Research Objective: To take advantage of HIIT workout for neuro-muscular efficiency and blocking abilities of volleyball players. To evaluate the effectiveness of HIIT training in the development of neuromuscular efficiency and blocking skill in volleyball players. The experimental approach was chosen because it was the most suitable method for the research problem. The population, specifically advanced volleyball players, was intentionally selected using a list of sports clubs in Diyala Governorate, and the population is divided into four clubs. The principal sample used for the study was randomly selected through a lottery method. It was made up of players from the Khanaqin Sports Club, and Al-Wajihiya Sports Club. The sample was separated into experimental and control groups. Players of the Khanaqin Sports Club are the experimental group, numbering 18 players while players of the Al-Wajihiya Sports Club are the control group, numbering 14 players. The results of the study showed statistically significant differences in the level of neuromuscular efficiency between the experimental and control groups. The differences favored the experimental group that underwent HIIT training, demonstrating the effectiveness of this type of training in stimulating neuromuscular adaptations in volleyball players. Furthermore, HIIT training has a qualitative impact on developing specific motor abilities that require rapid response, explosive strength, and precise neuromuscular coordination. The researcher recommends the necessity of adopting high-intensity intermittent training (HIIT) within the training programs directed at age groups in volleyball, due to its positive impact in enhancing neuromuscular efficiency and improving skill performance, especially in vital defensive skills such as blocking, and encouraging coaches of sports clubs in Diyala Governorate and others to employ HIIT training according to scientific foundations (in terms of intensity, repetition, and rest periods) in a manner that is compatible with the level of players and their physical conditions, to achieve the best training results.
