Context Of Physical Activity Research Articles

Self-compassion improves barrier self-efficacy and subsequently physical activity: A test of longitudinal mediation using a representative sample of the United Kingdom.

Self-compassion, which directs the awareness of suffering, sympathetic concerns and caring motives towards oneself, is an important psychological quality and resource for health and well-being. In the context of physical activity, self-compassion can help individuals overcome obstacles, recuperate from a setback or a lapse and engage in regular physical activity. The present research was the first to examine the longitudinal effects of self-compassion on physical activity and the mediation role of barrier self-efficacy of such effects. We recruited a national representative sample of 654 UK adults and followed them over three timepoints across 9 months. At each time point, participants completed an online survey assessing levels of state self-compassion, barrier self-efficacy and physical activity behaviours. We examined the longitudinal effects of self-compassion on physical activity and the mediation role of barrier self-efficacy. Baseline state self-compassion consistently correlated with physical activity levels at Times 2 and 3. Barrier self-efficacy at Time 2 mediated the longitudinal effect of baseline state self-compassion on Time 3 physical activity, after controlling for within- (e.g., Time 1 on Time 2 self-compassion) and between-person variations (e.g., covariance of self-compassion and physical activity within a timepoint). Adopting a self-compassionate mind facilitates engagement and maintenance of physical activity. Future studies could consider accelerometer-based physical activity measures and develop and validate a more context-specific state self-compassion measure tailored for physical activity contexts. Researchers and practitioners should consider incorporating self-compassion to future interventions and education programmes for promoting physical activity.

Basic Psychological Need Satisfaction as Correlates of Physical Activity Trajectories During Adolescence.

This analysis aimed to (1) identify longitudinal joint trajectories of participation in organized and unorganized physical activity contexts, and level of daily moderate-to-vigorous physical activity (MVPA) and (2) assess whether basic psychological need satisfaction during adolescence differentiates between membership in different physical activity trajectories. Participants (n = 888; 56% girls) reported their involvement in 36 different physical activities, level of MVPA, and their perceived satisfaction of competence, autonomy, and relatedness satisfaction in physical activity up to three times per year, over 8 years (from ages 10 to 17 years). Group-based multi-trajectory models were used to identify longitudinal joint trajectories of physical activity participation. We estimated a multinomial logistic regression model for membership in a physical activity trajectory by including individual-level intercepts and slopes for each psychological need obtained using mixed models over the 24 cycles modelized as natural cubic splines. Five longitudinal trajectory groups emerged: Non-participants, Dropouts, Active in unorganized physical activities, Active in organized physical activities, and Active through a variety of activities. Relative to Non-participants, we identify a dose-response relationship in baseline competence and membership in the higher active trajectory groups. In addition, a positive change in competence in early adolescence predicted membership in all three Active trajectory groups.

Older Métis Adults’ Experiences of Physical Activity and Implications to Health Providers

Physical activity supports health and wellness, and specifically supports healthy aging. Little is known about the experiences of older Métis adults with physical activity through their lifespan and how this has impacted wellness. This study was co-constructed with 12 older Métis adults in Sakitawak (Île-à-la-Crosse) Saskatchewan using a participatory action approach, two-eyed seeing and the ontology of Breath of Life Theory, as described by Cindy Blackstock. Older Métis adults described physical activity within three themes, Wahkotowin (Related to Everything), Ahkameyimowin (Never Give up), and E ti Meyo Matshohot (Becoming/Living a Better Life). The results of this study have implications for health care professions which are founded within biomedical and biopsychosocial models. We consider the context and experiences of physical activity among Indigenous populations in Canada to better address the gaps and identify practices that aim to support population health.

