The Effect Of HIIT Exercises On Speed-Strength And Some Physiological And Skill Variables In Handball Players

Abstract

This paper examines the impacts of high-intensity interval training (HIIT) on speed-strength and a variety of physiological and skill-based variables in handball players. The main objective is to determine the effectiveness of this modality of training to enhance the performance measures that are directly applicable to the sport and give empirical data that may guide coaches and experts in the development of more effective and sport-specific training programs. The research question will be in the following form: What would be the effect of high-intensity interval training (HIIT) on improving speed-strength and other physiological and skill-related parameters in handball players? The study objectives were to construct HIIT exercises that were specifically aimed at enhancing the speed -strength and other physiological and skills-based traits relevant to handball. The general objective was to determine the impact of HIIT on these parameters. A quantitative experimental research design was selected, which included an experimental group, and a control group which was considered the best way of tackling the research problem. The sample was comprised of 16 participants who were members of the handball team of Maysan Education Directorate. The total population was divided into a random sample of 12 players, six players were selected in each study group; experimental and control group. Two players were also not included in the study due to being goalkeepers and two other players were dropped out of the experimental group. Statistical tests were done by means of SPSS 26. The results show that the applied HIIT programmed improved the speed-strength of the participants that signifies increased efficiency of the fast-twitch muscle fibers. In addition, the training intervention programs produced a tremendous gain in maximal aerobic capacity (VO₂ MAX), thus enhancing the athletes to maintain intense and repetitive workload in the competition. The recommendations of these results are that HIIT should be included in the physical preparation programs of handball practitioners, and a keen focus on increment of levels of intensity and duration is required to suit the requirements of the sport. Slow progression of this nature is necessary to ensure physiological adaptation with minimal risk of fatigue or injury.
