In rest conditions, the number of beats per minute generally fluctuates from a minimum value of 60 to a maximum value of 100 beats. However, there is a wide inter-individual variability in resting heart rate values.
The minimum values (around 35bpm) are recorded in professional sportsmen dedicated to the practice of basic disciplines, such as cycling, walking and running. Not by chance, until 2004 the book of guinness attributed the primacy of " minimum heart rate value at rest (in a healthy person)" to the former Spanish cyclist Miguel Indurain, winner of 5 tours de France in the early 90s .
In 1995, at the Chest and Heart Unit in Guernsey, the cyclist Navarro recorded a value of 28 beats per minute.
In 2005, at the age of 35, the Englishman Martin Brady, however, ousted Indurain from the Guinness Book, registering a value of 27 beats per minute in the same clinic.
