Methodology for improving technique in the first phase of the 100-m race

The objective is to design a methodology for the improvement of the technique in the first phase of the 100m flat race in juvenile sprinters; Materials and Methods; quantitative and qualitative approach, documentary analysis, non-participatory scientific observation, survey, interview, expert and user criteria, methodological triangulation as a procedure for the recruitment of information, from different methods, techniques for biomechanical analysis, statistical methods and/or mathematical processing, frequency, mean and variability coefficient, and non-parametric Wilcoxon test; Results: the design of a methodology was achieved which, with its implementation, allowed for the improvement of the first phase of the 100m flat race of the juvenile runners; Discussion, which allows for the existence of an improvement in the improvement of the technique of the first phase of the 100m flat race of the athletes studied; Conclusions, the implementation of the methodology allowed for the improvement of the technique of the first phase of the 100m flat race for juvenile sprinters, in accordance with the spatial kinematic characteristics that model it and the characteristics of the competitive activity of this test
