INTRODUCTION AND OBJECTIVE: Participation of adolescents in organized physical activity (PA), together with physical education, is essential for the development of a habit of regular PA, achievement of PA recommendations and adoption of physical literacy. The aim of the study is to identify the trends and differences in PA levels between adolescents participating in organized team PA, organized individual PA, and those not participating in organized PA. Another aim is to formulate proposals to eliminate the negative effects of the pandemic on adolescents' participation in organized PA. MATERIAL AND METHODS: The research took place between 2012-2021 in 51 secondary schools and involved a total of 1,202 boys and 1,561 girls. Participation in organized PA was examined using the 'Sports preferences survey'. Weekly PA was investigated by means of the 'International Physical Activity Questionnaire-Long Form'. RESULTS: The results confirmed the negative trend in participation in organized PA. However, this was predominantly caused by the negative effects of the pandemic in 2020-2021. Boys participating in organized team and individual PA had more school PA, recreation PA, vigorous PA, moderate PA and overall PA during the week, compared with boys not participating in organized PA (girls had more vigorous PA, moderate PA and overall PA). CONCLUSIONS: Participation in organized team PA and individual PA plays an important role, primarily in supporting vigorous PA but also in overall weekly PA among boys and girls. The negative effects of the pandemic should be eliminated by increasing adolescents' participation in various forms of organized PA with an emphasis on organized individual PA which can be regularly pursued, even under restrictive measures at home, in the countryside or in nature.

OBJECTIVES: The overall aim of the research is to gain insight into the lifestyle and health behaviour of young people with disabilities aged 12-18 years, and to learn about the factors shaping their health. In this study, our aim was to investigate the eating habits and physical activity of adolescents with disabilities and the influencing factors. METHODS: The study's source population was young people aged 12-18 with disabilities in the Szabolcs-Szatmár-Bereg County. A total of 239 completed questionnaires were processed and analysed. Boys were overrepresented in the study. RESULTS: The results show that inadequate eating habits also exist in the population we studied, the consumption of certain foods correlates with the education level of parents. A more secure social background is a protective factor in terms of physical activity. The survey was made with the aim of intervention much needed. With precise knowledge of the health behaviour of the target group, our goal is to develop a complex intervention programme adapted to the needs of children with disabilities. CONCLUSION: The eating habits of adolescents with disabilities in the Szabolcs-Szatmár-Bereg County are unsatisfactory. Experience and results show that differentiated health promotion of young people with disabilities is necessary.

OBJECTIVES: Many studies draw attention to the negative consequences of the pandemic or lockdown on the well-being and lifestyle of different sections of the population. This study considers whether changes occurred in dietary regime and level of physical activity during three periods - before the pandemic, during the lockdown, and during the present in older Slovak adults. We also investigate whether individual weights changed during the pandemic. METHODS: The study has a cross-sectional design. We collected 436 questionnaires from older adults (60+) living in Slovakia; 277 come from the first phase of online data collection (04/2022-06/2022) in university students of the third age, and 159 from the second phase of offline collection (07/2022-11/2022) in social service facilities. We monitored if there were any changes within the observed periods in the variables of diet regime, physical activity, and BMI. The database has been processed in IBM SPSS Statistics. RESULTS: During the lockdown, the frequency of physical activity decreased (p < 0.001), the quality of movement worsened (p < 0.001), and the time respondents devoted to physical activity during the week decreased (p < 0.001). At present, the variables have increased. Within the dietary regimen, statistically significant changes occurred in appetite and non-alcoholic beverage intake (p = 0.002). However, there were no significant changes in the number of daily meals (p = 0.190), or the amount of alcohol consumed (p = 0.066). The BMI of older men and women did not change after the pandemic (p = 0.519), and it did not differ between men and women either before the pandemic (p = 0.281) or after it (p = 0.449). Also there is no difference between UTA students and social facility living seniors before the pandemic (0.933) and now (0.317). The results showed that even though physical activity significantly decreased during the lockdown, the older adults in our study did not eat more during the lockdown, nor did they gain weight. However, this probably had negative consequences for the quality of their movement. CONCLUSION: It is essential to simultaneously create compensatory measures while implementing future anti-epidemic (or other) measures. They would help maintain the desired amount of physical activity or other healthy habits on an optimal level.