Developing community-based physical activity interventions and recreational programming for children in rural and smaller urban centres: a qualitative exploration of service provider and parent experiences

BackgroundChildren’s physical inactivity is a persisting international public health concern. While there is a large body of literature examining physical activity interventions for children, the unique physical activity context of low-density communities in rural areas and smaller urban centres remains largely underexplored. With an influx of families migrating to rural communities and small towns, evaluations of health promotion efforts that support physical activity are needed to ensure they are meeting the needs of the growing populations in these settings. The aim of this community-based research was to explore service providers’ and parents’ perspectives on physical activity opportunities available in their community and recommendations toward the development and implementation of efficacious physical activity programming for children in rural communities and smaller urban centres.MethodsThree in-person community forums with recreation service providers (n = 37 participants) and 1 online community forum with the parents of school-aged children (n = 9 participants) were hosted. An online survey and Mentimeter activity were conducted prior to the community forums to gather participants’ views on the barriers and facilitators to physical activities and suggestions for activity-promoting programs. The service provider and parent discussions were audio-recorded, transcribed verbatim, and analyzed following a deductive approach guided by Hseih and Shannon’s (2005) procedure for direct content analysis. A code list developed from the responses to the pre-forum survey and Mentimeter activity was used to guide the analysis and category development.ResultsSeven distinct categories related to the existing physical activity opportunities and recommendations for programs in rural communities and smaller urban centres were identified during the analysis: (1) Recovery from Pandemic-Related Measures, (2) Knowledge and Access to Programs, (3) Availability, (4) Personnel Support, (5) Quality of Programs and Facilities, (6) Expenses and Subsidies, and (7) Inclusivity and Preferences.ConclusionTo improve the health and well-being of children who reside in low-density areas, the results of this study highlight service provider and parent recommendations when developing and implementing community-based physical activity programs and interventions in rural and smaller urban settings, including skill development programs, non-competitive activity options, maximizing existing spaces for activities, and financial support.

The Value of an Informal Before-School Exercise Opportunity for Adolescent Girls Living in a Low-Socioeconomic Community.

Physical activity is beneficial to physical, social, and emotional well-being, and schools are required to provide opportunities to engage in physical activity. While physical education and school sport have been extensively researched, little is known about the value of informal, unstructured, exercise opportunities. This study involved interviews with 19 adolescent girls who attended "extra" exercise opportunities provided by their school. The 3 opportunities were: (1) informal before-school exercise sessions at school, (2) before-school sport training, and (3) externally provided exercise sessions in a community setting during school hours. Students perceived all opportunities as valuable with benefits to confidence, social well-being, and emotional well-being. The informal exercise sessions held greater benefits to confidence as confidence transferred from the physical activity context into the academic classroom more so than for those participating in sport. Social benefits were greater for those exercising before school as this opportunity created new relationships with teachers and with students from other classes and year groups. The opportunity to engage in informal exercise with peers before school widened social networks, increased confidence, changed the overall school climate, and increased attendance.

Mapping the ‘lifelong journey’ of physical literacy: a biographical assessment method for the physical activity and health context

ABSTRACT Physical literacy (PL) describes individuals’ unique relationship with physical activity by integrating physical, cognitive, affective, and social aspects. The person-centered concept highlights a ‘lifelong journey’ for each individual and postulates beneficial effects on biopsychosocial health. Despite extensive suggestions on how to assess the concept, no instrument has so far sufficiently aligned with these ‘individual journeys’ for PL. Therefore, the goal of this conceptual article is to introduce the biographical PL mapping (BMAP-PL) as a purposive, flexible, and paradigmatically open method for the broad physical activity and health context. Intending to provoke individual narratives by plotting domain-driven courses across the lifespan, the BMAP-PL involves four sequential phases guided by a trained facilitator: (a) introduction and overview; (b) personalization and registration of life events; (c) evaluation and biographical visualization of PL dimensions; (d) final overview. The idiosyncratic courses can undergo both qualitative and quantitative analysis, including a potential for synthetic integration. Qualitative analyses can span the identification of life events, transition phenomena, domain-differential analyses, and inter-individual patterns via narrative analysis, thematic analysis, typological analysis, or the grounded theory approach. We suggest quantitative analyses with descriptive and inferential statistical potential on the intra-individual, inter-individual, and group/population level. Given the profound cognitive engagement with the complex behavior of physical activity, BMAP-PL allows for a smooth transition to interventional endeavors (e.g. self-exploration of identity facets, prospective projections, goal setting). The application of the method has value for both research and practice but is based on requirements on the personal and atmospheric level. Emphasizing the need to complement the conceptual ideas through empirical data, we conclude by outlining an agenda for future activities.

Myokine secretion during moderate-intensity physical activity: Dose-response of interleukin 6 to walking duration.

During vigorous physical activity, contracting muscles secrete a variety of immunomodulatory and metabolic factors called myokines that perform a variety of functions. Foremost among these is interleukin 6 (IL-6), which increases fatty acid mobilization and stimulates anti-inflammatory cytokine release. Despite being well characterized in vigorous exercise contexts, whether IL-6 is secreted during moderate-intensity activities such as walking is unclear. This is especially pertinent as regular walking is one of the oldest and most common forms of physical activity and comes with a variety of health benefits, which may be coordinated in part by IL-6 signaling. To test the hypothesis that IL-6 release occurs during evolutionarily normal physical activity contexts like long distance walking, we performed a dose-response experiment to test the effect of walking duration on IL-6 secretion. Thirteen participants completed four moderate-intensity walking trials (55% HRmax) of varying durations (30 min, 1 h, 2 h, and 3 h) in a randomized order with intervening washout periods of at least 1 week. Using a linear mixed effects model, we found that IL-6 levels modestly increased during only the 2 hand 3 h walking trials. These results suggest that small frequent increases in IL-6 signaling may be an important mechanism underlying the health benefits of regular walking. Furthermore, this finding raises the possibility that IL-6 secretion is an adaptation to fuel physical activity, especially during periods of negative energy balance.

Association between Depressive Symptoms, Physical Activity, and Health Factors in Hispanic Emerging Adults.

Physical activity is a modifiable lifestyle behavior known for reducing symptoms of and being a risk factor for depression and mental health disorders. However, emerging adults (ages 18-25) struggle to meet recommended amounts. In this study, we explore the association between physical activity, depressive symptoms, and health factors in 137 Hispanic emerging adults. Using a cross-sectional survey design, sociodemographic information, depressive symptoms (CES-D score), physical activity (IPAQ score), body composition, and blood pressure measures were obtained. Statistical analyses included correlation and regression analyses. More than half of the participants demonstrated depressive symptomology (59.1%) and body fat percentage greater than 25% (64.2%). Body fat percentage, lean body mass, stress, and heart rate demonstrated notable associations with depressive symptoms and physical activity. When measured continuously and categorically, IPAQ was not a significant predictor of depressive symptoms. When used as a binary variable with a cutoff of 600 MET min/week, IPAQ score revealed a negative relationship with CES-D score (β = -0.169, SE = 2.748, p = 0.034). Our results indicate that a threshold of physical activity, 600 MET min/week, may confer protective effects against depressive symptoms. Future research should investigate the context and quality of physical activity to address mental health disparities in this underrepresented population.

Associations of smart device apps with and without a perceived self-efficacy component in a physical activity context with BMI.

Smart device apps can be used to promote physical activity, decrease sedentariness, or increase self-efficacy to get active in college students, possibly reducing their obesity risk. This study assessed associations of college students' smart device use with body mass index (BMI), expecting associations between physical activity parameters and self-efficacy with BMI, moderated by app type. In an online survey, app data of a week from student's devices, weight, height, physical activity, and self-efficacy to get active were collected from 120 students. Apps were categorized "physical activity," "physical activity with a self-efficacy component," or "unrelated." Use time of physical activity apps is not associated with BMI, while self-efficacy app time show negative and unrelated app time positive associations. Self-efficacy may be an important component in app design for obesity risk reduction of college students. Test economy was low, which is why future studies need to concentrate on better data extraction methods.

Examining associations between physical activity context and children meeting daily physical activity guidelines: the role of outdoor play, sports, and other organized activities.

Less than one-quarter of US children meet physical activity (PA) guidelines. Understanding the context in which PA occurs and how these contexts may play a role in meeting PA guidelines is an essential step toward developing effective behavioral interventions. The purpose of this study was to examine associations between PA context (sports participation, participation in other organized physical activities, active travel to school, and outdoor play) and the number of days children met PA guidelines in a representative sample of children living in Texas. We analyzed cross-sectional data from a statewide sample of fourth-grade children in Texas who completed the 2019-2020 Texas School Physical Activity and Nutrition (Texas SPAN) survey. The Texas SPAN survey was designed to monitor the statewide prevalence of overweight/obesity among school children and assess habitual self-reported obesity-related behaviors, including diet and PA. Weighted Poisson regression models were employed to examine the associations between PA contexts (sports participation, participation in other organized physical activities, active travel to school, and outdoor play) and the number of days children met PA guidelines, adjusting for sex, race/ethnicity, overweight/obesity, urban-rural status, and economic disadvantage. A total of 16.7% of fourth-grade children met physical activity guidelines every day during the week (mean age = 9.4 ± 0.6 years; female = 48.7, 51.8% Hispanic, mean days meeting PA guideline = 3.6 ± 2.3 days). One in ten (11.2%) children did not meet daily PA guidelines on any day of the week, and 72.1% met them between 1 and 6 days. Participating in sports (b = 0.22, 95%CI:0.14, 0.30), any other organized physical activities (b=0.13, 95%CI:0.017, 0.19), and playing outdoors 1-3 days (b = 0.25, 95%CI:0.04, 0.46) and 4-7 days in the past week (b = 0.77, 95%CI:0.57, 0.97) was significantly and positively associated with the number of days children met PA guidelines. Participating in sports, participating in other organized physical activities, and playing outdoors may beneficially influence the number of days children meet PA guidelines. PA programs should consider these contextual factors and investigate how to promote organized activities and outdoor play effectively and appropriately among children.

Analysis of Actual Fitness Supplement Consumption among Health and Fitness Enthusiasts.

With the rising popularity of fitness supplements, understanding the factors driving their consumption behaviors is crucial. This study investigated the actual consumption of fitness supplements utilizing the Theory of Planned Behavior (TPB), Health Belief Model (HBM), and the Theory of Effort Minimization in Physical Activity (TEMPA) frameworks. The TPB provided insights into how attitudes, subjective norms, and perceived behavioral control influence individuals' intentions to consume fitness supplements. Additionally, the HBM sheds light on perceived effectiveness, benefits, barriers, and health motivation related to supplement consumption. Integrating the TEMPA framework further investigated the role of effort minimization in physical activity contexts. Through an online questionnaire, data were collected from a sample of 250 fitness supplement-consuming respondents. SEM analysis revealed significant associations between behavioral intentions and attitudes, perceived behavioral control, health motivation, and controlled precursors. However, it was seen that subjective norms, perceived effectiveness, perceived benefits, and automatic precursors were deemed insignificant. The findings contribute to a comprehensive understanding of the factors shaping actual consumption behaviors, offering valuable implications for marketers, health professionals, and policymakers seeking to promote informed and responsible supplement use among health and fitness enthusiasts.

