Abstract: Beach handball game is a dynamic sport with high intensity, conducted on a sand court. The inclusion of this sports branch in the Youth Olympic Games program in 2018 held in Buenos Aires, Argentina, elevated the profile of this international sports branch and underscores an increased need for a multitude of performance factors in this sport. The research aim. The research aim was to conduct a comparative analysis of the spinshot technique between an advanced player and a beginner, aiming to gather useful information regarding a technical profile for spinning shots in beach handball and to guide training for enhanced efficiency in this throwing technique. Objectives. Objectives encompassed the analysis of video recordings of two players concerning the angles between body segments and between the body and the ground at various moments during the execution of the technique. Methods and means. For the analysis of throws, video recordings of the executions were performed on two subjects, both beach handball players – one being an advanced player, and the other a beginner. To measure the parameters to be analyzed, including angular characteristics of body segments at key moments during the execution of the spinning shot technique, and the execution times of the two players, Kinovea software v 0.9.5 was utilized. Additionally, trajectory analysis and execution time were examined. Results. In the video analysis of the movement, the force generated by the players is not visible, but it aids in understanding the action and the effects of internal forces (muscle action) and external forces (gravity and friction) on the moving players. The discrepancy between the advanced and beginner players in achieving a half (180⁰) spin in the technical procedure of the spinsshot lies in the flight phase. Execution times are close between the two players, but video analysis revealed differences in the quality of their executions regarding the correct implementation of the spinning shot. Conclusions. The analysis results highlight significant differences in joint amplitude between the two players during spinning shot executions, potentially caused by insufficient muscle group strength, reduced joint mobility, or incorrect mastery of the throwing technique.
