The 400-meter hurdles is considered one of the most complex track and field events, requiring athletes to possess a high level of speed endurance, anaerobic functional capacity, and the ability to accurately control stride rhythm throughout the race distance. A total of 24 young hurdlers participated in the pedagogical experiment and were equally divided into a control group (CG, n=12) and an experimental group (EG, n=12). In the control group, training sessions were conducted according to the traditional existing program, whereas in the experimental group, training was based on a specialized block of technical exercises developed by the author, aimed at improving kinetic differentiation, optimizing the ratio of stride frequency and stride length, and maintaining stable stride structure between hurdles. At the end of the experiment, it was found that the EG athletes demonstrated statistically significant improvements (p < 0.05 and p < 0.01) compared to the CG in hurdle clearance time, inter-hurdle running performance, stride rhythm stability coefficient (SRC), and final 400-meter race results. Indicators of neuromuscular adaptation and biomechanical coordination confirmed the high effectiveness of the proposed methodology in the training of young hurdlers. Keywords: hurdle running, 400-meter distance, stride rhythm stability, specialized technical exercises, biomechanical efficiency, speed endurance, coordination, anaerobic capacity, neuromuscular adaptation, pedagogical experiment.
