The purpose of this paper is to preparing complex exercises (physical, physiological) using the Polar m430 to develop the explosive power of players from the Karkh II Education Team, preparatory stage, futsal team in Baghdad, exploring the effect of complex exercises (physical, physiological) using the Polar m430 to develop the explosive power of players from the Karkh II Education Team, preparatory stage, futsal team in Baghdad, and exploring the effect of iron supplementation (hemoglobin) on the biochemical research variable. The study was conducted using the experimental approach by the researchers. The research population consisted of (12) players from the Karkh II Intermediate School Futsal Team, out of (72) players, after subtracting goalkeepers and injured players. The total number of players was (8). This indicates that the proportion of the research population to the original population was (9%). Two groups were randomly selected a control group and an experimental group—using a randomized method. The first experimental group was given the curriculum and nutritional supplements, while the second group was subjected to the training curriculum only. The remaining participants were divided. (4) players were assigned to the experimental group and (4) players to the control group. One of the most important results reached by the researcher is that: Compound exercises (physiological and physical) based on Polar m430 readings for the experimental group had a significant impact on improving the physical component (explosive power), and it is essential that each player use a Polar m430 dedicated to them in order to develop explosive power. One of the most important recommendations recommended by the researchers is that: Emphasize the need to use monitoring devices to improve other physical aspects of their training, and select other nutritional supplements to work with physical and skill capabilities and determine the extent to which these are affected by the supplements used.
