博士 / 國立體育大學 / 體育研究所 / 107 / Rowing is a combination of physical fitness and skills. In the process of improving rowing performance, skill factors outweigh physical factors. This study discussed differences between the force curves of front-, middle-, and back-loaded power modes as well as compared differences in the electromyography of different force orders. This study recruited 16 students from the rowing teams of Taipei Municipal Nei-Hu Vocational High School and National Keelung Senior High School as research targets. The students completed 20 stroke cycles on a rowing ergometer at a speed of 30 strokes/min. This study selected 10 force curves and extracted rowing performance parameters, including impulse, explosiveness, maximum force, kinematics, and dynamics. SPSS 18.0 was employed to conduct a repeat measures one-way analysis of variance as well as compare performance differences between different force orders. The results were as follows: (1) In the front-loaded phase, the rowers’ shoulders and hip joints exhibited larger bending angles to enable them to thoroughly utilize their leg drive. (2) During the movement cycle of the front-loaded phase, the force was transmitted from the legs, to the body, and then to the arms, thereby fully utilizing the rowers’ lower limb muscles. (3) Because the rowers’ body and legs simultaneously exerted force during the early force phase, the maximum and average force of this phase were significantly greater than those of the middle-loaded and back-loaded phases. Overall, the front-loaded phase was more reliant on kinetic chain principles and demonstrated the greatest efficiency in terms of muscle force, kinetic, and dynamic variables compared with that of the later phases.
