This study aimed to make a comparison between three methods used to estimate the amount of lactate accumulation in response to supramaximal exercises.

One of these methods was the method proposed by Margaria et al. nearly 50 years ago, which consisted in estimating the quantity of lactate accumulated during supramaximal exercise, taking into account the peak blood lactate concentration during recovery and the volume of lactate distribution.

This method was compared to two other methods to estimate the amount of lactate accumulated in response to supramaximal exercises. Maciejewski et al. investigated the correlation between the accumulated oxygen deficit and the three methods of estimating the quantity of lactate accumulated.

Nine highly trained lightweight participated in this study. Trials involved two exercise sessions carried out at least 3 days apart in a rowing ergometer that provided continuous feedback on power output and stroke rate.

As a conclusion, although the original method of Margaria et al. does correlate positively with the accumulated oxygen deficit, the correlation coefficients using the two new methods described in this study were much higher.
