Social isolation and physical inactivity in older US adults: Results from the Third National Health and Nutrition Examination Survey

Abstract

Physical inactivity is a risk factor for cardiovascular and other chronic diseases. It has been shown that both physical inactivity and social isolation increase with age, and that these factors are detrimental to physical and mental well-being. The purpose of the present study was to examine the relationship between physical inactivity and social isolation in older US adults. Using data from a nationally representative cross-sectional survey, the Third National Health and Nutrition Examination Survey, 1988–1994, we assessed the age- and race-specific prevalence of no leisure-time physical activity in relation to various forms of social interaction. The prevalence of no leisure-time physical activity increases with age in both men and women. In non-Hispanic whites, non-Hispanic blacks, and Mexican Americans, the prevalence of no leisure-time physical activity is increased in older US adults who are socially isolated. Social isolation is related to physical inactivity among persons 60 years and older. Longitudinal and intervention studies are needed to establish whether increased social support translates to a more active population of older adults.     

‘You don’t want to stand out as the bigger one’: exploring how PE and school sport participation is influenced by pupils and their peers

Background: Population health concerns related to physical inactivity and obesity appear in policy documents, government campaigns and popular media across western societies. Children and young people have been targeted for physical activity promotion and schools have been positioned as sites for intervention. In particular, Physical Education and school sport (PESS) has been framed as a key part of the solution. While some interventionist programmes in schools have reported positive outcomes, they have also been criticised for stigmatising fatness, contributing to a culture of surveillance and fuelling body image anxieties. Despite ongoing work to ameliorate these critical issues by addressing physical activity promotion discourses, curricula and teaching practices many of the same challenges persist. In seeking alternative explanations (and solutions) this paper shifts attention to exploring the role of pupils and their peers.

Purpose: While the critical literature on health and physical education has been illuminating, few studies explore the role of pupils and their peers. Further research is necessary to understand how school peers contribute to pupils’ engagement with PESS. This paper, therefore, draws on Bourdieu’s notion of physical capital and seeks to understand how pupils’ physical activity is influenced by lived-body experiences in school spaces.

The study: Data were produced from a 6-month bricolage-based study with pupils (N?=?29, aged 13–14) across four diverse school settings in England. Multiple qualitative methods were deployed to enhance methodological rigour with what is often a challenging age group for research. Data were interpreted and theorised using the concept of physical capital.

Findings: Pupils themselves play a significant part in establishing the physical body as a symbol of power and status in school settings. Participants understood the health risks of being both underweight and obese, but they regarded obesity as being more problematic because of the immediate social risks of ‘standing out as the bigger one’. Following this rationale, participants sought to accumulate physical capital through engaging in exercise as a purposeful calorie-burning activity intended to avoid the pity, abnormality and derision which is expected to be directed towards overweight pupils. Furthermore, during PESS in clear view of peers, distinctions between pupils’ physical capital could be made by recognising differences in sporting skill. In this context, physical capital mediated engagement in PESS in various ways.

Conclusion: This study has revealed that peers play a significant part in constructing the lived-body experiences of young people. In order to address the criticisms raised about some school-based health promotion interventions, it is crucial to attend to pupils’ relationships with peers as well as addressing policies, curricula and teaching practices. Being sensitive to peer relationships and their understanding of health may help teachers and health promoters decide how to manage the spaces where PESS takes place.     

Physical inactivity and muscle oxidative capacity in humans

Abstract

Physical inactivity is associated with a high prevalence of type 2 diabetes and is an independent predictor of mortality. It is possible that the detrimental effects of physical inactivity are mediated through a lack of adequate muscle oxidative capacity. This short review will cover the present literature on the effects of different models of inactivity on muscle oxidative capacity in humans. Effects of physical inactivity include decreased mitochondrial content, decreased activity of oxidative enzymes, changes in markers of oxidative stress and a decreased expression of genes and contents of proteins related to oxidative phosphorylation. With such a substantial down-regulation, it is likely that a range of adenosine triphosphate (ATP)-dependent pathways such as calcium signalling, respiratory capacity and apoptosis are affected by physical inactivity. However, this has not been investigated in humans, and further studies are required to substantiate this hypothesis, which could expand our knowledge of the potential link between lifestyle-related diseases and muscle oxidative capacity. Furthermore, even though a large body of literature reports the effect of physical training on muscle oxidative capacity, the adaptations that occur with physical inactivity may not always be opposite to that of physical training. Thus, it is concluded that studies on the effect of physical inactivity per se on muscle oxidative capacity in functional human skeletal muscle are warranted.     

