The Impact

Studies of the functional state of the respiratory system have been widely used to assess the adaptive reserves of the human body. The functional state of the respiratory system is closely related to the functional characteristics of systemic and regional hemodynamics, functional reserves of the blood system. With changes in the social status of a person, the adaptive potential of his body can significantly decrease. Reliable markers of the limitations of adaptive potential in people of different ages are the decrease in the values of the main pulmonary volumes in the conditions of physiological rest and when performing test load tests. The negative dynamics of forced expirations due to the decrease in the strength of the auxiliary respiratory muscles and changing depending on age was established. The presence of this undesirable phenomenon can be a marker of reducing adaptation reserves in the study of the impact of environmental factors on the phenomenon of premature aging.

The article provides the results of determining the level of physical development of the 1th-2nd course students of design specialties of the College of Construction, Architecture and Design. The physical development of students was determined by indicators of harmony of the bodybuilding (Kettle index 2), functional state of the cardiovascular system (Ruffier index), and respiratory system (Stange test). Length and weight of the body, heart rate, breathing delay time were measured. As a result of the researches, the “average” level of the physical development is determined in the 1th-2nd course girls and “sufficient” - in boys. Thus, mass-growth indicators of students according to the calculation of Kettle 2 index, both boys and girls correspond to the assessment of 5 points, which indicates a harmonious physique of students; indicators of the functioning of the cardiovascular system (Ruffier Index) of 1st year boys and the 2nd year students make 2 points, which corresponds to the ”below average” level, and the results of the 1st year girls equal to the assessment of 3 points, “average” level; indicators of the functional state of the respiratory system (Stange test) of boys of the 1th-2nd  course correspond to the assessment of 4 points (“above the average” level), and girls of both courses - 3 points (“average” level). In the age and gender aspects, physical development indicators, in general, don’t significantly differ with the general tendency to increase results with age and the dominance of boys over such in girls. The exception is the Ruffier index, where there is an opposite trend - the results decrease with age in girls and they are higher than in boys. Thus, the results of the research indicate the feasibility of introducing the 1th-2nd course students of professional pre-high education of special physical exercises into the process of physical education to improve the functional state of the cardiovascular and respiratory systems.

Homeostatic Response

In the healthy, untrained young adult, a case is made for a respiratory system (airways, pulmonary vasculature, lung parenchyma, respiratory muscles, and neural ventilatory control system) that is near ideally designed to ensure a highly efficient, homeostatic response to exercise of varying intensities and durations. Our aim was then to consider circumstances in which the intra/extrathoracic airways, pulmonary vasculature, respiratory muscles, and/or blood-gas distribution are underbuilt or inadequately regulated relative to the demands imposed by the cardiovascular system. In these instances, the respiratory system presents a significant limitation to O2 transport and contributes to the occurrence of locomotor muscle fatigue, inhibition of central locomotor output, and exercise performance. Most prominent in these examples of an “underbuilt” respiratory system are highly trained endurance athletes, with additional influences of sex, aging, hypoxic environments, and the highly inbred equine. We summarize by evaluating the relative influences of these respiratory system limitations on exercise performance and their impact on pathophysiology and provide recommendations for future investigation.

Human Respiratory System

Scientific relevance and purpose. This research looks at the urgent task of modeling the structure of the human respiratory system and processes occurring in it, in order to predict the changes in physiological parameters occurring under different mechanical actions. Results. This paper suggests mathematical model based on the description of equations of the mass flow and mass flow rate in the pulmonary channels in cases, when airways are branched in accordance with the prin-ciple of regular dichotomy with regard to the equations of work dynamics of the respiratory muscles and the ability to model different stresses in the breathing circuit, caused by trainers. The research examined the stresses generated by muscles in the radial and axial direction of the equivalent hollow cylinder, which represented the chest with regard to the elastic stress component in the cylinder wall and variable muscle stress in the circumfe-rential direction. The paper contains the results of mathematical modeling of breathing without stress, the graphs of volume and mass flow in lungs generations and pressure-flow diagram. Conclusions. The developed mathematical models enable more precise multi-parameter modeling of the dynamics of functioning of complex biotech system "respiratory muscles trainer - human", which enables the implementation of the prediction of shifts of physiological and mechanical properties from the values of the normal process and to adjust the control actions on this basis

Wall Compliance

Development of chest wall stiffness between infancy and adulthood has important consequences for respiratory system function. To test the hypothesis that there is substantial stiffening of the chest wall in the first few years of life, we measured passive chest wall compliance (Cw) in 40 sedated humans 2 wk-3.5 yr old. Respiratory muscles were relaxed with manual ventilation applied during the Mead-Whittenberger technique. Respiratory system compliance (Crs) and lung compliance (Cl) were calculated from airway opening pressure, transpulmonary pressure, and tidal volume. Cw was calculated as 1/Cw = 1/Crs - 1/Cl during manual ventilation. Mean Cw per kilogram in infants < 1 yr old was significantly higher than that in children > 1 yr old (2.80 +/- 0.87 vs. 2.04 +/- 0.51 ml.cmH2O–1.kg-1; P = 0.002). There was an inverse linear relationship between age and mean Cw per kilogram (r = -0.495, slope -0.037; P < 0.001). In subjects with normal Cl during spontaneous breathing, Cw/spontaneous Cl was 2.86 +/- 1.06 in infants < 1 yr old and 1.33 +/- 0.36 in older children (P = 0.005). We conclude that in infancy the chest wall is nearly three times as compliant as the lung and that by the 2nd year of life chest wall stiffness increases to the point that the chest wall and lung are nearly equally compliant, as in adulthood. Stiffening of the chest wall may play a major role in developmental changes in respiratory system function such as the ability to passively maintain resting lung volume and improved ventilatory efficiency afforded by reduced rib cage distortion.
