Cyclists’ resting heart rate
The resting heart rates of professional cyclists have always raised some suspicion. In the early 90’s it was leaked that Miguel Indurain had only 28 beats per minute. This information has never been accurately verified and continues to generate some debate to this day. The scientific and physiological controversy of knowing to what extent such low values can be healthy is still open and the truth is that the scientific and sports community cannot agree.
The case of the cyclist from Navarre is the most significant and Indurain’s resting heart rate has generated a certain «mythology» around it. So much so that Indurain’s body and stress test values are often used as examples of extreme sporting values.
All these adaptations are similar to certain cardiac transtrons, and sometimes they could be confused. What in a sedentary person could be considered a cardiopathy, in an athlete is something totally normal. In order to blur this fine line, medical and scientific personnel continue to work to improve their diagnostic capabilities.

Quantifying wristbands have become very popular devices not only among those who practice sports, but also among those who simply want to improve their physical activity through reminders and achievements that encourage them to perform simple tasks such as getting up and walking more often.
These products often feature heart rate sensors, a crucial element in the training of athletes who can thus check the limits within which the intensity of their workouts should move. The problem is that the accuracy of these sensors is in question, and it is necessary to know how they work and whether they really provide reliable information before placing all our trust in them.
Fitbit is currently the benchmark company in the wearables sector: IDC published a study a few weeks ago in which it indicated that the market share of this manufacturer is 43.9% – not counting Apple and its smartwatch with quantifier functions, for which it did not obtain data -, while Xiaomi, Samsung and Garmin also share this pie with similar results.
For the Getting Started with Arduino project series, we are using this kit. You will be able to have all the necessary components for all the practices in this series if you purchase the kit. Otherwise, you will be able to do the practices with the materials list below:
Note: When using buttons it is important to consider the human reaction vs. processor speed when pressing a button. That is, when we press the button and use a cycle to evaluate the state of the button, the processor can read up to 15 keystrokes depending on the time the user presses the button, this problem is known as «Debounce». So to avoid this problem the easiest way to solve it is to make a «delay» delay between states, which we can see in the code of Figure 2.

This is a difficult data to access because these values are usually reserved for doctors and cyclists themselves; it is not the most normal thing to find these values. We have found some references, but few to be honest, because as I said, these are not data that riders and teams like to report promptly.
Surely you all remember the famous data that, at the time, was published about Miguel Indurain. Miguel Indurain’s 28 beats at rest became a true paradigm of the perfect cyclist with all the talk that this topic gave…
For lovers of data and warning that these figures that we now offer are not official and have been collected from different websites, so we can not ensure that this is true to reality today. In any case, to serve as a guide we are going to give these data, which are those we have been able to locate from reliable sources:
