Bone Vascularization

Physical activity is widely recognized as a biotherapy by WHO in the fight and prevention of bone diseases such as osteoporosis. It reduces the risk of disabling fractures associated with many comorbidities, and whose repair is a major public health and economic issue. Bone tissue is a dynamic supportive tissue that reshapes itself according to the mechanical stresses to which it is exposed. Physical exercise is recognized as a key factor for bone health. However, the effects of exercise on bone quality depend on exercise protocols, duration, intensity, and frequency. Today, the effects of different exercise modalities on capillary bone vascularization, bone blood flow, and bone angiogenesis remain poorly understood and unclear. As vascularization is an integral part of bone repair process, the analysis of the preventive and/or curative effects of physical exercise is currently very undeveloped. Angiogenesis–osteogenesis coupling may constitute a new way for understanding the role of physical activity, especially in fracturing or in the integration of bone biomaterials. Thus, this review aimed to clarify the link between physical activities, vascularization, and bone repair.

Background: To prevent and fight the increase of daily sedentary time and to promote and stimulate the positive effects of physical activity and exercise on health, both traditional interventions and new strategies are important for breast cancer survivors (BCS). The research goal was to compare the effects of weekly personal feedback, based on objectively measured physical activity, on the trends of both daily sedentary time and on the physical activity of BCS (E− group) with those of an intervention also including online supervised physical exercise sessions (E+ group), during the Italy COVID-19 lockdown. Methods: The Italian COVID-19 emergency allowed the possibility to also observe the effects of social and personal limitations. A total of 51 BCS were studied over an 18-week period and had an objective registration of day-to-day sedentary time, physical activity, and sleep. Both subsamples received weekly or fortnight personal feedback. Data were analysed considering four key periods, according to the COVID-19 emergency steps. Results: Statistical analysis showed an additive effect for sedentary time and a multiplicative effect both for light-to vigorous and light-intensity physical activities. The E− group had a high overall sedentary time and a different trend of light-to vigorous and light-intensity physical activities, with a reduction from the 1st to the 2nd periods (national and personal restrictions), showing a significant rise just at the end of the national restrictions. Conclusions: The use of an activity tracker and its accompanying app, with the reception of weekly tailored advice and supervised online physical exercise sessions, can elicit proper physical activity recomposition in BCS in the COVID-19 era.

Along with environmental pollution, urban planning has been connected to public health. The research indicates that the quality of built environments plays an important role in reducing mental disorders and overall health. The structure and shape of the city are considered as one of the factors influencing happiness and health in urban communities and the type of the daily activities of citizens. The aim of this study was to promote physical activity in the main structure of the city via urban design in a way that the main form and morphology of the city can encourage citizens to move around and have physical activity within the city. Functional, physical, cultural-social, and perceptual-visual features are regarded as the most important and effective criteria in increasing physical activities in urban spaces, based on literature review. The environmental quality of urban spaces and their role in the physical activities of citizens in urban spaces were assessed by using the questionnaire tool and analytical network process (ANP) of structural equation modeling. Further, the space syntax method was utilized to evaluate the role of the spatial integration of urban spaces on improving physical activities. Based on the results, consideration of functional diversity, spatial flexibility and integration, security, and the aesthetic and visual quality of urban spaces plays an important role in improving the physical health of citizens in urban spaces. Further, more physical activities, including motivation for walking and the sense of public health and happiness, were observed in the streets having higher linkage and space syntax indexes with their surrounding texture.

The aim of this paper is to present the significance of the recreational space in Poznań for the physical activity of the city’s residents. The factors considered in the study were the following: the range of possibilities for engagement in paid-for and free-of-charge physical activities, the perceived availability of green areas, the favourite places for physical activity and the role of the neighbourhood and flows in this aspect. The paper presents the results of a survey conducted among 1,244 inhabitants of Poznań in 2017. The respondents positively assessed the possibilities of undertaking physical activity in the context of the city/ space offer. The access to various sports was rated positive, among it the paid activities offered were rated higher than free-of-charge ones. The availability of green areas near the place of residence was assessed as good. Two locations, Cytadela Park and Lake Malta with the surrounding green areas, were the most popular for pursuing physical activity.

