The percentage of contribution of the training process scale for coaches to the explosive power of the high smash skill for advanced volleyball players

الملخص

The purpose of this study was to explain the contribution of the training process level scale to the explosive power of the high spike skill in volleyball and to enhance and standardize a training process scale for volleyball coaches from the perspective of their players. The researcher used the illustrative survey method and correlational analysis  as these were suitable for the research problem. The research population was described as the players of the Iraqi Elite Volleyball League in the 2024-2025 season, totaling (13) clubs (Peshmerga, Police, South Gas, Industry, Habbaniyah, Hit, Erbil, Nu'maniyah, Northern Refineries, Dagharah, Muqdadiyah, Nineveh, and Haditha), with a total of (158) players. The researcher picked the sample from the whole  population, resulting in a total sample size of (145), representing (91.77%) of the original population. Thirteen players could not be reached or were therefore excluded. The sample was divided into (8) players for a pilot study, illustrating (Industry Club). (50) players were selected to develop and determine the scientific basis for a training process level scale. Subsequently, (62) players were chosen for the standardization sample, and (25) players were selected for the main experimental sample. The findings of the relationship and contribution percentage between the training process level scale and explosive skill power were presented and discussed. The researcher attained many conclusions: the scale demonstrates the level of the coach's training process and to develop performance accurate assessment of the training process demands continuous knowledge of the components of the training situation, identifying training needs, designing the training program, implementing the training and finally evaluating the training program. Explosive power plays a important role in the success of the volleyball spike skill.
