Gender Differences in Lower Extremity Kinetic Characteristics During Cutting Maneuver of Korfball

摘要


Purpose: This study investigated the gender differences in lower extremity kinetic characteristics during V-cutting maneuver of korfball. Six male and six female korfball elite players (male: age: 22.5±1.7 yrs, height: 180.7±4.2 cm, weight: 74.2±4.0 kg; female: age: 21.3±2.1 yrs, height: 169.7±4.8 cm, weight: 60.8±6.6 kg) served as the subjects of this study. Methods: A high-speed camera (100Hz) synchronized with an force plate (1,000 Hz) were used to collect the relative parameters of braking leg during the V-cutting maneuver. A Mega high-speed camera was used to record the 2D kinematics. Two-dimensional coordinates were derived by a motion analysis system to gain the kinematics parameters of human lower extremity. The inverse dynamics approach was used to integrate the body segment parameter, kinematics and kinetics data, and to solve the resultant lower joints forces and moments. Results: There were significant differences on the neutral axis stress (Male -1.84±0.15 B.W.; Female -2.43±0.32 B.W.) and sheer force (Male -2.10±0.12 B.W.; Female -2.50±0.22 B.W.). Conclusion: As a result, which might lead to injuries, especially knee joint ones, while female players performed the V-cutting maneuvers. It was suggested that female players should strengthen the training of the lower segment and work on the skills.
