The effect of suspended weight exercises on the development of muscular efficiency, dynamic and static balance, selected biomechanical variables, and performance achievement in advanced discus throwers

Abstract

     The aim of the research was to identify the effect of exercises using suspended weights on the development of stabilizing muscle function and its reflection on selected biomechanical variables and performance achievement in advanced discus throwers. The researcher adopted the experimental method using a two-group design with pre- and post-tests. The research population consisted of the top eight advanced discus throwers in the Iraqi Championship, while the sample was selected purposively in accordance with the nature of the study. The training program included specific exercises using suspended weights, implemented over a period of eight weeks at a frequency of three training units per week, with the aim of increasing the demands of dynamic stability and trunk control during technical performance. The research tools comprised a set of tests related to performance achievement and dynamic balance (static and dynamic), in addition to the analysis of selected biomechanical variables and digital performance. The results were analyzed using appropriate statistical methods. The findings revealed statistically significant differences between the pre- and post-tests in favor of the post-test across all studied variables, indicating the effectiveness of suspended weight training in improving the function of stabilizing muscles, enhancing movement stability, and improving the biomechanical efficiency of performance, which positively reflected on the level of achievement in discus throwing. Accordingly, the researcher recommended incorporating this type of training into the training programs of discus throwers.
