Where ithlete began

Founder Simon Wegerif explains in his own words how ithlete was designed in response to an athlete’s genuine need to train smart.

Like many endurance athletes – runners, cyclists and triathletes – I used a heart rate monitor. It helped me measure how hard my body was working during training as well as keeping me just to the right side of the red line during competition. Since I wasn’t getting any younger and I liked to keep pace with the top local, and yes, younger riders, I began investigating smarter training methods that would improve my performance but without the risk of injury due to overtraining. This is how I found out about heart rate variability (HRV).

In time, I became convinced that I needed to incorporate HRV as part of my own athletic training. So I looked around to see what commercial products were available and came to the conclusion that there was not an easy-to-use, affordable product that could give a direct and daily measure of HRV together with visual aids to interpretation such as traffic light training indicators and trend charts. But all was not lost. As an engineer by profession, building an HRV system did not seem particularly daunting.

My device had to be scientifically valid, practical, and uncomplicated to use.
During 2009, I read over 500 research papers on HRV and consulted with many experts, cardiologists, coaches and trainers. My device had to be scientifically valid, practical, and uncomplicated to use. During this research, and following patent applications in the US, UK and EU, I was subsequently invited to establish sports and medical research collaborations on HRV application in cardiac rehabilitation and elite sports training.

Since this time I’ve continued to follow the latest heart rate variability (HRV) scientific studies and papers ensuring that ithlete follows current best practice.

Development and progression
HRV Fit Ltd. is committed to continuous development of the company and all of our products – sensors, mobile and web apps. HRV Fit has also created custom variations of the patented ithlete application for trainers in specific sports. We have supplied custom apps and hardware for corporate wellness initiatives such as the Federally approved Moove program in Germany, and ithlete is currently involved in trials research and clinical trials.
