The Effect of an Educational Program Using Assistive Devices According to Some Biomechanical Variables on Developing the Spike Skill Performance of Young Volleyball Players

Abstract

The spike skill is characterized as a complex skill that requires a high degree of integration between physical abilities (such as explosive power and neuromuscular coordination) and biomechanical variables (such as approach speed, takeoff angle, height of center of gravity, hitting arm speed, and angle of impact). Any disruption to these variables directly affects the efficiency, accuracy, and power of performance .Biomechanical analysis has become an essential tool for understanding and evaluating motor performance. It allows for the identification of strengths and weaknesses in skill performance by measuring the kinematic and mechanical variables associated with the skill. Furthermore, linking the results of biomechanical analysis with educational programs is a modern trend that contributes to raising the level of sports learning and training. Hence, the importance of designing modern educational programs based on biomechanical analysis and employing assistive devices scientifically, with the aim of improving the technical performance of the spike skill. Therefore, the research problem is defined by the following main question: Does an educational program using assistive devices based on certain biomechanical variables contribute to developing the performance of the spike skill in young volleyball players? The research sample consisted of 18 young players from Al-Hashemiya Sports Club for the 2024/2025 season. The researchers concluded that the training program using assistive devices based on biomechanical principles led to a clear and significant improvement in all biomechanical variables. Furthermore, the integration of these biomechanical variables resulted in an overall improvement in the performance of the spike skill.
