Abstract
Biomechanical Model of Hurdle Clearance in 100m Hurdle Races: A Case Study
Highlights
The biomechanical model of hurdle clearance for the 100-m hurdle race is based on the technique of the Australian athlete Sally Pearson, one of the world’s greatest runners of 100-m hurdle events
According to the results of the biomechanical analysis (Table 1, Figure 1), the athlete had an average velocity of 8.58 m/s at the clearance of the sixth hurdle
In the case of Sally Pearson, the horizontal velocity of the center of mass (CM) after hurdle clearance was 8.38 m/s, which means that when the hurdle was cleared, the velocity was decreased by 0.13 m / s (1.5%)
Summary
The biomechanical model of hurdle clearance for the 100-m hurdle race is based on the technique of the Australian athlete Sally Pearson, one of the world’s greatest runners of 100-m hurdle events. She holds many other top achievements such as the gold medal at the Daegu World Championship in 2011, the gold medal at the 2017 World Championships in London, the silver medal at the 2008 Beijing Olympics, and the silver medal at the 2013 World Championship in Moscow Her personal record for the 100-m hurdle event is 12.28 seconds, which is the sixth fastest time in the history of the event. The loss of horizontal velocity must be kept to a minimum This ability depends on a number of factors, especially those that define the takeoff before the hurdle, the trajectory of the movement of the CM (CM = center of mass) and the landing after the barrier (Kampmiller, Slamka, & Vanderka, 1999; Amritpal & Shamsher, 2015).
