    This study introduces a computerized method for estimating the lactate threshold during exercise tests. The novel approach uses log-log transformations and linear regression for more objective and precise lactate threshold determination.

    Area of Science:

    • Exercise Physiology
    • Biostatistics
    • Sports Science

    Background:

    • Lactate threshold estimation traditionally relies on subjective visual data inspection.
    • Objective and reproducible methods are needed for accurate physiological assessments during exercise.

    Purpose of the Study:

    • To present a novel computerized method for determining the lactate threshold.
    • To improve the objectivity and precision of lactate threshold estimation.

    Main Methods:

    • A log-log transformation of progressive exercise test data.
    • Fitting two linear regression lines to the transformed data segments.
    • Identifying the intersection point of the regression lines as the lactate threshold estimate.

    Main Results:

    Related Experiment Videos

    • The computerized approach yields two approximately linear segments from the log-log transformed data.
    • Linear regression successfully models these segments.
    • The intersection point provides a precise estimate of the lactate threshold, with an associated confidence interval.

    Conclusions:

    • The described computerized method offers an objective alternative to visual inspection for lactate threshold determination.
    • This approach enhances the reliability and accuracy of physiological data analysis in exercise testing.
    • The method provides a statistically sound estimation of the lactate threshold.
