Heart Rate Variability (HRV)

Heart Rate Variability (HRV) reflects the variation in time between each heartbeat and is a key metric for understanding how your body is adapting to your workouts. For consistency, HRV is measured during sleep. Higher HRV generally indicates that your body is recovering well from exercise, while lower HRV may signal stress, fatigue, or illness. Tracking HRV trends allows you to see how your training affects recovery, helping you adjust your intensity and avoid overtraining.

To improve your HRV, engage in regular physical activity, manage stress through relaxation techniques, get adequate sleep, and maintain overall good health through a balanced lifestyle.

Ranges

• Elite: You have an exceptionally strong cardiovascular system, often seen in top athletes. Your heart is highly efficient at pumping blood.
• Fit: You have good cardiovascular fitness, and your heart works efficiently at rest.
• Active: Your HRV is normal for someone who engages in regular physical activity but could be improved with more consistent cardiovascular exercise.
• Casual: Your HRV is lower than average, which may suggest a need for more activity or lifestyle adjustments to boost your cardiovascular health.
• Inactive: A lower HRV in this range can indicate low fitness levels or potential health concerns, signaling that improving your fitness could greatly benefit your health.
