Body-related emotions and subsequent physical activity behaviour: An ecological momentary assessment

Body-related shame and guilt are theorized to be time-varying affective determinants of physical activity, yet research has predominantly relied on self-report measures of physical activity and between-person associations. To address these limitations, the present study used ecological momentary assessment to examine within- and between-person associations between body-related shame and guilt, and subsequent time spent in moderate-to-vigorous physical activity (MVPA) measured by continuously worn accelerometers. University students (n = 98; 79.6% female; m_age = 19.45) were prompted 49 times over seven days to report body-related shame and guilt, and wore activPAL accelerometers to monitor movement behaviours. Higher levels of within-person body-related guilt, but not shame, were associated with increased subsequent time spent in MVPA. Contrary to existing literature, neither body-related shame nor guilt demonstrated a significant association with average levels of MVPA between individuals. These findings support theoretical propositions that body-related guilt may impact engagement in physical activity in daily life.     

Psychological,social and physical environmental mediators of the SCORES intervention on physical activity among children living in low-income communities

ObjectivesThis study examined mediation effects of socio-ecological variables on accelerometer-determined physical activity among children in the Supporting Children's Outcomes using Rewards, Exercise and Skills (SCORES) intervention.DesignRandomized control trial mediation analysis.MethodsPrimary school children were randomly assigned the SCORES multi-component intervention or control group for the 12-month study. The outcome was accelerometer derived total moderate-to-vigorous physical activity (MVPA). Hypothesized mediators measured in children were physical activity enjoyment and perceived sport competence and social support. Hypothesized mediators measured in parents were family social support, access to physical activity facilities and equipment at home, and perceived access to physical activity opportunities in the local community. Mediation analyses were conducted using multi-level linear analysis in MPlus.ResultsThere were significant intervention effects for social support from teachers (A = 1.73, SE = 0.88, p = 0.048) and parental perceived access to physical opportunities in the local community (A = 2.69, SE = 1.12, p = 0.016). There were significant associations between changes in perceived sport competence (B = 0.48, SE = 0.36, p = 0.027), parental perceived access to physical activity opportunities in the local community (B = 0.60, SE = 0.26, p = 0.021), and changes in total MVPA. Parental perceived access to physical activity opportunities in the local community was found to have a significant mediating effect on total MVPA (AB = 1.61, 95% CI = 0.06 to 3.95, proportion 13%).ConclusionsParental perceived access to physical activity opportunities in the local community is a potential mechanism of behavior change for children and mediated the effect of the SCORES intervention on objectively measured physical activity.     

Interaction of athletes' resilience and coaches' social support on the stress-burnout relationship: A conjunctive moderation perspective

ObjectiveIn line with Smith's (1986) cognitive-affective model of athletic burnout, the purpose of this study was to examine the conjunctive effects of athletes' resilience and coaches' social support on the relationship between life stress and burnout.DesignCross-sectional, self-report survey.MethodsA total of 218 student-athletes (M_age = 20.04 yrs, SD = 1.32; males = 159, females = 59) participating in team and individual sports completed life stress, resilience, coaches' social support, and athlete burnout scales. Hierarchical multiple regression analyses with one- two- and three-way interactions examined disjunctive and conjunctive moderations.ResultsResilience and coaches' social support conjunctively moderated the stress-burnout relationship. Specifically the interaction of athletes' resilience with coaches' informational and tangible social support moderated athletes' stress-burnout relationship in high and low life stress conditions.ConclusionsWe suggest coaches provide useful social support and foster athletes' resilience to prevent stress-induced burnout in athletes.     

