Abstrakt: 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 RT ) 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 RT test, and a retest. The validity of the 6-min RT was determined by comparing maximum oxygen uptake (VO 2max ) and power output (PO) between the IT and 6-min RT . Reliability included the coefficient of variation (CV), intra-class correlation coefficient (ICC), and mean standard error between the 6-min RT test and retest. The significance level was p < 0.05.
Results: There was no significant difference in VO 2max in both IT and 6-min RT ( p = 0.18), while the mean power output (P mean ) generated in the 6-min RT equaled 91.96% of the maximal aerobic power (MAP) generated in the IT ( p = 0.004). Reliability analysis for the 6-min RT showed a CV = 0.50% and ICC = 0.97 for distance, a CV = 1.85% and ICC = 0.96 for P mean .
Conclusion: From a ventilatory and mechanical point of view, the 6-min RT is a maximally valid test for establishing MAP in amateur rowers. Also, the 6-min RT evidences a high degree of agreement between days. Therefore, the 6-min RT is a valid and reliable test for assessing PO in amateur male rowers.
