The effect of using compound exercises supported by the polar m430 device and accompanied by iron on developing explosive power and the performance of futsal players

The purpose of this paper is to develop compound exercises supported by the Polar m430 to develop the explosive power of players from the Karkh II Intermediate School Futsal Team in Baghdad, and to determine the effect of compound exercises supported by the Polar m430 to develop the explosive power of players from the Karkh II Intermediate School Futsal Team in Baghdad. The study adopted the experimental approach, where the research sample was selected from the players of the Karkh II Education Futsal Team at the intermediate level. The original study population included (70) players. After excluding goalkeepers and injured players, (13) players remained, representing (18.57%) of the total number of players. The sample was randomly divided into two groups: an experimental group and a control group. The first experimental group underwent a training program accompanied by nutritional supplements, while the control group followed the training program only without any additional supplements. The remaining participants were divided equally, with (4) players in each group to ensure the accuracy of the results One of the most important results reached by the researcher is that: Compound exercises supported by the Polar m430 device for the experimental group had a significant impact on improving the physical component (explosive power), and the necessity of allocating a Polar m430 device to each player to develop explosive power. One of the most important recommendations recommended by the researchers is that: Emphasize the importance of using monitoring devices to improve other physical aspects of training and select other nutritional supplements to be implemented in conjunction with physical and skill capabilities, and study their impact on the players.
