Objective of the study. To compare the main spatiotemporal and angular parameters of the technique of elite hurdlers (men and women)
Methods and structure of the study. This article analyzes the spatiotemporal and angular characteristics of running technique and hurdling by the finalists of  the World Championships 2017 (London) in  110 m hurdles (man) and 100 m hurdles (women). The study used data from the IAAF Biomechanical Reports   and Statgraphics plus 5.0 for data processing.
Results and conclusions. The research shows that in the hurdle clearance phase statistically significant differences are  observed between men and women in the take-off and landing distances and the hurdle flight time. While running between hurdles, the length and flight time of the first step in women is greater (p<0,001), and the length of the second step is shorter (p<0,05).  The trunk-thigh angle at toe-off during the take-off phase  and the lead leg knee angle at touchdown in the two groups also differ (p<0,05).  Many of the studied parameters have a significant range of values: in women, the lead leg knee angle (53-90°) and  the trail leg knee angle (141-173°) during the take-off phase, the trunk angle at touchdown (48-64°) and toe-off during the landing step (63-78°); in men - the trunk-thigh angle during the take-off phase (53-82°) and the lead leg knee angle at touchdown (150-177°).

Keywords: hurdling technique, biomechanical analysis, short hurdle events.
