Master Exercise Thresholds with AI Precision
Learn, practice, and analyze exercise thresholds using cutting-edge AI technology. Identify respiratory-based exercise intensity thresholds with confidence, guided by Oxynet - our deep learning system trained on expert assessments.

What is Oxynet?

Oxynet is a cutting-edge deep learning system that automatically detects exercise thresholds with expert-level precision. Using advanced neural networks trained on hundreds of cardiopulmonary exercise tests from diverse populations (from chronic heart failure patients to trained distance runners), Oxynet provides objective, reproducible threshold identification in real-time.

Key features of Oxynet include:

  • Instant threshold detection: Get automated identification of respiratory-based exercise intensity thresholds in seconds
  • Expert-level accuracy: Trained on over 1,600 cardiopulmonary exercise tests analyzed by experienced exercise physiologists
  • Confidence scores: Receive probability estimates for each threshold to guide your clinical and research decisions
  • Educational tool: Compare AI predictions with your own assessments and expert annotations to enhance learning
  • Research-validated: Performance validated in peer-reviewed research with mean bias <50 mL·min-1 compared to expert consensus

Coming in our next publication: Our research demonstrates that Oxynet performs comparably to expert consensus in identifying respiratory-based exercise intensity thresholds, with the added benefits of objectivity, speed, and standardization. This technology represents a breakthrough in exercise physiology, combining deep learning with pedagogical best practices for both clinical and educational applications.
