Hypertensive Hell reaction on physical exertion. Types of cardiovascular reactions - vascular system for physical exertion

BMI \u003d body weight (kg) / height2 (m)

The body mass index (BMI) is used to assess the mass in relation to growth and provides an acceptable assessment of the entire body fat in studies related to certain groups of the population. In addition, BMI correlates both with morbidity and mortality, thus, it provides direct indicators of the state of health and the risk of morbidity.

The method does not provide information on the distribution of fat in different parts of the body, it is difficult to explain to the client and it is difficult to plan the actual loss of body weight due to changes in BMI. In addition, it was shown, BMI overestimates the fat weight of the body in muscular faces (for example, many athletes) and underestimates people with muscle loss (for example, in elderly people).
Surplusing mass is determined when BMI is 25 - 29 kg / m2, and obesity - when BMI is greater than 30 kg / m2. People with CMT are more than 20 kg / m2, mortality in many states of health increases with increasing body weight.
World Health Organization (WHO), for men and women recommended by BMI, 20 - 25 kg / m2

Vegetative index (Kerdo Index)

Vi \u003d (1 - ADD / CSS) x 100
It is considered to be one of the simplest indicators of the functional state of the autonomic nervous system reflecting the ratio of excitability of its sympathetic and parasympathetic departments (excitation and braking, respectively - SSF). The magnitude of the V in the range from -15 to +15 indicates the equilibiousness of sympathetic and parasympathetic influences. The value of V MORE 15 speaks of the predominance of the tone of the sympathetic department of the vegetative nervous system and indicates a satisfactory adaptation to the workload, the value of obtaining is less minus 15 indicates the predominance of the tone of the parasympathetic unit of the autonomic nervous system, which is a sign of the presence of dynamic mismatch (rozens, fields, 2006; C. - 156).
The trained person of Vi before the classes is usually with a minus sign, or is in the range from - 15 to + 15.
Excessive increase in V typically indicates a human hypertensive reaction to the load - the inconsistency of the proposed load of the training level. Such loads should not be frequent even from well-trained athletes.
The decrease in V also testifies to poor load tolerance. The V values \u200b\u200bbelow - 15 indicate the most unfavorable type of reaction of the autonomic nervous system to the load - hypotonic.

Blood Pressure (AD)

It is measured at rest, so 15 minutes before its definition should not be any activity. If systolic pressure exceeds 126 mm Hg. Art., and diastolic - 86 mm Hg. Art., Measure it again after hyperventilation (five maximum deep and fast breaths of exhalations). If the pressure remains elevated, check the width of the cuff and again after 15 minutes. If it continues to remain elevated, carry out a deeper examination.
Sexual differences on the level of blood pressure do not affect, but after the period of puberty (16 - 18 years), hell in men is somewhat higher than that of women. Daily hesitation AD make up at least 10 - 20 mm RT. Art. And fall during night sleep.
The horizontal position of the body, physical and mental peace refer to the factors that reduce blood pressure. Reception, smoking, physical and mental stress, leads to an increase in blood pressure with high physical exertion, blood pressure can significantly increase. The reaction of the ADD is especially important. In trained athletes, intensive load is accompanied by a decrease in ADD.
Hell in persons with obesity is higher than those with normal or reduced weight (muscle mass). At the athletes living in the cold climate hell at 10 mm Hg. Art. Above, with warm weather, trends are noted to reduce blood pressure.
The pressure asymmetry is noted: the hell on the right shoulder is slightly higher than on the left. In rare cases, the difference reaches 20 and even 40 mm Hg. Art.

Systolic pressure (ADS)

Systolic pressure is considered normal at values \u200b\u200bfrom 90 to 120 mm Hg Art.

• The value is below 90 - hypotension, most often observed in women due to the small absolute mass of muscles and the body in general, as well as low growth. Also may indicate insufficient nutrition (starvation, non-physiological diet).
• Values \u200b\u200bfrom 120 to 130 mm RT ST - moderately increased blood pressure. Moderately increased pressure may be observed in peace in persons with large growth values, body weight and / or muscle mass (especially with a sharp increase in body weight). It may be the reason for the excitation of a person before loading, the "White Kolata" syndrome or caused by a recent welcome.
• 140 and above are a sign of hypertension, but numerous measurements are required during the day to clarify the diagnosis. If the diagnosis is confirmed by the doctor is obliged to recommend reception of drugs normalizing pressure.

