This research is to discuss the different effects dominant legs and non-dominant legs cause on static balance, ground reaction and speed by the following seven evaluation methods of dominant legs: ball-kick, step-up, hop-for-distance, step-forward, balance-recovery, fencing in epee, and individual preference.

摘要本研究的目的在利用七种惯用脚评定方式(踢球、登阶、跳远、往前踩步、恢复平衡、锐剑防卫和个人喜好等七种)，分别探讨惯用脚和非惯用脚在静态平衡能力、对地反作用力和速度之差异性，并发现六种评定方式的信度和七种惯用脚评定方式相互之间的差异性。

By rational designs of mechanical structure and plan, the system uses PLC as the core of control on site, and accomplishes control of the installment and debug of the system step by step by software configuring design of the touch panel. Industrial computer, the centre of monitor, control and management of the system, composes epigyny and hypogyny machines' real-time monitoring and controlling system with PLC by designing the communicative model and program, and accomplishes man-machine dialogue in form of suppositional panel by designing supervisory software. Meanwhile, we also adopt client/server model and realize long-distance supervision of impact sensitivity experiment by program designing.

系统通过合理的机械结构和方案设计，采用PLC作为现场控制核心，通过对触摸屏软件组态设计，完成了系统现场安装、调试时的单步控制功能；作为系统的监控、调度中心的工控微机通过通讯模式和程序设计，与PLC组成上、下位机实时监控系统，间接地实现了对撞击感度试验的监控，并通过上位机实时监控管理软件的设计，以虚拟面板的形式较好地实现了人机对话；采用客户机／服务器模式，通过软件编程实现了撞击感度试验的远程监控功能。
