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.

Notes from a high-volume cycling training camp

Simon Wegerif shares his experience and tips following this years week long cycling training camp in Tenerife in the Canary Islands. The excellent paved roads extending from sea level to the main crater of Mt Teide at 2100m give continuous climbs of 18 – 48 km i.e. some of the longest in Europe.

Periodisation – A shake up to training adaptation theory?

The stress – adaptation response considered to underlie improvements in performance caused by training has hardly been questioned in almost 100 years. Now, a new and thought-provoking review paper questions the basis for this model, especially as it applies to human...

Individualised cold water immersion to speed recovery

Who, what and why? Coldwater immersion baths are often used to speed up recovery in both endurance and team sports. It is thought to be effective by moving fluid back from muscle tissue into the circulation, preventing reduction in contractility and associated muscle...

Simon’s Tenerife Training Camp

The plan The main objective of this camp was to get in some good base miles with an emphasis on climbing in preparation for my second year of the Mallorca 312 challenge. Living in the New Forest in southern England, the terrain barely meets the criteria for...

Science and Cycling 2016 – Summary of presentations

Science & Cycling is an annual gathering of researchers, expert practitioners and team performance managers arranged a couple of days before, and close to the start of the Tour de France. It was our first time attending and exhibiting and turned out to be one of...

Mallorca 312 – Event and post race recovery

In summary, I think the preparation for this event was a success – especially the many hours of MAF endurance training, and the aerodynamic improvements to both my position and the bike itself. I think diet was the only area I didn’t get quite right, and perhaps I need to gain confidence that I can perform on a low(er) carb diet on a 100m event first.

Training for the Mallorca 312. The final month.

I have now begun my taper, with just a week to go before the 312km event in Mallorca next Saturday. I’m already in the centre zone of the Pro Training Guide, and expect to move rightwards during the week as my recovery continues to improve.

Out and about with ithlete

The ithlete team have a number of events coming up so we wanted to share a short post letting you know where you can catch us!

Fat adaptation for exercise – how far can it go?

Despite a great deal of discussion about, and anecdotal evidence to support the benefits of a low carbohydrate high fat (LCHF) diet, there have been few studies examining the degree to which athletes’ metabolisms have been altered to take advantage of this dramatic change in fuel for exercise.

Preparing for the longest ride…

By Simon Wegerif Every year I have to do something that tests the limits of my endurance. Two years ago it was the Haute Route challenge of cycling from Geneva to Nice in 6 timed stages across the Alps, and last year it was the Etape TdF stage with 4500m of climbing...

How well does HRV reflect overall health?

Who, what and why? Heart rate variability, or HRV, has long been considered to reflect overall health. Since the 1980s, Professor Steven Porges described HRV as an index not only of stress, but of vulnerability to stress. In other words, the higher someone’s HRV, the...

Can HRV help detect concussion?

Who, what & why Traumatic brain injuries, such as concussion, are unfortunately an occupational hazard in many contact sports. As I write this, sad news was announced today that 23 year old rugby player Lilly Partridge had died following a head injury during...

Heat Stress and Sport

As the temperature increases, how well you deal with the heat will play a significant role in determining your sporting performance. This month’s hot topic looks at why it’s crucial that athletes of all abilities adapt to the heat and more importantly how best to do it.

Can your Morning HRV Predict your Cycling Performance?

Who, what, why? In two previous posts, we summarised studies that showed an almost unbelievable ability for night-time / morning heart rate variability (HRV) to predict the changes in performance of both swimmers and club runners. HRV and Swimming Time Trial Results...

ithlete at the Biohacker Summit 2015

Next week Simon Wegerif, Creator of ithlete will be speaking on a panel session at the Biohacker Summit in Helsinki, Finland discussing the future of wearable technologies for health & Wellness.

How accurate are consumer pulse sensors?

Not very – according to a review recently undertaken by CNET. Senior Editor Sharon Profis collaborated with Cardiologist Dr Jon Zaroff to compare some popular health tracker devices to medical ECG equipment at rest and during treadmill exercise at quite high...

HRV after exercise: implications for training prescription

Introduction Researchers Jamie Stanley & Jonathan Peake from the University of Queensland, with the guidance of heart rate variability (HRV) sports research supremo Martin Buchheit have put together an important review article with over 120 references. The paper...

Camp Digital user experience conference

Camp Digital We were invited to present at a User Experience event called Camp Digital in Manchester by the designer Chris Bush who helped us realise the v3.0 UI (user interface) design of ithlete. This was the first time I had presented to (several hundred) User...

This weekend we are off to Halle in the former Eastern Germany to present & exhibit at the 6th International HRV Symposium. This is a biannual event that consists of a full day program of both invited speakers who are authorities on particular aspects of HRV...

Breathing and heart rate variability: The Research

The impact of breathing on different HRV measurements: implications for monitoring athletes Who, what & why? It has long been known that breathing affects heart rate variability (HRV). Many studies have tracked HRV in athletes – some have used free (spontaneous)...

Simon’s Polarised Training Challenge: The results!

The Etape du Tour 2013 Sunday 7th July So was all the training and preparation worthwhile?  Read on to find out! Taper & travel After a couple of good rides the previous weekend, I began my taper with an hour long aerobic ride on Weds 3rd July, and a light workout...

Measurement of HRV

Early measurement of HRV Although irregular heart rhythms and their potential for predicting health outcomes had been noticed by Chinese medics all the way back to 400 AD, it really took the Nobel prize winning invention of the Electro Cardio Graph (ECG or EKG) by...
