Neuromotor training can improve motor performance in athletes and patients. However, few data are available about their effect on reaction time (RT). We investigated the influence of video observation/motor imagery (VO/MI) on simple RT to visual and auditory stimuli. The experimental group comprised 21 cadets who performed VO/MI training over 4 weeks. Nineteen cadets completed a sham intervention as control. The main outcome measure was RT to auditory and visual stimuli for the upper and lower limbs. The RT to auditory stimuli improved significantly post-intervention in both groups (control vs. experimental mean change for upper limbs: -40 ms vs. -40 ms, = 0.0008; for lower limbs: -50 ms vs. -30 ms, = 0.0174). A trend towards reduced RT to visual stimuli was observed (for upper limbs: -30 ms vs. -20 ms, = 0.0876; for lower limbs: -30 ms vs. -20 ms, = 0.0675). The interaction term was not significant. Only the specific VO/MI training produced a linear correlation between the improvement in the RT to auditory and visual stimuli for the upper ( = 0.703) and lower limbs ( = 0.473). In conclusion, VO/MI training does not improve RT when compared to control, but it may be useful in individuals who need to simultaneously develop a fast response to different types of stimuli.
神经运动训练可以提高运动员和患者的运动表现。然而,关于其对反应时间(RT)影响的数据却很少。我们研究了视频观察/运动想象(VO/MI)对视觉和听觉刺激的简单反应时间的影响。实验组由21名学员组成,他们进行了为期4周的VO/MI训练。19名学员完成了假干预作为对照。主要结局指标是上肢和下肢对听觉和视觉刺激的反应时间。干预后两组对听觉刺激的反应时间均显著改善(上肢对照组与实验组平均变化:-40毫秒对-40毫秒,P = 0.0008;下肢:-50毫秒对-30毫秒,P = 0.0174)。观察到对视觉刺激的反应时间有缩短趋势(上肢:-30毫秒对-20毫秒,P = 0.0876;下肢:-30毫秒对-20毫秒,P = 0.0675)。交互项不显著。只有特定的VO/MI训练在上肢(P = 0.703)和下肢(P = 0.473)对听觉和视觉刺激的反应时间改善之间产生了线性相关性。总之,与对照组相比,VO/MI训练并不能改善反应时间,但它可能对那些需要同时对不同类型刺激快速做出反应的个体有用。