Does school physical education really contribute to accelerometer-measured daily physical activity and non sedentary behaviour in high school students?

Physical education has been highlighted as an important environment for physical activity promotion, however, to our knowledge there are no previous studies examining the contribution of physical education to daily accelerometer-measured physical activity and non sedentary behaviour. The purpose was to compare the accelerometer-measured physical activity and sedentary behaviour between physical education, non-physical education and weekend days in adolescents. Of the 394 students from a Spanish high school that were invited to participate, 158 students (83 boys and 75 girls) aged 13–16 years were analyzed (wear time ≥ 600 min). Participants’ physical activity and sedentary behaviour were objectively-measured by GT3X+ accelerometers during physical education (one session), non-physical education and weekend days. Results indicated that overall adolescents had statistically significant greater physical activity levels and lower values of sedentary behaviour on physical education days than on non-physical education and weekend days (e.g., moderate-to-vigorous physical activity = 71, 54 and 57 min; sedentary = 710, 740 and 723 min) (p < 0.05). Physical education contributes significantly to reducing students’ daily physical inactivity and sedentary behaviour. Increasing the number of physical education classes seems to be an effective strategy to reduce the high current prevalence of physical inactivity and sedentary behaviour in adolescence.     

Factors Related to Rural Young Adolescents' Participation in Outdoor,Noncompetitive Physical Activity

Purpose: Young adolescents who have little interest in participating in competitive team sports are at an increased risk for physical inactivity. Noncompetitive outdoor physical activity can provide young adolescents with increased opportunities to participate in physical activities that appeal to them and have positive health effects. The purpose of this study was to examine factors related to rural young adolescents' participation in noncompetitive outdoor physical activity to inform intervention design. Method: Young adolescents aged 10 to 14 years old (N = 1,032) from 1 rural county completed a self-administered questionnaire assessing constructs from self-determination theory (SDT) and the theory of planned behavior (TPB) related to noncompetitive outdoor physical activity. Structural equation modeling was used to examine an integrated conceptual model of hypothesized relationships among constructs. Results: The hypothesized conceptual model provided a good fit to the data with greater perceptions of autonomy support and self-determined motivation having statistically significant positive indirect effects on participation in noncompetitive outdoor physical activity mediated by the constructs of the TPB. All direct paths in the model were statistically significant; however, the direct effect of attitudes on intention was weak (.08) and self-determined motivation had no indirect effect on intention through attitudes (.03). Conclusions: Constructs of SDT and TPB should be accounted for by interventions targeting noncompetitive outdoor physical activity among young adolescents. More research is needed to determine young adolescents' preferences for noncompetitive and competitive physical activity and the potential influence that noncompetitive outdoor physical activity may have on total daily physical activity.     

Higher screen time is associated with overweight,poor dietary habits and physical inactivity in Brazilian adolescents,mainly among girls

Objectives: To analyse the associations between high screen time and overweight, poor dietary habits and physical activity in adolescents according to sex. Methods: The study comprised 515 boys and 716 girls aged 14–17 years from Londrina, Brazil. Nutritional status (normal weight or overweight/obese) was assessed by calculating the body mass index. Eating habits and time spent in physical activity were reported using a questionnaire. The measurement of screen time considered the time spent watching television, using a computer and playing video games during a normal week. Associations between high screen time and dependent variables (nutritional status, eating habits and physical activity levels) were assessed by binary logistic regression, adjusted for sociodemographic and lifestyle variables. Results: Most adolescents (93.8% of boys and 87.2% of girls) spent more than 2 hours per day in screen-time activities. After adjustments, an increasing trend in the prevalence of overweight and physical inactivity with increasing time spent on screen activities was observed for both sexes. Screen times of >4 hours/day compared with <2 hours/day were associated with physical inactivity, low consumption of vegetables and high consumption of sweets only in girls and the consumption of soft drinks in both sexes. Conclusions: The frequency of overweight and physical inactivity increased with increasing screen time in a trending manner and independently of the main confounders. The relationship between high screen time and poor eating habits was particularly relevant for adolescent girls.     