Predicting change in middle school students’ leisure-time physical activity participation: A prospective test of the trans-contextual model

We applied the trans-contextual model (TCM) to examine the effects of middle school students’ perceived autonomy support from their physical education (PE) teachers on autonomous motivation toward PE in school and, critically, autonomous motivation toward, and actual participation in, leisure-time physical activity (PA). The research adopted a three-wave prospective design enabling the modeling of change in the TCM constructs over time. Middle school students (N = 248) aged from 12 to 16 years reported their perceived autonomy support, autonomous motivation in PE, autonomous motivation toward leisure-time PA, attitudes, subjective norms, perceived behavioral control (PBC), intentions for PA in leisure-time, and leisure-time PA participation. The psychological constructs and leisure-time PA were measured at baseline (T0) and at a first follow-up occasion (T1) 5 weeks later. Another measure of PA was taken at a second follow-up occasion (T2) a further 5 weeks later. A single-indicator structural equation model using residualized change scores revealed that perceived autonomy support predicted autonomous motivation in PE (β = .345), and autonomous motivation in PE predicted autonomous motivation for leisure-time PA (β = .484). Autonomous motivation toward leisure-time PA predicted attitudes (β = .425), subjective norms (β = .264), and PBC (β = .517). Autonomous motivation toward leisure-time PA (β = .376), attitude (β = .231), and subjective norms (β = .185) predicted intentions toward leisure-time PA, and intentions predicted PA (β = .198). Findings extend research on the TCM by demonstrating its efficacy in predicting change in middle school students’ autonomous motivation across PE and leisure-time contexts, and accounting for change in intentions toward, and actual participation in, leisure-time PA.     

Group cohesion and relatedness as predictors of self-determined motivation and burnout in adolescent female athletes

ObjectivesAthlete burnout is the result of a maladaptive sport experience that is influenced by the social context. A salient social contextual feature of youth sport is group cohesion. Cohesion may link with burnout through its association with relatedness and self-determined motivation. The current study was designed to test a model in which cohesion associates with burnout by way of relatedness and self-determined motivation.DesignCross-sectional survey-based study.MethodFemale youth soccer athletes (N = 276; M age = 14.9 years, SD = 1.3) completed measures of task and social cohesion, relatedness, self-determined motivation, and burnout.ResultsTask (β = 0.26) and social (β = 0.59) cohesion associated with perceptions of relatedness. In turn, relatedness positively linked with self-determined motivation (β = 0.38), which in turn negatively associated with global burnout (β = −0.79). The indirect effects from task cohesion to burnout (β = −0.08) and from social cohesion to burnout (β = −0.18) by way of relatedness and self-determined motivation were significant.ConclusionsResults support the proposed model whereby greater cohesion associates with an athlete’s feelings of relatedness, which links to more self-determined motivation and, consequently, lower burnout perceptions. Future research is needed to assess support for causality of these links and explore how contextual factors such as the teammate-created motivational climate contributes to group cohesion and relatedness perceptions within this burnout model.     

Using motivation regulations in a person-centered approach to examine the link between social physique anxiety in physical education and physical activity-related outcomes in adolescents

ObjectivesThis study explored how social physique anxiety (SPA) combined with different patterns of motivation regulations might facilitate versus deter effort and enjoyment in physical education (PE) and leisure-time physical activity.DesignCross-sectional survey.MethodsHigh school students (N = 298; M_age = 15.72, SD_age = 1.24 years) completed an in-class survey including SPA in PE, motivation regulations for PE, enjoyment and effort in PE and leisure-time physical activity.ResultsFour profiles of students were identified in cluster analysis based on autonomous motivation, introjected regulation, external regulation and SPA. Profile one (“high diverse motivation”; n = 84) reflected relatively high motivation across all regulations and average SPA. Profile two (“moderate autonomous motivation”; n = 92) included those with average scores on autonomous motivation and relatively low scores on introjected and external regulation and SPA. Profile three (“moderate diverse motivation and anxious”; n = 59) had relatively high SPA combined with average motivation regulations. Profile four (“externally controlled and anxious”; n = 63) also had relatively high SPA but relatively low autonomous motivation and introjected regulation and relatively high external regulation. MANOVA results showed that “externally controlled and anxious” students reported the lowest physical activity behavior and enjoyment in PE. Conversely, the “moderate diverse motivation and anxious” students have physical activity experiences that do not differ from the two profiles that exhibited lower SPA.ConclusionsHigher feelings of SPA in PE appear linked with lower levels of enjoyment and effort in PE and leisure-time physical activity outside of school only when coupled with higher external regulation. This finding helps explain inconsistent associations between SPA and physical activity outcomes.     

Social cognitive predictors of competitive level among athletes with physical disabilities

ObjectiveTo test a model of Social Cognitive Theory variables for predicting participation in higher versus lower levels of parasport competition. Information on modifiable factors associated with parasport competition would help parasport coaches and organizations transition recreational and developmental-level athletes to more competitive streams of participation.DesignCross-sectional survey.MethodParticipants were 95 parasport athletes with physical disabilities that cause mobility impairment (74% male; mean age = 34.36 ± 12.41). Measures of Social Cognitive Theory constructs were assessed via online questionnaires. Path analysis was used to test the proposed model.ResultsThe model explained 12% of the variance in level of sport participation. Peer support for sport was a significant predictor of self-regulatory efficacy (β = .22, p < .05) which, in turn, was positively related to outcome expectations (β = .43, p < .001), and self-regulation (β = .43, p < .001). Self-regulatory efficacy was the only significant predictor of level of sport participation (β = .26, p < .05). There were no significant indirect effects between social support and competitive status (p > .05).DiscussionSocial Cognitive Theory provides a reasonable basis for formulating a model of psychosocial factors related to parasport competitive status. Other relevant factors should be taken into consideration in subsequent studies. Parasport coaches and organizations may benefit from leveraging peer support to help bolster athletes' self-regulatory efficacy to levels conducive to participation in higher competitive sport streams.     

Memories of school recess predict physical activity enjoyment and social-emotional well-being in adults

School recess can provide social, emotional, and physical benefits for children. Yet, not all children experience recess the same, as inequity in access to recess and variability in the quality of recess exist. Researchers have yet to understand the long-term implications of recess experiences on adult well-being and physical activity behaviors. The purpose of this study was to explore the inter-relationships between memories of recess, physical activity, and social-emotional well-being. A total of 514 adults between the ages of 19 and 79 (M = 45.56; SD = 15.62) were surveyed via Prolific, a web-based research platform. Participants were asked about their memories of recess enjoyment and recess exclusion, and current physical activity levels, physical activity enjoyment, social isolation, social role satisfaction, and sense of meaning and purpose. Structural equation modeling analysis showed that memories of recess enjoyment were associated with meaning and purpose (β = 0.138, p < .05) and PA enjoyment (β = 0.183, p < .05). Furthermore, retrospective recess exclusion predicted current social isolation (β = 0.266, p < .05) and was negatively associated with retrospective recess enjoyment (β = −0.379, p < .05). Findings highlight the importance of childhood recess experiences and its impact on current physical activity behaviors, social isolation, and meaning and purpose later in life. Consistent with other research, early positive physical activity experiences, in the form of recess, appear to provide more assurances that one will engage in healthier lifestyle behaviors and more favorable psycho-socio-emotional profiles in adulthood.     

Effect of autonomy support and dialogic learning on school children’s physical activity and sport

This study applies an intervention based on autonomy support through dialogic learning to examine effects on motivation and the promotion of physical activity and sport involvement during schoolchildren’s leisure time. One hundred and two primary school students, aged 11–13 years, participated (M = 10.93, SD = 0.75). The sample was divided into two groups: an experimental group (49 students) and a control group (53 students). A quasi-experimental study was conducted in physical education classes over the course of 9 months. Assessments of autonomy support from teachers, family, and peers; basic psychological needs; self-determined motivation in physical education and during leisure time; planned behavior variables; physical activity intention; and estimated and actual physical exercise behavior time were included in the model. Following the intervention, the results revealed that greater autonomy support by the teacher, the family and peers, satisfaction of the basic psychological needs, self-determined motivation during physical education class and during free time, greater perceived control, favorable attitude and intention to engage in physical activity contributed to the explanation of student physical activity involvement. These results suggest that when students receive extensive social support from diverse social agents that essential precursors to physical activity are strengthened and contribute to increased motivation and actual physical activity involvement. Efforts to promote effective communications with students and other pedagogical efforts, such as providing dialogic learning opportunities, should be considered in order to strengthen physical activity motivation and involvement in students.     

Modeling indicators and outcomes of students’ perceived teacher relatedness support in high school physical education

Research based in self-determination theory has demonstrated the importance of social agents for motivational processes in school-based physical education (PE). To focus more closely on the relational processes that underpin students’ motivation in PE, there have been calls for researchers to explore the specific teacher behaviors that facilitate students’ relatedness in PE. Our aim was to test a higher-order measurement model comprising distinct relatedness-supportive teacher behaviors, and to explore the ways in which students’ perceptions about their teacher directly and/or indirectly predict relatedness need satisfaction and motivation in PE. To test our higher-order model (Study 1), 656 high-school PE students reported the extent to which their teachers engaged in relatedness-supportive behaviors. In Study 2, 570 high-school PE students reported their motivational regulations for PE, as well as the extent to which their teacher engaged in relatedness-supportive behaviors, and satisfied their need for relatedness. We found support for the higher-order relatedness support model, and observed predictive pathways that were consistent with theory. Students reported satisfaction of their need for relatedness when they felt relatedness support from their teachers (β = 0.52, p < 0.001) and relatedness need satisfaction was in turn positively related to intrinsic (β = 0.51, p < 0.001), identified (β = 0.49, p < 0.001), and introjected (β = 0.25, p < 0.001) regulations for PE. These findings demonstrate the importance of relatedness-supportive teaching in PE, and implications of these data are discussed.     

This Girl Can,can’t she? Perspectives from physical activity providers and participants on what factors influence participation

AimsThe present study used a multi-method approach to qualitatively explore whether the perceptions of young women and girls and exercise providers are aligned in terms of the factors that influence participation with the aim to better understand how these factors influence participation.DesignThematic analysis was used to synthesise focus groups and interview data within the intrapersonal, interpersonal, organisation, environmental, and policy levels of an ecological model.MethodsInterviews were conducted with 4 experienced exercise providers (2 men, 2 women). Focus groups were conducted with 21 young women and girls (M = 17.9, SD = 2.4) who had participated in one of the exercise interventions developed and delivered by the providers.ResultsThe perceptions of participants and providers were often disparate but revolved around the same themes especially at the intrapersonal and interpersonal levels. They expressed contrasting views regarding the importance of skill development and enjoyment, and the role of boys and instructors. At the organisational level, both participants and providers agreed that schools offer opportunities as well as barriers to engagement in physical activity and exercise. At the environmental level, urbanisation, safety, culture, and social media appeared as main themes where the perspectives of participants and providers complemented each other. Finally, at the policy level the main themes were derived from providers and concerned issues around programme funding. Participants provided valuable commentary about a nationwide campaign to promote physical activity to females.ConclusionsIn order to provide engaging physical activity and exercise for young women and girls it is necessary to align the needs and expectations of participants and providers at the intrapersonal and interpersonal levels. For sustainable exercise provision that impacts young women and girls, it is essential to align funding strategies and deliverables between exercise providers, local and national stakeholders.     

Physical activity participation and physical aggression in children and adolescents: A systematic review and meta-analysis

BackgroundAggressive behaviour is a substantial behavioural problem in children and adolescents. This review systematically summarises the current evidence on the relationship between physical activity participation and aggressive behaviour and quantifies the effects of physical activity interventions on aggression in children and adolescents.MethodsStudies were identified through a search of five electronic databases (PsycINFO, SPORTDiscus, MEDLINE, CINAHL and Web of Science) with combinations of three groups of keywords. Two independent reviewers screened and extracted data from the individual studies. The reporting quality and publication bias were assessed. The relationship between physical activity participation and aggressive behaviour was systematically summarized. Data (effect sizes) were pooled to investigate the effects of physical activity interventions on aggressive behaviour. A moderator meta-analysis was performed to identify potential moderators of the effects of physical activity interventions on aggressive behaviour.ResultsNineteen studies met the inclusion criteria. The relationship between physical activity participation and aggressive behaviour was mixed. A significant reduction in aggressive behaviour was observed after physical activity interventions (k = 8, SMD = −0.53, 95% CI [−0.27, −0.79], p < 0.001). The moderator meta-analysis showed that physical activity interventions involving team-based physical activity had greater effects than those involving individual-based physical activity (β = 0.42, SE = 0.18, p = 0.02). In addition, interventions involving physical activity alone were more effective in reducing aggressive behaviour than those that combined physical activity with other activities such as a philosophy course (β = −0.63, SE = 0.11, p < 0.001).ConclusionThe current meta-analysis presents evidence for the effect of physical activity interventions on aggressive behaviour in children and adolescents. Physical activity–only interventions involving team-based physical activity might be used for preventing or reducing aggressive behaviour in children and adolescents. Possible mechanisms, methodological strengths and weaknesses, implications, and suggestions for future studies were discussed.     

Life skills development in physical education: A self-determination theory-based investigation across the school term

ObjectivesGrounded in self-determination theory (SDT), the main aim of this study was to examine the longitudinal associations between teacher autonomy support, students’ basic psychological need satisfaction and life skills development in physical education (PE).DesignThis study employed a two-wave longitudinal research design.MethodStudents (N = 266, Mage = 12.94 years, SD = 0.70) completed measures assessing perceived autonomy-supportive teaching, need satisfaction (autonomy, competence, and relatedness), and life skills development in PE (teamwork, goal setting, social skills, problem solving and decision making, emotional skills, leadership, time management, and interpersonal communication). Data collections took place during week 6 (timepoint 1; T1) and week 15 (timepoint 2; T2) of the autumn school term.ResultsCross-lagged panel analyses showed that T1 teacher autonomy support did not significantly predict students’ three basic psychological needs, total need satisfaction or life skills development at T2. Students’ T1 total need satisfaction positively predicted their development of all eight life skills at T2. Additionally, students’ T1 autonomy satisfaction positively predicted their teamwork, social skills, emotional skills, leadership, and interpersonal communication skills at T2, T1 competence satisfaction positively predicted students’ teamwork skills at T2, and students’ T1 relatedness satisfaction positively predicted their social skills at T2.ConclusionsProviding partial support for SDT, the findings highlighted that satisfaction of students’ three basic psychological needs had some positive effects on students’ life skills development in PE. As such, a climate that satisfies students’ basic psychological needs should help to develop their life skills in PE.     

Depression severity and psychosocial determinants of physical activity behavior in in-patients with major depressive disorders

BackgroundPhysical inactivity is a world-wide health issue. In people with major depressive disorders approximately 68% do not reach the recommended physical activity levels. Psychosocial determinants of and implicit attitudes towards physical activity serve to explain physical activity behavior and may form the basis of interventions to promote physical activity. The aim of this study was to examine, whether psychosocial determinants and implicit attitudes towards physical activity vary according to depression severity.MethodsPhysically inactive, adult in-patients diagnosed with major depressive disorder (according to ICD-10) were recruited from four Swiss psychiatric clinics. Psychosocial determinants of physical activity were assessed with seven questionnaires pertaining to motivational and volitional aspects of physical activity. Implicit attitudes towards physical activity were measured with a computer-based Single Target Implicit Association Test.ResultsIn-patients (N = 215, M_age = 41 ± 13 years, 53% female) with major depressive disorder reporting more severe (n = 52) depression symptomology exhibited less favorable psychosocial determinants for physical activity behavior (self-efficacy, negative outcome expectancies, intention, intrinsic motivation, introjected motivation, external motivation, action planning, perceived barriers, coping planning) compared to those with mild (n = 89) and moderate (n = 74) depression symptomology. Positive outcome expectancies, identified, social support and implicit attitudes towards physical activity did not vary according to depression severity.ConclusionsPsychosocial determinants of physical activity do vary according to depression severity. Attempts to promote physical activity among people with major depressive disorder should take depression severity into account when developing and delivering interventions.Trial registrationISRCTN registry, ISRCTN10469580, registered on 3^rd September 2018, https://www.isrctn.com/ISRCTN10469580.     

