碩士 / 臺北市立大學 / 運動器材科技研究所 / 105 / The purpose of this study was to compare the difference of rowing kinematics and kinetic between with dynamic (DE) or slide ergometers (SE). Eight male college rowers with more than three years of rowing experience were recruited as participants. They rowed 500 meter on DE or SE at average power output equivalent to a 2000 meter race. During rowing process, a load cell was used to collect the peak force, impulse, drive time, recovery time, stroke ratio and time to peak force; infrared high-speed cameras were record the rowing performance of lower extremity. All parameters was analyzed to compare values between the two conditions, using a paired t-test by SPSS v 12.0. Results: The drive impulse and stroke ratio of DE were significantly greater than SE. The peak angular velocities of hip, knee, and ankle joints as well as time to peak during driving phase were no difference between two condition; however, the time to peak angular velocities of hip, knee, and ankle joints of DE were significantly slower than SE during recovery phase. Conclusion: More driving force efficacy by DE is better for training rowing power, but rapid recovery movement on SE is suitable for improving rowing action fluency.
