The aim of the study presented was to assess the relationships between the 6-minute "all-out" rowing ergometer test with physical performance indices in college rowers. Ten male rowers (21.60+4.20 yrs; 186,90+5.64 cm; 84.10+6.59 kg; %body fat: 9.62+2.81%) performed a 6-minute "all-out" rowing ergometer test on a rowing ergometer (Concept II, USA) at the first measurement session. In addition, a graded exercise test at the intensities of 150, 200 and 250 W (6-minutes each) and a maximal 5x1 minute interval test were performed at separate measurement sessions. The heart rate (HR) was recorded at the end of each load during a graded exercise test. The individual physical working capacity (PWC) of the rowers was calculated at the maximum of HR recorded during a 6-minute "all-out" test. Blood samples for lactate (LA) determination were obtained from the fingertip before and immediately after each bout of exercise. The anaerobic threshold (AT) indices were determined by interpolation from the relationships between the LA concentration and the respective variable at a LA concentration of 4.0 mmol/l. The LA concentration in the blood was also determined before, immediately after and after 3 minutes and 5 minutes of recovery of the maximal 5 x 1 minute interval test. Significant correlations (p<0.05) were observed between the AT (W) and power (r=0.56) and the covered distance (r=0.55) of a 6-minute "all-out" test. In addition, the power and distance covered of the 6-minute "all-out" test were significantly related to the covered distance and power of all five trials of the maximum interval test (r=0.64-0.77). The stepwise multiple interval test indicated that the power of a 6-minute "all-out" test was explained by the mean power of a maximal 5 x 1 minute interval test at 82.75% (R2). In conclusion, the results of our study suggest that our proposed interval test has a high diagnostic value in the assessment of the anaerobic work capacity of rowers.
