Abstract: The last period witnessed a great development in all sports games and events as a result of studies and research in various sciences that are in the interest of sports achievement, including the free running event (100m), which is one of the activities of the enemy that witnessed a great development in the level of technical, physical, psychological and other aspects, which led to Achieve new numbers that could not have been registered before this period. The requirement to reach the highest levels of the effectiveness of a sprint (100 meters) is free to impose on the trainers and workers on this event to find new and modern training methods that would accelerate the process of raising the level of the player and add a new training environment that would create a situation similar to the actual performance with training conditions that impose training burdens on the runner. New or different from the one that was previously trained in, thus moving away from what is ineffective and reaching positive results in the training process. It is noticeable that there is a wide range of aids in training athletes athletes and according to the type of activity practiced by the athlete, as we notice, for example, that short distance runners use the withdrawal of certain weights attached to the runner’s body for the purpose of developing the element of strength characterized by speed and the use of iron shirts with high weight and weights Legged and others. As the equipment and training auxiliary means are the focus of attention of many workers in the training field because of their importance and a great role in accelerating the process of development and integration in the physical and skill aspects of the athlete to bring him to higher levels, and that these devices, means and tools have their own goals, including what goes into the process Correcting the movement paths, including what is included in the physical aspects, including what combines the two by facilitating the performance and isolating extraneous movements and contractions that would negatively affect and thus delay the achievement of the ideal level for the player. Through the observation and experience of researchers, it was found that there is a lack of use of modern scientific devices, tools and means that have a positive impact in raising the level of sports performance and achieving the required achievement, and the trainers ’dependence on some traditional training tools and their lack of modern techniques in the training process that contribute and help the athlete in raising his level of All aspects (physical, skill, and psychological) as well as economics with time, effort and financial resources to achieve good results, hence the importance of research in manufacturing a training device with different training resistances that can be controlled according to the type of exercise and intensity required for training, and its use is similar to the ideal enemy method and style and by applying a variable pull resistance It would help the sprinter to reach the higher levels by developing explosive power and velocity required for a free running (100m) sprint. The study aims to manufacture a training device aimed at developing explosive power, speed, and achievement for runners with an enemy activity (100 meters) free youth, and to prepare exercises using the factory training device to develop explosive power and speed and the achievement and achievement of enemy runners (100 meters) free youth. Identifying the effect of exercises using the manufactured device in developing explosive power and speed, and the achievement of runners with the effectiveness of (100 meters) free youth .. The researchers also assume that the manufactured training apparatus has a positive effect on the physical abilities under investigation and the achievement of the activity of the enemy (100 meters) free for the members of the research sample, and also the researchers assume that there are significant differences between the pre and post tests in explosive strength and speed and the achievement of the running effectiveness (100 meters) free youth For the post test.
