This study presents a biomechanical assessment of semi-professional rugby players using markerless motion capture techniques and pressure sensors applied directly on the field. The objective was to analyze kinematic and kinetic variables during an unanticipated change of direction, identifying possible risk indicators for anterior cruciate ligament (ACL) injury. Twelve athletes were monitored using four synchronized GoPro cameras and XSensor pressure insoles. The collected data, processed with Track On Field, Pose2Sim, and MATLAB, enabled the calculation of joint angles, ground reaction forces, and flexion/extension and abduction/adduction moments of the hip, knee, and ankle joints. The analysis revealed the possibility of distinguishing athletes with biomechanical profiles differing from the team average. The results confirm the validity of the on-field markerless approach for motion evaluation in rugby and its potential application in injury prevention programs.
Lo studio presenta una valutazione biomeccanica di atleti semi-professionisti di rugby mediante tecniche markerless motion capture e sensori di pressione, applicate direttamente sul campo. L’obiettivo è stato analizzare le variabili cinematiche e cinetiche durante un cambio di direzione non anticipato, individuando possibili indicatori di rischio per l’infortunio al legamento crociato anteriore. Dodici atleti sono stati monitorati con quattro videocamere GoPro sincronizzate e solette di pressione XSensor. I dati, elaborati con Track On Field, Pose2Sim e MATLAB, hanno permesso di calcolare angoli articolari, momenti di flessione/estensione e abduzione/adduzione delle articolazioni di anca, ginocchio e caviglia, oltre alle forze di reazione al suolo. L’analisi ha evidenziato la possibilità di distinguere soggetti con profili biomeccanici differenti rispetto alla media della squadra. I risultati confermano la validità dell’approccio on-field markerless per la valutazione del movimento nel rugby e la sua potenziale applicazione in programmi di prevenzione degli infortuni.

Abstract
This study presents a biomechanical assessment of semi-professional rugby players using markerless motion capture techniques and pressure sensors applied directly on the field. The objective was to analyze kinematic and kinetic variables during an unanticipated change of direction, identifying possible risk indicators for anterior cruciate ligament (ACL) injury. Twelve athletes were monitored using four synchronized GoPro cameras and XSensor pressure insoles. The collected data, processed with Track On Field, Pose2Sim, and MATLAB, enabled the calculation of joint angles, ground reaction forces, and flexion/extension and abduction/adduction moments of the hip, knee, and ankle joints. The analysis revealed the possibility of distinguishing athletes with biomechanical profiles differing from the team average. The results confirm the validity of the on-field markerless approach for motion evaluation in rugby and its potential application in injury prevention programs.| File | Dimensione | Formato | |
