What is a good measure of heart rate variability?

The middle 50% of 20-25 year olds usually have an average HRV in the 55-105 range, while 60-65 year olds tend to be between 25-45.

Why is HRV important?

People who have a high HRV may have greater cardiovascular fitness and may be more resilient to stress. HRV may also provide personal feedback about your lifestyle and help motivate those who are considering taking steps toward a healthier life.

How is heart rate variability calculated?

It is calculated by first dividing the 24 h record into 288 5 min segments and then calculating the standard deviation of all NN intervals contained within each segment. The SDNNI is the average of these 288 values. The SDNNI primarily reflects autonomic influence on HRV.

Can you calculate HRV from heart rate?

The single most common way in which to analyse HRV is a time-domain method called RMSSD. This is the Root Mean Square of Successive Differences between each heartbeat. It is relatively simple to calculate (important for large-scale computation), and provides a reliable measure of HRV and parasympathetic activity.

What is a good HRV score for my age?

“What is a Good HRV Score for Me?” The average heart rate variability for all WHOOP members is 65 for men and 62 for women. For 25-year-olds it’s 78, for 35-year-olds it’s 60, for 45-year-olds it’s 48, and for 55-year-olds it’s 44.

What does low rMSSD mean?

CV rMSSD: A decrease associated with higher rMSSD and lower HR can be representative of coping well with training, while a decrease associated with lower rMSSD is probably representative of risk of non-functional overreaching.

What’s a normal HRV range?

Normal HRV can range anywhere from below 20 to over 200 milliseconds, depending on various factors such as age, gender, physical fitness, and genetics. The HRV value provided by Oura falls within this same range.
