Potential moderators of day-to-day variability in children’s physical activity patterns

Little is known about whether physical activity compensation occurs and, if so, what are potential moderators of such responses. This study examined whether children’s physical activity, sedentary time and energy expenditure on one day was associated with these behaviours the following day, and what factors may moderate observed associations. One hundred and twenty-seven children (8–11 years) wore an ActiGraph accelerometer for eight days. Time spent in sedentary time and physical activity was obtained. Daily energy expenditure was also assessed using a SenseWear Armband (n=98). Moderators examined were sex, age, BMI, fitness, and fundamental movement skills (FMS). Multilevel analyses were conducted using generalized mixed models. On any given day, every additional 10 minutes spent in moderate-to-vigorous physical activity (MVPA) was associated with 9.3 minutes less MVPA the following day. Every additional 10kcal expended on one day was associated with 2.9 fewer kcal expended the following day. Additional time spent sedentary on any given day was associated with less light physical activity the following day in children with lower FMS. The results are largely consistent with the compensation hypothesis, with children appearing to compensate their activity between days. Strategies to minimise potential compensatory changes may be needed for children overall rather than for specific population sub-groups.     

Tourists’ motivations for practicing physical activity: a home-holiday comparison

The aim of the study is to examine motivations for practicing physical activity on holiday. In particular, the objective is to compare home habits to holiday experiences and identify differences and commonalities in individuals’ attitude towards physical activity. The methodological approach is to conduct a survey among tourists during a holiday stay by employing a self-administered questionnaire. Findings identify three motivational factors (Decompress, Performance and Shape) and a cluster analysis reveals the coexistence of four different profiles of physical activity performers (Shapers, All-around Pursuers, Sport Performers and Decompress Seekers). Results show diffuse distinctiveness of motivations for practicing physical activity on holiday compared to the motivations for practicing it at home. Specifically, Decompress motives increase and Shape motives decrease. The study contributes to deepen the knowledge on consumer behaviour in leisure and holiday and provides useful insights to destination managers and policy-maker to address the sport tourism market.     

A systematic review of school-based physical activity interventions on children’s wellbeing

Purpose: The aim of this study was to review the effect of school-based physical activity interventions on children’s wellbeing.

Method: A systematic search of school-based physical activity studies was conducted using EBSCOhost PsycInfo, EBSCOhost Medline and Web of Science. Initially 995 studies were retrieved and, following the removal of duplicates, the titles and abstracts of 984 studies were screened. This screening identified 53 relevant studies from which 42 were excluded, resulting in 11 articles being reviewed.

Results: Three studies reported a positive increase in wellbeing; however, only one of those studies also significantly increased physical activity. It was apparent that the measurement of wellbeing and physical activity was inconsistent across studies, making conclusions difficult to draw. The wellbeing measures used neglected to account for the children’s perspectives of wellbeing.

Conclusions: The effect of a physical activity intervention on increasing wellbeing appears to be more complex than originally believed. The complexity may in part be due to methodological issues and the choice of wellbeing and physical activity measurement. We recommend that future physical activity interventions include a measure of wellbeing developed from the child’s perspective, and that future reviews narrow the search to only interventions that have had success at increasing physical activity before exploring effects on wellbeing.     

Assembling the privatisation of physical education and the ‘inexpert’ teacher

In this article, I examine the practice of outsourcing physical education (PE) lessons to external sports organisations. I draw from ethnographic research conducted with two primary schools in New Zealand to illuminate how outsourcing interconnects with the privatisation of education. Using Foucault's notion of government, I demonstrate how schools’ employment of four outside providers worked to govern teachers towards certain ends. In addition, I drew on the analytical framework of the assemblage to examine how the dual notions of the inexpert classroom teacher and the expert outside provider converged with the discourse of ‘PE as sport’, neoliberalism, Kiwisport, National Standards, professional development and multi-sector partnerships to form a privatisation assemblage. I argue that the privatisation assemblage worked to restrict and constrain teachers’ possible thoughts and actions, making teachers’ ‘choice’ to outsource PE one that they understood as both pragmatic, in terms of time investment, and educationally valuable, in so far as they perceived themselves as lacking the requisite expertise. I also argue that outsourcing and the privatisation of PE is problematic as it did not necessarily work in the best interests of teachers or students. I suggest further research is necessary to interrogate and make visible how the disparate elements of the privatisation assemblage are made to hold together, as well as how the fragile connections between these elements may be placed under pressure. The notion that outside providers are expert PE teachers and classroom teachers are inexpert is a critical aspect of the assemblage that should be challenged and resisted.     

