Indexes of hemodynamics in a dosage of physical activity in girls against the background of low systolic blood pressure

Abstract

Annotation. Purpose: to examine the state of hemodynamics, blood oxygenation levels in girls with hypotensive type neurodystonia in a dosed physical load. Material: The study involved 59 women with hypotensive type neurodystonia aged 18-19 years and 14 healthy women the same age. Results: It was found that the girls on the background of low systolic blood pressure observed early hemodynamic response from the very first steps (25-50 W) bicycle stress test in the form of increased heart rate, stroke volume, pulse pressure. At the height of the stress test in 76.27 % of girls showed a reduction in blood oxygenation indices and lengthening of the period of recovery. Conclusions: The dose of girls in physical activity with hypotension, place high demands on the cardiovascular system, the restructuring of which is accompanied by inadequate oxygen supply systems in operation, adjustment disorder, low capacity for work that requires a non-drug methods of rehabilitation in the form of regular dose of physical activity, breathing exercises .

Comparative characteristic of correlation between pulse subjective indicators of girl students’ and school girls’ reaction to physical load

“…In this connection application of informative and effective methods of control over organism's functional state acquires great importance. Such approach is required for adequate regulation of physical loads depending on human individual features [23,35,37,44,47]. It should be noted that determination of adults' and children's reactions to physical load by subjective feelings as well as their physiological parameters becomes very important [8].…”

Functional systems of students’ organism depending on physical fitness to physical load

“…In this respect cardio vascular system (CVS) and erythrocyte link of homeostasis are the weakest [1,11]. Vegetative and neuro motor regulation of nervous muscular system (NMS) has a number of general systemic structural functional properties, which naturally reflect in state of Ер [44,46].…”

Special aspects of hemo-dynamic and reaction of erythrocytes in blood to standard physical load of different qualification female volleyball players

“…Typological analysis [2,9,11] showed that 42% of the tested female volleyball players have hypo-kinetic, 31% -eukinetic and 27% -hyper-kinetic type of CHD.…”

“…The authors offer the program of Nordic walking (12 weeks, thrice a week) [38]; − Nordic Walking reduces resistance to insulin [40]; − Nordic Walking significantly reduces ferritine concentration in blood that explains the registered reduction of iron in organism [39]. As some specialists point non uniformity of CHD types is conditioned by body constitution and is a physiological norm of health [2,6,9]. Study of EPB changes with PL max , depending on CHD type is still out of scientists' attention.…”

“…Studies of CHD types in children resulted in idea that they are genetically determined [12]. But not equal percentage of these types in different age groups contradicts to it [3,9,14]. With it, the question about special aspects of CHD and EPB reactions to single standard physical load, depending on athletes' sportsmanship and CHD type still remains to be out of specialists' attention [6,8].…”
