The aim of this study was to point out a biomechanical analysis of the poling cycle (PPG) achieved from CC sit-skiers to evaluate kinematics. In addition, starting from the analysis of the poling cycle performed from LW1O athletes, with no functional abdominals or extensors and no buttock sensibility, it has been observed how inertial effect due to the abrupt lowering of the arms may assure a propulsive force at the beginning of the PPG cycle. An in-field markerless motion capture technique was used during the 2010 winter Paralympic Games in Vancouver (Canada), with the approval and support of the International Paralympic Committee (IPC). Despite the complexity concerning the in-field measurements due to the weather and snow conditions, authors considered important to start from a kinematic analysis of elite disabled athletes during a competition context at the best of their performances.