Redefining Education in Sports Sciences: A Theoretical Study for Integrating Competency-Based Learning for Sustainable Employment in Spain

In the Spanish context, Sports Sciences education is evolving to emphasize competency-based learning, crucial for adapting to the dynamic global landscape and labor market. This opinion article highlights the shift towards integrating generic and specific competencies, essential for automation and artificial intelligence, aligning with Sustainable Development Goal (SDG) 8’s focus on sustainable economic growth and employment. Despite the recognized importance of these competencies for economic sustainability and job readiness, the literature on this framework, particularly within the context of physical activity and Sports Sciences in Spain, remains underexplored. This paper is structured to first address the current state of the problem, followed by a conceptualization of competencies, including types of competencies. It then analyzes professional competencies within the realm of Physical Activity and Sports Sciences in Spain, moving towards the implementation and evaluation of these competencies in the classroom setting. By bridging the gap between educational outcomes and market demands, this work calls for ongoing research and pedagogical innovation to equip future professionals with the necessary skills for success. This approach not only prepares students for the future labor market but also contributes to the broader economic and sustainable development goals envisioned by SDG 8.

Physical Literacy in the Context of Climate Change: Is There a Need for Further Refinement of the Concept?

The concept of physical literacy (PL) has witnessed enormous popularity in recent years and has undergone substantial theoretical evolvement during the last 2 decades. However, the research field pertaining to PL has not yet initiated discussions around the challenges of climate change and the alignment with conceptualizations of planetary health. Therefore, we argue that the consideration of an "ecological domain" for individual physical activity, in the form of ecological awareness, would further evolve the concept. We illustrate how to potentially integrate adjustments within the most frequent PL definitions of the field (eg,those in Australia, Canada, England, Ireland, the United States, or by the International Physical Literacy Association) without questioning the entire integrity of these elaborate conceptualizations. An ecological domain of PL would not only interact with the postulated physical, cognitive, psychological/affective, and social domains of PL but also have important implications for the (re)design of interventions and practices in physical activity contexts. We call the scientific community, both on national and international scales, to intensify the discussions and initiate a research agenda involving an "ecological domain" of PL.

Supplementation for Performance and Health in Patients with Phenylketonuria: An Exercise-Based Approach to Improving Dietary Adherence.

Supplementation is crucial for improving performance and health in phenylketonuria (PKU) patients, who face dietary challenges. Proteins are vital for athletes, supporting muscle growth, minimizing catabolism, and aiding muscle repair and glycogen replenishment post-exercise. However, PKU individuals must limit phenylalanine (Phe) intake, requiring supplementation with Phe-free amino acids or glycomacropeptides. Tailored to meet nutritional needs, these substitutes lack Phe but fulfill protein requirements. Due to limited supplement availability, athletes with PKU may need higher protein intake. Various factors affect tolerated Phe levels, including supplement quantity and age. Adhering to supplement regimens optimizes performance and addresses PKU challenges. Strategically-timed protein substitutes can safely enhance muscle synthesis and sports performance. Individualized intake is essential for optimal outcomes, recognizing proteins' multifaceted role. Here, we explore protein substitute supplementation in PKU patients within the context of physical activity, considering limited evidence.

The impact of the COVID-19 pandemic on the physical activity environment in English primary schools: a multi-perspective qualitative analysis.

The COVID-19 lockdowns and social distancing measures, including school closures, had a major impact on children's physical activity in England, with data showing an initial reduction in activity in the short-term post-lockdown phase of the pandemic followed by a recovery on average in the medium-term post-lockdown period. The school environment is an important context for child physical activity. The purpose of this study is to understand the changes that took place to school physical activity environments once schools reopened after lockdowns. This information will improve understanding of why changes to children's physical activity have occurred over the course of the pandemic and the implications for future promotion of physical activity in schools. Interviews with parents (n = 43), school staff (n = 18) and focus groups with 10- to 11-year-old children (participant n = 92) were conducted at two time points: between September-December 2021 and February-July 2022. Interview and focus group guides covered the impact of the pandemic on child physical activity and changes to this over time. The framework method was used for analysis. Three themes and three subthemes were generated: (1) the return to school; (2) over-pressured staff and environment and (3) the uneven impact of the pandemic. Theme 3 consists of three subthemes: (a) retained pandemic policies, (b) impact on physical activity culture and (c) different children need different things. Conducting this research in schools during ongoing COVID-19 disruptions was a challenge and may have limited school and participant participation, particularly school staff. The parent interview sample is predominantly female, active and of higher socioeconomic status, so the experiences of male, less active and lower socioeconomic parents are limited. This study suggests that the impact of COVID-19 on child physical activity is uneven, affecting some children more than others. Future work is therefore needed to explore the details of this potential diverging experience. The COVID-19 pandemic, school closures and post-lockdown school policies have impacted upon primary school physical activity environments. The post-lockdown school environment is highly pressured, impacting the extent to which schools can support and encourage child physical activity. Future research is needed to further explore the impact of post-lockdown changes on physical activity environments in schools, particularly over the longer term, as schools continue to adapt post lockdowns. Strategies required to support school physical activity environments must be context specific and sensitive to these changes, pressures and needs. This article presents independent research funded by the National Institute for Health and Care Research (NIHR) Public Health Research programme as award number NIHR131847.

School Websites: Local Contexts of Physical Activity and Physical Education Information

As the digital age continues to evolve, websites provide a potential way for physical education (PE) programs and schools to offer information on how they handle the topic of physical activity (PA). Charter schooling and charter schools have become substantially prevalent over the last 30 years, and the trend does not appear to be slowing. A variety of studies to gather information about PE and PA have already been conducted (Hill et al., 2010; Kahan & McKenzie, 2020; Kahan & McKenzie, 2021; Kahan et al., 2019). Specifically, Kahan and McKenzie have performed a variety of website analyses in the state of California, content-analyzing the sites to surveil PA and PE information on school websites. Further, they have looked at school factors such as local demographics, school size, religious affiliation, and public/private/charter affiliation. By following an intended partial-replication protocol, we looked to surveil Arizona-based charter schools to study the local context of another charter “hotspot.” We collected data through data collection protocols communicated by Dr. Kahan (circa June 2019). By conducting a quantitative descriptive study, we looked at characteristics and ran binary regression models to look for inferentially underlying trends. Descriptively, most findings mirrored those of previous research, with marginal presence of any information specific to PE and PA. We found significant predictors for website information for the categories of sports, PE frequency, presence of a PE teacher, school levels, and recess. We found similarities and differences between school types, but these targeted certain factors that may be expanded on or used to guide future website analyses both in Arizona and nationally. This is significant because as the prevalence of charter schools continues to grow, it is important to keep students sufficiently physically active and physically educated throughout a school day.

Sleep, activity, and diet in harmony: unveiling the relationships of chronotype, sleep quality, physical activity, and dietary intake.

This cross-sectional study aims to explore the intricate relationships among chronotype, sleep quality, physical activity, and dietary intake in a diverse cohort of 3,072 (50.2% female) participants residing in İstanbul, Türkiye. This study utilized established measurement tools, including the Morningness-Eveningness Questionnaire (MEQ) to assess chronotype, the Pittsburgh Sleep Quality Index (PSQI) to evaluate sleep quality, the International Physical Activity Questionnaire Short Form (IPAQ-SF) to measure physical activity, and a 24-h dietary recall method to assess dietary intake. The findings of this study revealed compelling associations. Firstly, a robust association was observed between sleep quality and chronotype (OR: 2.265; 95% CI: 1.954-2.626; p < 0.001) as well as physical activity (OR: 0.836; 95% CI: 0.750-0.932; p = 0.002). Specifically, evening chronotypes are more likely to have poor sleep quality, while highly active individuals tend to report lower sleep quality. Transitioning from inactivity to high activity was associated with a 16.4% increase in the odds of transitioning from normal to poor sleep, while a shift from an evening to a morning chronotype was linked to a substantial 126.5-fold increase in the odds of moving from poor to normal sleep. Additionally, morning chronotypes also display distinctive dietary patterns, characterized by higher energy, protein, and fat intake, and reduced carbohydrate intake. Poor sleep quality is associated with increased energy and macronutrient consumption. These findings underscore the intricate relationships of chrononutrition within the context of sleep quality, physical activity, and dietary choices. The study underscores the significance of personalized interventions to effectively address specific health behaviors, highlighting the complexity of chrononutrition's role in promoting overall health and wellbeing.

