The research aims to identify the effect of training the effect of 3/7 training on developing the maximum anaerobic capacity and the digital level of the 100-meter race. The experimental method was used, and the research sample was selected intentionally from the runners of the Zagazig University team and the Faculty of Physical Education for Boys for short distances during the academic year (2021/2022 AD).The research sample was selected intentionally from the research community of those who have the best times in the 100-meter race. Their number is (6) runners as one experimental group using the significance of the differences between the pre- and post-measurement. The 3-7 training was applied to the experimental research sample and during the special preparation period for a period of (8) weeks at a rate of 3 weekly training units. After completing the application of the training program, post-measurements were conducted to identify the effect of the 3-7 training on the rotation of the maximum anaerobic capacity and the digital level under investigation. The most important conclusions were that the 3-7 training contributed to the development of some special physical abilities, maximum anaerobic capacity and the numerical level of the 100-meter race under study. The most important recommendations were to rely on the 3/7 training in developing special physical abilities in various track and field competitions for many age groups, to use the 3/7 training in developing special athletic performance and physiological and biomechanical variables in track and field competitions, and to conduct more scientific studies and research on how to include the 3/7 training within resistance training programs with the aim of developing physical abilities and athletic performance.
