Type of Research Project
- Basic science
What is the background of the project?
The problem of hypodynamia becomes one of the most common in our modern society. The survival movement stopped being a necessity. Scientific and technical progress assists the “modern human” to establish a comfortable life condition without any physical effort. Hypodynamia can cause serious consequences, that are projected onto cardiovascular system and human’s organs. Identification of people with hypodynamia and research of their general vital signs, will aid us to identify risk groups on pre-nosological stage for non-medication correction. This project is devoted to an actual problem of studying the functionality of the human cardiovascular system. The purpose of the project is to study the effect of physical activity on the indicators of the central hemodynamic of patients
What is the aim of the project?
The aim of the project is to investigate the influence of physical work load as an indicators of the central hemodynamic situation such as blood pressure, heart rate, stroke and cardiac output of medical students with and without hypodynamia by rheography
What techniques and methods are used?
1) Profiling group of medical students( male and female) for hypodynamia symptoms. 2) Determine the heart rate per minute and blood pressure of the patients in three stages: rest, load on 10 sit-ups and 20 sit-ups. Blood pressure will be measured using dial indicators of tonometer according to the method of Korotkoff. 3) Calculate systolic blood volume(SBV) and cardiac output(CO ) in testers 4) Determine relationship between the values at the state of rest and after physical activity by the help of the Wilcoxon method 5) Identify differences between male and female students’ parameters using Mann-Whitney method. To assess the effect of physical activity on the hemodynamic parameters techniques such as Rheography and ECG(electrocardiograph) will be used.
What is the role of the student?
- The student will observe the practical experiments but will be highly involved in the analysis of the results
What are the tasks expected to be accomplished by the student?
Tasks that student has to perform on his/her own: Profiling group of medical students for hypodynamia symptoms, determining the heart rate per minute and blood pressure of the patients in three stages: rest, load on 10 sit-ups and 20 sit-ups. Work that will be done under supervision of the tutor: Calculation of systolic blood volume(SBV) and cardiac output(CO ), work with ECG(electrocardiograph) and Rheograph.
Will there be any theoretical teaching provided (preliminary readings, lectures, courses, seminars etc)
The student will receive theoretical teaching (lectures, presentations, and seminars.
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 presentation
- The student’s name will be mentioned in a future publication
- The student will have the opportunity to present the results together with the supervisor at a conference
What skills are required of the student? Is there any special knowledge or a certain level of studies needed?
Have a basic knowledge about haemodynamics · Should be competent in the electrocardiogram recording equipment, be able to explain the genesis of the constituent elements of a normal ECG, analyze, interpret and execute electrocardiographically conclusion · Experience of working with a Rheograph · Student should have skills of measuring blood pressure · Be able to use a special scientific and reference literature · Have the skills to interpret the data obtained in the course of research work · To be able to report about the results obtained at the student conference
Are there any legal limitations in the student’s involvement
