Players&#39; ability to shoot accurately and swiftly while stationary makes upper limb reaction time crucial for success.<br> <strong>Objectives.</strong> The research objective is to investigate the relationship between the motor time of the arm muscles and the accuracy index of shooting from a stationary position in fourth-stage handball players.<br> <strong>Methods. </strong>The researchers employed the descriptive method because it is a commonly used method in research on a sample of students from the fourth stage of the College of Physical Education and Sports Sciences. The sample consisted of 29 male students from the community of origin and 43 students.<br> <strong>Results.</strong> It is showed that the variables under study have significant direct correlations with the accuracy variable of shooting from stability, where the correlation of the motor response time was r=0.73 (p=0.047), the speed of movement of the arm r=0.87 (p=0.380), the maximum decrease in the knee angle variable r=0.77 (p=0.360) and the maximum decrease in the center of mass of the body was r=0.79 (p=0.380). In contrast, the degree of elbow angle during the ball&#39;s exit was variable, r=0.62 (p=0.560), and the degree of wrist angle during the ball&#39;s exit was variable, r=0.79 (p=0.380).<br> <strong>Conclusion. </strong>The study found that motor response speed, knee angle, and body center of mass have a significant impact on skill accuracy. These factors balance the player and maintain the movement path, resulting in an integrated skill. The accuracy of shooting from consistency in handball is primarily determined by the angle taken at each stage, particularly during the exit phase of the ball.</div> Response Time, Biomechanics Phenomena, Motor Skills, Sports Performance 0 0 http://aassjournal.com/browse.php?a_code=A-11-2205-6&slc_lang=en&sid=1 Abbas Hussein Khalifa abbas.h@cope.uobaghdad.edu.iq 100319475328460017500 0009-0002-9758-7540 No College of Physical Education and Sports Sciences, University of Baghdad, Baghdad, Iraq Mustafa Ahmed Obaid mostafa.a@cope.uobaghdad.edu.iq 100319475328460017501 100319475328460017501 Yes College of Physical Education and Sports Sciences, University of Baghdad, Baghdad, Iraq Zahraa Adnan Hadi 100319475328460017502 0009-0004-4383-2728 No College of Physical Education and Sports Sciences, University of Baghdad, Baghdad, Iraq
