Comparative Biomechanical Characteristics of One-Arm Hang in Climbing for Beginners and Qualified Athletes

The aim of the study was to identify the basic kinematic characteristics of the one-arm hang in climbing for beginners and qualified climbers. The technique of the one-arm hang in climbing among 20 leading climbers of the World and Ukraine and 20 beginner male amateur climbers was analyzed. A qualified athlete participated in the demonstration of various models of the one-arm hang performance. By means of Kinovea software 0.8.15, the kinematic characteristics of two models of the technique were analyzed (model 1 for beginner athletes, model 2 for qualified athletes. Beginner athletes carry out the one-arm hang mainly due to the ligamentous apparatus of the joints of the shoulder girdle with minimal inclusion of muscles, which is dangerous due to the risk of trauma to the ligaments of the shoulder joint. Skilled athletes perform the one-arm hang with trunk and leg muscles included, which reduces the strain on the ligamentous apparatus and lowers the possibility of injury to the ligaments of the shoulder joint.
