Sport and heart health: the heart rate monitor, the precious purchase

To find out if you exercise at the right intensity, there is a magic watch: the heart rate monitor. This small device remains a subject of contention between doctors: some consider it a gadget, others think it is a useful assistant to control performance. What is it?

Sugars and fats are the fuel of our muscles. The heart is the motor of the body - it circulates blood and regulates oxygen. The mechanism is quite simple: in case of effort, breathing accelerates to bring more oxygen. The heart then accelerates the pace to increase the amount of circulating oxygenated blood. An example: at rest, we consume 30 to 35 milliliters of oxygen on average per kilogram per minute. In case of long-term effort, this consumption can reach 80 milliliters, or about two and a half times the usual amount. We have an engine that constantly knows how to adapt according to the demand ... Up to a certain limit, that each individual has difficulty to appreciate with accuracy.

Shortness of breath is a bad marker, at least not very accurate. But, we will never repeat it enough, nature has given us a very precise tachometer: the rhythm of our engine. This is called the heart rate, which gives the speed at which the heart beats. In healthy adults, at rest, the heart rate is between 50 (endurance athletes) and 80 beats per minute, but rises in case of stress, stress or emotion where there, it can happily cross the 100 barrier.

Paradoxically, while one might think that his needs are higher, the hearts of great sportsmen are slow. 30 to 40 beats minutes for a marathoner, less than 60 for someone who practices physical exercise several times a week. It is, then, beats of great efficiency, with a heart muscle that contracts thoroughly and plays its role of pump with power. The economy of beat, while producing an excellent circulation, makes it possible to face a brutal demand, much higher than normal.

So you have to know how to control your pulse and, if the maneuver is not complicated with a simple stopwatch looking for the beats at the wrist, it is not easy to do, often, in especially at the moment of the effort.

Electronics to the rescue

As for vehicles, electronics has come to the rescue of the bad appreciation of some humans. The heart rate monitor, a watch worn on the wrist, receives information from an emitting belt worn on the skin, at the chest. By measuring cardiac pulsations, the cardio frequency meter makes it possible to know if the limit is not exceeded and especially to manage the two main objectives of the physical exercise: to eliminate fat and to improve the performance of the cardiovascular system.

Maximum frequency during exercise

Without training, it is not advisable to go beyond 220 beats per minute minus his age when of an effort. This is called the maximum exercise frequency. This watch is also equipped with an alarm that prevents, from the limit crossed. This must remain theoretical, because the effort that will allow to burn fat, is at a pace much lower than this one. All the notes that accompany this small instrument allow you to program the zone that corresponds to your motivation; the one during which the fats are melted, while manufacturing muscle and the one that helps maintain the mechanics of the heart and the vessels.

Last argument, we find this "tachometer of form" at quite reasonable rates for entry-level. Internet sites giving all prices and details of use are legion on the internet. The simplest devices are often the most effective. Most, outside the heart rate, also give the number of calories burned, the average heart rate during exercise, but also, for the most sophisticated, the distance (using a GPS), the altitude, barometric pressure ...

Unlimited information, often useless!

Physicians' advice for practicing physical exercise is usually a bit minimalist, especially in the name of the famous precautionary principle that governs all medical advice. It must certainly be repeated that nothing replaces the medical examination at the slightest psychological doubt or motivated by an imperfect physical state, but this does not prevent most doctors from lacking precision in the prescription of physical exercise. The heart rate monitor is there to avoid some errors and promote the achievement of the goal.

To know more : Prescribe finally the physical exercise

This is obvious from all the specialties of medicine: physical exercise can be considered as a free universal drug, effective, almost without contraindications and side effects. It is obvious too: the message does not pass. Probably due to confusion sports / exercise that disrupts understanding and limits prescriptions. For the last twenty years, the term Adapted Physical Activity has been used to summarize all physical activities, even artistic ones, to arrive at a refund.

Health Insurance does not make it - wrongly - a priority. Also, doctors are reluctant to formalize a prescription. Define the "prescription card" of this essential therapy will be the purpose of the show below. The guest is a major player in the subject. Professor Gérard Saillant is known worldwide for having operated, as head of the orthopedic department of La Pitié, the greatest sportsmen on the planet. He is still one of the most consulted specialists for his expertise. But he also decided to devote most of his time to this new fight: that physical exercise is prescribed at the height of its effectiveness to participate in some form of rescue by moving its inhabitants.
