博士 / 國立臺灣師範大學 / 體育學系 / 92 / Each rower required performing 220 to 250 strokes during a 2000 meters competition rowing. Due to these high-repeated strokes, the efficient of the leg drive will influence the rowing performance. Therefore, the purpose of this study was to investigate the effect of foot-stretcher angle (39°, 42°, 45° and 48°) on the drive phase in rowing.
Twelve elite female rowers participated in this study (21.3 ± 1.7 years, 164.5 ± 4.1 cm and 58.0 ± 4.9 kg), and each subject was asked to perform 1-min test under four foot-stretcher angles on Concept II rowing ergometer. One JVC digital camera (60 Hz) was used to recorded sagittal plane kinematics during rowing, and Biovision load cell (600 Hz) were synchronized with Kistler force plate (600 Hz) to collect the pulling force and foot-stretcher reaction force. The selected variables were tested by one-way repeated ANOVA. Statistical significance was set at α = .05.
The result indicated that when increase the foot-stretcher angle, the maximum and minimum angle of the ankle and ankle’s range of motion were decrease. It was concluded that the rower could produce a higher mean power per stroke and mean power per drive stroke in 39° foot-stretcher. In addition, when adjusting the foot-stretcher angle, the motion of ankle joint was changed. It was suggested that the rower could choose 39° foot-stretcher in training and competition.
