Exercises using the verti max device and its impact on developing endurance, the special strength of the throwing arm and the achievement of javelin throwing for players under 16 years old

Abstract

The importance of the research lies in benefiting from special exercises to help the use of any training device such as the use of the (Vertimax) device, as these exercises help in developing special endurance according to the development of physical abilities using this device, and from here the research problem emerged that it is important for the player to work on the levers The body to get better performance in the shooting process and to get the best achievement for this activity by using a new training device that puts multiple resistances at the same time on all the muscles working in the performance of this activity, as these exercises can be a complement to the rest of the exercises in influencing the development of the physical side of the shooters Spear and can contribute to the progress of achievement in this game at a high level ,The aim of the research was to identify the effect of exercises on the device (Vertimax) in developing some of the special endurance of the throwing arm and the achievement of javelin throwing for players under 16 years of age. The research hypothesized that there are statistically significant differences between the pre and post tests in the endurance of the arm aiming for the research group. The research sample included the intended intentional method, and the sample was the original research community of (6) javelin throwers and their ages were under 16 years old. In conclusion, the two researchers concluded that there was a significant development in the endurance levels of the aiming arm as a result of training on the Vertimax device. The two researchers recommended the necessity of using devices and auxiliary tools in the training process, such as the Vertimax device, and emphasizing the use of modern techniques that would reflect real indicators and standards for strength variables, which give an indication of the level of development in training
