| Summary: | 碩士 === 國立臺灣體育運動大學 === 競技運動學系碩士班 === 106 === Purpose: This study was designed to compare the effects of different warm-up protocols on the 2,000-meter rowing ergometer performance. Methods: Using crossover design and counter-balance order, eighteen young male rowers (height 172.12 ± 12.98 cm; weight 67.27 ± 22.73 kg; age 15.50 ± 2.50 years) volunteered to participate in this study. Subjects subsequently performed three different protocols: (a) rowing ergometer (2 sets x 20 progressive intensity strokes), (b) strength exercise (back squat and Snatch high pull at 30% one repetition maximum), and (c) core muscle combined with strength exercises (including prone plank, side lying plank, bridge and muscle warm-up). A 5-min passive rest period and then the subjects performed two consecutive all-out 2,000-m bouts on rowing ergometer after each warm-up condition, whereby mean power output, mean stroke rate, and split time were assessed every 500 m in addition heart rate (HR), blood lactate (BL), rating of perceived exertion (RPE) and muscle soreness were assessed at before (pre-test), immediately after warm-up, immediately and 10 minutes after 2,000-m rowing performance test. Results: RPE and muscle soreness only for the rowing ergometer warm up showed no differences from pre-test at 10-min after 2,000-m test (p > .05). No substantial differences were observed between all warm-up protocols in HR, BL, RPE and muscle soreness. There were no significant different between three warm-up protocols for 2,000-m performance test (p>.05). However, the 1500-2000-m split time significantly better than 0-500-m, and power output no significant difference in rowing ergometer warm up (p < .05), but decreased in strength exercises and core muscle combined with strength exercises protocols (p < .05). Conclusions: Three warm up protocols failed to improve 2000-m rowing performance. The rowing ergometer warm up enhance 1500-2000-m rowing performance and may accelerate recovery of RPE and muscle soreness. We encourage coaches and rowers to experiment with shorter duration and progressive intensity rowing ergometer warm-up regimens.
