由于受生物、社会、教育、心理等方面因素影响及学科发展的不健全 ,体育教学训练实验表现较大的复杂性、独特性 ,受到一定的限制。从实验对象、施加因素、实验指标、教学方法、实验设计、效度等环节与方面 ,对体育教学训练实验受限性及如何尽可能降低其影响进行了探讨 ,以期促进体育教学训练实验更具科学性、合理性 ,使实验研究更好地为体育教学训练实践服务 Due to the influence of biological, social, educational and psychological factors and the imperfect development of disciplines, the physical education training experiment shows great complexity and uniqueness, and is limited to some extent. From the aspects of experiment object, exertion factor, experiment index, teaching method, experiment design, validity and other aspects and aspects, this paper discusses the limitation of PE teaching experiment and how to minimize its impact, in order to promote the PE teaching experiment more Scientific and reasonable, so that experimental research can better serve physical education and training practice
