The purpose of this study was to evaluate the influence of gender and the cutting angle on trunk control and knee joint moments during cutting maneuvers. Male and female athletes performed unanticipated cuttings to 30° and 60°. Gender had no influence on trunk kinematics, muscles activation or knee joint moments. A sharper cutting angle increased trunk flexion (p = 0.02) and decreased trunk rotation away from the new movement direction (p < 0.001). Moreover, knee joint abduction moment was significantly increased (p < 0.001), together with altered trunk muscles co-contractions. In the early phase of the movement, the antagonist external oblique muscle appeared to work eccentrically. This might be useful to maintain the trunk lateral flexion at a certain level prior to initiate the trunk rotation towards the new movement direction.
