Comprehensive blood test analyzing key biomarkers to optimize athletic performance and prevent overtraining.

Additional Information

This test helps endurance athletes understand their body's response to stress and training. It measures metabolic hormone function (including cortisol), inflammation, muscle damage, oxygen carrying capacity, and bone health. By analyzing these key biomarkers, athletes can fine-tune their training regimes for peak performance and avoid overtraining syndrome. The test also assesses essential organ function to ensure a solid health foundation for training.

Biomarkers Tested (68)
