Adaptation to stress situations and physical loads

 

The book is devoted to the mechanism of adaptation of the organism to physical stress and stress situations, the use of this adaptation and its chemical “mediators” for the prevention and treatment of noncommunicable diseases, which represent an open challenge to modern medicine. Justified new view of stress-limiting systems of the organism and it is shown that

with the help of metabolites of these systems and their synthetic analogues can be successfully alerted diverse stress damage the body — from ulcerative lesions of the gastric mucosa to cardiac arrhythmias and ventricular fibrillation in myocardial infarction.

The main factors that modify the power of exercise in rehabilitative treatment

 

Load in exercise — is, first of all, the magnitude of the impact on the human body and the degree of overcoming engaged in objective and subjective difficulties. The effectiveness of physical activity is directly proportional to its volume and intensity.

In physical therapy uses physical exercises, specially selected and methodically reasoned, with the ultimate goal — the recovery of the

patient. It is necessary to consider the clinical picture of the disease, anatomical and physiological characteristics of the organism, presence of comorbidities, and the degree of physical fitness of the patient.

The volume, the nature of the movements, the sequence of application of physical exercises a strong influence on the therapeutic effect. Methodically Continue reading

The effect of exercise on human physiology

 

Intense exercise significantly alter the functioning of the vital systems of the human body.

In the quiescent state of a man aged 16-45 years blood pressure is characterized by minimal pressure 60-85 mm Hg. article maximum pressure 110-125 mm Hg. article the Number of contractions of the heart lies in the range 60-80 beats per minute. When this is run the whole blood volume – 3-5 liters (6-7% of body weight).

During physical exercise increases the cardiovascular system, which significantly increases the bloodstream. Due to the increase of stroke volume and increased frequency of contractions, cardiac output (in medical terminology) is increased by 5-10 times, that is, with 3-5 20-40 liters. As the load increased contractions of the heart can reach 180 to 240 beats per minute. However, it is effective only to the level 150-190 BPM. Hard work increases blood pressure, the minimum Continue reading
