Predicting the Biomechanics Effects on the Human Arm of the Badminton Forehand Smash
並列摘要
In this paper, we investigate the kinematic and tensile variations in the upper extremities during the various phases of a badminton forehand smash movement, which if incorrectly performed may lead to sports injuries. Specifically, based on biological, kinematic, and dynamic concepts and principles, we develop a biomechanical model of arm swing paths whose feasibility is assessed using four types of motion paths: a correctly positioned badminton smash (Path 1), a smash recovery following a successful smash shot (Path 2), and two error motions that commonly occur during smash shots (Paths 3 and 4). We then conduct a motion analysis of these four paths to determine the kinetic chain of the forehand smash and the influence that stress and muscle strength exertion have on badminton players' arms. We find that Path 2 easily induces sport injuries in the humerus and biceps brachii; Path 3 causes serious sport injuries in the forearm (ulna and radius), wrist (carpal bones), triceps brachii, flexor carpi ulnaris, and extensor carpi; and Path 4 poses greater risk of injury to the forearm (ulna and radius), wrist (carpal bones), biceps brachii, and triceps brachii muscles. The proposed model can therefore be used to predict post-motion exertion points, making it a useful reference tool for training and teaching.
