Abstract

This study aimed to compare the performance of a new portable lactate analyser against other standard laboratory methods in three conditions, normal (20 ± 1.3 °C; 40 ± 5 % RH), hot (40 ± 2.5 °C; 40 ± 5 % RH), and humid (20 ± 1.1 °C; 82 ± 6 % RH) conditions. Seven healthy males, ([Mean ± SE]: age, 26.3 ± 1.3 yr; height, 177.7 ± 1.6 cm; weight, 77.4 ± 0.9 kg, V˙O2max, 56.1 ± 1.9 ml × kg × min-1) undertook a maximal cycle ergometry test to exhaustion in the three conditions. Blood was taken every 3 min at the end of each stage and was analysed using the Lactate Pro LT-1710®, the Accusport®, the Analox© GM7 and the Kodak© Ektachem™ systems. The MANOVA (Analyser Type × Condition × Workload) indicated no interaction effect (F(42, 660), = 0.45, p > 0.99, Power = 0.53). The data across all workloads indicated that the machines measured significantly differently to each other (F(4,743) = 14.652, p < 0.0001, Power = 1.00). The data were moderately to highly correlated. We conclude that the Lactate Pro is a simple and effective measurement device for taking blood lactate in a field or laboratory setting. However, we would caution against using this machine to compare data from other machines.
