The Effect of (Stairs, Gravity) Exercises in Developing Some Physical Abilities of the Muscles of the Legs and Improving the Achievement of the Long Jump Competition for Youth

The study aimed to prepare exercises (stairs, weight) to develop the physical abilities of the muscles of the legs and to know the impact of the exercises in improving the achievement of the long jump competition for young people, during which the researchers used the experimental approach (and by designing the two equal experimental groups with pre and posttests) to suit the nature of the problem and reach the achievement of the research goals. After the research community identified the young players for the long jump competition, whose ages ranged between (18-19) years, they were divided for the purposes of the search experience by (4) players for each of the first experimental (ladders) and the second experimental (gravity) research groups and each player was given (3) Attempts with a total of (12) attempts per group and they represent the young players for the long jump competition in the provinces of the Middle Euphrates. After completing the testing and measurement process for the research variables, the results of the research were extracted after statistical treatment. Including the researchers reached several conclusions, the most important of which were the following:
