LACTATE ANALYZERS ARE RELIABLE BUT DIFFER IN LACTATE THRESHOLD LEVELS
Miles, D. S., Cox, M. H., Verde, T. J., Evangelisti, M. I., Moser, C. D., & Kuesel, L. (1998). Comparison of the Accusport, YSI 1500, and YSI 23L lactate analyzers during progressive cycle ergometer exercise. Medicine and Science in Sports and Exercise, 30(5), Supplement abstract 195.
The YSI instruments and the Accusport analyzer produced similar test-retest results indicating that the instruments are reliable. However, the Accusport values were consistently and significantly higher than YSI values at the same workloads.
Implication. Accusport analyzers define lactate thresholds at lower exercise intensities than do YSI instruments.
