A qualitative research, based on interview to draw findings in an inductive way, was conducted. Nine university students (N = 9) in a large mid-west university took part in a face- to face, semi-structured interviews using ten open-ended questions with respect to benefits of leisure time physical exercise. The interview on the basis of phenomenological research examined what the participants experienced with leisure time physical exercise in conjunction with stress coping and mental health. Meaningful units of themes were induced with 24 initially drawn themes. These themes were reduced to 8 comprehensive constituent themes: self-efficacy, positive emotion, mind and body, health-behaviors, self-esteem, leisure, problem-focused coping, and positive expectancy. These reduced themes were finally boiled down to 6 integrated themes: positive emotion, unity of mind and body, heightened self-esteem, leisure, problem-focused coping, and self-regulation of health behavior. This research may shed a light in illuminating potential mechanism of how regular physical exercise is conducive to enhanced health behavior as well as effective stress coping in university students in the context of leisure. In particular, this research appears to be meaningful in suggesting that regular leisure-time physical exercise can lead to an effective problem-focused coping through elicitation of positive emotion.展开更多

In view of these problems, it was proposed that construction of agricultural landscapes for the leisure agricultural industry parks should be combined with demonstration of cultures, holiday resort, and farming experience, and more efforts should be devoted in ecological maintenance, utilization of agricultural spaces, creation of cultural and leisure spaces. Moreover, to create agricultural eco-corridors, garden functions should be combined with the protection of ecosystems. Spatial connection of agricultural patches should be enhanced to form eco-corridor of the parks and meet the needs of production. And finally, concrete landscape construction techniques were put forward for the agricultural industry parks.展开更多

This study takes Shenyang, China as an example and analyzes the characteristics of residents’ leisure activities through questionnaires. On this basis, it uses point of interest data and mobile phone signaling data to identify various types of residential and leisure functional relationships, and uses spatial analysis and community detection to assess the distance characteristics, flow patterns, and community structure of residents’ leisure activities, so as to discuss the spatial structure of residents’ leisure activities in Shenyang. The results showed that: (1) in addition to leisure at home, Shenyang residents mainly went to shopping malls, supermarkets,and parks for leisure activities, and the proportions of residents of the two types of leisure activities were approximately equal;(2) the average distances that residents traveled for shopping and park leisure were near in the middle and far in the periphery, and the travel costs of peripheral residents for centrally located leisure were higher than those for residents in central areas;(3) the flow patterns of the residential-shopping and residential-park functional relationships displayed clustering mode characteristics, and Shenyang presented a significant monocentric structure;and (4) residents’ shopping activities were concentrated in the southern community, and walking in the park activities were concentrated in the western community. Residents’ leisure activities were characterized by centripetal agglomeration,which was prone to problems such as traffic congestion and big city diseases. The spatial expansion process in the city was characterized by obvious directional inheritance and path dependence, and the construction of sub-cities is needed to improve the related service facilities.展开更多

However, epidemiological studies specifically referred to LPTA in the last months of pregnancy are scarce. We evaluated the association between LPTA and the risk of both preterm delivery and small for gestational age (SGA) during the last three months of pregnancy in Italy. A nationwide case-control study was performed in nine Italian cities. A total of 299 preterm delivery, 364 SGA and 855 controls were enrolled in the study. A self-administered questionnaire was used to assess socio-demographic variables, medical and reproductive history, life-style habits and LTPA referred to the last three months of pregnancy. Univariate and multivariate regression analyses were performed in order to estimate Odds ratios and 95% CI. LTPA during the last three months of pregnancy decreases the risk of preterm delivery (adjusted OR = 0.56;95% CI 0.39 - 0.79). Among the different types of physical activity, walking, the most frequently referred activity, appears significantly protective against preterm delivery (adjusted OR = 0.53;95% CI 0.36 - 0.81). Moreover, a small protective effect of walking was evidenced against SGA (adjusted OR = 0.72;95% CI 0.51 - 1.00). In conclusion, a mild physical activity such as walking in the last three months of pregnancy seems to reduce the risk of preterm delivery and, at a lesser extent, of SGA, confirming the beneficial effects of physical activity along the whole pregnancy.展开更多

