Science advancement in all disciplines, including sports science, is rapidly growing, which requires an upgrade of knowledge of all parties that are involved and active in the world of sports and coaching to improve sports performance. Regarding the development of sports science related to the increase of short distance running (sprint) speed, many studies have been conducted on the factors that increase the running ability, including leg length. The structure and function of the human body allows to understand how the body responds to a stimulus. This study aims to describe the effect of leg length on improving short distance running (sprint) performance through a meta-analysis. The population in this study included documents related to the correlation between leg length and sprint speed. Purposive sampling technique was employed to collect the research sample, in which the sample was determined based on the suitability of the research theme, and the collected sample must meet the following criteria: (1) made by students or lecturers; (2) published from 2010 to 2018; (3) is quantitative research; (4) discusses the relationship or effect of leg length on the sprint speed. The data were acquired by documenting research articles in Indonesia from various sources collected through the Google search engine. The random-effects model was applied for data analysis using the JASP 0.9.1 software. This software was used to calculate the mean aggregate difference and to draw forest plots and publication bias. Rank correlation and regression, Trim and Fill methods, were employed to identify the existence of publication bias, which indicated that there was no publication bias in this meta-analysis. The obtained results showed that there was a significant correlation between the leg length and speed in short distance running with the correlation value (r) = 0.6801. Long legs allow a wider angle of movement within a certain limit in sports such as running. With a wide angle, the maximum speed is obtained. It can be concluded that there is a significant effect between the leg length and speed in short distance running. © JPES.