Intervention-enabled autonomy-supportive teaching improves the PE classroom climate to reduce antisocial behavior

BackgroundAutonomy-supportive teaching interventions enhance PE student outcomes. According to previous research, these benefits occur because autonomy-supportive teaching enhances students’ psychological needs, though they may also occur because such teaching enhances the classroom climate. The student benefit of interest was reduced classroom-wide antisocial behavior.ObjectivesWe predicted that teacher participation in the intervention would enhance both classroom climate and psychological needs assessed at the classroom level. We further predicted that improvements in the classroom climate would better explain decreased antisocial behavior.MethodUsing a cluster randomized control trial design with longitudinally-assessed dependent measures, we randomly assigned 49 physical education secondary-grade Korean teachers to participate (or not) in an autonomy-supportive teaching intervention (25 experimental, 24 control). The 1487 students in these 49 classrooms reported their individually-experienced need satisfaction and frustration and their classroom-level supportive climate, conflictual climate, and antisocial behavior across three waves.ResultsA series of doubly latent multilevel structural equation modeling analyses showed that, at the classroom level, (1) intervention-enabled autonomy-supportive teaching improved both students’ psychological needs (more satisfaction, β = 0.84; less frustration, β = −0.66) and the prevailing classroom climate (more supportive, β = 0.77; less conflictual, β = −0.68) and (2) the improved climate best explained why antisocial behavior declined (overall R² = 0.86).ConclusionThese findings show the importance of incorporating classroom climate effects to understand why autonomy-supportive teaching interventions improve student outcomes.     

The TASS-Q: The Team-referent Availability of Social Support Questionnaire

ObjectivesTo provide initial evidence for the construct validity of the Team-referent Availability of Social Support Questionnaire (the TASS-Q).DesignCross-sectional in Study 1, and two time points in Study 2.MethodThe preliminary study required participants (N = 47) to assess the content validity—dimensional belonging, understanding, and relevance—of the TASS-Q items. In Study 1, participants (n = 336) completed the TASS-Q and measures of social desirability and negative affectivity. In Study 2, approximately one week before a competition (Day 1, Time 1) participants (n = 413) completed the TASS-Q; approximately 1 h before the same competition (Day 7–9, Time 2) participants completed measures of collective efficacy in relation to the impending competition and team cohesion.ResultsFollowing evidence for the scale content validity of the TASS-Q in the preliminary study, Study 1 provided support for the factor structure of the TASS-Q comprising emotional, esteem, informational, and tangible dimensions. Study 2 provided partial evidence for the factor structure of the TASS-Q and evidence of the criterion-related validity of the measure, demonstrating that (a) team-referent esteem support was a positive predictor of collective efficacy, (b) support dimensions, collectively, explained significant variance in task cohesion dimensions, and (c) emotional support was a positive predictor of social cohesion (group integration—social).ConclusionsThe article provides initial evidence for the construct validity of the TASS-Q and demonstrates, for team-referent social support, the theoretical advantages of examining a multidimensional conceptualisation of perceived availability of social support.     

Test–retest reliability of the Brunel Lifestyle Physical Activity Questionnaire

ObjectivesTo establish the test–retest reliability of planned physical activity (PPA) and unplanned physical activity (UPA) components of the Brunel Lifestyle Physical Activity Questionnaire (BLPAQ). To provide evidence of the BLPAQ's stability using the proportion of agreement (PoA) method over a 5-week period.DesignTest–retest over a 5-week period using three diverse samples of adults.MethodsThe 277 participants were subdivided into three adult samples: gymnasium users (n = 80), undergraduate students (n = 111), and university staff members (n = 86). They were asked to complete the test–retest measure in their places of exercise, study, or work respectively.ResultsCorrelation coefficients between test–retest administrations were calculated for each participant group and intraclass correlations were calculated for each item. Pearson's product-moment correlations ranged from r = 0.95 to r = 0.96 for the PPA subscale and r = 0.93 to r = 0.98 for the UPA subscale. Intraclass correlations ranged from R = 0.52 to R = 0.99 for PPA and R = 0.87 to R = 0.99 for UPA. Fisher's z tests indicated that the test–retest correlation coefficients for the BLPAQ subscales were, on the whole, significantly stronger than those of older, comparable subscales from lifestyle physical activity questionnaires. The PoA analysis for each item revealed that the test–retest administrations were in high agreement (>95%).ConclusionsOverall, the PPA and UPA factors of the BLPAQ demonstrated high reliability and stability. The present study also illustrates the utility of PoA analysis in establishing the stability of physical activity measures.     