The negative impact of the COVID-19 pandemic and distance education has significantly affected adolescents' lives. The restrictive policies negatively affected their physical and mental health and life satisfaction. It is therefore desirable to look for ways to eliminate similar negative impacts on adolescents in the future. This study aimed to identify the differences in the association between physical activity and life satisfaction in Polish adolescents before and during the pandemic. The study included 1541 participants (891 before the pandemic and 650 during the pandemic) aged 15-19 years. The International Physical Activity Questionnaire-Long Form questionnaire was used to assess physical activity, and the Bern Subjective Well-Being Questionnaire was used to evaluate life satisfaction. The objectivity of data collection and analysis before and during the pandemic was ensured by the web application the International Database for Research and Educational Support. During the pandemic, we found lower physical activity and life satisfaction in both boys and girls compared to before the pandemic. Girls with low and high physical activity levels showed significantly lower life satisfaction during the pandemic than they did before. Low life satisfaction was associated with lower physical activity, and high life satisfaction was associated with greater total physical activity. Both boys and girls with low and high life satisfaction achieved significantly fewer physical activity recommendations during the pandemic. High life satisfaction increased the likelihood of meeting the recommendations for physical activity before and during the pandemic. This study provides new insights into the differences and associations between life satisfaction and physical activity in adolescent boys and girls before and during the pandemic. It provides suggestions for the prevention of possible future restrictions in the school settings. Support for post-pandemic life satisfaction in adolescents should focus mainly on increasing vigorous physical activity and improving adolescent participation in organized physical activity settings.

The author evaluates the importance of different vitreoretinal factors and the role of indirect injury in the pathogenesis of detachment of the retina/DR/and holds the following view as regards subjects inclined to pursue physical activity. Numerous and frequent vitreoretinal risk factors are a forecast of DR only in a small fraction of patients. Indirect injury is not recognized as a cause of DR. Risk factors incl. medium-grade and high-grade myopia are not an indication for restriction of physical activity nor for Caesarean section in pregnant women. Restriction of physical activity acts as a psychic trauma and does not prevent the development of DR.

AIMS: A reduction of habitual physical activity due to prolonged COVID-19 quarantine can have serious consequences for patients with cardiovascular diseases, such as heart failure. This study aimed to explore the effect of COVID-19 nationwide quarantine on accelerometer-assessed physical activity of heart failure patients. METHODS AND RESULTS: We analysed the daily number of steps in 26 heart failure patients during a 6-week period that included 3 weeks immediately preceding the onset of the quarantine and the first 3 weeks of the quarantine. The daily number of steps was assessed using a wrist-worn accelerometer worn by the patients as part of an ongoing randomized controlled trial. Multilevel modelling was used to explore the effect of the quarantine on the daily step count adjusted for weather conditions. As compared with the 3 weeks before the onset of the quarantine, the step count was significantly lower during each of the first 3 weeks of the quarantine (P < 0.05). When the daily step count was averaged across the 3 weeks before and during the quarantine, the decrease amounted to 1134 (SE 189) steps per day (P < 0.001), which translated to a 16.2% decrease. CONCLUSIONS: The introduction of the nationwide quarantine due to COVID-19 had a detrimental effect on the level of habitual physical activity in heart failure patients, leading to an abrupt decrease of daily step count that lasted for at least the 3-week study period. Staying active and maintaining sufficient levels of physical activity during the COVID-19 pandemic are essential despite the unfavourable circumstances of quarantine.

BACKGROUND: Little is known about the effects of physical activity and fitness on sleep timing parameters in adolescence. METHODS: We investigated the development of sleep timing between age 8 and 15 and its association with physical fitness at age 15 in 787 adolescents (408 males, 379 females). Physical fitness was measured using the physical work capacity (PWC) protocol. Information on sport activity was collected at ages 11 and 15. Finally, the contribution of other covariates (sex, body mass index (BMI), parental education and occupational skill level) to the association between sleep parameters and physical fitness was evaluated. The correlation of BMI and physical fitness was assessed separately. RESULTS: Mild correlation of sleep duration at ages 8 and 15 was observed (r=0.08-0.16). Higher sport activity participation and physical fitness were found to be mildly associated with delayed bedtime and reduced sleep duration; the association with bedtime was significant after adjustment for all covariates. Sport activity at age 11 was not associated with sleep timing at age 15. Interestingly, higher BMI was linked to delayed bedtime and higher physical fitness. CONCLUSION: Our findings do not support existing hypotheses suggesting the association of low physical activity and fitness with shorter sleep duration and high BMI in a generally non-obese adolescent population without severe sleep restriction.

