If you consider the concept of “steroids” scale, then it can be any means that can enhance the anabolic background in the body. To these can be considered various medicinal synthetic or herbal preparations, sportspit, etc. But physiological stimulators of anabolism are of particular interest, since they do not have side effects.

For sure about some of them you know, here is their list:

  • Effects on the body of high and low temperatures.
  • Run.
  • Short-term fasting, the duration of which does not exceed a day.
  • Hypoxic breathing training.
  • Strictly dosed out effects.

Perhaps, only running out of all these receptions causes the most controversial opinions among bodybuilders. Someone is sure that running only destroys the muscle mass, but there are many supporters of using cross-country sessions in training programs. However, even supporters of the race can not find a common ground in the matter of its intensity in terms of maximum efficiency for the bodybuilder.

If you look at the history of sports, it is also impossible to find an unambiguous answer. There are many well-known siloviki athletes who classify themselves as supporters of the race, and its opponents.

It is believed that with properly organized training and nutrition, a bodybuilder can collect on average about three and a half kilos of weight. However, there is evidence that even without the use of sports nutrition, athletes managed to gain about 20 kilos for 12 months. However, for the sake of justice we note that all these athletes trained after a long pause.

However, there is one more fact that unites them all – earlier they were engaged in athletics. Let’s now consider running, as a natural steroid in bodybuilding.

The influence of running on the body

Running is the simplest and most effective physical exercise, which allows you to use almost all parts of the ligament and muscle apparatus. In addition, the joints of the human body receive a payload during running. Running increases blood circulation, oxygenates all organs and tissues. He trains the vascular system and prevents many heart diseases.

Running classes help to cleanse the body of harmful toxins and toxins. During the exercises, blood begins to move through the vessels with high intensity. Through the walls of the vessels it receives a lot of waste substances, which are discharged through sweat. With a slow long run, the metabolic processes of the body are normalized, and the content of cholesterol in the blood decreases.

Running helps to get rid of excess calories. It’s not for nothing that running is considered one of the most effective ways to lose weight and is included in most programs to combat overweight.

According to scientific research, running by running contributes to the development of endorphins – hormones that cause a person a sense of joy, happiness and optimism. In addition, running increases the endurance of a person, making it more workable.

Influence of running on the physiology and biochemistry of the organism


You should be aware that energy is often the main limiting factor in the growth of muscle mass. It is also known that energy is produced by mitochondria. These organelles practically do not participate in the synthesis of proteins, but they produce energy very actively.

Muscle fibers will not begin to grow until the hypertrophy of mitochondria is reached. It is the increase in the size and quantity of these organelles that is the first result of strength training. This contributes to an increase in the body’s energy capabilities and only then the growth of muscle tissue cells is activated. Thus, the impact on muscle strength training can be divided into several stages:

  • Training leads to the depletion of energy.
  • Deficiency of energy forces the body to synthesize neurotransmitters, which in turn trigger the process of protein synthesis.
  • Increasing the speed of protein production causes the growth of mitochondria and increases their number.
  • After increasing the energy potential of the body, the mechanisms of growth of muscle fibers are triggered.

It is the hypertrophy of the mitochondria that becomes the harbinger of muscular growth. It is important to note here that it is running that is the best way to accelerate mitochondrial hypertrophy. If you look at the lean bodies of runners, you can understand that their body is able to make the most efficient use of all available energy carriers, including fats. At the same time, their muscles contain a large number of mitochondria.

If we now imagine that the runner begins to engage in bodybuilding, then it becomes obvious that he has the most powerful energy potential for muscle growth. He no longer requires hypertrophy of the mitochondria, since these organelles are already present in sufficient quantities in the tissues.

Endocrine system

Under the influence of strength training, the body begins to actively produce catabolic hormones. As a result, all fats are split up to glycerol and fatty acids, protein compounds to amines, and glycogen to glucose. This is done so that the body does not experience energy deficiency.

Also produced and anabolic hormones that prevent strong splitting of protein compounds. However, glycogen and fats continue to be split, and glycerin along with fatty acids begins to participate in energy exchange.

After the training the situation changes to the opposite and the production of catabolics decreases, and the concentration of anabolic hormones remains high. If at this time the concentration of somatotropin is high, then insulin accelerates the synthesis of protein runningcompounds. Otherwise, the formation of fatty tissues is accelerated.

The maximum changes in the hormonal background are observed during the running session, as a serious energy deficit is created. Also note that under the influence of physical activity, powerful changes in the work of the hormonal system are observed only at the beginning of the session. Then the body increases not the amount of hormones, but increases the release of intracellular hormonal mediators.

Under the influence of any physical activity, the adrenal glands are gradually hypertrophied, which leads to a more powerful synthesis of catabolic hormones. But for runners this body is not hypertrophied to the same degree as the siloviki. Elimination of the energy deficit in their body is due to an increase in the sensitivity of cellular structures to adrenaline and glucocorticoid hormones. For this reason, the catabolic background of runners is not so high and in the after-load period the anabolic background rises faster.

Nervous system

Nerve signals spread very quickly only through the nervous processes. Their transmission between cells can be quite long, because for this special substances are used – neurotransmitters, and even more accurately catecholamines. With any physical activity, the nerve cells responsible for the synthesis of catecholamines are activated. But in this respect, the run exceeds any other kind of load.

With regular jogging, the nervous system is hypertrophied, and the transfer of information between cells is much faster. Thus, based on all of the above, we can state the fact, then running does not promote the recruitment or destruction of muscle mass. It only creates the prerequisites for increasing the effectiveness of strength training. Today, more and more athletes-siloviki begin to use the run in their training programs.
