Hypertension Theraphy

Heart rate
Among the cardiovascular changes observed a decrease in heart rate (heart beats per minute) at rest and during performance of a submaximal exercise intensity, no perceptible changes in heart rate usually peak with training. That is, the same mechanical stress (eg running at 12 km / h) before training could make an effort for the agency regarding heart rate of 140 beats / min. and after 4 weeks of aerobic training lead 130 bpm. Undoubtedly it is a positive development and improved cardiovascular fitness. The heart rate therefore is a parameter easy to measure, which quantifies in a practical and real intensity cardiovascular exertion level. Their knowledge allows us to objectify the intensity of exercise and prescribe training loads based on this parameter. Also we carry out a transfer of the effort in Ergometries (stress tests performed in the exercise physiology laboratories) to the sporting arena. For this reason, more and more often, athletes in their training and competitions, mainly endurance athletes, who use heart rate monitors, telemetry, allow them to know at any time heart rate.

Blood Pressure
The numbers decrease blood pressure at rest and during exercise increases experienced milder than in untrained subjects, so that the product of systolic blood pressure by heart rate, a rate which is subject to overload the heart, decreases.

Aerobic exercise is recommended as adjunctive therapy in mild-moderate hypertension, along with hygienic-dietary measures such as low salt diet, weight loss if overweight and stress management. These are initial steps before considering drug treatment of hypertension. Aerobic exercise produces vasodilation which tends to decrease peripheral vascular resistance and thus decrease diastolic blood pressure during exercise. In any case, a person with a light-moderate hypertension is indicated before the exercise prescription conducting a stress test to evaluate the response of blood pressure.

Size of heart chambers
Another interesting adaptations that occur as a result of cardiovascular level aerobic, dynamic, long-term, is related to the size of the heart chambers, which increase by improving the filling capacity increases as the cardiac output. The heart walls are somewhat thicker than in the non-athlete population. Overall, the heart grows in a harmonious way without imbalances between the volume of the cardiac cavities and wall thickness.

Increased stroke volume
Another important adaptation is the increased heart stroke volume or stroke volume, ie the amount of blood ejected from the heart every time collapses. This increase occurs at rest and during submaximal and maximal exercise. Therefore the amount of blood ejected from the heart each minute (cardiac output or stroke volume) that depends on heart rate and stroke volume also increased significantly to make a maximum effort without experiencing changes in rest or by perform submaximal exercise.
