Abstract

The half-marathon (HM) is a very popular endurance event with important physiological and biomechanical demands. This study compared lower extremity kinematics study during phase of the start, execution, and end of HM run. Hypothesis testing on significant differences is conducted across the race stages. One male subject aged 21 years was recruited, and three cameras GoPRO HERO12 Black were utilized to capture the movements of lower extremity and Quintic Biomechanics Software v33 was employed to extract angle at hip, knee and ankle joint throughout the half- marathon run activity. The angle data was taken during start (first lap), execution (26 laps) and finish (53 laps). The result shows that there is significant difference at the knee and ankle angles during start, execution and finish. Meanwhile there was no significant difference at the hip angle. The findings of the investigation have led to insights into improving performance and reducing the risk of injury in endurance running.
