Comparação dos analisadores de lactato accusport e yellow springs Comparison of accusport and yellow springs lactate analyzers

FRANCHINI, E., MATSUSHIGUE, K.A., COLANTONIO, E., KISS, M.A.P.D. Comparison of accusport and yellow springs lactate analyzers. R. bras. Ci e Mov. 2004; 12(1): 39-44. Blood lactate analysis has been used to training control and prescription in different sports. Nevertheless, there are many lactate analyzers, among which the most used in Brazil are the Accusport and the Yellow Springs 1500 Sport. The objective of this sutdy was to compare the results measured in both analyzers from the same blood sample. Sixty eigth samples were measured. Values measured in one equipment were not equivalent to the values measured in the other one. For concentrations lower than 5 mM, the Accusport apparatus overestimates the results compared to the Yellow Springs and the opposite happens when blood lactate concentration is higher than 5 mM, indicating a need of different equations for each concentration range. Furthermore, the proposed equations can be used to correct the values measured in the Accusport apparatus and to obtain the values that would be measured with the utilization of theYellow Springs.
