This article considers the characteristics of effectiveness of technical fitness of BMX cyclists in performance of hurdling. The investigation included two types of tasks: horizontal straight acceleration (on flat surface) and hurdle passing ("double" and "rhythmic section"). Subjects were 33 cyclists of different qualifications with body mass 51.06±16.436 kg, body length 1.599±0.1503 m, aged 12.7±3.52 years. Regression equation was y = 0.96625 * x - 0.4592 (averaged for "double" and "rhythmic section"). Methodology was based on Modification of integrative approach to the study and evaluation of movement action technique in pedagogical investigations. Measuring performed using optronic pairs (MuscleLab) and 3D kinematical and dynamical analysis (Qualisys & AMTI). Average velocity of passing of "double" was 7.261±1.2261 m/s, for "rhythmic section" it was 7.317±1.1877 m/s. Parameters of effective technique of hurdle passing in BMX-Racing were found. The control of dynamical characteristics of hurdling in BMX-Racing is recommended.
