英文摘要 | Introduction: Rowing is a sport in which the propulsion forces come from human hands rapidly operating the oars; therefore, the oar is the most important equipment in this sport. Approximately 220 to 250 cyclic rowing strokes would occur in a 2000 meter rowing race. In Taiwan, the length of oar chosen for rowing races and training are all along either by approximation or with reference to foreign athletes’ choices. Purpose: This study was to examine the kinetics and kinematics of 3 different oar lengths in stroke action. Methods: 12 male collegiate rowers were recruited as subjects (height: 175.27 ± 4.8cm; weight: 76.55 ± 4.6kg; years of rowing training: 6.36 ± 1.8 years). The data was measured and recorded by the RowX-modelB outdoor display at 200 Hz and in 60-sec sampling time. This study was carried out with three different oar lengths, SOT (374 cm), MOT (376 cm) and LOT (378 cm), at a fixed rowing-stroke rate (34±1 s/min) and the data of kinetics and kinematics gathered were subjected to statistical analysis by using SPSS 12.00. Results: In terms of kinetics, SOT performed better than MOT and LOT and showed significant differences (p |
