Purpose: This paper presents the results of a comparative and dependency analysis between physical activity, joy of physical activity and quality of life in female high school students with different levels of sport performance. Methods: The survey was attended by (n = 560) 16–19 years old high-school students. The quality of life was monitored using the modified SQUALA questionnaire, the joy of physical activity using the PACES questionnaire and the level of physical activity during the week in hours (PA). The data are presented by means of descriptive characteristics (n, M, SD) and statistical significance and dependencies respectively are assessed using nonparametric methods (W, U, rs) on significance levels (p < ,10; p < ,05 and p < ,01). Results: The results of the dependency analysis did not show a large number of interactions between the PA, PACES and SQUALA among high-school female students. We found the interactions between the PA and PACES or SQUALA sporadically in groups of girls with the different levels of sports, where positive interactions predominated. PA in the week is positively correlated with PACES (rs = ,218, p < ,10) only in registered female athletes. Positive interactions between PACES and SQUALA can be found in top female athletes (material well-being p < ,10; education p < ,05; free time p < ,01) and in occasional female athletes (physical well-being p < ,20; psychosocial well-being p < ,20; appearance and ownership of things p < ,20). Conclusions: The results confirm the importance of voluntary and organized physical activity in the life of high-school students, who have the potential to increase the level of satisfaction with activity.The paper was published from the grant of the Ministry of Education KEGA 003 UKF-4/2016.
Introduction. The purpose of this paper is to extend the existing knowledge about physical fitness of the current school population aged 11-15 and identify the relationships between physical fitness and body components. Material and Methods. The research was held with the participation of 375 elementary pupils (5-9 grade). All measurements were done under identical conditions and were the part of the HBSC (Health and Behavior of School Age Children) study. The evaluation of physical fitness was done with the Ruffier test and SUUNTO POD testers were used to measure the heart rate. The data on body components were acquired with a bioimpedance diagnostic device InBody 720. Results. The results pointed to a lower physical fitness in girls (Ruffier index of 15.80 ± 4.2) than boys (14.78 ± 4). When comparing the individual grades, the level of physical fitness increased in boys and girls with the increasing age in the seventh grade and subsequently decreased, and the differences were statistically significant (p < 0.05). In the analyzed schools, the Ruffier index values were within the range of 13.9 ± 3.8 to 16.1 ± 4.5, and the differences between them were statistically significant (p < 0.05). The parameter values for body components followed the trend in the Ruffier test. The regression analysis showed that physical prowess is affected by body fat mass to 9.67% and total body water to 1.21%. Conclusions. Young generation at age 11 to 15 years reaches lower physical fitness in comparison with the past. Boys have higher level of physical fitness than girls and the size of the city affects body composition and physical fitness. Parameters of body composition are in relation with Ruffier index. Body fat mass and total body water explaining the results of Ruffier test.
