Abstract

This study aimed at exploring the key kinetic and kinematic factors of 110-m hurdle clearance performance using three-dimensional (3D) analysis system. Ten national level athletes participated in this study. The kinematic analysis of the hurdling sequences was recorded using ten mutually synchronized digital cameras. Body markers were digitized using SkillSpector ® software. Ground-reaction force was calculated by using rigid body inverse dynamics using the Smith's equations. All variables were combined into components through a principal component analysis. The retained components have been used in a multiple regression analysis. Twenty variables were retained as key hurdling performance determinants. Specifically, the horizontal and vertical velocity of the centre of mass (COM) and the lead-leg/trail-leg in all phases (i.e., take-off, flight, and landing), horizontal and vertical displacement of the COM, the lead-leg/trail-leg vertical displacement, and the flight-time at clearance are among the main hurdling performance determinants. Overall, to improve hurdling performance, greater horizontal velocity, lower vertical displacement at flight and lower contact-time at the takeoff phases through a higher rate of force development are needed.

The Effects of Motionless Interventions Based on Visual-Auditory Instructions With Sonification on Learning a Rhythmic Motor Skill

“…To calculate the spatial and relative timing errors of the angular displacement of the leading leg's knee, we analyzed the participants' movements, based on the following main three phases (Amara et al, 2019;Čoh et al, 2020):…”

“…However, the transfer of this type of auditory information in hurdling is limited to the times when feet touched the ground. The complexity of hurdling is related to the precise performance of lower body movements that are timed with jumping over the hurdle (Amara et al, 2019;Brničević, 2020). For this reason, more complex movement sonification can be an effective complement to visual modeling in acquisition of this specific skill.…”

Efficiency factors in 110-metre hurdle clearance techniques: kinematics among specialist hurdlers and decathletes

“…over the years, there has been a considerable amount of biomechanical literature concerning the kinematic analysis of hurdle clearance at Human Movement, Vol. 25, No 1, 2024 different levels of performance in both male and female athletes [2,[7][8][9][10][11][12]. However, there is a scarcity of data that compares the distinct movement characteristics exhibited by elite hurdlers in contrast to elite athletes participating in combined events.…”
