• Description:
  The goal of the current study was to quantify the variability in human performance during sagittally symmetric lifting tasks. In this study, measures of human performance were limited to the three-dimensional kinematics of the lumbar region of the torso and the torque developed about the lumbosacral joint. The results of the kinematic analysis showed significant variability in the magnitude of the peak velocity and acceleration in the sagittal plane and also showed significant motion in the transverse and coronal planes, even though these were sagittally symmetric lifting tasks. The kinetic analysis showed an increase in the variability of the magnitude of the peak dynamic torque with greater levels of load, whereas coupling showed little effect on the magnitude of this variability.
