Abstract

Introduction: During speed skating klapskates are used with a hinge placed just in front of the ball of the foot. The position of the-hinge is suggested to be of importance for the effectiveness of the klapskate. This study investigated the effect of the position of hinge position on acceleration components during a stroke. Methods: Three Dutch elite speed skaters skated seven trials of 500 m in a fixed velocity. In each trial the hinge was displaced in anterior or posterior direction and three laps were used to to get accustomed to the new position. A pre and post measurement was done with the skaters preferred hinge position. Acceleration components were measured with a tri-axial accelerometer which was attached to the back of the skater with a neoprene belt. Accelerometer data of the last straight 100 m of each trial was used. The data was transformed into a horizontal-vertical orthogonal coordinate system. Results: A successful method was to measure 3D acceleration components during speed skating was developed. Although the results did not show any structural differences in accelerations at given hinge positions, more insight has been gained regarding the biomechanical aspects of speed skating. Conclusion: Although 3D acceleration components could be measured, no marked effect of the hinge position was on them was observed. Since the peaks in the acceleration components can be identified during strokes and because of consistency of acceleration patterns between trails of one skater and successive left or right strokes the used method is promising for future research when combined with other measurement tools, also given the condition of free motion.
