Biomechanical performance assessment of overhead backhand smash strokes of male badminton players

Badminton is a world-famous game that is played by a large population. The evolution of badminton equipment, particularly racquets and shuttlecocks, has played a crucial role in the sport's development. As badminton has evolved, so have the techniques and strategies employed by players. Enhancing strategy can be achieved by closely observing the player's biomechanics while performing the strokes. Various biomechanical measurements can be obtained using video analysis. Methods: A total of 10 subjects were selected for the execution of strokes, and certified coaches conducted subjective analyses. Videography was employed in the study, focusing specifically on backhand overhead smash strokes. The angles of the ankle, knee, elbow, and wrist joints at the point of contact were analysed. These phases of the skill were extracted from the videography and processed using Kenova 0.8.27 software, which generated stick figures of the selected phases. From these figures, the relevant biomechanical variables were obtained. Conclusion: In conclusion, The biomechanical analysis of backhand overhead strokes in badminton using Kenova software provides valuable insights into the mechanics of effective stroke execution. By examining joint angles and movements at the point of contact, we can identify key factors that contribute to stroke efficiency, power, and accuracy of the strokes.
