There is no doubt that every sports game has characteristics that characterize it and goals that it works to achieve through training, testing and measurement to achieve these goals. The fact that the sport of wrestling requires a great effort that does not stop when learning its tactics. Testing and measurement are important things that a wrestler needs and the coach needs to know their true level in order to develop their capabilities and draw the training map accordingly, and since the par terre defense for the gut wrench hold from requires maximal physical effort, especially on the arm, to resist the competitor`s attempt to break the moment of inertia of the wrestler, who in turn tries to increase the force imposed on the mat by the palm, it can be useful to measure this force. For this reason, the descriptive approach was used in the survey method, and the research community included the wrestlers of the Iraqi national team for Greco roman wrestling for senior for the year 2021-2022 in Al-Qadisiyah Governorate in Iraq, which numbered (8) wrestlers. The mean and the standard deviation of the body mass was (54 ±5.50) and preparations were made to design the test of the maximum arm resistance to counter the gut wrench hold in Greco roman wrestling for men, following a review the studies and discussing with experts and specialists in this matter. Test name: The Maximum arm resistance to the gut wrench hold in Greco roman wrestling Purpose of the test: To measure the maximum resistance of the arm to the gut wrench hold Tools used: the factory electronic palm, iPad or mobile device, straps. Description of the performance: The wrestler rises from a defensive position with him wearing the electronic palm manufactured with his hand resting on it and the palm of the palm containing sensors that measure the weight imposed on the mat. At the top of the palm there is an electronic screen that gives us a reading of the weight imposed and the competitor wrestler tries to press the upper arm trying to spin (Wrap the wrestler to score a point, and the electronic palm device can be linked to the (Koko international) program, which can be installed on smart mobile devices and iPads via (Bluetooth) to synchronize reading the screen in the palm with the program on the mobile to facilitate reading the maximum resistance. Recording: Recording the highest reading a wrestler reaches in kilograms. As for the most important conclusions reached by the researchers: The maximum test gives us a real reading of the resistance placed on the mat by the wrestler while resisting the gut wrench. The reading corresponds 100% between reading the screen on the top of the palm and the reading in the (Koko International) program located in the mobile or iPad. Recommendations: • The test can be used to give quantitative values of the gut wrench hold resistance of wrestlers in seasonal tests. • The quantitative values extracted from the test can be used in building training programs according to individual differences.