Program providers’ perspective: Recruitment and retention strategies for women in physical activity programs

This paper examined the perceptions from eight program providers in Victoria, Australia regarding the recruitment and retention of women in physical activity programs. Eight case studies were conducted. Each involved an in-depth interview with a provider of a successful physical activity program for women. Inductive content analysis generated common themes related to key aspects that enable the recruitment or retention of women. Three core themes were identified, namely creating an environment for women to exercise; facilitating involvement; and promoting the program to the community. In this study, we applied the social-ecological model to determine the levels of influence and the opportunities in the core themes to further enable the recruitment and retention of women in physical activity programs. A key conclusion was that links with several related community organisations leads to both the successful recruitment and the enhanced retention of women in physical activity programs.     

The translation of preschoolers’ physical activity guidelines into a daily step count target

This study aimed at translating the physical activity (PA) guideline (180 min of total PA per day) into a step count target in preschoolers. 535 Flemish preschoolers (mean age: 4.41 ± 0.58) wore an ActiGraph accelerometer (GT1M, GT3X and GT3X+) – with activated step count function – for four consecutive days. The step count target was calculated from the accelerometer output using a regression equation, applying four different cut-points for light-to-vigorous PA: Pate, Evenson, Reilly, and Van Cauwenberghe. The present analysis showed that 180 min of total PA per day is equivalent to the following step count targets: 5,274 steps/day using the Pate cut-point, 4,653 steps/day using the Evenson cut-point, 11,379 steps/day using the Reilly cut-point and 13,326 steps/day using the Van Cauwenberghe cut-point. Future studies should focus on achieving consensus on which cut-points to use in preschoolers before a definite step count target in preschoolers can be proposed. Until then, we propose to use a provisional step count target of 11,500 steps/day as this step count target is attainable, realistic and helpful in promoting preschoolers’ PA.     

Comparison of children’s free-living physical activity derived from wrist and hip raw accelerations during the segmented week

This study assessed children’s physical activity (PA) levels derived from wrist-worn GENEActiv and hip-worn ActiGraph GT3X+ accelerometers and examined the comparability of PA levels between the two devices throughout the segmented week. One hundred and twenty-nine 9–10-year-old children (79 girls) wore a GENEActiv (GAwrist) and ActiGraph GT3X+ (AGhip) accelerometer on the left wrist and right hip, respectively, for 7 days. Mean minutes of light PA (LPA) and moderate-to-vigorous PA (MVPA) per weekday (whole-day, before-school, school and after-school) and weekend day (whole-day, morning and afternoon–evening) segments were calculated, and expressed as percentage of segment time. Repeated measures analysis of variance examined differences in LPA and MVPA between GAwrist and AGhip for each time segment. Bland–Altman plots assessed between-device agreement for LPA and MVPA for whole weekday and whole weekend day segments. Correlations between GAwrist and AGhip were weak for LPA (r = 0.18–0.28), but strong for MVPA (r = 0.80–0.86). LPA and MVPA levels during all weekday and weekend day segments were significantly higher for GAwrist than AGhip (p < 0.001). The largest inter-device percent difference of 26% was observed in LPA during the school day segment. Our data suggest that correction factors are needed to improve raw PA level comparability between GAwrist and AGhip.     

Can athletes’ reports of self-regulated learning distinguish deliberate practice from physical preparation activity?

Sustained persistence in deliberate practice (DP) could be aided by engagement in adaptive motivational and metacognitive types of self-regulated learning (SRL) processes. We examined relationships between SRL and each of DP and physical preparation (PP; e.g., cross-training) in supervised, unsupervised, social and non-social practice contexts. 272 individual-sport athletes (from city to international level; M sport activity = 13.54 hrs/wk; 200 males, ages 18–35) completed the Self-Regulation of Learning Self-Report Scale and reported weekly DP and PP amounts. We found contrasting results depending on specific SRL processes. Self-monitoring was related to DP (total, supervised, social conditions) but inversely related to PP. Effort was inversely related to supervised DP but positively associated with PP. Planning was associated with DP, and reflection and self-efficacy related to PP. We discuss the contrast between DP and PP, highlighting differences in the nature of these practice activities, and self-monitoring as a key SRL process for DP.     

