Welcome to the LT-web services!

This site contains tools for analyzing lactate curves and to estimate various aerobic and anaerobic lactate thresholds and markers.

Information

We offer services for the analysis of blood lactate measurements performed during incremental (e.g. treadmill) tests. Functionalities include lactate model fitting and evaluation, aerobic lactate threshold and anaerobic lactate threshold (also referred as maximal lactate steady state - MLSS, or lactate turnpoint) estimations. Currently the following models are available for lactate model fitting:

  • Exponential
  • 3rd and 4th degree polynomial
  • Cubic and smooth spline - Piecewise polynomial
A robust version of the 3rd degree polynomial is also available, which is less sensitive to outliers.

We also show some examples in various programming languages to help you with the integration of our services in 3rd party software. Demos using our services are available to download for Microsoft Excel, and LibreOffice Calc. Google Sheets demo is available upon request.
