Heart Rate Variability (HRV) Basics

Heart Rate Variability (HRV) is the variation in time between successive heartbeats, which is measured by the variation in the beat-to-beat intervals. HRV is affected by the balance between the sympathetic and parasympathetic branches of the autonomic nervous system, which regulate the heart rate and other physiological functions.

Garmin calculates HRV by analyzing the time between successive heartbeats, and then uses a proprietary algorithm to determine the level of stress. The HRV Stress Score is calculated by analyzing the beat-to-beat intervals during a 3-minute test, during which the Garmin device analyzes heart rate variability to determine overall stress. The stress score range is from 1 to 100, where 1 is a very low-stress state, and 100 is a very high-stress state.

Garmin also provides HRV Status, which is a measure of the balance between sympathetic and parasympathetic activity. HRV Status is calculated based on the user’s 7-day average HRV, and is displayed as either Balanced, High, or Low. If the HRV Status is Balanced, it means the user’s 7-day average HRV is within the normal range. If the HRV Status is High, it means the user’s 7-day average HRV is higher than normal, indicating a more relaxed state. If the HRV Status is Low, it means the user’s 7-day average HRV is lower than normal, indicating a more stressed state.

It is important to note that HRV is affected by many factors, including exercise, sleep, nutrition, and general life stress. Therefore, it is important to interpret HRV measurements in the context of other factors that may be affecting stress levels. Garmin recommends using HRV measurements as a tool to help manage stress and optimize training, but emphasizes that HRV should not be used as a diagnostic tool for medical conditions.
