Type of Research Project
- Clinical Project without Laboratory work
What is the background of the project?
The actual direction of fundamental and applied physiology and medicine is the study of the mechanisms of regulation and functional interactions between regulatory systems in order to assess the adaptive capabilities of the human body. Studying the basics of functional diagnostics of an organism of healthy people will allow future doctors to assess the state of health and adaptation of the organism, the level of its functioning according to the degree of deviation of physiological functions from the norm. Participation in this project will allow students to more deeply study the general laws of vital activity of a healthy organism, methods for studying the cardiorespiratory system of the organism, which is of great importance for the subsequent mastery of preclinical and clinical disciplines.
What is the aim of the project?
The aim of the project is to improve knowledge about the basic laws governing the operation of individual systems of the body of a healthy person and a mastery of modern methods of functional diagnostics of individual systems of the organism for understanding the functional disorders.
What techniques and methods are used?
Two groups of students will be selected - the control and the studied ones. Students with good physical training will be included in the Study Group, the control group will include those who do not perform physical activity on a daily basis. Methods to assess the functional state of the cardiovascular and respiratory systems: 1. Integral assessment of the functional state of the cardiovascular system. Electrocardiography. Record and analysis of electrocardiogram in 12 leads at rest and when conducting stress tests (Analysis of heart rate regularity, Calculation of the number of heartbeats. Determination of the excitation source, Evaluation of the conduction function, Determination of the electrical axis of the heart) 2. Integral assessment of the functional state of the external breathing apparatus. Spirography, spirometry, pneumotachometry. 3. Functional tests will be used to assess the state of the cardiovascular system. Functional tests: Martine-Kushelevsky's test - 20 squats in 30 seconds. Bicycle ergometry. Bicycle ergometry allows precise dosing of muscular work, to carry out loads in a wider range of power, it is easy to achieve submaximal heart rate 4. During the study, the method of variation pulsometry according to R.M. Baevsky will be used. It is necessary to investigate cardio intervals using an electronic cardiograph (Poly-Spectrum-8 / EX of Neurosoft Company), moderate exercise will be simulated on a cardiovascular machine (KETTLER). Previously, all students will be determined health coefficient by the modified formula R.M. Baevsky. The algorithm for mathematical processing of cardio intervals includes the calculation of mode (Mo), mode amplitudes (AMo), autonomic equilibrium index (AEI), vegetative rhythm indicator (CDR), regulation adequacy index (RAI), and stress index of regulatory systems (INRS). The reliability of the differences in the data obtained will be determined by student's criterion. The peculiarities of changes in the balance of the autonomic nervous system divisions in students will be determined by the method of sigmal deviations, where three types of autonomic regulation were indicated: parasympathicotonic, normotonic, sympathicotonic.
What is the role of the student?
- The student will mainly observe
- The student will observe the practical experiments but will be highly involved in the analysis of the results
- The tasks of the student will be performed on his/her own
- The tasks will be done under supervision
What are the tasks expected to be accomplished by the student?
1) determine the blood pressure before, during and after the physical test 2) record and interpret the parameters of external respiration using a spirometer Spiro C-100: determination of vital capacity and its components at rest and after exercise, determination of forced vital capacity, its speed and temporal characteristics at rest and after exercise. 3) registration and analysis of electrocardiography in standard leads at rest and physical activity and explain the genesis of the constituent elements of a normal ECG, analyze, interpret and execute electrocardiological conclusion conclusion. 4) carry out functional testing (Martine-Kushelevsky's test (20 squats in 30 seconds), Bicycle ergometry with a research group of local students. The Martin-Kushelevsky test allows us to estimate the rate at which an organism adapts to physical activity, and also to clarify the time required for recovery processes. In other words, the Martinet test determines the ability of the cardiovascular system to recover from a workout. The results of the studies will be processed statistically with the calculation of the mean values, standard errors, the values of the Student's criterion and the pair correlation coefficient using the generally accepted recommendations. The data will be processed on a computer using the methods of correlation statistics (in the MicrosoftOfficeExcel program).
Will there be any theoretical teaching provided (preliminary readings, lectures, courses, seminars etc)
Yes Lectures: 1. Functional diagnosis of external respiration. 2. Functional methods of the study of the heart (ECG). 3. Health assessment using functional diagnostic methods.
What is expected from the student at the end of the research exchange? What will be the general outcome of the student?
- The student will prepare a scientific report
- The student’s name will be mentioned in a future publication
What skills are required of the student? Is there any special knowledge or a certain level of studies needed?
- to have a basic knowledge about the regulatory systems of the body; - Be able to use a special scientific and reference literature on the evaluation of adaptation capabilities of the organism; - to have the skills to interpret the data obtained in the course of research work
Are there any legal limitations in the student’s involvement
