BACKGROUND
Standardized tests are currently available to assess power output in elite rowers. However, there are no valid and reliable tests to assess power output in amateur rowers.
OBJECTIVE
This study aimed to determine the validity and reliability of a 6-min rowing ergometer test (6-min) as a predictor of power output (PO) in amateur male rowers.
METHODS
Twelve male amateur rowers were part of the study. All participants were instructed to perform an incremental test (IT), a 6-min test, and a retest. The validity of the 6-min was determined by comparing maximum oxygen uptake (VO) and power output (PO) between the IT and 6-min. Reliability included the coefficient of variation (CV), intra-class correlation coefficient (ICC), and mean standard error between the 6-min test and retest. The significance level was < 0.05.
RESULTS
There was no significant difference in VO in both IT and 6-min ( = 0.18), while the mean power output (P) generated in the 6-min equaled 91.96% of the maximal aerobic power (MAP) generated in the IT ( = 0.004). Reliability analysis for the 6-min showed a CV = 0.50% and ICC = 0.97 for distance, a CV = 1.85% and ICC = 0.96 for P.
CONCLUSION
From a ventilatory and mechanical point of view, the 6-min is a maximally valid test for establishing MAP in amateur rowers. Also, the 6-min evidences a high degree of agreement between days. Therefore, the 6-min is a valid and reliable test for assessing PO in amateur male rowers.
背景
目前已有标准化测试可用于评估精英赛艇运动员的输出功率。然而，尚无有效的、可靠的测试方法来评估业余赛艇运动员的输出功率。
目的
本研究旨在确定 6 分钟划船测功仪测试（6 分钟）作为预测业余男性赛艇运动员输出功率（PO）的有效性和可靠性。
方法
12 名男性业余赛艇运动员参加了本研究。所有参与者均被要求进行递增测试（IT）、6 分钟测试和复测。通过比较 IT 和 6 分钟测试之间的最大摄氧量（VO）和输出功率（PO），确定 6 分钟测试的有效性。可靠性包括变异系数（CV）、组内相关系数（ICC）和 6 分钟测试和复测之间的平均标准误差。显著性水平为 < 0.05。
结果
IT 和 6 分钟测试的 VO 无显著差异（ = 0.18），而 6 分钟测试产生的平均功率输出（P）等于 IT 中产生的最大有氧功率（MAP）的 91.96%（ = 0.004）。6 分钟测试的可靠性分析显示，距离的 CV = 0.50%，ICC = 0.97，P 的 CV = 1.85%，ICC = 0.96。
结论
从呼吸和力学角度来看，6 分钟是确定业余赛艇运动员 MAP 的最有效测试。此外，6 分钟在两天之间表现出高度的一致性。因此，6 分钟是评估业余男性赛艇运动员 PO 的有效可靠测试。
