The effect of water aerobic training on some anthropometric and skill variables and their relationship to the digital level of the 400m freestyle swimmer for juniors.

Abstract

Training within the water environment is necessary and extremely important, which swimmers need in developing digital levels to achieve the best achievements in tournaments. and international The research problem included studying the effect of water aerobic training on some anthropometric and skill variables and their relationship to the digital level of the 400m freestyle swimmer. Free for juniors and the extent of its relationship to the digital level, and several hypotheses have been developed for research, including the presence of statistically significant differences between the tribal and remote measurements for each of the experimental and control groups in the anthropometric and skill variables under research in favor of the dimensional measurement .The researcher also assumed that there were statistically significant differences between the two dimensional measurements of the experimental and control groups in the anthropometric and skill variables in favor of the dimensional measurement of the experimental group. The research sample consisted of 20 swimmers from City Club Sports Club, and they were divided into two groups by intentional method, each group 10 swimmers, and their age in the age group was 14 years, and homogeneity was made between individuals The sample in the growth, anthropometric, skill and digital variables is 400m free, and therefore a water aerobic program was designed, which included 40 training units, 5 training units per week, and the intensity of the exercises ranged from 50-80% and included exercises with body weights and free weights in the water medium. After completing the training program, a post-measurement was conducted for each of the two groups, and the data was processed statistically using the arithmetic mean, standard deviation, and the test of significance of differences (T), improvement rates and Pearson correlation coefficient, and the results indicated that the water aerobic exercises led to some improvement Anthropometric and skill variables, and the results also showed an improvement in the digital level of the 400m freestyle
