The effect of anaerobic exercises in terms of performance tolerance in the concentration of enzyme (P.F.K) for futsal players

Abstract

The study aimed to identify the effect of anaerobic exercises in terms of anaerobic performance endurance test in the results of the pre- and post-tests of the control and experimental research groups in the concentration of phosphofructokinase enzyme for futsal players, and the effect of anaerobic exercises in terms of anaerobic performance endurance test in the results of the post-test of the control and experimental research groups in  the concentration of phosphofructokinases enzyme for futsal players The researchers used the experimental approach by designing the two equivalent groups (control and experimental) with tight control, for its suitability to the nature of the research problem, and the research community was determined by the players of Al-Alam Futsal Club applying for the sports season (2024-2025), who numbered (16) players, while the research sample was chosen in a deliberate way and consisted of (12) players representing (75%) of the research community, and the researchers conducted their training curriculum on the sample for a period of (8) weeks, after which he processed the data obtained from the pre-tests. Through a number of statistical methods by the statistical program (SPSS), the researchers reached a number of conclusions, the most important of which is that biochemical measurements recorded an increase in the effectiveness of  the enzyme P.F.K after the application of the training program, which indicates an increase in the efficiency of anaerobic energy representation (glycolysis).
