To counteract this and clear waste, the heart rate increases proportionally to the intensity of the work. Fatigue and heart rate are deeply intertwined physiological signals that reflect the current state of your body and mind.
Zone 4: Threshold Near max, 80-90% of max High risk of burnout and requires careful monitoring. Understanding the relationship between these two factors is essential for optimizing performance, managing stress, and protecting long-term health.
