健步走行为方式的匡正研究

通过问卷调查法、访谈法,分析各个年龄段、不同性别的健步走人群在场地和环境选择、运动前热身、运动中跟着音乐伴奏的速度控制、节奏、运动时间、运动负荷、运动后放松情况等问题,弥补目前调查研究的不足,并提出科学的建议,以帮助人们对健步走的正确认识,找到适合自身的锻炼方式。结论:1)场地选择、准备活动、放松等缺乏科学引导。2)运动中的曲目选择比较单一,音乐节奏没有满足所有健步者的需求;运动速度保持统一节奏,没有做到循序渐进。3)运动后容易出现一些生理上和心理上的损伤。

Establishment of Knowledge Base Management System and the Type Selection of Mechanism for Mechanism Kinematic Scheme

Firstly data standardization technology and combined classification method have been applied to carry out classification of kinematic behaviors and mechanisms in the mapping field between the kinematic behavior level and the mechanism level of conceptual design.The principle of computer coding and storing have been built to give a fast and broad selection of mechanisms that meets the requirements of basic motion characters.Then on the basis of mentioned above,the heuristic matching propagation principle (HMPP) of kinematic behaviors and its true table serves as a guide to perform mechanism types selection.Finally an application is given to indicate its practicability and effectiveness.
