This study was designed to observe physiological response during one bout of high-intensity intermittent short time rowing exercise and to evaluate the effect of repeated bouts of the exercise on rowing performance for college oarsmen.The high-intensity, intermittent exercise consisted of either five or eight bouts of 20-sec rowing with the maximal effort of the subjects, and each bout was separated by 10-sec rest. In the first experiment, subjects reached to the maximal level of VO_2 and heart rate at the fourth set during both 5- and 8- sets of high-intensity, intermittent exercises. However, blood lactate concentration after high-intensity, intermittent exercise was significantly lower in the 5-set protocol than in the 8-set protocol (9.0±1.2vs. 11.3±1.6mM, p<0.05), suggesting that the 8-set protocol is much vigorous and better than the 5-set protocol as high-intensity, intermittent rowing exercise for rowers. In the 6-week rowing training, low frequency group (LF: 2 times/week) markedly improved their rowing performance (Δ3.2±1.9sec/1000m, Δ8.4±5.5sec/2000m time trials), whereas high frequency group (HF: 5 times/week) improved only in 1000m trial (Δ4.5±2.3sec).Bowers performed 5-week training regimens by single scull boat on water which consisted of high-intensity rowing exercise(8 sets/bout, 2 times/week). Their rowing performance in the 2000m-time trial on ergometer was significantly improved.These results suggest that high-intensity, intermittent rowing exercise on both ergometer and on water, which consists of 20-sec maximal exertion with 10-sec interval, 8 sets/bout, 2 times/week, more than 6 weeks, could be recommended to the collegiate rowers in order to improve their rowing performance.

本研究旨在观察大学生桨手进行一轮高强度间歇性短时间划船运动时的生理反应，并评估重复运动对划船运动表现的影响。高强度间歇性运动包括受试者尽最大努力进行五次或八次20秒划船运动，每轮运动间隔10秒休息。在第一个实验中，受试者在 5 组和 8 组高强度间歇训练中，在第四组时达到了最大摄氧量和心率水平。然而，高强度间歇运动后的血乳酸浓度在5组方案中显着低于8组方案（9.0±1.2vs.11.3±1.6mM，p<0.05），这表明8组方案比5组方案更有活力，作为赛艇运动员的高强度间歇性划船运动要好。在为期6周的划船训练中，低频组（LF：2次/周）显着提高了划船成绩（Δ3.2±1.9秒/1000m，Δ8.4±5.5秒/2000m计时试验），而高频组（HF：5次/周）仅在1000m试验中有所改善（Δ4.5±2.3秒）。Bowers通过单次训练进行了5周的训练方案橹船上 水，其中包括高强度划船运动（8组/回合，2次/周）。其在2000米测速试验中的赛艇成绩得到显着提高。这些结果表明，可以建议大学生赛艇运动员进行高强度、间歇性的测速和水上划船运动，即20秒最大强度，间隔10秒，8组/场，2次/周，持续6周以上，以提高其赛艇成绩。
