1. To determine whether there is the same effect on choice reaction time (RT) tasks using unilateral (UL) and bilateral (BL) thumb flexion responses on the bilateral deficit as simple RT training, 34 students were divided into 5 groups: Simple BL, Simple UL left, Simple UL right, Choice response training, and Control. All students in the training group performed each task through 10 trials x 2 blocks, 3 days per week for 6 weeks. Choice RTs for UL and BL tasks at 3 and 6 weeks were shortened compared to those before training (P<0.05). There was no difference, however, found among the training groups. Therefore, there was no lateral specificity for a choice RT in the effect of training for response speed as simple RT. 2. The degree of bilateral deficit is specifically affected by bilateral and unilateral resistance training in the upper and lower limbs. It has been reported that bilateral deficit is caused by the inhibition of fast motor units. To investigate whether the effect of slow … More and fast isokinetic training differs in the mode of modification of bilateral deficit, 51 students were divided into 4 training groups and a control group: Bilateral fast (BF) and slow (BS) (1.2 and 0.4 m/sec), Unilateral (UF) and slow (US) leg extension training group, and Control. The training groups trained three days a week, for 6 weeks. The degree of bilateral deficit in BF at 1.2 m/sec and that in BS at 0.4 m/sec was decreased by training (P<0.05), while bilateral deficit in US at 0.4 m/sec increased (P<0.05), and that for other conditions was not affected by training. Thus, specificity of effect of training velocity on bilateral deficit was observed only in bilateral training. Lateral specificity observed in this study was more marked at a slow velocity than at a fast velocity, which I speculated may be due to the mechanism of bilateral deficit. 3. To investigate the effect of UL leg extension power training by the right or left leg only on bilateral deficit, 41 students were divided into 5 groups: UL left, UL right, UL left and right, BL training, and Control. All subjects in the training group extended their leg(s) at 1.2 m/sec with maximal power 3 days per week for 6 weeks. The magnitude of bilateral deficit for UL left, UL right, and UL left and right group after training were larger than in the BL training group (P<0.05). Therefore, the effect of UL leg extension power training in the left or right leg only on bilateral deficit was the same as that for UL training performed in both the left and right legs. Less

1.为了确定是否有相同的效果选择反应时（RT）任务使用单侧（UL）和双侧（BL）拇指屈曲反应的双边赤字作为简单的RT训练，34名学生被分为5组：简单BL，简单UL左，简单UL右，选择反应训练，和控制。训练组的所有学生通过10次试验x 2个街区，每周3天，持续6周执行每个任务。3周和6周时UL和BL任务的选择RT较训练前缩短（P<0.05）。然而，在训练组之间没有发现差异。因此，选择反应时间训练对反应速度的影响与简单反应时间训练相比，不存在横向特异性。双侧缺陷的程度特别受到上肢和下肢的双侧和单侧阻力训练的影响。已有研究表明，双侧运动功能障碍是由快速运动单位的抑制引起的。为了研究是否影响缓慢 ...更多信息 将51名学生分为4个训练组和一个对照组：双侧快速（BF）和慢速（BS）训练组（1.2和0.4 m/s）、单侧（UF）和慢速（US）伸腿训练组和对照组。训练组每周训练3天，共训练6周。1.2 m/s时BF和0.4 m/s时BS的双侧缺损程度随训练的进行而减小（P<0.05），而0.4 m/s时US的双侧缺损程度随训练的进行而增大（P<0.05），其他条件下的双侧缺损程度不受训练的影响。因此，只有在双侧训练中才能观察到训练速度对双侧缺陷的影响的特异性。在这项研究中观察到的横向特异性在慢速度比在快速度更显着，我推测这可能是由于双边赤字的机制。3.为探讨单用左腿或单用右腿进行UL伸腿力量训练对双侧肢体功能障碍的影响，将41名大学生分为5组：左侧UL组、右侧UL组、左侧和右侧UL组、BL训练组和对照组。训练组以1.2m/s的速度进行最大力量的伸腿，每周3天，共6周。左侧UL组、右侧UL组、左侧UL+右侧UL组训练后双侧功能缺损程度均大于BL组（P<0.05）。因此，仅在左腿或右腿中进行UL腿部伸展功率训练对双侧缺陷的影响与在左腿和右腿中进行UL训练的效果相同。少