Diastole Pressure (ADD)

It is considered normal at values \u200b\u200bfrom 60 to 80 mm RT pillar.

• Values \u200b\u200bfrom 80 to 90 mm RT state indicate a moderately increased EDD.
• ADD 90 mm RT Art and above - a sign of hypertension.

It should be noted that the final conclusion is not done for the better, but for the worst of the indicators. Thus, as 141 at 80 and 130, 91 testify to hypertension.

Pulse pressure (PD)

Determined as the difference between systolic and diastolic pressure. All other things being equal (the same peripheral resistance, blood viscosity, etc.), the pulse pressure changes in parallel with the size of the blood systolic volume (indirect meter of myocardial load). Normally, it is 40 - 70 mm Hg. Art. Pulse pressure can increase as a result of an increase in ADS or a decrease in ADD

Average blood pressure (garden)

Garden \u003d Add + 1/3 (ADS - ADD)
All changes in the average blood pressure are determined by changes in the minute volume (MO) or total peripheral resistance (OPS)
Garden \u003d MO x OPS
Normal garden indicator can be maintained against the background of reducing the OPS due to the compensatory increase in MO.

Five types of reaction of the cardiovascular system (CSS) on physical exertion
(Kupavsky, 1975; Epifanov. 1990; Makarova, 2002)

1. Nimothonic type of reaction of the CSS The physical activity is characterized by:

• adequate intensity and duration of work performed by increasing the heart rate, in the range of 50 - 75% (Epifanov, 1987);
• an adequate increase in pulse blood pressure (the difference between systolic and diastolic blood pressure) by increasing systolic blood pressure (no more than 15-30% (Epifanov, 1987)) and small (within 10 - 35% (Makarova, 2002), 10 - 25 % (Epifanov, 1987)) with a decrease in diastolic blood pressure, an increase in pulse pressure no more than 50 - 70% (Epifanov, 1987).
• quickly (i.e., stacked in the specified recreation intervals) Restoration of heart rate and hell to starting values

The normal type of reaction is the most favorable and reflects the good adaptability of the body to physical exertion.

2. Dystonic type of reaction As a rule, it occurs after loads aimed at the development of endurance, and is characterized by the fact that the diastolic blood pressure is listened to 0 (the phenomenon of the "infinite tone"), systolic blood pressure increases to the values \u200b\u200bof 180-12 mm RT. Art. (Karpman, 1980). The appearance of a similar type of reaction after re-loading after classes is possible.
When the diastolic blood pressure is returned to initial values \u200b\u200bfor 1-3 minutes of recovery, this type of reaction is regarded as an option of the norm; When preserving the phenomenon of "infinite tone" for a longer time - as an unfavorable sign (Carpman, 1980; Makarova, 2002).

3. Hypertensive type of reaction Characterized:

• inadequate load with increasing heart rate;
• inadequate load with an increase in systolic blood pressure to 190 - 200 (up to 220) mm Hg. Art. More than 160 - 180% (Epifanov, Apanesenko, 1990) (at the same time, diastolic pressure is also somewhat rising by more than 10 mm Hg. Art. (Epifanov, Apanasenko, 1990) or does not change, due to a significant hemodynamic impact during physical exertion in some athletes (carpman, 1980));
• slow down restoration of both indicators.

The hypertensive type of reaction indicates a violation of regulatory mechanisms that determine the reduction in the economy of the functioning of the heart. It is observed in chronic CNS overvoltage (neurocirculatory dystonia according to hypertensive type), chronic overvoltage of the cardiovascular system (hypertensive) in pre-and hypertensive.

4. Reaction with stepped increase Maximum blood pressure is characterized by:

• sharp increase in heart rate;
• continuing in the first 2 - 3 minutes of rest with an increase in systolic blood pressure compared with the 1st minute of recovery;

This type of reaction is unfavorable. It reflects the inertia of regulatory systems and is registered, as a rule, after high-speed loads (Makarova, 2002). Experience indicates that the above reaction type is associated with the deterioration of the functional state of the body of the athlete (Karpman, 1980., from 113). The load time (30c) may be insufficient for the work of the cardiovascular system, which lasts a number of indicators lasts 1 - 3 minutes. In some persons, despite the cessation of the load, the deployment of the function of the blood circulation may continue for some time (Carpman, 1980, and there). Thus, a similar type of reaction is most likely to arise after the first sample with the 20th squats, which is performed before classes.

5. Hypotonic type of reaction characterized:

• sharp, inadequate load with increasing heart rate (up to 170 - 190 UD. / Min (Karpman, 1980); more than 100% (Epifanov, Apanesenko, 1990); up to 120 - 150% (Epifanov, 1987));
• the lack of significant changes from the AD (systolic pressure is weakly or not at all increase, and sometimes even decreases, the pulse pressure decreases (Epifanov, Apanesenko, 1990));
• slow recovery heart rate and hell.

The hypotonic type of reaction is the most unfavorable. It reflects a violation (decline) of the contractile function of the heart ("hyposistol syndrome" in the clinic) and is observed in the presence of pathological changes in myocardium (Makarova, 2002). An incident, the increase in minute volume is provided mainly to the increase in heartbeat, while the increase in systolic volume is small (Carpman, 1980).
Pathological reactions to the load with regular physical training can go to physiological (Epifanov, 1987., from 50). With adverse types of reaction that are most often manifested at the beginning of the preparatory period (Carpman, 1980., from 114), additional (clarifying) pressure measurements described (Richard D. H. Bekus, and David K. Raid 1998., C 372 ).

Additional Information.

If high-intensity training activities are planned (especially preparation for competitions), it is necessary that the client passes a complete medical examination (including a dentist).
To verify the state of the cardiovascular system, it is necessary to produce an ECG under load. Possible myocardial pathology reveals an echocardiogram.
Be sure to evaluate the diet (the analysis of everything that was eaten for a week or more) and the time regime is the possibility of organizing adequate recovery.
It is strictly forbidden to prescribe medicines to the client (especially hormonal) is the duty of the doctor.

The direction of the client on ECCG and ECG under load to exclude cardiac pathology is recommended under the following circumstances:

• Positive answers to questions about symptoms of diseases of the CSS
• Slowdown recovery of pulse and / or breathing during informational classes
• High rates of heart rate and blood pressure with minor loads
• Adverse Type of Physical Reaction Type
• Cancer diseases in history (previously transferred)

Before receiving the survey results:

• Pulse when walking no higher than 60% of the maximum (220 - age). If you can enter the additional aerobic load in free days, gradually increasing its duration up to 40 to 60 minutes.
• The strength of the class is 30-40 minutes, follow the technique of performing exercises, use the pace 3: 0.5: 2: 0, controlling the breathing (not allowing breathing delay). Use the alternation of the exercise for the "top" and "Niza". Do not rush with increasing intensity
• From available control methods before Use blood memories before and after training, heart rate before and after (if there is a pulsometer - then during class). Watch the speed of respiratory recovery, until its normalization, do not start the next approach.

The article prepared Sergey Stroks

The value of the types of reaction is confirmed using modern research methods (Karpman V.L., 1976; Guminer P.N., 1978; Motylyanskaya R.E., 1980; Debo A.G., 1980, etc.). The main drawback of the sample (lack of quantitative performance indicators) can be somewhat compensated for by the quality characteristic of the load performance (monitor the accurate observance of the specified tempo, the knee lifting height when running and others).

Nimotonic reaction (moderate, corresponding to the load conjugate increase in heart rate and maximum blood pressure, a slight decrease in the minimum, increasing the pulse amplitude and rapid recovery) indicates the correct adaptation to the loads, reflecting the good functional state of the subject. With an increase in training, the reaction is erects, recovery is accelerated.

Atypical reactions (hyper-, hypo and dystonic) reflect less effective adaptation to the loads, which is most often with the shortcomings of the functional state.

Hypertensive reaction - Significant (up to 220 mm.rt. and more) increase the maximum blood pressure with a tendency to increase the minimum and considerable increase in pulse (up to 170-180 UD / min or more). All arterial pressure indicators (average, lateral, finite), tone of vessels, peripheral resistance are increased. Such a reaction is more often found in the middle and old age, in the initial stages of hypertension, sometimes with physical overvoltage.

Hypotonic reaction - A minor increase in the maximum blood pressure with a significant increase in pulse (an increase in the minute volume of blood is mainly due to the CSS with a slight increase in systolic volume) and slow-down recovery - is characteristic of the state of overwork and asthenization due to the suffering disease or other reasons.

