Abstract

The purpose of this study was to investigate the effect of turning movement on the three-dimensional moments at the ankle, knee, and hip joints. Data were collected using video cameras and force plate. Eight male recreational basketball players were tested during fast running (4.5m/s) and when cutting to the right or left off (+60, +30, 0, -30, and -60). The inverse dynamics approach was used to integrate the body segment parameter, kinetic and force plate data, and to solve the resultant joint moments. Greater abduction moments of the ankle, adduction moments of the knee and external rotation and adduction moments of the hip were found compared to values for straight running. Greater inversion and adduction moments of the ankle, abduction moments of the knee and hip were found compared to values for straight running.
