略论运动生物力学的研究方法与测量技术

Discussion on the Research Methods and Measuring Techniques in Sports Biomechanics

文章认为:1,仅依靠牛顿分析力学的研究方法,运动生物力学只能停留在“研究人体机械运动规律”的水平,“走出系统”的研究方法适合于对活体系统的生物力学研究;2,“理论模型”需数据支持才具有应用价值,“数据模型”需相应的数学化才具有理论意义;3,活体运动过程的测量应建立参数采集与测量的标准化和参数分析与评价的专家系统;4,应界定常规参数和敏感参数,并区别参数间的平行关系和因果关系,测量精度的提高主要应依靠测量参数数字化过程的分析方法的进步。

Four topics on research methods and measuring techniques in sports biomechanics were discussed including 1. A new system of research methods that are adaptable to body activities should be used in sports biomechnical studies instead of just relying on the traditional research methods; 2. A theoretical model can only be useful when it is supported by data, and a statistical model can only be of theoretic significance when it is mathematically set up; 3. Standardization for parameters collecting and measuring and expert system for parameters analysis and evaluation should be established for measurement of the process of body activities; and 4. Distinction should be made between conventional and sensitive parameters and between the parallel and causality among parameters. Improvement of measuring accuracy should depend on the progress of the analyzing methods with digital process of the measuring parameters.
