田径教科书中关于短跑途中跑存在问题商榷

在短跑途中跑中，脚着地后髋关节并未弯曲，而是继续伸展：踝、膝关节是被动弯曲，而不是主动弯曲。此刻主动支撑会缩短制动时间，有利于制动冲量的减小。着地缓冲动作的细致划分，对全面正确地认识跑的原理是必要的，着地缓冲阶段应包括前蹬和后蹬的前一部分(垂直部位至最大缓冲)。摆动腿下压动作的作用有重要意义，应引起足够重视，在跑的划分中应有明确的界定。

A New Approach to Quality Assurance for Higher Education

This article describes the Engineering Professors' Conference (EPC) approach to quality assurance for Higher Education Institutions, which is currently the only formalized alternative to British Standard 5750 'Quality Systems'. The EPC approach is based on principles of quality assurance and Total Quality Management which have been developed in industry. These ideas are briefly outlined, and an opinion expressed on the interpretation and application of BSS7S0 for HE. The EPC model is explained, illustrated with example elements taken from the EPC Specification and Guidelines for Quality Assurance in Higher Education. A top-down approach to the development of an institutional quality system is described, based on a quality policy statement. Areas of activity which have an important impact on the quality of education are identified, emphasising the quality assurance requirements of academic departments. Supporting and administrative quality system requirements are also described, as these also play an important role in the quality of education. Formal quality procedures and documentation in key areas are proposed.     

训练及类固醇药物对动物骨、肌肉肌腱和韧带生物力学特性的影响

本实验对训练动物予以类固醇药物,发现其肌力增强,但工作时间缩短,肌肉断裂强度和能量吸收无改变。胫骨、跟腱、屈趾肌腱和膝内侧副韧带的某些生物力学特性受到不同程度的影响,使其在激烈运动中易于受伤。
