The doctrine of human health. Components of human health.

Human life depends on the health status of the organism and the extent of the use of his psycho-physiological potential.

Health – normal psychosomatic condition of a person, reflecting his complete physical, mental and social well-being and ensure their implementation of employment, social and biological functions.

The most widespread currently got a functional approach when considering health. Its peculiarity lies in the individual’s ability to exercise its inherent biological and social functions, in particular, to perform socially useful labour, productive activity. Their loss is the most common and the most important for a person, family, society, the social impact of human diseases.

The origin of the disease has two sources condition of the human organism and external causes, acting on it. Therefore, to prevent diseases there are two ways: or the removal of external causes, or rehabilitation, strengthening the body so that he was able to neutralize these external causes.

The second method is more effective. He is to wherever possible avoid occasions that lead to disease, and at the same time temper your body, teach him to adapt to external influences, to reduce the sensitivity to adverse factors. Therefore, the ability to adapt is one of the most important criteria of health.

The definition of the functional state of the cardiovascular system include heart rate and arterial pressure. General principles of moderate physical activity on the cardiovascular system.

Heart rate is one of the most basic and most widely available indicators reflecting the state of the cardiovascular system. This applies especially to the pulse during the execution of physical activity. In practice, the heart rate reflects the amount of work that needs to perform a heart to meet the body’s need for oxygen. To better understand, compare heart rate at rest and during exercise.

The average heart rate at rest in humans is 60 to 80 beats per minute. During the execution of a physical exercise heart rate will be a direct measure of the intensity of the work. When You begin to exercise, the heart rate increases rapidly in proportion to the intensity of the exercise. To control the work to be performed, typically use pulse indicators are taken as a percentage of Your maximum value.

Blood pressure depends on many factors: time of day, psychological state of the person (under stress pressure increases), acceptance of different stimulant drugs or medication. Persistent increase in blood pressure above 140/90 mmHg.PT. or persistent lowering of blood pressure below 90/50 can be symptoms of various diseases.

The features of the process of breath during physical exertion. Exercise, actively influencing the development of the systems of respiration, circulation and metabolism.

During exercise oxygen consumption and carbon dioxide (O2 and CO2) increase, on average, 15 to 20 times. However, increasing ventilation and tissues of the body receive the necessary amount of O2, and from the body’s output of CO2.

Everyone has individual indicators of external respiration. Normal respiratory rate varies from 16 to 25 per minute, and tidal volume from 2.5 to 0.5 l by muscle load in different capacities pulmonary ventilation, as a rule, proportional to the intensity of work performed and consumption of O2 by the tissues of the body. Untrained persons at maximum muscular work respiratory minute volume not exceeding 80L*min, and can be trained 120-150L*min and above. Short-term arbitrary increase ventilation may be 150-200 liters*min.

At the beginning of muscular work ventilation increases rapidly, however, in the initial period of operation does not occur any significant changes in pH and gas composition of arterial and mixed venous blood.

The level of ventilation in the first few seconds of muscle activity is regulated by signals coming to the respiratory centre of the hypothalamus, cerebellum and motor areas of the cerebral cortex. At the same time the activity of neurons of the respiratory center increases the irritation proprioception working muscles. Pretty quickly the initial abrupt increase in ventilation followed her slow rise to a sufficiently stable state, or the so-called plateau. The state of the “plateau” occurs on average after 30 sec after starting work or changing the intensity of the already performed work. In accordance with the energy optimization of the respiratory cycle, the increase in ventilation during exercise is due to the different ratios of the frequency and depth of breathing. Heavy physical work on the ventilation level will be influenced by the increase in body temperature, catecholamine concentration, arterial hypoxia, and individually limiting factors biomechanics of breathing.

Should as much as possible to breathe through the nose, and switching to mouth breathing with increasing loads automatically. In poor health this transition is governed by the condition of the circulatory system, which determine the physical working capacity of the person. Failure of the circulatory system can be improved with proper breathing.

To cyclic sports (movement) is running, walking, swimming, rowing, Cycling, cross country skiing, skating and many others. They all have several things in common both in terms of movements, and in terms of energy consumption. Cyclic sports, usually include in a Wellness program for the prevention of several diseases of the cardiovascular, respiratory systems, as well as therapeutic purposes.

To achieve the best least stressful by choosing not traditional physical gymnastic exercises, and exercises that require continuous work large groups of muscles, for example, skiing, cross-country running, Jogging, swimming, walking over rough terrain and others. The smaller muscle groups are involved in the work, the lower training effect.

The common cyclical movements is as follows. All phases of movements that exist in one cycle are present and the other, and in the same sequence. Cycles from each other cannot be separated.

A significant portion of the cyclic movement is a natural locomotion (movement) or are based on them. The main variables in cyclic movements are power and dyatelnosti (duration) of work performed. Power is determined by the frequency of motor cycles, amplitude, and force of movements.

The classification of cyclic exercise on physiological stress may be taken as the magnitude and direction of the energy shifts, as measured by accumulation of metabolic products (e.g. lactic acid) in the blood and muscles, and changes in key life-support systems and regulation (e.g., cardiovascular, respiratory, Central and peripheral systems).

Depending on the peculiarities of energy ensure the physical exercises are divided into aerobic and anaerobic.