Dystonic reaction - a sharp decrease in diastolic pressure, up to listening to the so-called infinite tone (mercury in the pressure gauge on the zero level), with a significant increase in systolic blood pressure and the participation in heart rate. Since in the first seconds after the load of the maximum intensity, the infinite tone is listened to very often, which depends on normal hemodynamic influences, the diagnostic value of such a reaction can be given only in cases where the infinite tone holds at least 1-2 minutes or appears after moderate power loads. R.E. The Motylanskaya (1980) established the connection of this phenomenon with a hyperkinetic type of blood circulation, one of the causal mechanisms of which may be physical overvoltage. The dystonic reaction may also be observed after diseases, in the aggravated medium conditions, with neurocircular dystonia. As one of the physiological variants of the device, such a reaction is sometimes found in adolescents.

"Step reaction." In the recovery period after the load, the maximum blood pressure continues to rise, reaching the greatest value in 2-3 minutes, which is due to a circulatory control disorder and is determined mainly after the speed of the sample that requires the fastest inclusion of regulatory mechanisms. The appearance of such a reaction in the training process most often indicates overwork or malfunction, but may also be observed with other states related to a decrease in blood circulation function due to the inability to the rapid redistribution of blood during exercise. The persistent response of the athlete, as a rule, reflects the individual features of adaptation to high-speed loads, which often corresponds to the insufficiently high sports results at high-speed exercises.

However, since the secondary lifting of systolic pressure in the first seconds after the load is observed often and disappears the faster, the higher the level of preparedness, the diagnostic value is such a reaction when the step is at least 10-15 mm.rt.st. Determined after 40-60 s after load.

The most important role in diagnostics plays a combined reaction - the simultaneous presence of signs of various atypical reactions during slow recovery, which clearly reflects the poor functional state and disruption of the training.

The value of the types of reaction is confirmed using modern research methods (Karpman V.L., 1976; Gu-generator P.N., 1978; Motylyanskaya R.E., 1980; Debo A.G., 1980, etc.). The main disadvantage of the sample (the absence of quantitative performance indicators) can be somewhat compensated for by the quality characteristic of the load performance (monitor the accurate observance of the specified tempo, the height of the knees when running, etc.)

The sample is especially valuable at dynamic observations. The emergence of atypical reactions in a runtime, who had previously, the normalone reaction, or slowing down the recovery indicates a deterioration in the functional state. Increased training is manifested by a further improvement in the quality of the reaction and the acceleration of recovery.

Installed back in 1951. Letunov and R.E. Motyanskaya in relation to the combined functional sample, the types of reaction can be used with any physical exertion, since additional criteria are given to the reaction assessment.

From samples (tests), allowing accurately to take into account and quantify the work performed, in the practice of sports medicine and therapeutic physical education, uses mainly climbing the step (step test), cycle ergometric samples and samples on the treadmill (Tretband). Model loads can be different.

Functional changes in the body of an athlete depending on the nature of the physical exertion. If the work is performed with a relatively constant power (which is characteristic of cyclic exercises performed on medium, long and long-standing distances), the degree of functional shifts depends on its level of its power. The greater the capacity of the work, the greater the consumption of oxygen per unit of time, minute volume of blood and respiration, heart rate, emission of catecholamines. These changes have individual characteristics associated with the genetic properties of the body: some individuals have a very pronounced reaction, and others are insignificant. Functional shifts also depend on the level of performance and sportsmanship. There are also sexual and age differences. With the same muscle power, functional shifts are more than less trained persons, as well as women compared to men and children compared to adults.

It should be noted that directly proportional to the dependence between the capacity and heart rate, which in adult trained persons is observed in the range from 130 to 180 t min min -1, and in the elderly - from 110 to 150 - 160 ot min -1 (Fig. 4). This pattern allows you to control the capacity of athletes at the distance, as well as it is the basis of various physical performance tests, since the registration of heart rate is most accessible in natural muscular activities.

Types of reactions on the background of exercise

It is very important when performing tests with exercise is the correctness of their execution and dosage by tempo and duration. When studying the reaction of the body on one or another physical exertion, pay attention to the degree of change in the determined indicators and the time of their return to the initial level. Proper assessment of the degree of reaction and the duration of recovery makes it possible to accurately accurately assess the status of the examined. According to the nature of the changes in the heart rate and blood pressure (blood pressure), after testing, five types of cardiovascular reactions are distinguished.

