The present study examines the feasibility of and differences in measurement of oxygen uptake via lactate threshold using two different methods: the logarithm transformation model and the continuous transformation model. Subjects were eight males form Taipei Teachers’ College Department of Physical Education (age=22.10+/-0.82 years, height=177.10+/-2.92cm; weight=71.66+/-5.74 kg) who submitted to lactate threshold measurements after MacDougall et al. During exercise, blood samples were drawn form the antecubital vein for use as samples in analyzing lactate concentration. The data thus obtained were analyzed using mathematical modeling to determine the oxygen uptake corresponding to an ideal lactate threshold value, and analyzed with t-tests and ANOVA. Results are as follow: 1. The difference between oxygen uptake values obtained through lactate thresholds for logarithm transformation and continuous transformation was not statistically significant (P>.05). 2. The confidence interval for determination of oxygen uptake using lactate threshold through continuous transformation was R=.91. 3. The confidence interval for determination of oxygen uptake using lactate threshold through continuous transformation was R=.95 Based on the preceding results, the following conclusions are obtained: 1. There is no statistically significant difference between oxygen uptake values obtained through lactate thresholds for logarithm transformation and continuous transformation. 2. Logarithm transformation and continuous transformation methods are both reliable and are suitable for promotion and use within Taiwan.
