This research aims to identify the effectiveness of the use of biomechanical curves on the development of start-ups for crawling swimming on the abdomen, the researcher used the descriptive method for the purpose of mechanical analysis based on the method of video analysis to start the race to crawl on the abdomen among individuals.

The sample of the research and the experimental approach with a single experimental group l followed by the pre-measurement Al-Baadi due to its suitability to the nature of the research, the research community was represented by the beginners of crawling swimming on the stomach in the Zamalek Club for Sports Games, and the number (15) young women for the training season 2019/2020 AD, the researcher selected the sample of the research in an intentional way, The number (8) young women, where each player performed 5 starting attempts that end when entering the water, the best 3 starting attempts were selected for each swimming, and the most important conclusions were the existence of statistically significant differences between the pre and post measurements in favor of the dimensional measurement of the same sample in the search of the biomechanical variables for a stage Starting race as a result of using qualitative exercises, and the results of the research showed a significant improvement statistically in some mechanical variables of the research sample due to the use of specific exercises, which led to the modification of the anatomical conditions of swimmers on the starting cube and achieving the best horizontal distance for a moment d Well water, the most important recommendations were guided by the values of variables Albyumkanikih averages reached at the start-up phase, whether the research sample or model indicators as a direct lead to the development of motor performance
