THE EFFECT OF HIGH ــ INTENSITY INTERVAL TRAINING (HIIT) EXERCISES ON SOME PHYSIOLOGICAL INDICATORS IN YOUTH FUTSAL PLAYERS

Abstract

The research included four chapters. The first chapter contained the introduction and its importance in identifying training according to the high-intensity intermittent method (HIIT) in developing some physiological indicators, namely the maximum oxygen consumption and the level of metabolic rate before and after effort and specific oxygen endurance. The research problem is evident through the weakness in the physical capabilities needed by indoor soccer players and the training programs that do not meet the increasing requirements for these capabilities, which are reflected in one way or another in the adaptation occurring in the physiological indicators of the research. Therefore, the researchers used the experimental method for the experimental and control groups to suit the nature of the research. The research community was determined for the players of the Al-Kufa Sports Club for Youth in indoor soccer for the 2023 sports season, numbering (20) players. The research sample was selected at a rate of (16) players and they were divided by the double numbering method at a rate of (8) players for each group, one experimental and the other control. Exercises were prepared and applied according to the high-intensity intermittent training method for a period of (6) weeks at a rate of (3) training units per week. The researchers concluded that training according to the method High-intensity intermittent training (HIIT) has been shown to improve metabolic rate and VO2MAX for index in futsal players.
