 note = {The refinement and improvement of ice sledge propelling techniques, particularly those of high caliber athletes competing in Paralympic Games, demands detailed knowledge of the mechanical characteristics of the ice sledge propelling movement pattern. The purpose of this study was to investigate the sprint start motion of ice sledge speed racing in 1998 Nagano Winter Paralympic Games. Four male competitors were video recorded by two high-speed video cameras at 200 fps during the 100m races. The direct linear transformation method was used to obtain three-dimensional movements of upper limbs, trunk and ice sledge. Linear velocities of the sledge and body segments and three joint angles were calculated. Contrasting patterns of velocity-time curves in the ice sledge and the competitor's shoulder were observed in the ice sledge propelling. Similarity was observed in rowing. Also all competitors exhibited a similar series of angular motions; trunk extension - elbow extension - shoulder flexion - trunkflexion - elbow flexion - shoulder extension during each cycle. However, these kinematic variables did not show any relation to performance time. The fact that this might be connected to the absence of mechanical energy and efficiency during start was indicated.},
