Physical exercise.

  1. SAMPLE WITH PHYSICAL LOAD
    It is used to assess the adequacy of hemodynamic regulation during exercise, provocation of rhythm disturbances and conduction. The level of the load is different in healthy individuals and in patients with SSS (only submaximal load is allowed for patients). Procedure of the sample: The subject is asked to perform a metered load
  2. Samples with dosed physical activity
    ECG, recorded at rest, outside the pain, in a patient without a history of MI, may be normal. During the test with the dosed physical load, the patient performs an increasing load on the treadmill or BEM, constantly recording the heart rate and ECG, and at regular intervals (1-3 min) monitor BP. Treadmill test in comparison with BEM has both advantages and
  3. Ventricular tachycardia with exercise
    Ventricular tachycardia, which develops under physical exertion (Figure 8.4), is observed much less frequently than ectopy of lower degrees. In a large series of stress tests on treadmill, in 5730 consecutive patients, ventricular tachycardia occurred in 47 of them (0.8%) [17]. In another series, including 713 consecutive patients, ventricular tachycardia with
  4. Individual indications and contraindications to physical activity
    INDICATIONS FOR PHYSICAL TRAINING? Risk factors: low physical activity, arterial hypertension (mild and labile form), hypercholesterolemia, excessive body weight; ? Vegetosovascular dystonia, hypotension, dyshormonal myocardial dystrophy; ? Angina of stress I-III functional class; ? Diabetes mellitus type II (insulin-independent) in the stage of compensation;
  5. SAMPLES WITH DOSED PHYSICAL LOAD
    Load tests are a common, as well as an accessible method for diagnosing and examining patients with cardiovascular diseases. As early as 1929, Master and Oppenheimer developed a standardized load protocol for assessing the functional state of patients with IHD. Over the next 30 years, the mechanisms of the ST segment displacement, the influence of the electrodes position on ECG changes,
  6. Factors affecting the results of tests with physical activity
    Digoxin. Digoxin causes a load-induced depression of the ST segment in 25-40% of practically healthy individuals. With age, the pathological response prevails. Blockers of B-adrenergic receptors. If possible, it is recommended that the blockers of B-adrenergic receptors (and other anti-ischemic drugs) be canceled within 4-5 times the half-life of the drug (usually about 48 hours), before loading with the goal of
  7. Bronchospasm, caused by physical exertion, in patients with bronchial asthma
    Many children suffering from bronchial asthma, attacks are provoked by physical exertion. Poslenagruzochny bronchospasm is typical for the vast majority of children with bronchial asthma (60-90%). At the same time, "bronchial asthma of physical stress" as an independent form of the disease in children is not found. Development of bronchial hyperreactivity, bronchospasm, appearance

  9. The concept of load
    Not even any systematic physical activity can be considered as a training, since the enhancement of the body's functional capabilities, that is, training effects, arise only on condition that the training loads reach or exceed a certain threshold value. Speaking about the load, it should be characterized from two points of view: as the value of the external work performed and
  10. Combating smoking, alcoholism at school age. Physiological and hygienic basis of physical education: the effect of physical exercises on the functional systems of the body
    FUs do not affect in isolation any organ or system, but on the whole organism. However, the improvement of the functions of its various systems does not occur to the same extent. Particularly distinct are the changes in the muscular system. They are expressed in increasing the volume of muscles, changing the physico-chemical properties of tissues, enhancing metabolic processes, improving functional
  11. Fundamentals of the physiology of the load
    During the early phases of the load in the vertical position, there is an increase in cardiac output, which is realized through increased heart rate and the Frank-Starling mechanism. In later phases of the load, the main mechanism of cardiac output growth is a further increase in heart rate. In healthy people, within a few minutes after the onset of exercise, a stable state is achieved (steadystate);
  12. Physical development of the population, signs of study, assessment of physical development
    Physical condition is the degree of a person's readiness to perform muscular and labor loads of a different nature in this particular period of time. Physical development is a complex of physical, morphological and functional properties of the organism that determine the mass density, body shape, structural and mechanical qualities and are expressed by the reserve of its physical forces. Factors affecting
  13. Hygienic rationing of educational, extra-curricular and extra-school load
    To prevent a sharp drop in the performance of students during the school day and the school week, to prevent early fatigue and fatigue is important school schedule. When drawing up the timetable for lessons, it is first of all necessary to take into account the length of the school day and the school week corresponding to the age opportunities of children and adolescents.

    Optimization of educational
  15. Hygienic requirements for the regime of the day, week, training load
    The protection of the health of school children and ensuring the optimal functional state of their body without the phenomena of overstrain of the nervous system and fatigue are primarily due to the correct organization of the educational process and the observance of the norms of educational activity. New educational institutions with an expanded and in-depth content of education (lyceums, gymnasiums, private schools and
  16. Physical development. Methods for determining and evaluating the physical development of children
    Physical development is understood as the set of morphological and functional features of the body: height, weight, circumference of the chest, lung capacity, muscle strength of hands, etc. Physical development is directly related to the state of the cardiovascular, respiratory, digestive, musculoskeletal and other systems . In turn, the level of physical development depends on stability
  17. How to measure physical development and use physical development maps
    Physical development is an increase in the mass and dimensions of the body, which includes the constituent mass of the body (weight component) and length or height (linear component). In evaluating physical development, the precise measurement of both components is of paramount importance. To ensure accurate and reliable measurements, unification of the technique and calibration of equipment is extremely important. By
  18. Overload hypoxia ("hypoxia load")
    It occurs when the activity of the organ or tissue is intense, when the functional reserves of the transport and utilization systems of oxygen, in the absence of pathological changes in them, are insufficient to provide sharply increased oxygen demand (excessive muscular work, cardiac overload). For overloading hypoxia, the formation of an "oxygen debt" is characteristic when increasing