The influence of body discourses on adolescents’ (non)participation in physical activity

Drawing on semi-structured interviews with older adolescents, this article examines how healthism, ideal body discourses and performative body discourses influence their (non)participation in physical activity (PA) and their identity construction concerning exercise, sport and physical education. We illustrate that body transformation through PA, and related slim body desire and the fear of masculinised female bodies, affect adolescents’ decisions to engage in or drop out of sport. Also, a non-hegemonic body shape combined with a display of low physical competence triggers classmate and teachers’ rejection and marginalisation, affecting adolescents’ construction of embodied identities and preventing them from being active. Finally, adolescents who are competent in sport are less influenced by ideal body discourses than by performative body discourses. We highlight the health promotion effects of these hegemonic discourses and suggest strategies to challenge them.     

Looking at the extraordinary success of the ‘Clockwork Orange’: examining the brilliance of total football played by the Netherlands

This essay describes some of the legendary accomplishments of the Netherlands football team in the World Cup and other international tournaments. It focuses on the Dutch teams led by Johan Cruyff and affectionately known as ‘The Clockwork Orange’ because they introduced a modern style of play with precision passing that was referred to as ‘total football’. The Netherlands advanced to the World Cup final in 1974 and 1978, only to lose the championship each time. The study also explores the role of the Dutch coach Rinus Michels and some of Cruyff’s teammates such as Johan Neeskens and Rob Rensenbrink. Looking at the Netherlands’ performances in the European championships and World Cups in the last three decades, the essay attempts to bring out the transformations in Dutch football in post-Cruyff age. Finally, it discusses the team’s rabid and energized fan base, and the ambush marketing scandal that took place during the 2010 World Cup.     

Force–velocity property of leg muscles in individuals of different level of physical fitness

The present study explored the method of testing muscle mechanical properties through the linear force–velocity (F–V) relationships obtained from loaded vertical jumps. Specifically, we hypothesised that the F–V relationship parameters depicting the force, power, and velocity of the tested muscles will differ among individuals of different physical fitness. Strength trained, physically active, and sedentary male participants (N = 10 + 10 + 10; age 20–29 years) were tested on maximum countermovement and squat jumps where manipulation of external loads provided a range of F and V data. The observed F–V relationships of the tested leg muscles were approximately linear and mainly strong (median correlation coefficients ranged from 0.77 to 0.92; all p < 0.05), independently of either the tested group or the jump type. The maximum power revealed higher values in the strength trained than in the physically active and sedentary participants. This difference originated from the differences in F-intercepts, rather than from the V-intercepts. We conclude that the observed parameters could be sensitive enough to detect the differences among both the individuals of different physical fitness and various jump types. The present findings support using loaded vertical jumps and, possibly, other maximum performance multi-joint movements for the assessment of mechanical properties of active muscles.     

Exploring the relation between physical activity and health—a salutogenic approach to physical education

This article takes a point of departure in the debate whether physical education should consider a limited or an increased commitment towards public health goals and a public health agenda. The article further discusses the relationship between physical activity and health, and the perspective of health in physical education. This is done through a critique of the dominance of a pathogenic perspective of health, as well as through a salutogenic approach regarding health as a process. A salutogenic approach makes, as suggested in the article, other questions—salutogenic questions—possible. In this sense, physical activity and movement can be regarded as something more than mere protection against disease or overweight, and by posing salutogenic questions we can enrich our understanding of the relation between physical activity and health, and in consequence richness to the perspective of health in physical education. With a salutogenic approach, the pupils’ unique and common experiences of health, movement, body ideals or outdoor-life can meet a wider perspective of health. This would facilitate a health perspective in physical education that draws attention to the qualities, abilities and knowledge that pupils can develop, and, in the name of learning health, point the way to the possible contribution of physical education in pupils’ health development in terms of how physical education can enrich their lives, strengthen them as healthy citizens and contribute to a sustainable (health) development.     

