Physical exercise.

  1. PHYSICAL LOADING TEST
    Used to assess the adequacy of the processes of regulation of hemodynamics during exercise, provocation of the occurrence of arrhythmias and conduction. The level of load imposed is different in healthy individuals and in patients with cardiovascular disease (patients are allowed to achieve only submaximal load). The method of conducting the sample: The subject is proposed to fulfill the dosed load.
  2. Samples with dosed physical load
    An electrocardiogram, recorded at rest, outside of a painful attack, in a patient without a MI in history, may be normal. During the test with the dosed physical load, the patient performs an increasing load on the treadmill or VEM, and the HR and ECG are constantly recorded, and the blood pressure is monitored at regular intervals (1-3 min). Treadmill test compared with VEM has both advantages and
  3. Ventricular tachycardia during exercise
    Ventricular tachycardia, which develops during exercise (Fig. 8.4), is observed much less frequently than ectopia of lower degrees. During a large series of stress tests on treadmill, in 5,730 patients successively injected, 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 for physical exertion
    INDICATIONS FOR PHYSICAL TRAINING? Risk factors: low physical activity, arterial hypertension (mild and labile form), hypercholesterolemia, overweight; ? Vegetovascular dystonia, hypotension, dyshormonal myocardial dystrophy; ? Angina I-III functional class; ? Type II diabetes mellitus (insulin-independent) in the compensation stage;
  5. SPECIMEN PHYSICAL LOADING TESTS
    Exercise testing is a common, as well as affordable method of diagnosis and examination of patients with cardiovascular diseases. As early as 1929, Master and Oppenheimer developed a standardized load protocol for assessing the functional status of IHD patients. Over the next 30 years, we studied the mechanisms of ST segment displacement, the influence of the position of electrodes on ECG changes,
  6. Factors Affecting Exercise Test Results
    Digoxin. Digoxin causes load-induced depression of the ST segment in 25-40% of practically healthy individuals. With age, the pathological response prevails. B-adrenoreceptor blockers. If possible, it is recommended that the blockers of B-adrenergic receptors (and other anti-ischemic drugs) be canceled 4-5 times longer than the half-life of the drug (usually about 48 hours) before
  7. Bronchospasm caused by exercise in patients with bronchial asthma
    In many children with asthma, attacks are provoked by physical exertion. Post-loading bronchospasm is characteristic of 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 does not occur. The development of bronchial hyperreactivity, bronchospasm, the appearance

  9. Load concept
    Not even any systematic physical activity can be considered as training, since an increase in the functional capabilities of the organism, that is, training effects, occur only under the 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 performed external work and
  10. The fight against smoking, alcoholism at school age. Physiological and hygienic fundamentals of physical education: the effect of exercise on the functional systems of the body
    FUs do not influence in isolation on 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. Especially distinct are changes in the muscular system. They are expressed in increasing the volume of muscles, changing the physicochemical properties of tissues, enhancing metabolic processes, improving functional
  11. Basics of load physiology
    During the early phases of the load in an upright position, an increase in cardiac output occurs, which is realized through an increase in heart rate and the Frank-Starling mechanism. In the later phases of the load, the main mechanism for the growth of cardiac output is a further increase in heart rate. In healthy people for a few minutes after the start of the load a stable state is reached (steadystate);
  12. Physical development of the population, signs of study, assessment of physical development
    Physical state is the degree of a person's willingness to perform muscular and labor loads of a different nature in a given specific period of time. Physical development is a complex of physical, morphological and functional properties of an organism, which determine the mass density, body shape, structural and mechanical qualities and are expressed by the stock of its physical forces. Factors affecting
  13. Hygienic standardization of academic, extra-curricular and extracurricular workload
    For the prevention of a sharp drop in the performance of students during the school day and the school week, the schedule of classes in school is of great importance for the prevention of early fatigue and overwork. In drawing up the lesson schedule, first of all, it is necessary to take into account the duration of the school day and the school week corresponding to the age possibilities of children and adolescents.

  15. Hygienic requirements for daily, weekly, study load
    Protecting the health of school-age children and ensuring the optimal functional state of their body without overstressing the nervous system and overwork is primarily due to the proper organization of the educational process and adherence to educational standards. New educational institutions with expanded and advanced education content (lyceums, gymnasiums, private schools and
  16. Physical development. Methods for determining and assessing the physical development of children
    Physical development is understood as a combination of morphological and functional signs of the body: height, weight, chest circumference, 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, sustainability depends on the level of physical development.
  17. How to measure physical development and use physical development maps
    Physical development is an increase in mass and body dimensions, which includes the components of body mass (weight component) and length or height (linear component). In assessing physical development, accurate measurement of both components is essential. To ensure accurate and reliable measurements, the unification of the methodology and equipment calibration is extremely important. By
  18. Overload hypoxia ("load hypoxia")
    Occurs during intense activity of an organ or tissue, when the functional reserves of oxygen transport and oxygen utilization systems in the absence of pathological changes in them are insufficient to provide sharply increased oxygen demand (excessive muscular work, heart overload). For overload hypoxia is characterized by the formation of "oxygen debt" with increasing
