What the heck is HRV and why should I care?
A little over a month ago I started doing some extensive research on the buzz word of fitness training in 2019, HRV or heart rate variability. There are a lot of devices on the market that say they measure HRV and at the time I had one, the series 4 Apple Watch. I was disappointed in what the capabilities of the Apple Watch could do in regards to the HRV measurement. I noticed the HRV measurements were consistently all over the place and taken at different times during the day. Frustrated with this important fitness reading I pulled the trigger on the WHOOP 3.0 device.
Heart rate variability (HRV) is a measure of your autonomic nervous system and is widely considered one of the best objective performance measurements for physical fitness and determining your body’s recovery. Scientifically HRV is the changes or variations that occur between successive heartbeats. The variability between heartbeats acts as a proxy for assessing an athletes autonomic nervous system function, and in particular the balance between the sympathetic and parasympathetic systems.
Things that affect HRV
- Sleep Quality
- Hydration Levels
- Prescription Drugs
- Alcohol and Caffeine