WIT FITS: Effects of Weight Stigma Intervention on Exercise Professionals’ Attitudes Toward Fatness: A Randomized Controlled Trial

Exercise professionals often hold anti-fat attitudes, which contribute to weight stigma and discrimination in physical activity contexts. This study examined the effects of an online weight stigma intervention on exercise professionals’ attitudes toward fatness. Participants were 105 exercise professionals who were employed at least part-time at university recreation centers in the United States. In this randomized controlled trial, participants were randomized into an intervention online course to decrease weight stigma or a control online course to learn about communication techniques to enhance motivation for physical activity. Attitudes about fatness were assessed at pre- and post-course using the Fat Attitudes Assessment Toolkit (FAAT). There were significant increases in the fat acceptance composite score in the intervention group compared to the control group, suggesting recreation center staff who completed the intervention WIT FITS course experienced more positive evaluations of fat people as a result of the intervention.

Conceptualisation and Measurement of Social Cohesion within the Sport and Physical Activity Context: A Scoping Review.

Sport, physical activity and social cohesion are increasingly linked within the academic literature. Indeed, studies recognise both the importance of social cohesion for promoting physical activity and the potential of sport to support social cohesion. Up until now, however, the ways in which social cohesion has been defined and measured in the context of sport and physical activity have not been the subject of much academic attention. Through a scoping review of studies measuring social cohesion in the sport and physical activity context, we aim to uncover how social cohesion is defined and measured, thus allowing us to better grasp how the concept is understood and operationalised in this field. As such, full-text inclusion occurred when studies quantitatively measured social cohesion through a questionnaire/survey instrument in connection with sport or physical activity participation or within programmes using sport to foster social cohesion. A total of 40 papers were included in the review, showing broad support for the argument that social cohesion is positively related to sport or physical activity participation. However, the retained texts engage on only a surface level with the concept of social cohesion, with around half not defining the term and the associated measurement tools using only a fraction of the dimensions typically associated with social cohesion. To conclude, we propose future directions to enhance conceptual engagement with and measurement of social cohesion.

Gender difference in “second-shift” physical activity: New insights from analyzing accelerometry data in a nationally representative sample

The gendered organization of daily activities results in differential contexts of physical activity (PA) for the working population, especially during the “second shift” – a time window dominated by household-based activities. Existing research predominantly relies on self-reported leisure-time activities, yielding a partial understanding of gender difference in the source, timing, and accumulation pattern of PA. To address these limitations, this study draws on the interplay between work and family to understand how they shape gender difference in household-based PA across occupational groups. It combines work schedule and accelerometry PA data from the 2005–2006 National Health and Nutrition Examination Survey (NHANES), which permits our study of second-shift PA on workdays among full-time workers, aged 20 to 49, with a regular daytime schedule. To capture different aspects of second-shift PA, the PA outcomes are measured as both volume and accumulation patterns during time windows following (i.e., 6pm–9pm) and prior to typical working hours (7:30am-8:30am). Using generalized estimating equations, we estimate gender differences in the volume and fragmentation of second-shift PA. Overall, women with a full-time job exhibit both higher volume and higher fragmentation of second-shift PA than their male counterparts. The occupational group moderates such gender difference in PA. The gender gaps in PA volume and fragmentation are only evident for professional workers, whereas the second shift represents a gender-neutral context for PA accumulation for non-professional groups. These findings are supported by a secondary analysis when analyzing the whole-day PA data using functional data analysis. Such social patterning of second-shift PA calls for further research on gendered PA under the interplay of work and family beyond the usual focus on leisure activities.
