【 摘 要 】

The purpose of this study was to evaluate the validity of the AccusportTM portable bloodlactate analyzer in cold environments as compared to a reference method (Yellow SpringsInstruments enzyme electrode system [YSI]). It was hypothesized that the AccusportTMwould not be accurate in cold environments (cold 1 = 5-10 degrees C and cold 2 = < O degrees C). Subjects consisted of male and female well-trained non-athletes. A V02 max test, as well as 2 additional tests were performed on an electrically braked cycle ergometer. Blood lactate and heart rates were measured using both the YSI and AccusportTM at rest andduring the last 30 seconds of each testing stage. Blood samples of > 50 pl were drawn from the fingertip and separated for analysis. A 25 p1 sample was transferred to a buffer tube for YSI analysis in the lab at room temperature. The additional 25 p1 sample was drawn for AccusportTM an analysis under room temperature, cold 1, and cold 2 conditions. There was a consistent relationship between BL concentrations measured using theAccusportTM in all temperature environments measured in this study. However, BL concentrations achieved using the AccusportTM were about 25% greater than the reference method.