文摘The spatial characteristics of residents’ leisure activities not only reflect their demand for urban leisure space but also affect the urban spatial layout. This study takes Shenyang, China as an example and analyzes the characteristics of residents’ leisure activities through questionnaires. On this basis, it uses point of interest data and mobile phone signaling data to identify various types of residential and leisure functional relationships, and uses spatial analysis and community detection to assess the distance characteristics, flow patterns, and community structure of residents’ leisure activities, so as to discuss the spatial structure of residents’ leisure activities in Shenyang. The results showed that: (1) in addition to leisure at home, Shenyang residents mainly went to shopping malls, supermarkets,and parks for leisure activities, and the proportions of residents of the two types of leisure activities were approximately equal;(2) the average distances that residents traveled for shopping and park leisure were near in the middle and far in the periphery, and the travel costs of peripheral residents for centrally located leisure were higher than those for residents in central areas;(3) the flow patterns of the residential-shopping and residential-park functional relationships displayed clustering mode characteristics, and Shenyang presented a significant monocentric structure;and (4) residents’ shopping activities were concentrated in the southern community, and walking in the park activities were concentrated in the western community. Residents’ leisure activities were characterized by centripetal agglomeration,which was prone to problems such as traffic congestion and big city diseases. The spatial expansion process in the city was characterized by obvious directional inheritance and path dependence, and the construction of sub-cities is needed to improve the related service facilities.
文摘The association between Leisure Time Physical Activity (LTPA) during pregnancy and foetal outcomes has been extensively investigated. However, epidemiological studies specifically referred to LPTA in the last months of pregnancy are scarce. We evaluated the association between LPTA and the risk of both preterm delivery and small for gestational age (SGA) during the last three months of pregnancy in Italy. A nationwide case-control study was performed in nine Italian cities. A total of 299 preterm delivery, 364 SGA and 855 controls were enrolled in the study. A self-administered questionnaire was used to assess socio-demographic variables, medical and reproductive history, life-style habits and LTPA referred to the last three months of pregnancy. Univariate and multivariate regression analyses were performed in order to estimate Odds ratios and 95% CI. LTPA during the last three months of pregnancy decreases the risk of preterm delivery (adjusted OR = 0.56;95% CI 0.39 - 0.79). Among the different types of physical activity, walking, the most frequently referred activity, appears significantly protective against preterm delivery (adjusted OR = 0.53;95% CI 0.36 - 0.81). Moreover, a small protective effect of walking was evidenced against SGA (adjusted OR = 0.72;95% CI 0.51 - 1.00). In conclusion, a mild physical activity such as walking in the last three months of pregnancy seems to reduce the risk of preterm delivery and, at a lesser extent, of SGA, confirming the beneficial effects of physical activity along the whole pregnancy.

文摘With the income increase of elderly people in Beijing and the improvement of leisure facilities since 2000,the quality of elderly people leisure life in Beijing has obviously increased compared to ten years ago.According to the investigation and comparative analysis on more than 900 elderly people,who usually exercise in public parks in Beijing City,we have found out several new features of elderly people's outdoor recreation in Beijing:the increase of the leisure time,the expansion of leisure space,the individuation of interest and the diversification of consumption.The leisure life quality evaluation index system of urban elderly people can be built based on these analyses.In order to accommodate the development tendency of elderly people's demand for leisure diversification,we should strengthen the organization and management of elderly people's leisure activity in urban construction,and pay more attention to function complementation between communities and parks.
文摘Objective:To understand the current situation of undergraduates’flow experience in leisure and life satisfaction,and to explore the relationship between the two.Methods:A stratified random sampling method was used to select 781 undergraduates(377 males and 410 females)from 7 colleges and universities in Guangdong Province.They were investigated using the Flow Experience in Leisure Questionnaire(FELQ)and the Youth Life Satisfaction Scale(YLSS).Results:The total scores of FELQ and YLSS of the students in this group are(161.73±19.81)and(174.45±26.50).FELQ’s unity of knowledge and action,challenge and skill balance,concentration,grade ranking,family economic status are positively related to YLSS’life satisfaction(β=.227,.115,.098,.158,.082,P<.05);“Like to sleep during leisure”is negatively correlated with life satisfaction of YLSS(β=-.097,P<.05);FELQ’s unity of knowledge and action,concentration,grade ranking and family economic status are positively related to YLSS’s self-satisfaction(β=.286,.126,.194,.096,P<.01);“Like to sleep during leisure”is negatively correlated with YLSS’s self-satisfaction(β=-.091,P<.01);FELQ’s unity of knowledge and action,challenge and skill balance,father’s occupation,“like self-study in leisure”are positively related to YLSS’environmental satisfaction(β=.198,.131,.075,.073,P<.05);“Like to sleep during leisure”,gender and YLSS environment satisfaction negatively correlated(β=-.094,-.091,P<.01).Conclusion:Flow experience in leisure,types of leisure activities,gender,grade ranking and family factors(family economic status and father’s occupation)may be related factors for the development of college students’life satisfaction.
