This study highlights the relationship of the biomechanical characteristics and the movement radius of body segments during the execution of Yurchenko handspring vault by the female gymnasts of 14-16 years old. Thus an experimental study was conducted in 2014 at the “Sidney 2000” Olympic Centre of Izvorani, with a group of 7 gymnasts aged 14 to 16, belonging to the national women’s artistic gymnastics team. Research methods: review of the specialised literature; pedagogical observation; experimental study method; computerised video method using Kinovea and Physics ToolKit specialised programs; method of postural orientation movement for sports technique analysis; statistical-mathematical method and graphical representation of data with KyPlot program. The results of the study show the relationship of the kinematic and dynamic characteristics of sports technique key elements and the body segments movement radius during the Yurchenko vault. It also shows the influence of arm movement radius related to the other body segments on the technical execution depending on the vault difficulty and type and the performances achieved in competition. Regarding the correlation of the biomechanical characteristics indicators with the performances in handspring vaults, we notice significant differences at p0.05, p0.01 and p0.001, which confirm the influence of arm radius and body segment movement on the technical execution of the handspring vaults in the gymnasts of 14-16 years old
