摘要
确定性模型是指不包含任何随机成分的模型,作为一种建模范式,可以确定运动项目测量结果和对应测量结果的生物力学因素的关系。结合实例介绍了运动生物力学研究中确定性模型的建模过程,回顾了确定性模型的研究历史,分析了应用确定性模型的优缺点。在过去30年中,确定性模型已成功应用于田径、游泳、体操等项目,也成功应用于选定运动技能。确定性模型方法有助于避免随意选择表现或者损伤变量,识别影响运动表现的关键特征因素,可为影响运动表现结果的相关因素提供理论基础,结合定性分析较好的分析运动表现;然而其对表现结果的测量带有主观性,忽略重要的技术变量。建议运动生物力学学者考虑使用确定性模型时,确定研究中有意义的因变量。
As a modeling paradigm, deterministic model does not contain any random component and is used to identify the relationship between the out come of sport performance measure and biomechanical factors that produce such a measure. In this study, the modeling process about deterministic models is fully elaborated combined with some examples, and the history of deterministic models research is review, and the advantages and disadvantages of de terministic models are analyzed. The deterministic model approach has been successfully in technique analysis such as swimming, athletics field events, and gymnastics over the last three decades. In addition, it has been used in selecting movement skills. The deterministic model approach can help to avoid selecting performance or injury variables arbitrarily, and to identify critical features influenced sport performance, and to provide the necessary theoretical basis for examining the relative importance of various factors. But the use of subjective measures for the performance outcome and Ignore important techni cal variables exists sometime. It is recommended that sports biomeehanics scholars should consider using deterministic models to help identify meaningful dependent variables in their studies.