How valid are wearable physical activity trackers for measuring steps?

Wearable activity trackers have become popular for tracking individual’s daily physical activity, but little information is available to substantiate the validity of these devices in step counts. Thirty-five healthy individuals completed three conditions of activity tracker measurement: walking/jogging on a treadmill, walking over-ground on an indoor track, and a 24-hour free-living condition. Participants wore 10 activity trackers at the same time for both treadmill and over-ground protocol. Of these 10 activity trackers three were randomly given for 24-hour free-living condition. Correlations of steps measured to steps observed were r?=?0.84 and r?=?0.67 on a treadmill and over-ground protocol, respectively. The mean MAPE (mean absolute percentage error) score for all devices and speeds on a treadmill was 8.2% against manually counted steps. The MAPE value was higher for over-ground walking (9.9%) and even higher for the 24-hour free-living period (18.48%) on step counts. Equivalence testing for step count measurement resulted in a significant level within ±5% for the Fitbit Zip, Withings Pulse, and Jawbone UP24 and within ±10% for the Basis B1 band, Garmin VivoFit, and SenseWear Armband Mini. The results show that the Fitbit Zip and Withings Pulse provided the most accurate measures of step count under all three different conditions (i.e. treadmill, over-ground, and 24-hour condition), and considerable variability in accuracy across monitors and also by speeds and conditions.     

Exploring physical education teachers ‘everyday understandings’ of physical literacy

ABSTRACT

In recent years, physical literacy (PL) has been the subject of increased publication, promotion, and speculation in physical education (PE). This research sought to understand how PE teachers interpret PL. We investigated teacher’s conceptualisations, understandings, practices, and ideas of ‘what’ PL stands for through a #Chat conversation with physical educators on Twitter. This generated qualitative data that were interpretively analysed. An ‘everyday philosophy’ of PL emerged from the physical educators’ relationship with the PL concept, alongside the notion that some use social media as a PL advocacy tool. A lack of sophistication was evident in the PE teachers understanding and operationalization of PL. We conclude that perhaps too much time and effort has been spent ‘adapting’ PL to national contexts, personal, and institutional agendas, rather than investing in the pedagogical and content knowledge of PE teachers to deliver on the concept of PL. We suggest that it is empirical research rather than academic opinionating that is needed to establish the validity of PL for PE.     

Listening to students’ silences – a case study examining students’ participation and non-participation in physical education

Background: For years researchers have been engaged in revealing the impact of the hidden curriculum in physical education (PE) on students’ participation and non-participation. The hidden PE curriculum encompasses the knowledge, the relations, the assumptions, the norms and the beliefs that students unconsciously and unintentionally learn through the process of education. As the hidden curriculum reinforces particular values and attitudes among students in a very subtle and often unnoticed fashion, it limits students’ possibilities for becoming aware of, and thus reporting, how the tacit messages communicated through the hidden curriculum impact on their position of participation and non-participation. Thus, in this article, we argue that examining students’ silences, that is the things students do not voice, is significant for the understanding of the impact of the hidden curriculum on students’ participation and non-participation in PE.

Purposes: In this article, we aim to develop insight into students’ silences in order to elucidate how aspects of the hidden curriculum serve to reinforce some students’ non-participation in PE. Much attention has been devoted to particular values and attitudes unintentionally transmitted by teachers in PE. However, in this article, we examine how the everyday exchanges between the students themselves may also convey a hidden set of meanings, that impact on students’ actual experiences of the PE curriculum, and thus mitigate the intended effects of students’ participation.

Research design: The backdrop for this article is a single-case study carried out in a multi-ethnic and co-educational secondary school in Denmark from January to December 2014. The article draws on material collected through focus group interviews with 7th grade students (including participant-diagrams filled out by students) along with observations of their PE classes. The observations took place once a week throughout the whole calendar year.

