HRV

Heart rate variability (HRV) is the physiological phenomenon of variation in the time interval between heartbeats. It is measured by the variation in the beat-to-beat interval.

For those who want some more of the science around it check out the below;

To understand HRV, we first need to understand our nervous system and heart rate. Heart rate variability can be traced back to our autonomic nervous system.

The autonomic nervous system regulates very important systems in our body, including the heart and respiration rate and digestion. The autonomic nervous system has a parasympathetic (rest) and a sympathetic (activation) branch. Heart rate variability is an indicator that both branches are functioning – the parasympathetic in particular.

Intrinsic heart rate is measured in the condition in which neither parasympathetic nor sympathetic regulation is present. When completely blocked from autonomic regulation, a healthy heart contracts at a rate of about 100 beats per minute (the number is individual, however).

Parasympathetic regulation lowers your heart rate from the intrinsic level, giving more room for variability between successive heartbeats. Parasympathetic regulation causes almost immediate changes that affect only a few beats at a time, after which the heart rate returns towards the intrinsic rate. Sympathetic regulation elevates your heart rate from the intrinsic level, and there is less room for variability between successive heartbeats. Sympathetic regulation affects several consecutive heart beats.

Put these together and we can formulate a rule that when the rest-related parasympathetic branch is active and the sympathetic branch is inactive, your heart rate is lower and HRV higher. Factors such as stress can lead to the withdrawal of parasympathetic activity, or activation of sympathetic branch even when you are resting, both leading to elevated heart rate and lowered HRV.

What are we looking at in regards to your HRV?

As mentioned, the autonomic nervous controls (ANS) controls all underlying bodily functions such as breathing, sweating, heart rate, impulses and much more…..

 

This information is key to assisting you in developing a prescriptive lifestyle plan that's tailored to your needs and creates a positive impact to your physical and mental wellbeing.

 

The health tech will aid in identifying the following key dynamic health markers (changes daily):

 

  • Heart rate variability - effects of ANS inflammation

  • R.E.M sleep - affects daily emotional recovery 

  • Deep sleep - affects daily Physiological recovery

  • Resting heart rate - Cardio-vascular status

  • Recovery - RHR + HRV + sleep quality outcomes

  • Strain - Positive or Negative- impact of exercise and stress on your HRV

  • Sleep - latency, disruption, time, and Light/deep/R.E.M/ analytics


Basically, the better your HRV, the better you will feel. More energy, more vitality, more mental clarity!

 

Our goal is to help improve your HRV from the baseline number you have. It's an individual journey!
