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.
The aim of the study was to find out if subtoxic doses of fenitrothion (0.1 LD₅₀, LD₅₀ =166.6 mg/kg) administered to mice exposed to transient oligaemic brain hypoxia induced by bilateral clamping of the carotid arteries (BCCA) influence memory processes, movement activity, and coordination. The BCCA was carried out under ketamine + xylazine anaesthesia. Common carotid arteries were clamped for 30 min. Twenty-four hours later; the animals were injected intraperitoneally with 0.1 LD₅₀ of fenitrothion. Controls and sham-operated animals (with carotids separated but not clamped) were injected with respective volumes of bidistilled water. All the animals were trained in passive avoidance (PA) task. The examination of memory retention in PA was done 24 h later followed by testing of fresh spatial memory in a Y- maze, movement co-ordination, and spontaneous movement activity in a 30-min period. Fenitrothion did not significantly alter memory processes in the examined mice. However, the movement coordination was significantly impaired in animals that underwent BCCA alone as well as being oligaemic and under the influence of fenitrothion vs control groups. The same groups demonstrated significantly impaired spontaneous movement activity vs controls.
The purpose of the present study was to examine whether the effects of exposure to 0.1LD₅₀ of bifenthrin on memory processes, movement activity, and coordination could be exacerbated by transient reduction of cerebral oxygen supply. The transient occlusion of both common carotid arteries (BCCA) in adult mice was performed under anaesthesia. Intraperitoneal LD₅₀ for bifethrin was estimated to be 16.1mg/kg b.w. The memory retention was evaluated in a step-through passive avoidance task (PA), working spatial memory in a Y-maze, movement coordination on a rota-rod, and movement activity in an automated device. Long-term memory impairment caused by bifenthrin was exacerbated by BCCA. Movement co-ordination was significantly altered in animals treated with the compound. Movement activity was slightly decreased in animals after BCCA and pesticide injection. These results indicate that cerebral oligaemic hypoxia potentiates long-term memory impairing effect of bifenthrin.
