The effect of exercises (weights, rubber ropes) on the development of physical abilities, movement and improvement of achievement in swimming (50) m freestyle for youth
The study aimed to prepare exercises (weights, rubber ropes) in developing the physical and mobility abilities of young swimmers and improving their achievement in swimming (50) meters freestyle. For achieving this aim the researchers use the experimental procedure (equipotent groups) to fit the problem, and the research identifies the youth swimmers for (50) m freestyle in the clubs of Najaf who are (8) swimmers. For the purposes of the research experiment, (6) swimmers were randomly selected, and by (3) swimmers for each of the first experimental research groups (weights) and the second experimental (rubber ropes). Each swimmer has 7 attempts and a total of (21) attempts for each group, and after completing the tests process for the research variables, which is extracting the results and treating them statistically, from which the researchers reached some conclusions, including: 1- Both weight training and rubber ropes positively affected the development of physical and movement abilities and achievement in the 50 m freestyle swimming for young swimmers. 2- Weight training came with the best influence in developing the explosive ability of the two legs, and the least improvement in the rubber rope exercises. 3- The rubber rope exercises showed a preference in impact to develop (the strength distinguished by the speed of the two legs, and the distinctive strength of the speed of the arms, agility) and to improve the achievement of youth in swimming (50) meters freestyle compared to their achievement with weight training.
