PURPOSE: This study aims to carry out a comparative analysis of measuring methods to predict a critical power in rowers. METHODS: Three types of tests were performed for seven male university rowers: 1) a critical power determination test, 2) a 3‑ and 6‑minute all‑out rowing test, 3) a 2,000 m simulated rowing test. The CP and W΄ were determined from the regression between work and time to exhaustion, derived from two exhaustive trials at 60, 70% of the maximal power, and 3‑, 6‑minute all‑out rowing test to estimate the EP and WEP. The test data were analyzed by paired t‑test, one‑way ANOVA, and Pearson correlation. RESULTS: Comparing the differences between the 3‑ and 6‑minute all‑out tests, EP (p<.001) showed that the 6‑minute test was lower than the 3‑minute test and WEP (p<.001) was higher. There was a significant (p<.01) difference between the EP of the 3, 6‑minute test and CP of 60%, 70% Pmax, WEP of the 3, 6‑minute test and W΄ of 60%, 70% Pmax. The 2,000 m mean power of 2,000 m was positively correlated with 3‑minute EP, 6‑minute EP, 60% CP and 70% CP. The 6‑minute EP had a positive correlation with the 3‑minute EP, 60% CP and 70% CP, but 3‑minute EP did not have a correlation with 60% CP and 70% CP. CONCLUSIONS: A non‑invasive 6‑minute all‑out critical power test using a rowing ergometer can be a practical protocol for monitoring the effectiveness of the training program during the off‑season or evaluating the 2,000 m record. Additionally, 6-minute EP and WEP have moderate reliability, and are able to appropriately estimate the aerobic capacity and anaerobic capacity in rowers.
