The study about the studying -teaching theory in Heavy Gymnastics utirizing the robot and computer simuration.

日本学龄儿童在“重体操”学习中存在的问题，主要是由于“重体操”学习过程中存在的身体和心理风险，以及他们幼年对体育锻炼的实际体验较少。这项研究在步骤1之后进行了分析。整理“重体操”技巧。从力学和生理学两方面对单杠技术进行了分析。运用“重体操”机器人和计算机模拟实验，考察了机械原理教学方法。编制了“副体验”与“真实体验”的对接程序，研究结果如下：1.将单杠技术从单杠动作拓展到摆动和旋转动作。单杠的旋转运动实现了上肢和下肢的平衡。平衡铸型采用双侧肢体关节屈伸平衡。小学生对单杠机器人和计算机模拟产生了极大的兴趣。利用单杠机器人的对位经验和计算机仿真，是研究机械原理的有效方法。对腹部区域的压力推测为下肢关节屈曲和伸展的触发信号，需要进一步详细检查。

Japanese school childrem have trouble in the "heavy gymnastics" studying.The big reasons are the bodily and mentally risks during "heavy gymnastics" studying, and their small real-experience of physical exercise in infancy.In this study, the safety and efficiency studying -teaching theory of the "heavy gymnastics" were analyzed. This study was analyzed following steps.1. Put in order the "heavy gymnastics" skills.2. Analyzed the skills of the horizontal bar mechanically and physiologically.3. Examined the teaching method of mechanial theory using the "heavy gymnastics" robot and the computer simulations.4. Developed connection program for the 'para-experiences' to the 'real-experiences'.The result of this study were as follows :1. The skills of horizontal bar are expanded from chinning to the swing and the rotatory motion.2. The rotatory motion of the horizontal bar materialized to cast the balance of the upper body and the lower limbs.3. The balance casting were performed flexion and extension of the lower limb joints.4. School children took a great interest in the horizontal bar robot and computer simulations.5. The para-experience by using the horizontal bar robot and computer simulations was effective to study the mechanical theory.6. The pressure to the abdominal region that presumed the trigger signal for the flexion and extension of the lower limb joints require further examinations in detail.
