We compared three different incremental swim protocols to identify differences in submaximal velocities at 3 and 4 mmol•L-1 arterial lactate concentration. Ten male elite swimmers performed three different step test protocols in randomized order. Two protocols were with constant distances (200 m) but varying duration throughout the test. The third test procedure was a protocol with constant times (3 min each) for every increment. Arterial lactate concentration was obtained at the end of every increment. The protocol with constant time per increment resulted in significantly slower velocities (-0.04 m•s-1) at fixed lactate values (p < 0.01). We showed that the commonly used protocols with constant distances revealed higher submaximal velocities for given lactate concentrations (3 and 4 mmol•L-1) compared to constant increments.
