The impact of Gibala-style workouts on runners under 20 years old's 200-meter performance and speed endurance according to energy index

Abstract

The importance of the research is reflected in the study of the effect of exercises in the Jibala style according to the kinetic energy index of the performance stages in endurance of speed and achievement of 200 meters for runners under 20 years. As for the research problem: by following up and informing the researchers of the exercises of runners under 20 years old, they noticed that most of the trainers rely on commonly applied training methods and methods and their lack of use of modern training methods, including the Jebala method, which is one of the modern training methods that have occurred recently and which uses training in a short time. This is consistent with the nature and characteristics of the game, thus improving performance under the conditions of extreme work and raising the physical level of the runners. It also increases the excitement and suspense of the runners. Through the above, the research problem can be summarized in the following question:Does the use of Gibala-style exercises according to the kinetic energy index of the performance stages have a positive effect on endurance of speed and achievement of 200 meters for runners under 20 years? The research aimed at: Preparing Gibala-style exercises according to the kinetic energy index for the 200-meter performance stages, as well as identifying the effect of Gibala-style exercises for the performance stages on the endurance of speed and completion of 200 meters for runners under 20 years.