Biological maturation and physical activity in adolescent British females: The roles of physical self-concept and perceived parental support

ObjectivesThis study examined the mediating and moderating effects of physical self-concept and parental support, respectively, on relations between maturation and physical activity (PA) in British adolescent females.DesignCross-sectional field based study.MethodsBiological maturity status, physical self-concept, perceived parental support for PA, and self-reported PA were assessed in 244 female British year 7–9 pupils (M age = 12.8 years, SD = .9).ResultsStructural equation modelling, employing maximum likelihood estimation and boot-strapping procedures supported the contention that physical self-concept mediated an inverse relation between maturation and PA. A regression model examining the main and interactive effects of maturation and parental support on PA provided evidence of a main effect for parental support, but no interactive effect.ConclusionsThe results suggest that physical self-concept partially mediates an inverse relation between maturity and physical activity in adolescent females. Accordingly, how adolescent females interpret or perceive the changes associated with maturation may be more important than maturation itself. Encouraging adolescent females to view puberty as a natural and attractive aspect of the process of ‘growing up’ may help mitigate any negative health consequences associated with early maturation. Parental support for PA does not appear to moderate relations between maturation and PA.     

Sources of autonomy support,subjective vitality and physical activity behaviour associated with participation in a lunchtime walking intervention for physically inactive adults

ObjectivesBased on Basic Needs Theory (BNT: Deci & Ryan, 1985), this study examined longitudinal relationships between autonomy support from two sources, psychological need satisfaction, subjective vitality and self-reported physical activity during a walking intervention for physically inactive adults. We proposed that autonomy support provided via a walk leader and the overall programme would independently predict change in subjective vitality and physical activity from baseline to week 16 (post-intervention) and at four month follow-up. Further, we proposed that direct relationships among sources of autonomy support and outcomes would be mediated by autonomy, relatedness, and competence need satisfaction.DesignA longitudinal examination.MethodsParticipants (N = 69; n = 63 females, n = 6 males) from a 16-week walking programme completed a multi-section questionnaire measuring the aforementioned variables at three time points, including a four month post-intervention follow-up.ResultsBoth hypotheses were partly supported. Autonomy support from the walk leader positively predicted changes in subjective vitality from baseline to week 16 and in physical activity from baseline to follow-up. Autonomy support from the programme positively predicted changes in subjective vitality from baseline to week 16. Finally, autonomy gained from the walk leader mediated the relationship between autonomy support and subjective vitality, and between perceived autonomy support and physical activity.ConclusionsFindings indicate that autonomy support from both a walk leader and wider programme can predict psychological need satisfaction, subjective vitality and physical activity. Clinicians and researchers implementing future walking interventions may increase physical activity and subjective vitality by facilitating psychological need satisfaction through autonomy support from both sources.     

Working memory,sustained attention,and physical activity: An intraindividual study

ObjectiveExperimental studies show small to moderate effects of both acute and regular physical activity on executive functions, these being strongly associated with academic performance at school. In order to understand the naturally occurring associations between primary school-aged children’s working memory, self-reported sustained attention, and physical activity, 35 children (M_age = 9.8 years, range = 7.6–11.4 years old) in Years 3–6 of primary school took part in a two-week long intraindividual study.MethodsParticipants wore an accelerometer wristband throughout the study, and carried out a working memory task (digit recall) and completed a sustained attention measure each morning and afternoon, giving 517 time-points nested in 4–10 school-days (M_obs = 15.8 situations, n_obs = 4–18).ResultsUsing multilevel structural equation models (MSEM), we found that working memory was stable across time (within-person b = 0.29) and trait-like (ICCs = 0.58). Across situations, state-working memory was higher later in the calendar week. Acute moderate to vigorous physical activity (MVPA) was not associated with state-working memory, but exertion of a higher level of MVPA than usual the previous day was associated with lower state-working memory the following day. Trait-sustained attention (across the two weeks) predicted higher trait-working memory and older students outperformed younger students.ConclusionsImplications for timing and intensity of students’ physical activity in educational settings is discussed.