In the European Union, Czech Republic ranks 3rd and 6th for the incidence of obesity and cardiovascular diseases, respectively. Worldwide, short sleep duration and excessive daytime sleepiness (EDS) characterize obese subjects, which in turn exhibit scarce physical activity and unhealthy diet. We aimed to understand the relationship between irregular sleep patterns, obesity and lifestyle factors, such as diet and physical activity, in a vulnerable Czech population. 1482 members of the Kardiovize cohort, a random sample of the Czech urban population, were included in a cross-sectional study. Exposure variables included self-reported sleep duration and EDS, assessed by the Epworth Sleepiness Scale. Primary outcomes were BMI and waist-to-hip ratio or prevalence of obesity and central obesity. Covariates included physical activity and diet. Associations and interactions between variables were evaluated using logistic regression analyses. After adjustment for covariates, short sleep duration (<7 h) was associated with greater odds of overweight (BMI > 25; OR = 1.42; 95%CI = 1.06⁻1.90; p = 0.020) and obesity (BMI > 30; OR = 1.40; 95%CI = 1.02⁻1.94; p = 0.047), while EDS was associated with greater odds of central obesity (OR = 1.72; 95%CI = 1.06⁻2.79; p = 0.030), independent of diet and physical activity. However, due to the cross-sectional nature of our study, further prospective, large-scale studies are needed to evaluate the etiological link and causality between sleep disturbances and obesity.

BACKGROUND: Physical activity (PA) during the school day is crucial for the health and well-being of adolescents. This study examines the impact of the COVID-19 pandemic on youth PA patterns to better understand these changes and to provide guidelines for school programming. METHODS: Differences in PA within specific segments of the school day were examined before and after the pandemic using the Youth Activity Profile questionnaire. Participants included 956 boys and 1,317 girls from 21 high schools. The study involved 12 Czech and 9 Polish high schools before the pandemic and 9 Czech and 8 Polish high schools after the pandemic. RESULTS: Both Czech and Polish boys and girls exhibited significantly less transportation PA to and from school and reduced PA during the school day after the pandemic compared to before. Additionally, Czech and Polish boys were significantly less physically active during school breaks, and Czech boys and girls had notably less PA during physical education lessons. The pandemic disrupted the habit of regular PA on school days, particularly evident in the decline of PA to and from school. CONCLUSION: The study confirms a significant difference in PA of Czech and Polish adolescents in various segments of the school day after students return to school following pandemic restrictions. Promoting achievement of the recommendations in the segments of the school day and in comprehensive school PA programs should be an important part of school health and education policy and public health promotion for adolescents.

BACKGROUND: Lockdowns amid the COVID-19 pandemic drastically reduced the possibility of undertaking physical activity (PA) in gyms, swimming pools, or work-related PA, e.g., active commuting. However, the stay-at-home order could have reduced PA the most, i.e., the ban of unnecessary outdoor activities. It affected free walking, running, skiing, active tourism, etc. It is, therefore, crucial to estimate how the stay-at-home order affected PA. We estimated how the stay-at-home order affected perceived PA and sedentary behavior compared to the pre-pandemic time in Poland. METHODS: We used a self-reported International Physical Activity Questionnaire-Long Form (IPAQ-LF) to estimate the time (minutes per day) of vigorous and moderate PA and walking and sitting time. RESULTS: We gathered data from 320 Polish participants. Bayesian approaches, including t-test and Bayesian correlations, were used to find differences and correlations between PA before and during the stay-at-home lockdown. Our data supported the hypotheses that vigorous PA, as well as walking, declined during the lockdown. Surprisingly, our data did not support the hypothesis that moderate physical activity was reduced. We found that moderate PA during lockdown increased compared to the pre-lockdown PA. As hypothesized, our data strongly evinced that sitting time inclined during the lockdown. PA decline was not correlated with the available living space. People who had access to gardens did not demonstrate a higher PA level than those without. DISCUSSION: Walking and sitting time have drastically changed during the stay-at-home lockdown, decreasing and increasing, respectively. Given results from studies focusing on lockdowns without the stay-at-home restriction, it may be assumed that letting people go outside is crucial in keeping them more active and less sedentary. Authorities should take into account the effect the stay-at-home order may have on PA and sedentary behavior and as a result, on health. Stay-at-home orders should be the last considered restriction, given its detrimental consequences.