Findings: In the article, we point to students’ intentional silences that are highly reflective of the normative expectations negotiated within the peer group. In addition, we show that the pressures toward social conformity have a direct impact on the positions of non-participation intentionally taken up by some of the less socially respected students in PE. These students were highly aware that how they behaved in PE and what they voiced in the interviews might have consequences for their peer group connections within PE and for their social reputation among peers outside of PE. In addition, we add to the current literature on student silence by pointing to a category of non-privileged silences. These silences revealed that a minor group of students were not aware of or had not recognized their position as non-participants in PE. Moreover, they appeared unable to imagine that things could be different and to voice a desire for change.

Conclusions: We argue that our findings reveal critical aspects of students’ non-participation that would be difficult to access if we did not listen to, hear and attempt to understand students’ silences. In order to extend the knowledge base on students’ participation and non-participation in PE, we hope that this article may also encourage other researchers to let students’ silences breathe and speak.     

What are the contributory and compensatory relationships between physical education and physical activity in children?

Limited data are available on the contributory and compensatory relationships between physical education and physical activity in children. Four hundred eighty-five (280 girls) children in first through sixth grades wore sealed pedometers during waking hours, including normally scheduled physical education lessons. The least, moderately, and most active children accumulated approximately 1700, 1100, and 2500 more steps/day, respectively, on school days with physical education. No compensatory increases in physical activity were found on school days that did not offer physical education. The implications of the contributory relationship are highlighted by the evidence that 50% of the least active children were at risk for overweight or overweight and that no compensatory increases in physical activity were found on school days when physical education classes were not scheduled.     

Experiencing risk,surveillance, and prosumption: health and physical education students’ perceptions of digitised health and physical activity data

ABSTRACT

Digital technologies are now considered important in shaping young people's engagement in and with health and physical activity. Recent discussions show that the use of digital technologies to track health and fitness may over-emphasize the linear understanding of the body and health generally underpinned by Western health ideologies such as healthism. Other studies have shown the increased use of digital technologies in teaching Health and Physical Education (HPE) and as a means to enhance health and increase physical activity. Despite the opportunities and risks apparent in these studies, little is known about how HPE students make choices, negotiate, and resist or embrace the digitalisation of physical activity, exercise, and more broadly health. This study examines HPE students’ meaning making of risk and surveillance associated with the self-digitisation of exercise. The study further investigates how the concept of ‘prosumption’; the production, curation and consumption of self-data within the context of digitised health and physical activity, is understood. Based on the findings, we have constructed a typology of prosumers that can be used as a pedagogical device to illustrate the various kinds of subject positions students take up with digital technology in health and physical activity. This study extends the current understanding of prosumers by identifying the ‘ambivalent prosumer’. The results provide insights that have direct pedagogical implications in HPE teacher education specifically in the areas of knowledge production and consumption of knowledge through digital technology in health and physical activity.     

Impact of a pedometer-based goal-setting intervention on children’s motivation,motor competence,and physical activity in physical education

Background: School physical education (PE) programs provide a prime environment for interventions that attempt to develop school-aged children’s motor competence and overall physical fitness, while also stimulating competence motivation to engage in physical activity during childhood. It is generally recognized that a pedometer-based intervention strategy combined with a goal-setting strategy may be effective in increasing physical activity participation among school-aged children. The purpose of this study was to evaluate the impact of an 8-week pedometer-based goal-setting intervention on children’s motivation in PE, motor competence, and physical activity.

Methods: A pretest–posttest comparison group design was used with the 8-week intervention (3 days/week for 24 sessions). Participants were 273 (boys?=?136, girls?=?137) students recruited from 3 elementary schools in the US. Classes in each school were randomly allocated to three experimental conditions: (1) an intervention group with a personalized pedometer weekly target to reach in their PE class (N?=?110), (2) an intervention group with the fixed pedometer target range to reach in each PE class based on the recommended criteria (N?=?90), or (3) a control group without intervention (N?=?73).

Analysis/results: The factorial repeated measures MANOVA indicated significant multivariate effects for the group [F(6, 528)?=?12.954, p?Post hoc analyzes showed that both experimental groups had significantly higher expectancy-value beliefs, motor competence, and physical activity compared to the control group (p?Conclusions: Health practitioners should be aware that goal-directed action can contribute to school students’ PE-related achievement motivation, motor competence, and achieving the recommended 60?min of moderate-to-vigorous physical activity.
