The National Library of Medicine published a review (ref. link) of multiple longitudinal and cross sectional studies on HRV, concluding that “the cardiovascular system is mostly controlled by autonomic regulation through the activity of sympathetic and parasympathetic pathways of the autonomic nervous system”. This is significant because it means that accurate assessment of one’s HRV can give deep insight into this cardiovascular control mechanism.
In the past HRV was primarily used to predict sudden cardiac death as well as assess the progression of various cardiovascular and metabolic illnesses. That being said, recent studies are talking about the benefits it offers to physical training assessment. Today top athletes use HRV to analyse their training adaptations/maladaptations, and to set up appropriate training loads to improve their performance. So, let’s look into HRV to learn of the benefits it offers both athletes and non-athletes.
What is Heart Rate Variability (HRV)?
Heart rate variability (HRV) is the measurement of the time interval between consecutive heartbeats. It is a non-invasive and inexpensive method to assess autonomic nervous system (ANS) activity, which controls our heart rate, breathing, and digestion. HRV is influenced by both sympathetic and parasympathetic branches of the ANS, and the balance between these two branches is critical for optimal health and performance.
How does HRV Monitoring benefit Athletes?
HRV as a training and recovery monitoring tool–
HRV monitoring can help athletes to optimise their training load and recovery. HRV is sensitive to changes in training load, and a decrease in HRV can indicate that an athlete is experiencing fatigue or overtraining. By monitoring HRV, athletes can adjust their training load to prevent overtraining and ensure that they are recovering adequately between sessions.
Intensity of athletic training–
The heart rate varies depending on the body’s physical needs. In athletes, the sympathovagal balance keeps changing based on the duration and intensity of sports training. Studies revealed how the sympathetic and parasympathetic tones of nervous systems vary between relatively less intense and more intense exercises. These measures help in finding out the intensity of training and to eventually find out the effectiveness of training.
Identify Early Signs of Illness or Injury For On-Time Treatment
HRV monitoring can also help athletes to identify early signs of illness or injury. A decrease in HRV can be an early indicator of an impending illness, such as a cold or flu, or an injury. By monitoring HRV, athletes can catch these issues early and take steps to prevent them from becoming more serious.
Improve Mental Toughness
HRV monitoring can also help to improve their mental toughness in athletes. HRV is influenced by stress, and learning to control HRV can help athletes to manage stress and anxiety more effectively. By using HRV biofeedback training, athletes can learn to control their HRV and improve their mental toughness.
Benefits of HRV Monitoring for Non-Athletes
Studies state that a low heart rate variability could be a sign of a variety of underlying health problems.
Assess Overall Health and Wellness
HRV monitoring can be used to assess overall health and wellness in non-athletes. HRV is a sensitive marker of autonomic nervous system activity, and a decrease in heart rate variability has been associated with a range of health issues, including heart disease, diabetes, and depression. By monitoring HRV, non-athletes can assess their overall health and wellness to take steps to improve it if necessary.
Better Stress management
Stress can affect your health. HRV monitoring tracks changes in your stress levels, so you can identify when you are stressed and take steps to effectively manage it. By regularly monitoring heart rate variability, you can find how your body responds to stress and make the required lifestyle changes to contain it.
Improved Sleep Quality
Sleep is the best medicine for maintaining overall health. The problem is that people may have trouble sleeping, or experience broken or disturbed sleep due to their busy lifestyle. HRV monitoring can also be used to enhance sleep quality in non-athletes. A high heart rate variability means better sleep while a low HRV usually indicates a problem.
Enhanced mental health
A high heart rate variability means better mood and health. On the other hand, a low heart rate variability can lead to mood disorders like anxiety and depression. Monitoring HRV can help you track when you have mood swings and take steps to get it treated for better mental health.
You can consult your healthcare professional to know how heart rate variability works for you and take necessary steps to lead a healthy and active life.
In short, monitoring Heart Rate Variability regularly can help you improve your athletic performance, keep your stress levels low, improve your sleep and help you lead a healthy life. Finally, the best way to monitor your HRV data accurately is by using a smart heart monitor. The Frontier X2 gives you access to a number of heart health metrics including HRV, so that you can put your best foot forward as you strive to improve your cardiovascular health.
It is important to consult your doctor if you see a consistently low HRV and take proper treatment for better health.
HRV can be measured using a heart rate monitor and a smartphone app, or a dedicated HRV monitor. These devices use a mathematical algorithm to analyze the variation in time between consecutive heartbeats.
There is no specific normal range for HRV, as it varies depending on a person’s age, gender, and fitness level. However, a higher HRV generally indicates better health and wellness.
Yes, HRV can be improved through various lifestyle changes and interventions, such as exercise, stress reduction techniques, and improving sleep quality.
No, HRV monitoring can be beneficial for both athletes and non-athletes. While athletes may use it to optimize their training and recovery, non-athletes can use it to assess their overall health and wellness, improve stress management, and enhance sleep quality.
HRV monitoring is generally considered safe and non-invasive. However, it is important to consult with a healthcare professional before starting any new exercise or wellness program. In some cases, HRV monitoring may not be appropriate for individuals with certain medical conditions.
