Hypoxia - harm or benefit ?
resistance to lack of oxygen - one of the adaptation factors - determined by genetic and phenotypic characteristics (hereditary and acquired in the course of life).
researchers found that short-term hypoxic exposure within a certain range can increase the body's resistance to the effects of stress, revitalize the vital body functions.
known that mountain residents are centenarians groups and the midlands and highlands differs reduced oxygen content in the air.Therefore, periodic visits of people living in the plains, the mountains contribute to improving efficiency, increasing life expectancy, the preservation of vigorous activity into old age.
in moderate hypoxic conditions improves the body's resistance to a variety of pathogenic factors, increases resistance to stress.
When hypoxia excited brain cells, activates respiration, increases the number of red blood cells and oxygen in the blood, improves blood circulation minute volume.
However, trips to the mountains require significant expenditures, a
study was to determine that the greatest effect is given short-term hypoxic stress.So programs have been "staged" and "Interval" rise in the pressure chamber.
When the "step" the rise after reaching a certain height is rest, t. E. A stay at this altitude for 5-15 minutes, and then climb to the next height.
If "Interval" is an alternation rise to a certain height and descent to a lower, then rise again.Adjustable and stay at each height.
ups and downs during the same session produced a good training effect and significantly affect the increase in hypoxic stability.
When stress adrenaline is released into the blood, causing blood vessels dilate the heart, brain and lungs, but there is a narrowing vessels in the skin (pale man), increased heart rate and increased blood pressure.
blood pressure increases the heart's ability to absorb oxygen.However, not enough trained people who are prone to over-reactivity with negative emotions, such a protective measure can be dangerous and even cause heart failure up to a myocardial infarction.
When excessive reaction to stress, a large amount of the hormone cortisol, reduced ability to quickly assimilate the newly formed sugar, and even may cause temporary diabetes.It is known, for example, that on the stock exchange in the fall in share prices, some people sometimes have "diabetes speculators."
Consequently, excessively high reactivity and low stability under hypoxic stress is the cause of serious shifts in the body.
All this became the basis for in-depth study of human reactions to hypoxia and hypercapnia (elevated levels of carbon dioxide - C02 -in arterial blood).
known physiologists VA Ilyukhin and IB Zabolotskys found that various physiological systems of the body in different ways exhibit hypoxic resistance, which is a characteristic of the adaptive capabilities.
difference adaptation possibilities observed in individuals with different abilities to quickly mobilize their neuro-muscular system to relax.It is set in their studies, conducted over the years, Yu Vysochin.
was installed and another interesting fact: people with a low rate of any relaxation of the muscles of the least resistant to hypoxia.
scientists have identified three types of people:
• relaxants - the rapidly arbitrary relaxation of muscles, the rapid incorporation of its "brake", reducing excessive stimulation (when hypoxic, heat, emotional, extreme environmental influences and physical activity);
• gipertrafiki - have powerful muscular system, but unable to its rapid relaxation;
• mixed (transitional) type - having the average.
Therefore, hypoxic stability and ability to fast relaxation interrelated.
Studies YV Vysocina shown that hypoxic resistance requires special attention and trainers, and doctors, and people suffering from a number of diseases.Increased hypoxic stability and speed of any relaxation of the muscles help to increase the adaptive capacity of the organism.
Muscle man called the "second heart", and indeed it is, because, as shown in his research a famous scientist RP daffodils, voluntary muscles and the myocardium in many diseases act as a safety net.
first acts to protect the neuro-muscular system, with disease metabolism in the muscles are activated at the beginning of the disease (fever) and the end (temperature decreases).
YV Vysochin proved that there is a brake relaxation functional system of protection (TRFSZ), which plays an essential role in ensuring the adaptation processes, normalization of the balance of the nervous processes of the body.
In other words, when the TRFSZ protective function is performed by normalizing the balance of the nervous processes, and improve the speed of any relaxation of muscles.
Increased hypoxic stability interconnected with these processes and more pronounced in relaxants.
People hypertrophic type TRFSZ low activity, increased the amount of muscle mass, increased excitability, low efficiency of the heart.In addition, it was found that such people have low stressors and hypoxic resistance, a large possibility of injuries and diseases.
scientist believes that the increased resistance can be achieved by deliberate action on the formation of a rational type - relaxant.
Increased hypoxic sustainability and arbitrary rate of muscle relaxation allows the person to increase the opportunities for their protection.
likelihood of surge of the musculoskeletal system at relaxants significantly less compared to gipertrofikami.
Relaxation opportunities increase when:
• hypoxic training with a series of short breath (1/2 of the possible maximum delay);
• exits use in the midlands (altitude of 1500-2500 meters above sea level);
• Use barokamernoy training (with a height difference of 1500 to 4000 m);
• Use-heat (sauna, steam bath: a short stay for 8-10 minutes, and breaks in the cool pool temperature);
• Use meditation or autogenous;
• special relaxation exercises.
People with low resistance of hypoxic require special attention during childbirth and operations.
Studies have shown that people with low resistance to characterized by hypoxia and low resistance to physiological stress.
known that adverse effects on human health and the inherent physical and emotional stress.For example, the noise itself is not associated with any risk to humans, can cause not only a state of anxiety, and digestive disorders by inhibiting the activity of the stomach and causing neuroses.
Stress by prolonged exposure may become chronic.
Signs of emotional chronic stress include:
• mood changes;
• increased anxiety;
• fatigue and distraction.
Behavioral manifestations of chronic stress can be expressed:
• Sleep disturbances;
• loss of appetite, and sometimes overeating;
• reducing health and other negative moments.
from hypoxic levels of stability and sustainability depends to some stress.Thus, knowing their hypoxic resistance can take timely measures for its improvement.There are tests, which you can define it yourself.
