The effect of training with barriers at different heights on some biomechanical variables of the back row attack in advanced volleyball players

Abstract

Volleyball is one of the most successful and competitive sports worldwide, characterized by excitement due to its skillful motor sequences. Therefore, a volleyball player must possess the appropriate physical and motor qualities required for the game to perform skillfully. The aim of the research was to prepare training with varying heights of barriers (30 cm, 50 cm, 70 cm) and to identify the impact of these trainings on some biomechanical variables of the spike from the back row for advanced volleyball players. The hypothesis of the research is that there are statistically significant differences between the pre-test and post-test in some biomechanical variables of the spike from the back row. To achieve the research objectives, the researcher used the experimental method with a one-group design featuring pre-test and post-test. The experiment was applied to the experimental group, which consisted of (8) players from the Hebheb Club in Diyala Governorate. The experiment confirmed the research hypotheses, leading to positive results.
