The effect of special exercises according to the biomechanical indicators in improving the explosive power and rotational movements of gymnasts and juniors on the horse handles

The horse device with handles for men is one of the most difficult devices for players, which requires special skill and strength, specifically in rotation movements, that strength exercises, especially according to biomechanical indicators, are part of studies that focus on analyzing movement under specific mechanical conditions, which contributes to understanding the internal and external forces affecting the movement and its conditions, and the importance of research in organizing training lies in the selection of certain exercises for specific periods of time, while ensuring the achievement of the objectives of the exercise. As for the problem of the research, there is a gap between the performance of our local players compared to the world champions did not live up to the level of ambition, especially in the device of the horse handles, which requires an ideal balance between strength and skill and accurate biomechanical control in the movements of the body, so he worked on the use of strength exercises, especially according to the biomechanical indicators in improving explosive power and weighted movements and used the experimental approach in the manner of two equal groups on a sample of players (5) players and conduct the tribal test and use strength exercises, especially according to the indicators Biomechanical The application of special exercises took eight weeks, at a rate of (2) training units per week .
