Reaching the highest levels is one of the important matters that requires knowledge of the variables that contribute to mastering the skill of shooting in its high style, and knowing the precise details of them and their causes will contribute in a significant and effective way to the performance with an economy and a better accuracy index, and among these variables is the electrical activity of the most important muscles working in performance and an accuracy index. Correction, the aim of the study was to reveal (the relationship between the electrical activity of the most important muscles working with the accuracy index to shoot from the forward jump for handball players). The research community, which numbered (3) players, where each player was given three attempts for each method. The researcher used each of the electrical activity variables for the most important muscles working during the performance of shooting using the EMG system. Eight muscles were identified, distributed to the upper and lower ends of the body, and the maximum study was done. Electrical activity of the muscle.
The researcher reached the following conclusions:
‒ The levels of the electrical signal to the muscle vary during the performance stages according to the requirements and nature of the stage.
‒ No increase in the level of electrical activity of the working muscles under study was recorded for all cases of the increase in muscle mass and the accompanying increase in the level of strength, and this appeared in the correction stage of some working muscles.
The researcher recommended the necessity of using the EMG device to know the electrical activity of the working muscles for each skill of handball, and its use of the muscles as one of the most important means in determining the areas of strength and weakness of handball players. Hand.