Weekday and weekend patterns of physical activity and sedentary time among Liverpool and Madrid youth

Abstract

Levels of physical inactivity and sedentary behaviour among English and Spanish youth are high and vary within different regions of each country. Little though is known about these during specific periods of the day. The purpose of this study was to describe physical activity (PA) and sedentary time during segments of the day and week, and compare these critical contexts between youth in the Liverpool and Madrid areas of England and Spain, respectively. PA was objectively assessed in 235 Liverpool- and 241 Madrid youth (aged 10–14 years) who wore accelerometers for seven consecutive days. Minutes of sedentary time, moderate PA, vigorous PA and moderate-to-vigorous physical activity (MVPA) were calculated for weekdays, weekend days, school time, non-school time and after-school. Between-country differences were analysed using analysis of covariance (ANCOVA). Madrid youth spent significantly more time in sedentary activities than their Liverpool counterparts. Madrid youth engaged in more minutes of moderate intensity physical activity (MPA) than Liverpool youth during weekdays, school time and non-school time (P<0.01). Liverpool children recorded more time in vigorous physical activity (VPA) than Madrid peers during week days and weekend days (P<0.01) and during school time and after-school periods (P <0.01). The MVPA was significantly higher among Madrid youth during non-school time (P<0.01). Around 25% of all youth achieved recommended levels of MVPA. Low levels of MVPA and systematic differences in sedentary time, MPA and VPA exist between Liverpool and Madrid youth. Interventions targeted at the least-active children during weekends, after-school and non-school periods within the cultural contexts common to each city are required.     

Physical activity lowers the risk for acute respiratory infections: Time for recognition

Physical inactivity is a well-established risk factor for chronic diseases, such as cardiovascular disease, cancer, and diabetes mellitus. There is a growing awareness that physical inactivity should also be regarded as a risk factor for acute respiratory infections (ARIs). ARIs, such as the common cold, influenza, pneumonia, and coronavirus disease 2019 (COVID-19), are among the most pervasive diseases on earth and cause widespread morbidity and mortality. Evidence in support of the linkage between ARIs and physical inactivity has been strengthened during the COVID-19 pandemic because of increased scientific scrutiny. Large-scale studies have consistently reported that the risk for severe COVID-19 outcomes is elevated in cohorts with low physical activity and/or physical fitness, even after adjusting for other risk factors. The lowered risk for severe COVID-19 and other ARIs in physically active groups is attributed to exercise-induced immunoprotective effects, including enhanced surveillance of key immune cells and reduced chronic inflammation. Scientific consensus groups, including those who submitted the Physical Activity Guidelines for Americans, have not yet given this area of research the respect that is due. It is time to add “reduced risk for ARIs” to the “Exercise is Medicine” list of physical activity-related health benefits.     

Touching the didactic contract—a student perspective on intergenerational touch in PE

