Although VO2max is the index which represents maximum aerobic power, the corresponding exercise velocity (vVO2max) can be different in athletes with the same VO2max values. This study investigated associations between absolute (VO2pabs), relative (VO2pre) VO2peak, and vVO2max for aerobic performances determined in the field. Thirteen runners, aged 20.1±2.1 years, height 170±0.1 cm, and weight 66.0±3.7 kg participated from the 13th Armoured Infantry Battalion (Brazilian Army) based in Ponta Grossa, PR, Brazil. Participants were submitted to an exhaustive progressive test in a treadmill with 12km.h-1 initial velocity, 3min stages, and 1 km.h-1 increments. Breath-by-breath gas samples were collected (Parvomedics – TrueOne, 2400 – USA) to determine VO2pabs, VO2pre, and vVO2peak. They later performed three maximum effort tests on an athletics track over 1200m (P1200), 2400m (P2400), and 2800m (P2800). Associations between laboratory and maximum performances were verified by the Pearson correlation test at 95% significance level. VO2pabs presented significant correlations with the 2400m (r=0.64; p=0.02) and 2800m (r=0.58; p=0.04) tests, but not the P2800. VO2pre significantly correlated only with the 2400m (r=0.61; p=0.02) test. However, vVO2peak presented high correlations with all three; P1200 (r=0.87; p=0.0001), P2400 (r=0.86; p=0.0001), and P2800 (r=0.80; p=0.001). We can therefore conclude that vVO2peak was the best predictor for P1200m, P2400m, and P2800m.
