Application and Evaluation of Experimental Design in Sports Science

This paper surveyed the situation of the application about experiment design methods to understand the application status in the experimental design,and avoid potential problems thereby enhancing the sports science research capacity of researchers,which was from 611 theses of the three core journals right from 2000 to 2008.Firstly,establish a preliminary survey indicators through literature and information;and then developed,revised survey indicators,and to determine sample size through the pre-survey 60 papers;exclude the results of the investigation from the formal investigation,which methods is the following year investigation.Conclusions:The application rate,reasonable rate of simple experimental design are higher than the complexity of experimental design;From 2000 to 2008,the experimental design application rate,there is no reasonable method of experimental design showing the gradual increase in complexity,a reasonable trend of gradual improvement;there are some situations of experimental designs misused;against principles of experimental designs is serious.
