Biochemical Markers of Performance

Biochemical markers of performance are specific substances in the body—measured through blood or other fluids—that provide insights into an individual’s physical state, fitness, and recovery. They help assess how well the body is adapting to training, indicate levels of stress, fatigue, or overtraining, and can inform personalized training adjustments. These markers include hormones, enzymes, and metabolites that reflect muscle damage, energy use, hydration, and overall health. By monitoring these, athletes and trainers can optimize performance, prevent injury, and ensure effective recovery.
