HRV and Covid – Training during and after infection
During the early part of the pandemic, in June 2020, ithlete won a grant to try and determine whether or not changes in daily HRV could be used to detect the onset and subsequent severity of the illness. What we didn’t know about at the time we conducted the survey of ithlete users, was how Covid would affect an otherwise healthy athlete’s ability to train during the illness and subsequent recovery.
Let’s take another look.

How does your HRV vary throughout the day, and why does it matter what time of day you take an HRV reading?
We recommend you take your Heart Rate Variability (HRV) reading at the same time of day – just after waking up and before drinking tea / coffee or checking your emails and social media. But why does it matter what time of day you take an HRV reading, and why can’t you compare a reading taken in the morning with one taken after lunch or in the evening?

Want to know more about ithlete?
Follow these four easy steps to get started with ithlete today!
Choose a heart rate sensor
To measure heart rate variability (HRV) with ithlete you’ll need a heart rate sensor. You have the option to use an ithlete finger sensor or chest strap monitor. If you have a recent iPhone, iPad or Android device you may like to use our Bluetooth Smart chest strap monitor, or alternatively grab a Polar type analogue strap (we also offer one of these) and an ithlete ECG receiver to pick up the signal. Visit the ithlete store to find your preferred sensor.
Download the ithlete app
ithlete is available on both iOS and Android devices and can be downloaded from the App Store or Google Play. If you do want to check your model of smartphone or tablet is compatible check our FAQ page.
One minute daily measurement
After waking each morning relax and sit comfortably, slip on a chest strap or finger sensor and follow the on screen instructions to get an accurate reading of your heart rate variability. Taking the measurement couldn’t be simpler and in 60 seconds you will have a personalised training recommendation for the day.
Reap the benefits of training with ithlete
The idea is quite simple. Training is all about stress and recovery. A hard session, lack of sleep, mental stress etc. will lower your number. If your reading drops significantly, take this as an early warning that you are overloading the system. On the other hand a high score lets you know you should make the most out of the day. Benefits of this include avoiding overtraining, workout optimisation, guilt free rest days, improved performance and much more!
