What happens in the human body while running?

In the process of running training, the number of heart contractions decreases, the heart becomes more powerful and works more economically.

Due to the fact that with a long rhythmic run, the pulse becomes 120-130 beats per minute (by the way, we previously wrote about the pulse zones when running), and the peripheral blood vessels expand, their resistance decreases, which leads to a decrease in blood pressure. Frequent breathing, along with increased sweating, protect the body from overheating during a period of pronounced physical activity.

Physical activity is one of the key aspects of a healthy lifestyle. They have an analgesic effect and continue to work for 0.5-1 hours after running. Long unhurried running is ideal for overcoming cyclic anti-gravity load. Most of the blood vessels in the body are located vertically, and the capillary blood flow at rest per 1 sq. In addition, the joints of the human body receive a payload while running. mm of muscle cross section is open at approximately 30-80 capillaries.
During running, when a person constantly overcomes Earth’s gravity, jumping and falling in an upright position, blood flow in the vessels also “sways”, enters into resonance with running. It trains the vascular system and prevents many heart diseases
During exercise, blood begins to move through vessels with high intensity. Optimal physical activity can be achieved by walking, running, practicing outdoor sports, dancing, and performing gymnastic exercises.

The processes taking place in the human body during the period of physical activity are accompanied by the intensification of metabolic processes (metabolism), primarily in muscle cells, and, consequently, an increase in their need for additional oxygen and nutrients.
Already with moderate, and even more so with pronounced physical activity, intensification of the heart (increase in the frequency and strength of contractions) and respiratory system (increase in the frequency of respiration with increased gas exchange and saturation, lungs with oxygen) occurs. The flow of hormones increases and is now able to reach the most distant cells and establish their work, which becomes more harmonious, harmonious and balanced.

As a rule, after a long run (30 minutes or more), a sensation arises in which special hormones are produced – endorphins, which cause a natural feeling of bliss. It makes a person not only physically more attractive, but also significantly improves his health, positively affects life expectancy, especially of its active part.

During running, there is a soft “shake” of all internal organs (liver, stomach, pancreas, kidneys, etc.) – this is an ideal stimulator of their work. During running, almost all parts of the ligamentous and muscular apparatus are involved. Through the walls of blood vessels, a lot of waste substances enter it, which are removed through sweat. Running also slows down the aging process, because it activates intracellular biosynthesis, normalizes the activity of the central nervous system, activates and regulates the activity of the endocrine glands, strengthens the immune system – increases the body’s defenses, infects the body with energy and helps to fight against excessive and uncontrolled eating.
It is especially effective for hypertension and hypotension, vegetative-vascular dystonia, angina pectoris, coronary heart disease, rheumatism, heart mitral valve insufficiency, osteochondrosis, and gastric ulcer.

Motivation for running
The following main motivations of middle-aged people to do jogging are distinguished:

health promotion and disease prevention;
increased performance;
pleasure from the running process itself;
the desire to improve their results in running (sports motivation);
following the fashion for running (aesthetic motivation);
desire for communication;
desire to know your body, your abilities;
motivation of creativity, motivation of raising and strengthening the family;
“Family” run;
random motivation.
The most powerful incentive for training is just pleasure, a huge sense of joy that running brings. At the same time, early “sleeping” capillaries gradually open. For example, while running, food debris located in the intestine is mechanically irritated. In most cases, those people who, as a result of improper training, were not able to experience these sensations, stop training.

Low physical activity (lack of exercise) can cause the development of muscle atrophy. With a slow, long run, the metabolic processes of the body normalize, and the cholesterol content in the blood also decreases. High – accompanied by an increase in muscle mass (hypertrophy), strengthening of skeleton bones, increased joint mobility. Running increases blood circulation, oxygenates all organs and tissues. Such microcirculation activates the activity of internal secretion organs.
