A comparative analytical study of some biomechanical indicators between abduction and track start For young swimmers The research aims to compare three modes of different starting positions) grab start-track start with wedge-track star without wedge (and therefore to identify the best starting method that must be followed with young swimmers, the researchers used the descriptive survey method , and A sample of swimmers from the Al Ahli Bank Club, age group 11 and 12 years registered with the Egyptian Swimming Federation, was selected with a number of 10 swimmers, and they were deliberately selected from the best two-stage swimmers according to their results in the national championship in Alexandria for the 2019 season, The camera was filmed in the Olympic pool of the Al Ahli Bank Club ,The results revealed that there are statistically significant differences in some biomechanical indicators in my two moments (the moment of the start of the start of the start of the start after the relative dormancy on the starting cube - the moment of maximum bending of the knee joint) in favor of starting the track start with block's back plate and the moments (the moment of the start of pushing with the legs - the moment of the end Contacting the starting cube - the moment of the start of flight - and the moment of the beginning of contact with the surface of the water) in favor of the quick start, and one of the most important conclusions reached by the researchers and recommend to the trainers is the importance of training for the grab start at the beginning of training for the young junior stages of his ease and the ability to push the two men together and then after that Training on track start on the newly created cube (OBS11) to take advantage of without block's back wedge for performance.
