项目摘要

Bilateral deficit, also known as bilateral deficit in movement speed, has been defined as a reduction in force that accompanies maximal two-limb efforts of the homologous limbs relative to single performance ; that is, the reaction time(RT) is longer for simultaneous bilateral responses than for unilateral ones. Although we know that this phenomenon is mediated by neural mechanisms such as interactions between the cerebral hemispheres or spinal reflexes, the underlying mechanism is still far from clear. The purpose of this study was to examine bilateral deficit in children whose nervous system was not yet completely mature, and to clarify the developmental characteristics of bilateral and unilateral movements.Subjects (aged 6-11 children) were asked to perform a RT task by a handgrip either by a single hand or by both hands in response to auditory stimuli. The RT and grip strength ware measured in each trial.The results are as follows. The bilateral deficit phenomenon was not notably o … More bserved compared with the adult by the child as same as previous reports. By those children, nerve bunches, such as a corpus callosum which connects the both sides of a cerebrum, are still mature phases, and this was considered that it is one factor that the exchange of a right-and-left hemisphere is underdeveloped. Moreover, a possibility that facilitative function, such as ipsilateral pathway, was working in predominance rather than the integration and the mutual inhibition between the cerebral hemispheres.In present study, it was presumed that facilitation rather than inhibition occurred in the children as they carried out a bilateral simultaneous movement, that is, a kind of maximal effort when they responded as fast as possible. I hypothesized that different mechanisms may be responsible for fast bilateral movement in children.These results ware reported at the academic meeting of International Society of Biomechanics(2003.7), Japanese Society of Growth and Development(2004.3), and as an article of Bulletin of Institute of Physical Education, Keio University(2005.1) Less

双侧缺陷，也称为双侧运动速度缺陷，被定义为相对于单一表现，伴随着同源肢体的最大双肢努力的力的减少;也就是说，反应时间（RT）对于同时双侧反应比单侧反应长。虽然我们知道这种现象是由大脑半球或脊髓反射之间的相互作用等神经机制介导的，但其潜在机制仍远不清楚。本研究的目的是探讨神经系统尚未完全发育成熟的儿童的双侧缺陷，并阐明双侧和单侧运动的发展特点。被试（6-11岁）被要求执行RT任务，由一只手或双手对听觉刺激作出反应。每一次试验均测量RT和握力，结果如下。双侧亏损现象不明显， ...更多信息与成人相比，儿童的观察结果与以前的报告相同。对于这些儿童，神经束，例如连接大脑两侧的胼胝体，仍然是成熟阶段，这被认为是左右半球交换不发达的一个因素。此外，还存在同侧通路等易化功能起主导作用的可能性，而不是大脑两半球之间的整合和相互抑制作用，本研究假设儿童在进行双侧同时运动时，即在尽可能快地做出反应时的最大努力时，发生的是易化而不是抑制。我推测儿童快速双侧运动的机制可能不同。这些结果在国际生物力学学会学术会议（2003.7）、日本生长发育学会学术会议（2004.3）和庆应义塾大学体育研究所通报（2005.1）上发表。
