The effect of specialized training using the HIIT method on some physical and physiological abilities of young football players in Wasit

Abstract

The importance of studying the effect of high-intensity interval training (HIIT) on the physical and physiological abilities of football players is highlighted, as it can provide a scientific basis for developing modern training programs and improving individual and team performance. The research aimed to identify the effect of HIIT exercises on some physical and physiological abilities of young football players. The researcher adopted the experimental method as the most suitable for the nature of the study, using a single experimental group design with pre- and post-tests. The research population consisted of young players from clubs in Al-Hay district participating in the governorate league for the 2024-2025 season. The research sample was selected using simple random sampling and consisted of players from Al-Hay club. The researcher concluded the following: High-intensity interval training (HIIT) contributed positively to the development of most physical abilities in football players, especially explosive power, speed-strength, and strength endurance, after a period of eight weeks of application. The use of HIIT training led to an improvement in some important physiological variables, particularly VO₂max and power. Anaerobic activity, while heart rate did not show any significant differences between the pre- and post-tests.
