Standard advice for beginner and intermediate snowboarders is to place your weight on the front foot when following the fall line or traversing the slope. This stance is considered best for beginner or intermediate snowboarders who are learning how to shift their center of gravity to the front of the board to turn the nose toward the fall line[ called‘nosedrop’in Japanese] or to rotate the board when traversing the slope. The purpose of this study is to determine whether this is also the best stance for advanced snowboarders. Our research suggests that when snowboarders make a carving turn, excessive pressure on the forefoot may make it difficult to perform an ideal turn as the tip of the board may cut into the snow surface more than necessary and create more resistance than necessary. In this study, we measured the pressure distribution and center of pressure( COP) applied to the soles of both feet when the vertical movement was performed while standing straight or leaning forward with respect to the slope. The results showed that the pressure distribution of the forefoot decreased when all subjects moved vertically. In addition, when all subjects moved vertically, the COP moved nearer the center of the stance. The results suggest that it is possible to perform carving turns with less deceleration by standing up vertically, and as a result preventing the tip of the board from digging into the snow surface more than necessary and consequently receiving more resistance from the snow surface than necessary.