A growing anxiety around intergenerational touch in educational settings has both emerged and increased in recent years. Previous research reveals that Physical Education (PE) teachers have become more cautious in their approaches to students and they avoid physical contact or other behavior that could be regarded as suspicious [Fletcher, 2013. Touching practice and physical education: Deconstruction of a contemporary moral panic. Sport, Education and Society, 18(5), 694–709. doi:10.1080/13573322.2013.774272; Öhman, 2016. Losing touch—teachers’ self-regulation in physical education. European Physical Education Review, 1–14. doi:10.1177/1356336X15622159; Piper, Garratt, & Taylor, 2013. Child abuse, child protection and defensive ‘touch’ in PE teaching and sports coaching. Sport, Education and Society, 18(5), 583–598. doi:10.1080/13573322.2012.735653]. Some also feel anxious about how physical contact might be perceived by the students. The purpose of this article is to investigate physical contact between teachers and students in PE from a student perspective. This is understood through the didactic contract. For this purpose, focus group interviews using photo elicitation have been conducted with upper secondary school students in Sweden. One of the major findings is that intergenerational touch is purpose bound, that is, physical contact is considered relevant if the teacher has a good intention with using physical contact. The main agreements regarding physical contact as purpose bound are the practical learning and emotional aspects, such as learning new techniques, preventing injury, closeness and encouragement. The didactic contract is in these aspects stable and obvious. The main disagreements are when teachers interfere when the students want to feel capable or when teachers interfere when physical contact is not required in the activity. In these aspects the didactic contract is easily breached. It is also evident that personal preference has an impact on how physical contact is perceived. In conclusion, we can say that physical contact in PE is not a question of appropriate or inappropriate touch in general, but rather an agreement between the people involved about what is expected. Consequently, we should not ban intergenerational touch, but rather focus on teachers’ abilities to deal professionally with the didactic contract regarding physical contact.     

Mechanics of Batting: Effect of Stride Technique on Ground Reaction Forces and Bat Velocities

The benefits associated with being physically active are well documented, but a significant proportion of the population is insufficiently active. Physical inactivity is a major health risk factor in our society, and physical education programs are consistently identified as a means to address this concern. The purpose of this article is to use the social-ecological model as a framework to examine ways in which physical education programs can play an important role in promoting physical activity. Policies that require time allocations and resources for physical education and physical activity in schools and community designs that provide infrastructure that makes being physically active accessible and convenient are important factors in making schools and communities healthier spaces. It is clear, however, that policies alone are not sufficient to address concerns about physical inactivity. We must consider individual factors that influence decisions to be physically active in efforts to engage children in physical education programs that promote active lifestyles. The learning climate that teachers create determines what students do and learn in physical education classes. Ensuring that students see value in the content presented and structuring classes so that students believe they can experience success when they exert effort are key elements in an effective motivational climate. Efforts to address public health concerns about physical inactivity require a comprehensive approach including quality physical education. It is critical that kinesiology professionals emerge as leaders in these efforts to place physical education programs at the center of promoting children's physical activity.     

Diet and Physical Activity Patterns of Obese and Nonobese Elementary School Children

Abstract

The caloric intake and physical activity patterns of 50 fifth grade students were studied to determine the relative contributions of diet and physical inactivity in the development of obesity. On the basis of tricep skinfold measurements, the subjects were divided into four groups or levels of obesity. Seven-day diet recall records were then obtained with the cooperation of the children's parents. Activity patterns were studied by filming the subjects during games of high and low organization and during free play. Indexes of the duration and intensity of activity were derived from the film analysis. The caloric intake and physical activity patterns of the four groups were compared by the Duncan Multiple Range Test. Using the combined scores for all groups, correlation coefficients were computed to determine the relationship between (1) skinfold measures and total caloric intake, (2) skinfold measures and activity patterns, and (3) total caloric intake and activity patterns. The relative inactivity of the obese children and the relatively similar diets of all children regardless of body fat, as well as the significant negative relationship between activity indexes and body fat tended to support the contention that inactivity may be as important or more important than excessive caloric intake in the development and maintenance of childhood obesity.     

Get moving! A comparison of ideas about body,health and physical activity in materials produced for health education in the Danish Primary School

In the debate over health, one political message has become more and more dominant in western societies over the past decade: Get moving! The logic seems to be that physical activity per se equals better health and that the more physical activity, the better one's health. This logic has, among other things, induced an increased political focus on educational settings and physical education (PE) as a central place for promoting health by increasing physical activity. Today PE is often explicitly identified with health in contemporary school curricula, and this means that PE teachers unavoidably encounter contemporary perceptions of health and physical activity in their professional practice. Taking as its starting point four different teaching resources produced for health education in the Danish Primary School, this article presents four different health cultures and their recommendations for physical activity as a health-promoting practice. The aim is to challenge current perceptions of health and the related recommendations for physical activity in providing a springboard for health communicators and PE teachers to reflect on the health cultures they encounter and maybe to consider how these aligns their own preferred health culture.     