The normal type of the reaction of the cardiovascular system is characterized by the increase in the pulse, an increase in systolic and decrease in diastolic pressures. Pulse pressure increases. Such a reaction is considered physiological, because with normal pulse, the adaptation to the load occurs due to increasing the pulse pressure, which indirectly characterizes the increase in the impact volume of the heart. Systolic blood pressure reflects the effort of the left ventricle systole, and the decrease in diastolic is to reduce the tone of arteriole, providing better blood access on the periphery. Recovery period with this reaction of the cardiovascular system - 3--5 min. This type of reaction is typical for trained athletes.

The hypotonic (asthenic) type of reaction of the cardiovascular system is characterized by a significant increase in cardiac abbreviations (tachycardia) and to a lesser extent an increase in the impact volume of the heart, a slight rise in systolic and unchanged (or low increase) with diastolic pressure. Pulse pressure drops. This means that the increase in blood circulation during load is achieved more due to the increase in heart rate, and not an increase in the shock volume, which is irrational for the heart. The recovery period is delayed.

The hypertensive type of reaction to physical activity is characterized by a sharp increase in systolic blood pressure - up to 180-190 mm Hg. Art. With simultaneous lifting of diastolic pressure up to 90 mm RT. Art. and higher and significant pulse increase. The recovery period is delayed. Hypertensive reaction type is estimated as unsatisfactory.

The dystonic type of reaction of the cardiovascular system on physical activity is characterized by a significant increase in systolic pressure - above 180 mm Hg. Art and diastolic, which, after stopping the load, can dramatically decrease, sometimes to "0" - the phenomenon of infinite tone. Heavyness increases significantly. Such a physical activity reaction is regarded as unfavorable. The recovery period is delayed.

The step type of reaction is characterized by a stepped rise of systolic pressure at the 2nd and 3rd minutes of the reducing period, when systolic pressure is higher than in the 1st minute. This reaction of the cardiovascular system reflects the functional inferiority of the regulatory circulatory system, so it is evaluated as unfavorable. The period of recovery of heart rate and hell is delayed. Important in assessing the reaction of the cardiovascular system on physical activity is the recovery period. It depends on the nature of (intensity) of the load, from the functional state of the surveyed and other factors. The reaction to the physical activity is considered good when the pulse and blood pressure is noted with the normal initial data of the pulse and the ad is the restoration of these indicators on 2--3 pm. The reaction is considered satisfactory if the recovery occurs on the 4--5th minute. The reaction is considered as unsatisfactory, if hypotonic, hypertonic, dystonic and step reactions and the recovery period appear after the load, is delayed to 5 or more. Sustain the recovery of heart rate and blood pressure within 4--5 minutes. Immediately after the load, even at a normotonic reaction, as unsatisfactory should be assessed.

Hypertensive (atypical) reaction -pathophysiological response stress-reaction of the body on the impact of an excessive physical stressor. It is evidence of disadaptation of cardiovascular, nervous and other organism systems (state of the distress). This type of regulation occurs in athletes when overwork, disappointment, overtraining, subacuteous countries and other diseases. According to our observations, such a reaction is found in more than 80% of cases of atypical response.

At the same time, the pulse, usually rises to 180-230 wt. Min., What testifies to an excessive increase in the tone of the sympathetic department of the VNS. Sometimes, the pulse reaction to the load is completely normal - 170-174 wt. min. But, at the same time, there is an inadequate change in the magnitude of the systolic arterial pressure, which increases to 190 - 220 mm Hg. Often there is a "phenomenon of scissors", when the values \u200b\u200bof the pulse and systolic blood pressure differ significantly.

The diastolic pressure can be reduced or remain at the initial level is the best reaction option, within the framework of the hypertensive reaction. In more severe cases (overwork or overvoltage), diastolic pressure increases.

The restoration time of heart rate, the level of systolic and diastolic blood pressure (to the initial level) slows down significantly.

The hypertensive type of physical activity response takes place in violations of the vegetative regulation of the heart associated with the occurrence of prepactological and pathological conditions among athletes. This is a pathophysiological manifestation of a response stress reaction of the body, indicating an excessive deficiency of blood flow and oxygen on the periphery. The consequence of this deficiency is the excessiveness of hypoxia in muscle and other cells. Excessive hypoxia, in turn, overly activates the pathobochemical process - lipid peroxidation (floor). The final product floor is free radicals, which, in cases where their hyperproduction occurs, cells (cellular membranes, mitochondria, cells, ribosomes) cell enzyme systems damage or destroy or destroy the cells (cellular membranes).

