The lactate threshold (LT) and the strongly related maximal steady state workload (MLSS W ) are critical for physical endurance capacity therefore of major interest in numerous sports. However, their relevance to individual swimming performance is not well understood. We used a custom-made visual light pacer real-time speed modulation during front crawl determine LT MLSS single-exercise test. When approaching LT, we found that minute variations had considerable effects on blood concentration ([La − ]). was characterized by sudden increase [La ], while occurred after subsequent reduction, as indicated rapid cessation accumulation. Determination this so-called “individual threshold” (ILT)-test highly reproducible valid constant Mean 800 1,500 m competition (S-Comp) 3.4% above level S-Comp, difference between S-Comp (Δ S-Comp/MLSS were higher long-distance swimmers (800–1,500 m) than short- middle-distance (50–400 m). Moreover, Δ varied significantly subjects strong influence overall performance. Our results demonstrate determines performance, reflects sub- supra-threshold range, appropriate adjust training intensity moderate severe domains exercise.
