# IMPORTANT INFORMATION To use the **Historical Analysis** and **AI Calculation/Correction** features, a small donation to **med4hope** is required. (mailto: [email protected] more informations needed?) The donation verification system will be activated on **July 11**. Until then, you can use the **full version without a license** free of charge. After July 11, simply make a donation of **at least €2** to **med4hope**, and we will send you your personal license code. Please send your license request together with your donation confirmation to: **[[email protected]](mailto:[email protected])** --- # Adaptive Lactate Estimation Model for Garmin Connect IQ ## Project Objective The goal of this project is to develop a **real-time lactate estimation model** for cycling that provides the most realistic possible estimate of an athlete's current blood lactate concentration without requiring continuous blood sampling. The model combines multiple physiological parameters, including: * Power output (watts) * Heart rate * Continuous glucose monitoring (CGM) data * Anaerobic workload above the individual lactate threshold * Time-based physiological smoothing * Individual calibration using actual blood lactate measurements Through repeated calibrations, the system continuously adapts and evolves into a highly personalized metabolic model that reflects the athlete's unique physiological response, energy metabolism, and lactate kinetics. The long-term objective is to achieve the highest possible estimation accuracy by continuously learning from each athlete's individual training and calibration data.
