碩士 / 國立體育學院 / 運動教練研究所 / 85 / Nowadays, rowing gets more attention in Taiwan area, and more athletes are involved in this new-developed sport. An understanding of the dynamic characteristics of rowing movement is important to enhance the rower''s competition ability. Therefore, this study was designed to analyze the dynamics of rowing movement by comparing the maximum rowing strength, maximum strength appearing time, force-time imtegral, locus of center of mass, as well as change of hip, knee and ankle joints. Based on the results obtained, several conclusions can made:
1. Kinetic Analysis: The maximum rowing strength, slope of force-time curve and impulse of elite athletes are significantly larger than those of general athletes, and it is significantly different among various phase. The maximum rowing strength of elite athletes occurs significantly earlier than general athletes, and it is significantly different among various phases. Furthermore, the duration of driving period is significantly different among various phases.
2. Kinematic Analysis: The horizontal movement of center of mass of elite athletes is significantly larger than that of general athletes. Both peak values of horizontal velocities of center of mass during driving and recovering phases are significantly larger than general athletes. The stroke distance of elite athletes is signifiaantly larger than general athletes. Furthermore, the knee and ankle angular velocities of elite athletes are significantly larger than general athletes. And the hip angular velocity of elite athletes is significantly smaller than general athletes.
Using this experimental device can provide an effective and direct way to evaluate rowing movement. Consequently, coach can arrange rowers who have similar driving form on the same boat to increase the stability of boat and boat speed.
