Problem: In the World Athletics Championships, the racewalkers participate with the highest level of technical execution and with the best physical conditions, so the analysis of the steps of a racewalker is key to obtain an optimal result. Objective: To analyze the technique of an elite racewalker and the behavior of the variables of the athletic racewalking, pre-competition to the World Athletics Championships. Method: A test on an electronic track was given to one athlete, evaluating the kinematic variables: step length, step frequency, flight time, and speed. ANOVA was used to determine significant differences (p ≤0.05). Result: In the three tests carried out, all the variables increased significantly, although the most significant difference was found between flight time and step frequency p = 0.0000001, p <0.05. Conclusion: Since the flight time increases rapidly, it must be careful that this not influence the technical execution of the racewalkers, to be more effective, and thus avoid a warning or disqualification.
