Abstract
[Purpose] The purpose of this study was to clarify the influence of the lower limb joint moment in the sagittal plane during single-leg landing on the peak value of the vertical ground reaction force. [Subjects and Methods] The subjects were 30 players belonging to a University Women’s Basketball team. Using a three-dimensional motion analysis system, each lower limb joint moment in the sagittal plane at the time of single-leg landing was calculated, and the correlation with the peak value of the vertical ground reaction force was examined. [Results] A strong negative correlation was found between the ankle moment and the peak value of the vertical ground reaction force. In addition, a positive correlation was found between the knee joint moment, and a weak positive correlation with the hip joint moment. [Conclusion] The results of this study suggest that by generating a high ankle joint moment at the time of single-leg landing, it is possible to efficiently absorb the shock, suppressing the peak value of the vertical ground reaction force.
