- Abstract
It is known that there are some limitations in reflection the results of scientific studies on the practice in the sports sciences as in other disciplines. Main reason for the gap between research and practice in sports sciences is considered as the reporting approach of only the analysis results and p-value in many studies using null hypothesis. Some researchers have suggested that practical importance of the intervention effect should be focused, arguing that the null hypothesis is always false in the real world. In recent years, it has been emphasized that the research results using the current statistical approach should be supported with methods that appeal to practice, such as the effect size. The aim of this study is to examine models that are suggested to be an alternative to the current statistical approach commonly used in scientific studies and some supportive methods, and to increase to the use of methods considered useful in the field of sports sciences. Although there is a consensus in the literature regarding the reporting of effect size, there are some disagreements regarding the classification of the effect size. Despite some practical advantages of the magnitude-based inferences and the Bayesian statistical models, it is more accepted that it cannot be an alternative to valid statistical approach used in the current conditions. On the other hand, it is stated that the supportive methods that emphasize the smallest important change amount and error terms, which are considered critical in practice, will provide practical benefits in sports sciences. Consequently, although the discussions about the models that can be an alternative to the current statistical approach in the literature continue, there is a widespread consensus that supporting analyzes of the null hypothesis (p-value, statistical significance) with methods for practical use provide important benefits.
