Physical activity combats hypertension

It is not a novelty. Indeed, is already a fact well proven. The cardiofitness, namely physical exercise can push up the performance of the cardiovascular system, exerts beneficial effects in hypertension.

And in mild forms, with pressure values somewhat higher than 140/90, which doctors define as "frontier" may even blood pressure returned to normal values, without having to take pills. Numerous studies have shown that aerobic exercise characteristic of cardiofitness causes a decrease in blood pressure maximum and minimum sleep.

The mechanisms by which this effect occurs are partially known. For example, aerobic activity determines an increase of the capillary network of muscles in the periphery: in this way the same blood flow is distributed in a "tree" bigger and low pressure. Secondly, sport moderate influence on the system of endocrine glands.

What does? Decreases catecholamines, stress hormones that cause the narrowing of blood vessels peripherals, play an important role in the onset of hypertension. However, while making sport benefits the tension, it is essential to choose the appropriate discipline, and to establish accurately the intensity, frequency and duration of effort.

The physical activities more suited to normalize the pressure are jogging, race, swimming, running, walking, cycling and cross-country skiing. And when, during the winter, cardiofitness exercises must be conducted indoors, in the gym is available a wide range of appliances such as treadmills, exercise bikes and step.

Semaphore red, however, for sports that involve anaerobic efforts (as in the shorter sprint distances, the shot put and body building). In any case, to obtain the maximum benefit, exercise should dosificarse with extreme caution, as if it were a drug, because it can be
dangerous, a kind of double-edged sword, if performed without judgement.

The program of physical activity, for example, may include 40 or 50 minutes of training, three or four times a week. What pace should continue? Surely we must avoid the high intensities. The exercises are the most effective light. Experts agree that, ideally, consider keeping the heart beats 60% or 70% of the maximum heart rate, better determined in laboratory with a traditional stress test, rather than with the classic formula '220 - age. "

The most rational and safe to control the intensity of physical activity to which we are dedicating Pulsómetro is to make use of. This device provides a continuous and reliable information about the heart's response during the effort, avoiding the risk of working at levels of heart rate too high regarding the scheduled by the cardiologist.

The Pulsómetro is a perfect guide when it should be very accurately assess performance and maintain control under the regime of training. It also allows control the heart rate and alerts with programmable alarms when they are exceeding the preset values.
