HRV and Covid – an ithlete user’s perspective

Covid is still in the news, but mostly because of the revelations about Matt Hancock’s WhatsApp messages. Otherwise, you might get the impression that Covid has gone away.  I work in the NHS.  Until a few weeks ago I was required to undergo a lateral flow test twice a...

HRV and Understanding Illness

Using ithlete to measure HRV and predict or understand illness and guide a return to training by Janet Birkmyre I suppose that most of us will have thought a little more about the effects of viral infection on our health and training over the past couple of years,...

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 To Handle An Unexpected ithlete HRV Reading

by Jan Birkmyre Thanks to ithlete I have been tracking my heart rate variability (HRV) via a reading taken every morning since 2012.  It is so much a part of my routine these days that it sets the tone for my day.  Using the ithlete Pro version of the app I can track...

HRV, Life Stress and Training

by Janet Birkmyre ithlete’s HRV measurement turns training data into intelligence – it adds value by personalising data that (while being based on solid research) is otherwise too generic to allow for optimal decisions about training to be made when the human...

HRV and COVID-19 in athletes. Is there a connection?

We have been asked by the UK Government to test the hypothesis that HRV may be a powerful diagnostic tool for Covid-19. This article will explain the relationship between HRV and Covid, focusing particularly on the implications for people who exercise regularly and...

Lockdown Heart Rate Variability (HRV)

by Jan Birkmyre According to my daily heart rate variability (HRV) readings from ithlete, it is very clear my body loves this lockdown.  On reflection, I suppose, that should not come as a complete surprise but even so, the magnitude of the improvement is a shock....

Top tips for using your HRV sensor

The ithlete sensors are the best around, independently validated for accuracy, convenient and durable. Some users don’t get the hang of taking measurements right away, so to ensure you don’t waste any time follow the tip tips found here.

Time of measurement

Time of measurement We recommend taking your ithlete heart rate variability (HRV) reading first thing in the morning, preferably right after waking. There are several reasons behind this recommendation… Following a full night of rest It’s a well-known fact that the...

Can HRV predict changes in performance in swimmers?

Research performed over several decades has shown that when performed regularly aerobic exercise increases heart rate variability (HRV). Studies, such as this one, demonstrated that changes in HRV have corresponded with changes in performance brought about by training...

Are you Inflamm-Aging well?

What is inflamm-aging? And what can you do to ensure you’re inflamm-aging well? A reseaarch summary of the origional paper and how tracking HRV relates.

5 ways to improve Heart Rate Variability (HRV)

Heart Rate Variability (HRV) is an excellent measure of overall health and fitness. Upward trends have consistently been shown to correlate with increases in health, fitness and sporting performance. So how do you get your baseline rising?

What makes ithlete special?

ithlete has been copied by many imitators since 2009, but as we continue to develop and innovate no one competitor has achieved the combination of easy to access ithlete’s features and benefits.

Detecting Chronic vs Acute fatigue in Mountain Athletes

We recently came across an article highlighting difficulties when trying to identify chronic fatigue using HRV. The authors graciously gave us the opportunity to reply, which is now is part of the revised article, and here are our final thoughts.

Fatigue – is it all in the mind?

Who, what & why? Everyone reading this will be familiar with the sensation of gradually increasing effort to maintain the same pace whilst running or power output whilst cycling or rowing. But what exactly contributes to this sensation? And what can we do (safely)...

Better is Better

Like so many coaches out there, I’ve coached a fair share of athletes who subscribe to the “more is better” mindset.  Over my years in the endurance world, I’ve definitely learned to subscribe to the “more is not better; better is better” philosophy.  Why?  Because...

HRV response to breathing thin air

From a practical perspective, measuring your HRV at altitude and comparing to HRV at sea level can show how sensitive you are to the effects of altitude, and that if you are an elite level endurance athlete, you may be more sensitive than mere mortals! Here is the research.

The effects of overreaching on trained cyclists

Most endurance athletes are familiar with the term ‘overreaching’. That’s when you do high volumes of intensified training to cause supercompensation. But what actually happens to your body and what measures can you use to identify when overreaching has gone too far and become unproductive?