Lack of physical exercise is considered an important risk factor for chronic diseases. On the contrary, physical exercise reduces the morbidity rates of obesity, diabetes, bone disease, and hypertension. In order to gain novel molecular and cellular clues, we analyzed the effects of physical exercise on differentiation of mesenchymal circulating progenitor cells (M-CPCs) obtained from runners. We also investigated autophagy and telomerase-related gene expression to evaluate the involvement of specific cellular functions in the differentiation process. We performed cellular and molecular analyses in M-CPCs, obtained by a depletion method, of 22 subjects before (PRE RUN) and after (POST RUN) a half marathon performance. In order to prove our findings, we performed also in vitro analyses by testing the effects of runners’ sera on a human bone marrow-derived mesenchymal stem (hBM-MSC) cell line. PCR array analyses of PRE RUN versus POST RUN M-CPC total RNAs put in evidence several genes which appeared to be modulated by physical activity. Our results showed that physical exercise promotes differentiation. Osteogenesis-related genes as RUNX2, MSX1, and SPP1 appeared to be upregulated after the run; data showed also increased levels of BMP2 and BMP6 expressions. SOX9, COL2A1, and COMP gene enhanced expression suggested the induction of chondrocytic differentiation as well. The expression of telomerase-associated genes and of two autophagy-related genes, ATG3 and ULK1, was also affected and correlated positively with MSC differentiation. These data highlight an attractive cellular scenario, outlining the role of autophagic response to physical exercise and suggesting new insights into the benefits of physical exercise in counteracting chronic degenerative conditions.

Perceived Neighborhood Safety

The aim of study was to investigate the effects of parents' perceptions of neighborhood safety on outdoor physical activities of preschool children. This was investigated based on a moderating role of a child's gender and parents' age. The results showed that the association of parents’ perceptions of neighborhood safety on outdoor physical activities of children depended of the child’s sex and the parents’ age. Boys whose parents were younger and who positively assessed the neighborhood safety were more inclined to outdoor physical activities. Female children whose parents were below the average age the perceived neighborhood safety hindered frequent outdoor playing. The paper discusses practical implications of the obtained results and recommendations for future research.

Mortality Benefit

Eighty observational association studies and several controlled trials provide strong evidence that exercise, done in appropriate amounts and with appropriate techniques, can dramatically enhance well-being and decrease morbidity and mortality. This chapter summarizes the available evidence so that healthcare providers can write rational prescriptions for physical activity for patients that allow minimal activity for maximum health benefit. In brief, doing four physical activities weekly—(1) any kind, (2) strength building, (3) bone strengthening (jumping), and (4) stamina building—and avoiding prolonged (> 1 hr) inactivity by walking for two minutes every hour—provides maximal morbidity and mortality benefit.

This article introduces the special issue on ‘Understanding Blue Spaces’ which examines relationships between blue spaces, sport, physical activity, and wellbeing. The articles progress conversations across humanities, social sciences and inter-disciplinary areas of research on diverse sporting practices, that span local to trans-national contexts. This collection offers new insights into politics, possibilities, and problems of the role of blue spaces in our wellbeing—individually, socially, and ecologically. In addition to outlining the 10 articles in the SI, which include ocean swimming, surfing, sailing/yachting, and waka ama paddling, we contextualize this work, discussing key thematic areas both across these papers, and in the wider interdisciplinary body of work on blue spaces, wellbeing, and sport. Specifically, we outline the role of physical activities and leisure practices in how we access, understand, experience, and develop relationships to seas and oceans, as well as to self, places and communities of human and non-human others. We also discuss the ways in which particular bodies, individuals, and communities (human and more-than-human) are marginalized or excluded, and the need for understanding concepts such as wellbeing, place, and self beyond dominant European traditions. This SI highlights how localised experiences of blue spaces can be, while emphasising the need to recognize diverse cultural, economic, geographic, sociodemographic, and political factors that contribute to a disconnect with, or exclusion from blue spaces, impacting who can use blue spaces, how they can be used, how they can be researched, and how power is reproduced and contested.

Physical education is a course taught in school that focuses on developing physical fitness and the ability to perform and enjoy day to day physical activities with ease. Kids also develop skills necessary to participate in a wide range of activities such as cricket,basketball or swimming.Regular physical education classes prepare kids to be physically and mentally active, fit and healthy. Physical education helps students develop physical skills and confidence. They would be expected to journal about how they feel during the process and reflect on how these changes affect performance and mood.Physical education also helps students develop social skills.For example,team sports help them learn to respect others, contribute to a team goal, and socialize as a productive member of a team.This Study is to prove that there is a direct correlation between physical activity and the overall development of the child. It is to prove that there is a systematic, scientific improvement in the cognitive, emotional, social skills and also improvement in Health when physical education is implemented in the Childs day to day programme.The curriculum of physical education possesses a body of knowledge which is basic to health and fitness that leads to a fine living. It has a core of activity skill and technique in its content.We are living in a world layered in technology and convince.Physical Education is so important for our future because it is one of the best natural and pure means we have to promote and foster play and purpose for our children. Children need it more than we know and technology is slowly eating away at something we might never get back. Physical Education's purpose is to preserve the foundational history of health, fitness, and to allow our youth to develop into people with strong intrapersonal skills,core values,and respect and understanding of a healthy mind/body connection.With physical education being a crucial need especially for children, it should be implemented in all the educational organization.To make sure that it is implemented,it has to be a part of the curriculum.Certain norms have to be implemented to make sure PE is a part of the academic curriculum.Regular assessments will be helpful to work on the improvement of the Childs physical as well as overall development
