Biomechanical Analysis of Lower Limb Movement in Long Jumpers: Implications for Performance

Abstract

This study presents a comprehensive biomechanical analysis of lower limb movement in long jumpers, aiming to elucidate the kinematic and kinetic factors that influence performance. Using motion capture technology and force plate data, the investigation focuses on joint angles, muscle activation patterns, and ground reaction forces during the approach, take-off, and landing phases of the long jump. Key biomechanical variables such as hip, knee, and ankle joint moments and power output are examined to identify optimal movement strategies that maximize horizontal propulsion and minimize energy loss. Findings reveal that coordinated lower limb mechanics, particularly enhanced ankle plantarflexion and knee extension during take-off, are critical for achieving greater jump distances. The implications of this analysis extend to training methodologies and injury prevention strategies, providing coaches and athletes with targeted interventions to improve performance and reduce the risk of lower limb injuries. This research contributes valuable insights into the biomechanical determinants of successful long jumping, underscoring the importance of precise lower limb coordination in elite athletic performance.
