The νcrit, defined as the swimming velocity over a very long period of time without exhaustion, was expressed as the slope of a straight line between swimming distance (d lim) at each speed (with six predetermined speeds) and the duration (t lim). Nine trained college swimmers underwent tests in a swimming flume to measure νcrit at those velocities until the onset of fatigue. A regression analysis ofd lim on trim calculated for each swimmer showed linear relationships (r 2>0.998,P<0.01), and the slope coefficient signifying νcrit ranged from 1.062 to 1.262 m · s−1 with a mean of 1.166 (SD 0.052) m · s−1. Maximal oxygen consumption ( $$\dot VO_{2\max } $$ ), oxygen consumption ( $$\dot VO_2 $$ ) at anaerobic threshold, and the swimming also velocity at the onset of blood lactate accumulation (νOBLA) were also determined during the incremental swimming test. The νcrit showed significant positive correlations with $$\dot VO_2 $$ at anaerobic threshold (r=0.818,P<0.01), νOBLA (r=0.949,P<0.01) and mean velocity of 400m freestyle (r=0.864,P<0.01). These data suggested that νcrit could be adopted as an index of endurance performance in competitive swimmers.
