What is VFC or HRV?
Visit Heart Rate Variability (HRV) is an increasingly popular health indicator in the healthcare sector. sport and well-being. But what exactly is VFC, why is it important and how can it be used to improve performance and recovery? We explain!
Understanding VFC (or HRV)
Visit Heart Rate Variability (HRV) measures time variations between each heartbeat. Unlike heart rate, which counts the number of beats per minute, the VFC examines the variation in time intervals between successive beats.
These variations are influenced by the autonomic nervous systemwhich regulates many involuntary bodily functions, such as breathing, digestion and heart rate.
For example, if a person has 60 beats per minute1 beat per second on average.
Visit VFC will measure the reality of the beat intervals, which will generally increase and decrease, going from 1 per second to 0.9 s, 0.8 s, 0.7s then 0.8 s, 0.9 s and back to 1s, 1.1s, 1.2 s, 1.3s then 1.2 s, 1.1s, 1s creating a acceleration and braking sinusoid averaging 60 beats per second over one minute.
Why is VFC important?
1. Stress and Fatigue Indicator
Visit VFC can be used to assess stress and fatigue. Reduced variations can signal that the body is under pressure, whether from physical stress, mental or emotional.
2. Recovery Management Tool
For athletes, the VFC is an invaluable tool for optimize recovery periods. By monitoring their VFCIn this way, it is possible to determine whether the body is ready for an intense workout, or whether it needs additional rest.
3. Cardiovascular Health Monitoring
Visit VFC is also used in the medical field to monitor the cardiovascular health and prevent heart diseases. A High VFC is generally a sign of good heart health.
How to measure VFC?
This can be done using a variety of technological devices such as connected watchesand heart rate belts or specific applications. Here are a few steps for measuring VFC efficiently :
1. Use a Reliable Device
Choose a device reliable and scientifically validated for measuring VFC. Heart rate belts such as the "Polar are the scientific benchmark. Many brands of connected watches also feature the "VFC measurement but to date, no brand has been accepted as scientifically valid.
2. Measure at Rest
To obtain accurate data, it is essential to measure the VFC in the morning. An initial measure of 5 minutes lying down and another immediately afterwards of 5 minutes standing up beside the bed. This provides consistent reference values for the central nervous system.
3. Consistency in Measurements
Visit VFC is measured regularly, at each survey, to track trends and identify significant variations.
Using HRV to Improve Performance and Recovery
1. Planning workouts
By monitoring the HRVIn addition, athletes can adjust their training program according to their state of recovery.
A High HRV may indicate that the body is ready for an intense workout, whereas a Low HRV can signal the need for rest.
2. Managing Stress
Monitoring the HRV can help identify sources of stress and implement strategies to manage them.
Relaxation techniques such as meditation or the yogacan improve HRV and overall recovery.
3. Optimize sleep
Visit VFC is closely linked to the sleep quality This is why reference measurements are taken in the morning on rising. Using the IAKOTA mattress toppera increased deep sleep time (30 to more than 50%), one lower heart rate and a positive effect on VFC rising. Visit IAKOTA mattress topper with a positive impact on the VFC and the deep sleephave beneficial effects on recovery and the performance.
Conclusion
Visit Heart Rate Variability (HRV) is a powerful tool for understanding and optimizing health and the performance. By integrating VFC into your daily routine, you can better manage the stressimprove your recovery and maximize your sporting performances.
