Acute Effects Of Exercise Under Different Levels Of Blood-Flow Restriction On 2000m Rowing Ergometer Performance / 不同血液阻斷程度對2000公尺划船測功儀 立即性運動表現影響

碩士 / 國立臺灣體育運動大學 / 競技運動學系碩士班 / 106 / Introduction: This study was to investigate the effect of three different ischemic preconditioning (IPC) protocols on repeated 2000-m rowing ergometer performance. Objective: Eighteen healthy male high school rowers were randomly performed (1) traditional warm-up (Control trial, CON), (2) progressive low pressure IPC (100 ~ 190mmHg) with traditional warm-up, (3) progressive high-pressure IPC (210 ~ 300mmHg) with traditional warm-up. Two 10 min cycles of bilateral cuff pressure inflation), muscle oxygen saturation (%) during each bout of pressure was monitored. The two consecutive 2,000-m rowing ergometer time trials were performed after each warm-up condition, whereby mean power output, mean stroke rate, total completion time, and split time were assessed. Heart rate (HR), blood lactate, rate of perceived exertion (RPE), muscle soreness, blood pressure were measured immediately and 10 minutes after the 2,000-m. Data were analyzed by a two-way mixed design of analysis of variance. Results: Both IPC groups muscle oxygen saturation (%) were higher than CON (p < .05). There were no significant differences in 2000-m rowing performance (total completion time and average power) between warm-up protocols (p > .05). The high-pressure IPC resulted in a faster completion time in the first bout (1,500-m) and the second bout (500-m) than CON and low-pressure IPC (p < .05). The high-pressure IPC resulted in greater average power in the first bout (1,500-m) than CON and low-pressure IPC (p < .05). The high-pressure IPC resulted in greater average power in second bout (500-m) than CON (p < .05), and resulted in greater in 1000-m than low-pressure IPC (p < .05). There were no significant differences in average heart rate between warm-up protocols (p > .05).The low-pressure IPC was significantly lower maximum HR than CON and high-pressure IPC ( p < .05). The RPE, muscle soreness and blood pressure were no significant differences between warm-up protocols (p > .05). The low-pressure IPC was significantly lower blood lactate than CON and high-pressure IPC in the 10 minutes after two consecutive 2,000-m rowing ergometer trials (p < .05). Conclusion: High-pressure IPC protocol improves 500-1500-m rowing performance and it elicits greater physiological strain.
