It has long been observed by doctors that the state of the cardiovascular system of sportsmen differs from that of persons who are not involved in sports (zafa testonon). First of all, themselves drawn attention to decrease in heart rate in athletes, this fact has long been considered a sign of high functional capacity, Testosterone Propionate. At present, this fact is not measured so simple, modern achievements of sports cardiology allow a deeper understanding of changes in the heart and blood vessels in athletes under the influence of physical activity.
Professional sports is not considered in itself is now uniquely useful, good, and injury is the result of a different mode of distribution of physical activity over time, Testosterone Propionate ie, It depends on the load intensity. People who train with high intensity, doing this is clearly not for the health effects, and to achieve sports results. At the same time, in the history of world sports events are sudden deaths of professional athletes on the external overall health. Modern sports medicine has proved that it is the physical exercise have caused these cases (risk of sudden death in athletes is much higher), legal Testosterone Propionate. Often athletes are not aware at any cardiac disease. This disease can only manifest itself incomprehensible malaise and decreased athletic performance. In other words, the sport was not only useful, but also harmful. It is because of these reasons, the American College of Sports Medicine recommends that the load for the purpose of rehabilitation, constitute 40% of the maximum allowable under the age of the account. About 20 years ago, these indicators were equal to 70%, but then gradually declined. Of course, the Americans provide the following figures, based on the achievements of modern medicine, and proven facts. Do not take this data uniquely, Testosterone Propionate rushing from one extreme to another, because the sport is still there, and reasonably calculated exercise are beneficial to health. Physical activity of low intensity positively affect the cardiovascular system, while prohibitive load or a complete lack of benefits are not. Modern professional athletes are very attentive to your body, to any change in its shape, so the author considers it necessary to inform them about testosterone isocaproate the ongoing processes in the cardiovascular system.

Heart condition in athletes, as has been said, is different from the persons who are not involved in sports. There are two variants of the heart condition of an athlete ( “athlete’s heart”):
-heart is more workable, that able to meet as a result of systematic training high demands placed upon it during long and intensive physical work, Testosterone Propionate ;
-heart pathological changes as a result of a sporting nature of excessive stress (GF Lang).
Often it is very difficult to decide where the norm, and where pathology. Changes in the heart and blood vessels are dependent on the type of load and its intensity, and systematic training, Testosterone Propionate for sale. The strength of the heart muscle contraction is regulated by at least two ways without the central nervous system.
The first method – the law Starling. These researchers found that the strength of contraction of the myocardium (heart muscle) depends on the tension before the actual reduction, the more it is stretched, the stronger the subsequent reductions, are subject to the same law, and skeletal muscle (which is why we are waving when committing throwing hand). Before your heart muscle is stretched to varying degrees the volume of blood entering the heart, and the greater the volume, the more intense the contraction, Testosterone Propionate order. The intensity reduction does not increase indefinitely, it is maximal when the muscle is stretched by 35%, even more hyperextension leading to a gradual weakening of contraction.
The second method for enhancing the activity of the heart works when the pressure in its cavity (the volume of the cavity of the heart is not changed) Testosterone Propionate.
Physical activity, depending on the type of exercise has a different effect on the muscles, so we are apparently easy to distinguish from a cyclist or a bodybuilder representative of martial arts. The loads share a fundamental, depending on the processes taking place in the muscle. The physiology is customary to distinguish two types of muscle contractions: static and dynamic. Static load change accompanied tone (voltage) without changing their length (e.g., retention of gravity in one position). It should be noted that the separation of the above types is very conditional. Each physical exercise combines both types, but usually prevails a given type (to varying degrees). In the literature, so you can find such phrases as: exercise, mainly the type of dynamic or mainly static type. In the future, – for the sake of simplicity we shall call the load (exercises) static or dynamic. Buy Testosterone Propionate online.
With dynamic load changes muscle length without a significant change in its stress (flexion and extension of the limbs). This division is essentially loads because Systematic studies in some sport (ie the prevalence of dynamic or static loads) lead to different effects, different effects on the cardiovascular system and determine the prognosis of these different influences. Separation of loads into two types, to a certain extent arbitrary, each sport is a combination of both. Perhaps the predominance of one type or another in some kind of sport.
It is believed that weightlifting – a representative of more than static loads, and athletics (running) – dynamic, it is also believed that the dynamic loads contribute to the development of endurance, and static – forces. The changes in the heart occur gradually, with the systematic exercise, only in this case, the possible development of the heart and blood vessels to adapt to the load and increase functionality, Testosterone Propionate. If sports do not have the systems and are accompanied by extremely high loads, the adaptation does not happen, these are the lessons are harmful to health (sometimes irreparable).
What happens under dynamic loads? As already mentioned, there is a permanent reduction and an increase in the length of muscles. This causes a periodic pressure on the walls of blood vessels, because of which increased blood flow in muscles. It promotes blood flow and expand blood vessels (arteries), observed under these loads. The movement of blood through the veins is improved – squeezing of the outside provides increased pressure in them, and the movement of blood in one direction (in the direction of low pressure). Buy Testosterone Propionate. Unidirectional venous blood flow is possible due to the presence of valves in the veins. These changes provide increased blood flow to the heart and the expansion of its cameras.
Due to the above-mentioned phenomena under dynamic loads experienced higher upper (systolic) and a decrease in the lower (diastolic) blood pressure. Under these conditions the heart to pump blood easier arteries as total vascular resistance is reduced Testosterone Propionate for sale.
