Finding the heart rate monitor device number

Each heart rate monitor has a unique identifier built-in. The identifier is a number that it is uniquely assigned to a heart rate monitor.

The device number must be associated with a user. Once the association is made, every time a person will wear that heart rate monitor, our application will automatically recognize him. This must only be done once.

Finding the Heart Rate Monitor Device Number

Our cloud services make it easy to manage the associations and keep your data safe. All your data in our cloud services are backed up. If you change or break your device you can easily recover all your data with the press of a button.

Further Insights using the Critical Power Analysis

Athletes and coaches are used to analyze the so called Critical Power (CP) curve. The CP curve shows the power an athlete can sustain for a certain period of time. For example a CP5 of 500W means the rider was able to sustain an average of 500W for 5 seconds as its best performance in all his rides. See our previous post Analyze your power output.

Today, we have added an additional metric to the CP analysis, that is the average heart rate during that effort. The heart rate metric adds an additional insight and quantifies the impact of that effort on the body.


The Critical Power analysis can be used with bike power, rowing power and running power.

At equal power performances, the lower heart rate highlights an athlete in a better shape and form.

With the Peak Power Evolution line chart, it is possible to follow the evolution of each CP line (CP5 seconds,CP10 seconds,etc.) and how the power and heart rate evolve with time. The range period can be selected.


We believe this is an additional advanced analysis that can be used to help athletes improve and reach their potential.


Real Time calories on the screen

You have asked, we have implemented it. Calories are now shown on the main screen during a session. To enable this functionality, make sure you enable “recording” and that each user has been registered with an email address.


Alex Zanardi, a great inspiration for us

Alex Zanardi has won a gold medal at the latest Rio Paralympics 2016. But it is not the victory that we want to highlight here but the man and his story.
Alex was a successful Formula 1 driven that lost both his legs in a tragic accidents while racing. He did not give up. He was determined to continuing his life.

Some quotes from Alex after the gold medal (excerpts from this BBC article):
“When you find yourself in a certain situation you have to identify where you want to go and focus on what you can achieve on that given day. Whether it is a small thing or big one, step-by-step you can make things happen.

“At the time I was asked if I would ever step back in a race car, but what was very important for me was to go into the bathroom and pee on my own, but I could not do that. I had to be helped. That was my number one priority. Day by day I managed to regain control and strength, regain some confidence and concentrate on different things and here I am now.”

Rowing and Working out with Selfloosp

The Group Fitness Premium works with Concept2 rowers, skiErgs, bike power sensors and heart rate monitors.

The application tracks real-time data and shows group sessions on a tablet screen or an external larger screen.

Tiles can be colored according to target, such as distance, power, or calories.

Post analysis of the workout is available in the Selfloops website.

The service can be used for competitions and trainings, providing real-time data allowing personalized feedback to the athletes.

Personalized: Log in before the session and the SelfLoops cloud ensures a personalized training experience.

Post workout analysis: At the end of the session, data are automatically uploaded in the SelfLoop website, ready to be visualized and analyzed.

Coaching your athletes: As a coach you can manage the users, visualize their performance and give feedback thanks to our team management platform.



100 Miles of Nowhere with the Selfloops telemetry


The 100 Miles of Nowhere is a unique event in South Africa. It is an indoor cycling challenge where participants have to complete 100 Miles = 160km on a stationary bike. An arduous task that takes from 4hrs to 6hrs to complete. The event is hosted by Cadence Cycle studios powered by Selfloops.

For the event, Selfloops has enabled the real-time telemetry across the 6 different locations involved in the event.

This means it will be possible to follow the event live from anywhere around the world using just a browser.
