Summary
This study introduces free software to calculate blood lactate markers, essential for assessing athlete endurance. The tool aids sports scientists in predicting and comparing endurance ability using key performance indicators.
Area of Science:
- Exercise Physiology
- Sports Science
- Biophysics
Background:
- Blood lactate markers quantify an athlete's physiological response to exercise.
- These markers, often near the lactate curve's inflection point, predict endurance capacity.
- Current methods lack accessible, free software for calculating these crucial metrics.
Purpose of the Study:
- To introduce novel, free software for calculating various blood lactate markers.
- To provide sports scientists with a tool for individual and squad performance analysis.
- To facilitate objective assessment of endurance ability based on lactate kinetics.
Main Methods:
- Development of a user-friendly software application.
- Implementation of algorithms for calculating established lactate markers.
- Validation of software against existing theoretical models and data.
Main Results:
- The software accurately calculates multiple blood lactate markers.
- It enables analysis of individual athletes over time and across a squad.
- Provides a free, accessible solution for sports scientists.
Conclusions:
- The developed software addresses the need for accessible tools in sports science.
- It enhances the ability to monitor and predict athlete endurance using lactate markers.
- Facilitates data-driven training and performance evaluation for athletes and teams.
