Background: The problem of an inadequate level of physical activity (PA) is important in the context of its relationship with the quality of life (QoL) of pregnant women. The aim of this study was to analyze the relationships between PA and QoL among pregnant women. Methods: The study analyzed 346 questionnaires filled in by pregnant women (157 in the second trimester and 189 in the third). The tool used for assessment of PA was the Pregnancy Physical Activity Questionnaire-Polish version (PPAQ-PL). The quality of life (QoL) was assessed by the World Health Organization Quality of Life Questionnaire-short form (WHOQoL-Bref). The results obtained from the PPAQ-PL and WHOQoL-Bref questionnaires for women in the second and third trimesters of pregnancy and intergroup differences were analyzed. Results: There was a significant correlation in the group of women in the second trimester of pregnancy between quality of life in the physical health domain and the intensity and type of physical activity. The women who rated their quality of life higher in this domain declared higher energy expenditures (EE) associated with vigorous activity (R = 0.159, p ≤ 0.05), as well as with occupational activity (R = 0.166; p ≤ 0.05) and sport/exercise activity (R = 0.187; p ≤ 0.05). In women in the third trimester, higher EE related to sport/exercise activity coincided with higher assessments of the overall quality of life (R = 0.149, p ≤ 0.05) and general health (R = 0.170, p ≤ 0.05). In the case of the psychological domain (R = 0.161, p ≤ 0.05) and social relationship domain (R = 0.188; p ≤ 0.05) of QoL, positive correlations occurred with EE related to vigorous activity. In contrast, high assessment of physical health domain coincided with higher EE related to occupational activity (R = 0.174; p ≤ 0.05). Conclusions: Our study makes an important contribution to knowledge concerning the correlations between PA and QoL in pregnancy. The results suggest the need for improvement in prenatal care and promotion of PA programs for pregnant women.

Background: Physical activity (PA) surveillance, policy, and research efforts need to be periodically appraised to gain insight into national and global capacities for PA promotion. The aim of this paper was to assess the status and trends in PA surveillance, policy, and research in 164 countries. Methods: We used data from the Global Observatory for Physical Activity (GoPA!) 2015 and 2020 surveys. Comprehensive searches were performed for each country to determine the level of development of their PA surveillance, policy, and research, and the findings were verified by the GoPA! Country Contacts. Trends were analyzed based on the data available for both survey years. Results: The global 5-year progress in all 3 indicators was modest, with most countries either improving or staying at the same level. PA surveillance, policy, and research improved or remained at a high level in 48.1%, 40.6%, and 42.1% of the countries, respectively. PA surveillance, policy, and research scores decreased or remained at a low level in 8.3%, 15.8%, and 28.6% of the countries, respectively. The highest capacity for PA promotion was found in Europe, the lowest in Africa and low- and lower-middle-income countries. Although a large percentage of the world’s population benefit from at least some PA policy, surveillance, and research efforts in their countries, 49.6 million people are without PA surveillance, 629.4 million people are without PA policy, and 108.7 million live in countries without any PA research output. A total of 6.3 billion people or 88.2% of the world’s population live in countries where PA promotion capacity should be significantly improved. Conclusion: Despite PA is essential for health, there are large inequalities between countries and world regions in their capacity to promote PA. Coordinated efforts are needed to reduce the inequalities and improve the global capacity for PA promotion.

We make use of a nation-wide survey Bicycle use in everyday commuting (n = 1159 + 300) to identify the motivations and barriers to commuting by bicycle in Poland. Only 10.9% of adult Poles commute this way, and 7.6% do so frequently. Bicycle is also rarely considered a dominant mode of transport. In many cases, it is the choice of the worse-off individuals (poorly educated, less wealthy, rural areas dwellers etc.). Based on factor and cluster analysis of declared motivations, we identified 4 segments of commuters: conscious, forced, pro-health, and lifestyle cyclists. The first group rates existing road infrastructure, cycling facilities and safety issues differently than non-cyclists. The availability of basic facilities (parking place, cloakrooms, showers) is declared significantly more often by cyclists, while car drivers’ behaviour on the roads is evaluated more negatively, comparing to non-cyclists.

The assessment of quality of life (QoL) among elderly people is of great importance when preparing health care programmes for this social group. Many researchers indicate that poor health is less frequently observed in senior citizens who display levels of physical activity (PA) prescribed by WHO. The aim of the study was to investigate the relationship between the level of PA among students of the University of the Third Age (U3A) and their self-assessment concerning their QoL. The research sample consisted of 131 students from three U3A in West Pomeranian Voivodeship in Poland. PA was assessed with the aid of a short Polish version of the International Physical Activity Questionnaire (IPAQ). The assessment of QoL was conducted with the use of a Polish version of the WHO Quality of Life--BREF instrument (WHOQOL-BREF). The present study has shown that highly active U3A students declare high QoL in the psychological and social domains more often than other respondents. The level of PA recommended by WHO has a positive impact on the perceived QoL. Possible differences are visible mostly in the assessment of different domains of life in relation to the presented levels of PA.

Background: The article is devoted to an analysis of leisure-time (amateur) table tennis in Poland, its practitioners and the regularities of their activity. Methods: The study examined 12,406 persons in 4689 households (representative for the population). We used binary logistic regression and descriptive statistics in order to identify the patterns and determinants of table-tennis practice in Poland. Results: Table tennis is practised by 2.8% of population, and by 6.6% of physically active Poles. Among adults it is predominantly an occasional recreational game, not performed as a sport per se. Among children, it is often the part of physical education (PE) classes. Statistically significant predictors of contact with table tennis are: gender, age, income, place of residence, children in the household and being a student. Conclusions: Due to the undeniable benefits of table tennis (health, pleasure, personal and social development), the sport is recommended for use as a tool in increasing the (overall low) physical activity of Poles. Its popularization requires promotion in the media (as a health-oriented activity) and using various channels, including public places, the workplace (as part of corporate social responsibility) and physical education classes at school.

To assess the physical activity of working residents of Warsaw aged 20-69 years, as well as to identify the socio-demographic factors associated with their levels of physical activity. The study involved 2,544 working residents of Warsaw aged 20-69 years. The short version of the IPAQ was applied and four physical activity levels (insufficient, sufficient, augmented, high) were distinguished. The relationships between physical activity and gender, age, BMI, education, economic and martial status as well as participation in recreation were determined. High levels of physical activity were reached by 8% of respondents, 22% achieved augmented level, 32% were sufficiently and 32% insufficiently active. Out of 2544 studied subjects, 6% declared complete sedentariness. Females were, as compared to males, more frequently (p<0.05) insufficiently active (35.9 vs. 31.9%). In obese and overweight subjects insufficient physical activity predominated (42.9 and 36.2%, respectively) and was significantly more frequent than in subjects with normal BMI (31.0%). Moreover, the subjects living in partner relationships were significantly (p<0.05) more frequently insufficiently active than those staying single (36.3 vs. 30.3%). Respondents who declared regular participation in leisure activities were less frequently insufficiently active (20.0%) and more frequently met the criteria of sufficient (37.6%), augmented (28.0%) or high (14.4%) level of physical activity. No significant effects were found with respect to education of respondents. Prophylactic schedules associated with the improvement of physical activity level should be addressed particularly to females, people taking up recreation occasionally or to those not involved in recreation at all, living in partner relationships, youngest (21-30 years), in obese and overweight and in the lowest economic category.
