The research aimed to develop a program using Pilate exercises and to know its effect on the following: 1- The effect of the proposed training program for Pilates training on some components of the body composition of the 400m runners and the digital level of the research sample. 3- The effect of the proposed training program for Pilates exercises on some biochemical variables among the members of the research sample. tatistical processors: - SMA. - Mediator. - standard deviation. Wilcoxon Test. - Coefficient of torsion.- Average ranks. - sig values. p – value. - Percentage improvement. -Suggested quality. Among the most important results: 1. Pilates exercises have a positive effect with statistically significant differences on some components of body composition (body fat percentage, fat cell mass, non-fat cell mass, body mass index, total body water mass) under investigation among the subjects of the research sample. 2. Pilates training has a positive effect, with statistically significant differences, at the numerical level of 400m enemy among the subjects of the research sample. 3. Pilates exercises have a positive effect on statistically significant differences on the variables indicating the biochemical variables among the individuals of the research sample. 4. The proposed training program using Pilates exercises resulted in improvement rates in some components of the body composition, biochemical variables and the digital level of the 400-meter race among the individuals of the research sample.
