The Effectiveness of Retaliatory Force Exercises in Developing the Explosive Power of Two Legs and Arms and the Accuracy of the Spike in the Badminton of Young Players Under the Age of 18 Year

The problem of research is that most young players with badminton do not have sufficient muscular strength for the muscles of legs who have a big role in the accuracy of the strike. This was observed through the personal experience of the two former players and interested in badminton and through the interviews that were conducted with Most trainers of the youth category and through the belief of researchers in scientific research as the correct scientific step to solve problems, exercises were designed to refine the explosive capacity of the muscles of the two legs and their impact on improving the accuracy of the strike in the field of badminton for young players 18 years old .

Research aim to prepare exercises regressive force to develop explosive power in the muscles of legs, arms and accuracy spike in the badminton players for young people under 18 years old. The researchers used the pilot approach to experimental design with pre-test and post-test for the two groups (experimental and control) to suit the nature of the research. The research community was determined by the players of the Mahaweel Sports Club with ages (16-18) for the training season 2018-2019 of 14 players. The sample was selected in a comprehensive inventory method and the sample was divided into two groups (experimental and control) with seven players per group. One of the most important conclusions was the positive effect on the development of explosive force of arms and legs using the reactive power exercises of the experimental group and all tests. The reason for the development of the experimental group was the result of the independent variable use of aftershocks for the development of explosive force of the arms and legs, Develop the skills of the precision of the spike in the badminton.