Commentary on research into learning in physical education: towards a mature field of knowledge

In this commentary, I consider each of the papers in this special issue in regard to their contribution to a debate on the nature of learning in physical education (PE). I also discuss how we might take this aspiration further by moving beyond a ‘mere’ debate over learning theories to a knowledge building process in which knowledge claims are ‘tested’ against their compatibility (or non-compatibility) with other ‘knowings’. In this regard, I introduce the idea of vertical integration or compatibility as a consideration for building a more mature field of study of learning in PE.     

‘It doesn't matter how they move really,as long as they move.’ Physical education teachers on developing their students’ movement capabilities

Background: Movement is key in physical education, but the educational value of moving is sometimes obscure. In Sweden, recent school reforms have endeavoured to introduce social constructionist concepts of knowledge and learning into physical education, where the movement capabilities of students are in focus. However, this means introducing a host of new and untested concepts to the physical education teacher community.

Purpose. The purpose of this article is to explore how Swedish physical education teachers reason about helping their students develop movement capability.

Participants, setting and research design. The data are taken from a research project conducted in eight Swedish secondary schools called ‘Physical education and health – a subject for learning?’ in which students and teachers were interviewed and physical education lessons were video-recorded. This article draws on data from interviews with the eight participating teachers, five men and three women. The teachers were interviewed partly using a stimulated recall technique where the teachers were asked to comment on video clips from physical education lessons where they themselves act as teachers.

Data analysis. A discourse analysis was conducted with a particular focus on the ensemble of more or less regulated, deliberate and finalised ways of doing things that characterise the eight teachers’ approach to helping the students develop their movement capabilities.

Findings. The interviews indicate that an activation discourse (‘trying out’ and ‘being active’) dominates the teachers’ ways of reasoning about their task (a focal discourse). When the teachers were specifically asked about how they can help the students improve their movement capacities, a sport discourse (a referential discourse) was expressed. This discourse, which is based on the standards of excellence of different sports, conditions what the teachers see as (im)possible to do due to time limitations and a wish not to criticise the students publicly. The mandated holistic social constructionist discourse about knowledge and learning becomes obscure (an intruder discourse) in the sense that the teachers interpret it from the point of view of a dualist discourse, where ‘knowledge’ (theory) and ‘skill’ (practice) are divided.

Conclusions. Physical education teachers recoil from the task of developing the students’ movement capabilities due to certain conditions of impossibility related to the discursive terrain they are moving in. The teachers see as their primary objective the promotion of physical activity – now and in the future; they conceptualise movement capability in such a way that emphasising the latter would jeopardise their possibilities of realising the primary objective. Should the aim be to reinforce the social constructionist national curriculum, where capability to move is suggested to be an attempt at formulating a concept of knowledge that includes both propositional and procedural aspects and which is not based on the standards of excellence of either sport techniques or motor ability, then teachers will need support to interpret the national curriculum from a social constructionist perspective. Further, alternative standards of excellence as well as a vocabulary for articulating these will have to be developed.     

Towards an activist approach to research and advocacy for girls and physical education

Background: Much research and practice in the field of physical activity and physical education for girls has been trapped in a reproductive cycle of telling the ‘same old story’ as if it is news over and over again, since at least the 1980s. A thread running through this narrative is that despite all of this research and related interventions, we have yet to find the ‘solution’ to the ‘problem’ of girls and physical education. As a result, little progress appears to have been made in terms of changing things for the better for the majority of girls.

Purpose: We offer an activist approach to work with girls in physical education as one possible means of breaking the reproductive cycle of research and media reporting that we suggest has worked against improving the situation for girls. We take a pragmatist stance to ask ‘can we make the situation for girls better than it is currently?’ and ‘how might we go about this task?’ We propose an activist approach not as ‘the solution’ to the ‘problem’ of girls in physical education, but as one worthy of testing in practice.

