The aim of this study was to examine whether swimming with-out pace-lights affects lactate test results compared to swimming with pace-lights. Each of the 11 competitive swimmers per-formed, in a randomized order, on one day with paced workloads and one day without. The test protocol consisted of five 400m front crawl workloads with increasing velocity. Predetermined velocities for each swimmer were either paced using a set of 14 pace-lights moving below the swimmer or self paced. Mean velocities of paced or unpaced workloads at lactate values of 2, 3, 4 and 5 mM showed no statistical differences (p>0.05), and mean Standard deviation of lap times was 0.60±018 and 0.57±0.17s for the paced and unpaced trials respectively (p>0.05). This study shows that during lactate testing, competitive swimmers are able to hold an even pace and meet predetermined workloads without the use of external pacing.
