricket training camp. Prior to the camp, participants were allocated to a LBP or asymptomatic group. Real-time ultrasound imaging was used to assess automatic abdominal muscle response to axial loading. During the camp, the LBP group performed a staged motor control training program. Following the camp, the automatic response of the abdominal muscles was re-assessed.
At pre-camp assessment, when participants were axially loaded with 25% of their own bodyweight, the LBP group showed a 15.5% thicker internal oblique (IO) muscle compared to the asymptomatic group (p = 0.009). The post-camp assessment showed that participants in the LBP group demonstrated less contraction of the IO muscle in response to axial loading compared with the asymptomatic group. A trend was found in the automatic recruitment pattern of the transversus abdominis (p = 0.08).
Motor control training normalized excessive contraction of abdominal muscles in response to a low load task. This may be a useful strategy for rehabilitation of cricketers with LBP.
探讨运动控制训练是否会改变患有腰痛（LBP）的精英板球运动员在模拟单侧负重任务时腹部肌肉的自动收缩。
临床试验。
26名男性精英板球运动员参加了为期13周的板球训练营。在训练营开始前，参与者被分为腰痛组或无症状组。使用实时超声成像评估腹部肌肉对轴向负荷的自动反应。在训练营期间，腰痛组进行了分阶段的运动控制训练计划。训练营结束后，重新评估腹部肌肉的自动反应。
在训练营前的评估中，当参与者承受自身体重25%的轴向负荷时，与无症状组相比，腰痛组的腹内斜肌（IO）厚度厚15.5%（p = 0.009）。训练营后的评估显示，与无症状组相比，腰痛组参与者在轴向负荷时腹内斜肌的收缩较少。腹横肌的自动募集模式存在一种趋势（p = 0.08）。
运动控制训练使腹部肌肉在低负荷任务时的过度收缩恢复正常。这可能是腰痛板球运动员康复的一种有用策略。