Process: We begin by outlining the broad features of an activist approach to working with girls in physical education. We then overview the findings of a growing body of activist studies in physical education and identify four critical elements that we believe need to be present in order to assist girls to identify, name and negotiate barriers to their engagements with physical education and their participation in physically active lifestyles. We highlight one example of an activist study that shows how the four critical elements interact in their work with girls.

Discussion: We argue for the need for a consensus around improving the current situation of girls in physical education, for a scaling up of this activist work as it is tested in practice, and for the coincidental development of a pedagogical model for working with girls in physical education.     

Biological maturity and primary school children's physical activity: Influence of different physical activity assessment instruments

Abstract

Biological maturation may attenuate hypothesized sex differences in children's physical activity but overall the evidence for this is equivocal. In this study, we investigated how the selection of different physical activity assessment instruments affects the detected relationship between biological maturation and late primary school children's physical activity. Altogether, 175 children (97 girls, 78 boys) aged 10.6±0.3 years completed the PAQ-C self-report questionnaire and wore ActiGraph GT1M accelerometers for 5 consecutive days. Maturity status was predicted by estimating attainment of age at peak height velocity. Following initial exploration of sex differences in PAQ-C (t-test) and multiple ActiGraph outcome variables (MANOVA), the influence of maturity status was controlled using ANCOVA and MANCOVA. Unadjusted analyses revealed that boys were significantly more active than girls according to the PAQ-C (P<0.0001, d=0.52) and ActiGraph (P<0.0001, d=0.36–0.72). After controlling for maturity status, the differences in PAQ-C scores increased (P=0.001, d=0.64), but the significant differences disappeared for the ActiGraph data (P=0.36, d=0.17–0.33). The detected relationship between maturity status and late primary school children's physical activity is dependent on the physical activity assessment tool employed, reflecting the different aspects of physical activity captured by the respective measures.     

Constructive readings of interactive episodes: examining ethics in physical education from a social constructionist perspective

In this paper we illustrate how ways of thinking about ethics are tied up with sport and physical education practice and introduce an alternative approach that can help to develop ethical pedagogies. We begin by locating socio-moral education in physical education within historical and contemporary pedagogical scholarship. Our argument is that the work of today's physical educators is still shaped by claims that were made about school sport in the nineteenth century and that sport scholars have long had difficulties proving these claims empirically. Rather than search for data that can confirm or refute claims of moral learning, we examine how incidents related to moral behaviour occur during physical education lessons. To do this we draw on data from an ethnographic investigation of a school in North Western Switzerland. Specifically, we present three episodes of interaction in three different physical education lessons. To make sense of these episodes, we introduce a social constructionist perspective. The main assumptions of this perspective are: (1) meanings are created through dialogue and consensus and are context-relative; (2) interactions between people are joint accomplishments; and (3) contexts affect how people interact with one another. Equipped with a constructionist framework, we then inspect the interactive episodes more closely. We include brief discussions of how constructionist understandings might inform ethics pedagogies in the future, suggesting that practitioners should be cautious of universal understandings of ethics, consider pupils as members of communities that are held together by shared practices, provide space for pupils to position themselves differently during lessons and, finally, account for contextual factors when evaluating pupils’ actions.     

Programming Time as a Function of Movement Constraint

Abstract

Although the benefits of exercise are well documented, an international problem of physical inactivity exists. More research, especially theory based, has been recommended. One promising approach for studying exercise behavior is that proposed in the Transtheoretical Model (TTM) of behavior change. This model, however, has received minimal cross-cultural attention and, relative to the current study, measurement instruments have only recently been translated into the Finnish language. The purpose of this study was to assess American and Finnish college students' exercise behaviors on the basis of TTM. Participants were American (n = 169) and Finnish (n = 168) college students who completed language-specific measures of exercise behavior, stage of change, processes of change, decisional balance, self-efficacy, and temptation. The only cultural difference observed was that the American participants rated themselves higher on barrier self-efficacy relative to the Finnish participants. Regardless of nationality or gender, participants classified by their stage of change differed on all the core constructs assessed. These results generally support the utility of TTM for understanding American and Finnish college students' exercise behavior.
