碩士 / 國立體育大學 / 教練研究所 / 98 / The purpose of this study was to investigate the paddle movement with different paddle frequency in Taiwan elite Canadian canoe players. Eight Canadian canoe single and double canoe players had won the top six in 2007 Taiwan National Athletic Games join this experiment. Everyone execute four different paddle frequency(N-spm、50spm、60spm、70spm), every frequency execute three times and 20 seconds per stroke. The Motion Analysis System with 8 high-speed cameras at 100 Hz (Motion Analysis Corporation, Santa Rosa, USA) measure the average displacement, angular displacement, velocity, angular velocity, acceleration, angular acceleration in shoulder, elbow, wrist, hip, knee, ankle joint, trunk and the different of the stroke displacement in different paddle frequency in each phases. The repeated one-way ANOVA is used to calculate the data through SPSS 12.0. The result was showed the moment of paddle touch the water, the angle of the upper and lower limb has no significant difference, the velocity and angular velocity have the tendency was increased when increase the paddle frequency. In the moment of the paddle vertical to the ground, the angle of the upper and lower limb has no significant difference; the velocity was significant difference in the wrist of the paddle push and pull, the elbow of the paddle pull, and the shoulder of the paddle push. The angular velocity have the tendency was increased when the paddle frequency increased, besides the elbow and the shoulder of the paddle push. The moment of the paddle out of the water, only the elbow of the paddle pull was significant difference. The velocity was significant difference in the wrist of the paddle push, the elbow of the paddle push, the balance knee and ankle. The angular velocity in the elbow of the paddle pull, the balance knee and the kneel knee have the tendency was increased when the paddle frequency increased. The phase of the paddle pull the water, only the displacement has significant difference in the balance ankle, and the paddle have the tendency was decreased when the paddle frequency increased. The angular displacement has no significant difference, but the balance ankle have the tendency was increased when the paddle frequency increased. The acceleration, angular velocity and angular acceleration have the tendency was increased when the paddle frequency increased. The angle of the forward bend trunk and the angle of the flexion hip have the tendency was decreased when the paddle frequency increased. The phase of the paddle push the water, the displacement of the wrist of paddle push and pull, the shoulder of the paddle push and pull, and the elbow of the paddle pull have the tendency was decreased when the paddle frequency increased, but the balance ankle was opposite. The angular displacement of the kneel knee and the balance ankle have the tendency was decreased when the paddle frequency increased. The velocity and the acceleration of the upper and lower limb have the tendency was increased when the paddle frequency increased, besides the acceleration of the ankle. The angular velocity has faster stretching movement when the paddle frequency increased. The angular velocity in the shoulder pull stretching and the flexion angle of the hip of the paddle pull was less with the paddle frequency increased. The phase of the paddle return, the displacement of the elbow of the paddle pulls, the shoulder of the paddle push and pull have the tendency was decreased when the paddle frequency increased, but the balance ankle and the kneel knee was opposite. The angular displacement of the balance knee and ankle, the kneel knee have the tendency was decreased when the paddle frequency increased. The velocity of the upper and lower limb have the tendency was increased when the paddle frequency increased, besides the kneel knee, the acceleration have the same condition with the velocity. The angular velocity only has significant difference in the elbow of the paddle push and the shoulder of the paddle pull, the tendency was increased when the paddle frequency increased. The angular velocity in the elbow of the paddle push and pull, and the shoulder of the paddle pull have the tendency was increased when the paddle frequency increased. The tempo of the paddle, the phase of the push and pull water is the key element let the canoe can move forward. The elite Canada style canoe players in our country cannot have good performance in the beginning at the phase of the paddle pull. It could be affect the efficiency of the paddle. The phase of the paddle push, it was no significant difference between this study and previous research in our country Canada style canoe players. This study hope can depend on the motion analysis to realize the paddle stroke characteristic with four different paddle frequencies in each phase to show some scientific and quantification data provide to coaches and players to consult this research.
