The purpose of this study was to determine the best prediction factors of traditional rowing performance in traditional elite (ER) and amateur (AR) rowers. Average power during the 20-min all-out test (W(20 min)), average power output which elicited a blood lactate concentration of 4 mmol l(-1) (W(4 mmol l(-1))), power output in 10 maximal strokes (W(10 strokes)), maximal strength and muscle power output during a bench pull (BP) and anthropometric values were all measured for 46 trained male rowers aged 21-30 with 8-15 years of rowing training experience. The ER group showed greater body mass (5%, p < 0.05), greater fat free body mass (5%, p < 0.05), greater 1RM(BP) (13%, p < 0.001), longer training experience (43%, p < 0.001), and a shorter time in the 2,000 m test (4%, p < 0.05) than the AR group. The ER group showed higher power output values in W(10 strokes) (9%, p < 0.01), W(20 min) (15.4%, p < 0.01) and (W(4 mmol l(-1))) (17.8%, p < 0.01) compared with the AR group. Significant relationships were observed between (W(4 mmol l(-1))) and W(20 min) (r = 0.65 and 0.80; p < 0.01 in ER and AR, respectively). The indices for rowing performance suggested that W(20 min), (W(4 mmol l(-1))), W(10 strokes) and 1RM(BP) were the most important predictors of traditional rowing performance in elite and amateur rowers.
本研究旨在确定传统划船运动中传统精英（ER）和业余（AR）划手的最佳预测因素。20 分钟全力测试的平均功率（W(20 min)）、产生 4 毫摩尔/升血乳酸浓度时的平均功率输出（W(4 mmol l(-1)))、10 次最大划桨的功率输出（W(10 次划桨)）、卧推（BP）的最大力量和肌肉功率输出以及人体测量值均测量了 46 名年龄在 21-30 岁、有 8-15 年划船训练经验的男性划船运动员。与 AR 组相比，ER 组表现出更大的体重（5%，p<0.05）、更大的去脂体重（5%，p<0.05）、更大的 1RM（BP）（13%，p<0.001）、更长的训练经验（43%，p<0.001）和 2000 米测试的时间更短（4%，p<0.05）。ER 组在 W(10 次划桨)（9%，p<0.01）、W(20 min)（15.4%，p<0.01）和（W(4 mmol l(-1)))（17.8%，p<0.01）的功率输出值均高于 AR 组。在 ER 和 AR 中，（W(4 mmol l(-1)))与 W(20 min)之间存在显著相关性（r=0.65 和 0.80；p<0.01）。划船表现的指标表明，W(20 min)、（W(4 mmol l(-1)))、W(10 次划桨)和 1RM（BP）是精英和业余划手中传统划船表现的最重要预测因素。
