Physical fitness of female students at University of South Bohemia
RŮŽIČKOVÁ, Lucie
In last several years the amount of physical activities during our day time seriously decreased. That phenomenon was caused by reduction of physically demanding works in our jobs and sitting way of spending free time. The result of the previous fact is population fitness worsening and consequently worsening of the labour productivity and health condition. The fitness is tightly connected with the relationship between a man and a movement and sporting activities. It should become the important part of the healthy life style and influence the formation of proper manners of every single man. The fitness is one of the markers of the cardiovascular system condition. And it is considered to be the certain sum of preconditions for optimal reaction on the stress of whatever cause. The regular training, the physical activity and the daily reasonable energetic income are the safest and the least economically demanding ways how to prevent civilisation diseases. The first task of the theses was to assess the fitness of women students of The University of South Bohemia. The fitness was assessed on the base of Ruffier?s test. The second task was to compare the fitness of several groups of students which represented every single faculty of The University of South Bohemia. The both tasks were completed. Two hypotheses were settled and confirmed in purpose to reach the goal of the theses. H1: The numerological value of the Rufier?s test of women students of the Faculty of Education is lower than the result of women from the other faculties. H2: Women students whose result of Ruffier?s test is 0-5 are spending more time by performing physical activity than other students. In this theses, Ruffier?s test as a non-direct way of assessing the fitness has been chosen to confirm the both hypotheses. Ruffier?s test is a simple test to asses the fitness which uses changes of the hearth rate before and after exercising. The test is based on the general premise that the hard body exercising which last for a longer period of time is connected with the rising of heart rate. The heart rate was recorded by sport tester. Heart rate values were set into the pattern for counting the index of Ruffier?s test and consequently classified. Averages of the Ruffier?s index of each faculty were measured and compared. The questionnaire was ad to the Ruffier?s index for better assessing the fitness of students. The questionnaire was composed by thirteen questions. Some of questions were of open and some of close type. The questionnaires were anonymous. Hypothesis H1 was confirmed. The average value of the Ruffier?s index for women students of the pedagogical faculty was 10,7. And the average value of the Ruffier?s index for women students of other faculties was 13. It means the average fitness of women students of pedagogical faculty is better than the average fitness of women students of other faculties. Hypothesis H2 confirmed the correlation between the time spending by physical exercising and the better fitness. The more times weekly women students exercise for more than 30 minutes a day the lower value of the Ruffier?s index they have. The assumption of the average values of the Ruffier?s index of those women from 0 to 5 was overstated. Women student in this project had the average values from 10 to 15 which mean worse values of fitness. Despite the worse values of Ruffier?s index, the correlation between the spending time by exercising and better fitness was confirmed. To sum up, there is a recommendation to compensate the simple monotone physical activity by wide spectrum of physical activities. The sport should be introduced into the life style. The person with a good fitness has less problems with movement, can work for a longer time without break, is strong and capable to fulfil everyday tasks with reserves. The process of improving the fitness is a run for a long distance but it should be the goal of all people no matter of how old they are.

Comparison of the effects of aerobic and yoga activities among university studets.
KULICH, Miloslav
This thesis deals with comparing aerobic exercise and yoga, due to improved levels of fitness in one semester for students of Pedagogical University of South Bohemia in the Czech Budejovice. Using content analysis of editorial resources, I compiled a theoretical part where I try to clarify the effects of yoga and aerobic exercise on physical fitness level. Also I am trying here to clarify the factors adversely affecting the ability, particularly in relation to higher education. In the practice of comparing the effects of both activities at the level of physical fitness through tests and measurements Ruffierovy resting heart rate.

Doppler measurement of vessel parameters
NÁTHEROVÁ, Markéta
Ultrasound investigation is the most common and most readily available current advanced diagnostic method. Ultrasound can be used to track and image moving structures such as cardiac valves or flowing blood {--} these methods are based on the so-called Doppler phenomenon. Using the Doppler phenomenon, it is possible to determine the velocity and direction of movement of the measured object. The objective of this work was to track the changes of vascular flow and pulse rate depending on the degree of tolerance of exercise attained by the test persons, the stress (load) and ambient temperature changes. For this purpose, 2 groups were defined where the first group consisted of individuals adapted to the stress, while the members of the second group were untrained. To measure the vascular parameters we used a Doppler meter, HiDop 300. The LCD display of the instrument, or alternatively the monitor of a connected computer, provide images of the measured spectral Doppler curve as well as its parameters (heart rate HR, resistance index RI, pulsatility index PI, systolic/diastolic ratio, mean frequency). The work is concerned with the impact of physical load and cold-related stress on the circulatory system in the vessels. The haemodynamics of the vascular system depends on the type and intensity of the load. The formulation of results of the work, however, must account for a number of internal factors (age, sex, health {\dots}) and external factors (ambient temperature, air flow {\dots}) that are themselves associated with various changes in the circulatory system. For example, reduction of peripheral vascular contractility in the elderly, disruption of vascular wall elasticity by depositing fatty substances or increased heart rate due to the stress stimulus. The main advantage of a Doppler instrument and all ultrasound methods is to be seen in the fact that it is a non-invasive method, and has no adverse effects on the investigated person, such as the effects associated with roentgen radiation, provided, however, that appropriate intensity of ultrasound radiation has been chosen.

Baroreflex sensitivity and heart rate
Halámek, Josef ; Jurák, Pavel ; Swenne, C. A. ; Kára, T. ; Souček, M. ; Eisenberg, M. ; Nykodým, J.
The correlation between baroreflex sensitivity (BRS) and heart rate (HR) is discussed. According to theoretical model, where the constant blood flow is supposed, the BRS given in [ms/mmHg] must correlate with HR and BRS in [mHz/mmHg] should not correlate with HR. This assumption was confirmed by the measurement on healthy young subjects, but it is not valid for old healthy subjects and for patients.
