Pohybové aktivity jako primární prevence

The dissertation deals with the iss. of physical activity in connection with primary prevention. It concerns particularly primary prevention of non-infectious diseases with massive incidence. It is important to know the principles that can contribute to the efficiency of nursing intervention in the area of physical activity. The model of stages of readiness for change plays a significant role here. The goal of the dissertation consisted in mapping the quality and quantity of exercise in ealthy population and its differences related to gender, age, education, and its role as a tool influencing the quality of health condition. Based on that goal, the following hypotheses were stated: Men and women differ in physical activity quality. Men and women differ in physical activity quantity. The quantity of physical aktivity decreases with increasing age in healthy population. The quality level of physical activity changes with the degree of education achieved. The quantity level of physical activity changes with the degree of education achieved. Further, the following research question was asked: How does physical activity contribute to bio-psycho-social aspects of life? The research within the dissertation was designed as quantitative-qualitative research. The selection set of the quantitative part consisted of 1122 respondents who constituted a representative set of adult population for the Czech Republic, according to the preset socio-demographic indicators. The data collection was performed in form of questionnaire research through the standardized short version of IPAQ questionnaire. The degree of dependence of selected categorial features was determined by chi-square test. Ordinal and cardinal data, after verification of normality by Shapiro-Wilk test, were processed with the help of non-arametric Mann-Whitney test, Wilcoxon paired test and Spearman non-parametric correlation. The qualitative research took place in form of a six-month experiment in which the research group (20 probands) was subject to intervention of physical activity, while the control group (34 probands) lived common life. Before and after intervention, subjectively perceived quality of life was measured in both groups with the help of selected questions of the standardized WHOQOL 100 questionnaire, and body composition was measured with the help of biolectrical impedance with Bodystat 1500 device. The research found that both men and women spend most of the day sitting. That fact is very probably related also to the Body Mass Index, showing an average value of 25.6 kg/m2 in the 1122 respondents, which is a value ranking in the category of overweight. It was proved that men are more active than women, preferring more intensive physical activity, which complies fully with statements of other authors. But an interesting fact is that the intensity and frequency of physical activity are influenced by education. Particularly respondents with university education are more active. On the contrary, age is related to decreasing intensity and frequency of physical activity, which is stated by other authors as well. The dissertation had four goals set and all of them were met. The five hypotheses were verified too. It can be stated that men and women differ in the quality and quantity of physical activity. It can also be stated that the level of quality and quantity of physical activity decreases with increasing age. And finally, it was shown that the quality and quantity of physical activity change also with the level of the education achieved. Regular physical activity contributes to improve the subjectively perceived psycho-social aspects of quality of life. They influence the body composition of the probands too. Nursing, considered an irreplaceable and self-standing scientific discipline, can contribute essentially to the development of active lifestyle not only of ill but also of healthy individuals
