The study aimed to identify: - The relationship between some biomechanical variables for a distance of (50) meters when running (100) meters from the low start with the achievement of the sample The researchers used the descriptive approach to suit the nature of the research.

The research sample included (4) runners representing the University of Mosul team in the field and arena games for the effectiveness of (100) meters freestyle, and (4) video cameras were used with a speed of (60) images per second, a Japanese-made Nikon type, and the height of the camera lenses was ( 1 m) perpendicular to the jogging field in a distance of (10 m - 30 m - 50 m) and then from the jogging field, respectively as follows: Camera (1), after (4.5) meters to the right of the runner and cameras (4.3.2) and then from the runner and the running field with ( 8m) distributed at the end of the above-mentioned distances, in order to extract the biomechanical variables specific to each runner from the stage of sitting and starting at the low start for a distance of (50) meters.

(30 m) for a distance of (50 m) from the total race distance (100 m) and my agency: ACDsee Photo Manager 2011 02 Max Track 03 SPSS Statistical 04 (Kenova cutting) 05 Paint 06 Word (printing program.

The researchers found The length and frequency of the step is effective in improving the level of running, -0 especially when starting and sitting position (low start) and up to a running distance (50 .meters) from the total distance of the race The study showed that the variable of the gradual inclination angle of the trunk -4 when starting from a sitting position (low start) and up to a distance of 30 meters has an influential role on the rest of the research variables of momentum, kinetic energy and .speed To achieve the best achievement, it was necessary to increase the frequency of the step at -0 first, offset by a gradual increase in the length of the step, with attention to raising the gradual angle of inclination of the trunk along a distance of (10 m, 30 m, 50 m) from a race distance of .100 meters