The determination of the type of reaction of the cardiovascular system on the physical activity is an assessment of the direction and degree of severity of shifts of basic hemodynamic indicators (heart rate and blood pressure) under the influence of various types of physical loads, as well as their recovery speeds.
Depending on the direction and degree of severity of shifts, the magnitude of the heart rate and blood pressure, as well as the speed of their recovery, distinguish five types of reaction of the cardiovascular system for physical activity:

• Nimotonic
• Dystonic
• Hypertensive
• With a stepped increase in the maximum blood pressure
• Hypotonic

Nimothonic type reactions Cardiovascular system on physical activity is characterized by:

1. adequate intensity and duration of completed work with increasing heart rate;
2. an adequate increase in pulse pressure (the difference between systolic and diastolic blood pressure) by increasing systolic blood pressure and small (within 10-35%) reduction in diastolic blood pressure;
3. quickly (i.e., stacked at the given recreation intervals) Restoration of heart rate and blood pressure to starting values \u200b\u200b(after 20 squats - 3 min, after 15 runs at the maximum temperature - 4 min, after 3 minutes run at 180 steps in min - 5 min).

The normal type of reaction is the most favorable and reflects the good adaptability of the body to physical exertion.

Dystonic type reactionsAs a rule, it occurs after loads aimed at the development of endurance, and is characterized by the fact that the diastolic Hell is taking free to 0 (the phenomenon of "infinite tone").
When the diastolic blood pressure is returned to initial values \u200b\u200bfor 1-3 minutes of recovery, this type of reaction is regarded as an option of the norm; When preserving the "phenomenon of infinite tone" for a longer time - as an unfavorable sign.

Hypertensive type of reaction Characterized:

1. inadequate load with increasing heart rate;
2. inadequate load with an increase in systolic blood pressure to 190-200 mm Hg. (at the same time, the diastolic blood pressure is also somewhat rising);
3. slow down restoration of both indicators.

The hypertensive type of reaction indicates a violation of regulatory mechanisms, which causes a decrease in the economy of the functioning of the heart. It is observed in chronic CNS overvoltage (neurocirculatory dystonia according to hypertensive type), chronic overwriting of the cardiovascular system (hypertensive), in pre-and hypertensive.

Reaction with stepped increase in maximum hell Characterized:

1. sharp increase in heart rate;
2. continuing in the first 2 - 3 min rest with an increase in systolic blood pressure;
3. slow recovery heart rate and hell.

This type of reaction is unfavorable. It reflects the inertia of the regulatory systems and is registered, as a rule, after high-speed loads.

Hypotonic type reactions Characterized:

1. sharp, inadequate load with increasing heart rate;
2. the lack of significant changes in the Pide side of the blood pressure;
3. slow recovery heart rate.

The hypotonic type of reaction is the most unfavorable. It reflects the violation of the contractile function of the heart and is observed in the presence of pathologically changes in myocardium.

The results of the analysis of the dynamics of the type of reaction of the cardiovascular system on an additional check load, which is carried out before and after training (after 10 to 20 minutes), can be used with the aim estimates of urgent portability of training sessions.
As this control load, any functional sample (20 squats, 15 running on the spot at the maximum temperature, 1-3 minutes work on the cyergometer, in the step test, etc.) is usually used as this check.
The only requirement isstrict dosing load !!!

In this case, it is customary to allocate 3 reaction options:

• The first option is characterized by a non-essential difference of the reaction to an additional standard load, made after a sufficiently intensive training (classes), from the reaction to it to workout. There may be only small shifts of heart rate and blood pressure, as well as the duration of recovery. At the same time in some cases the reaction to the load after classes may be less pronounced, and in others more pronounced than before the classes. In general, this option shows that the functional state of the athlete after classes does not change significantly.
• The second version of the reaction indicates a deterioration in the functional state, which is manifested in the fact that after the occupation of the CSS shift as a reaction to an additional load becomes large, and the rise of hell smaller than before the class (the phenomenon "scissors"). The duration of the recovery of heart rate and blood pressure is usually increasing. This may be due to insufficient preparation of a dealing or pronounced fatigue caused by very large intensity and the volume of physical exertion.
• The third reaction variant is characterized by further deterioration of adaptability to additional load. After classes aimed at the development of endurance, a hypotonic or dystonic reaction appears; After speed-power exercises, hypertensive, hypotonic and dystonic reactions are possible. Recovery is significantly elongated. This reaction variant indicates a significant deterioration in the functional state of the involved. The reason is insufficient preparedness, overwork or excessive load in the class.
