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.     

Youth sports and physical activity: The relationship between perceptions of childhood sport experience and adult exercise behavior

ObjectiveParticipation in organized youth sports has been shown to positively correlate with increased levels of exercise in adulthood. However, there is limited research to suggest why youth sports participation is related to increased physical activity as an adult. One possible explanation is that positive youth sport experiences lead youth to be more positively inclined to engage in physical activity as adults. Research into the positive youth development aspect of organized sports provides the framework for the current investigation.MethodsAdult participants (N = 234, M_age = 35.35) were asked to retrospectively assess their youth sports experiences using the “Four C's” (i.e., competence, confidence, connectedness, character) framework of positive youth development in sport. These assessments were then compared to current physical activity levels and related variables found in the Health Action Process Approach model (HAPA; Schwarzer, 2008).ResultsBivariate correlations revealed statistically significant and moderate correlations among competence, confidence, and connectedness and all of the HAPA variables including physical activity levels. Further, a MANCOVA analysis revealed that when participants were sub-divided into “non-intenders,” “intenders,” and “actors” using a validated staging algorithm, a general linear trend emerged for competence, confidence, and connectedness such that “non-intenders” rated these constructs the lowest and “actors” rated them the highest.ConclusionThese findings provide preliminary evidence that the relationship between participation in organized youth sports and adulthood levels of exercise could be contingent on how positively that experience is perceived.     

Developing physical activity interventions for youth with cystic fibrosis and congenital heart disease: Learning from their parents

Despite the benefits of physical activity for youth with cystic fibrosis (CF) and congenital heart disease (CHD), most are insufficiently active. More information is required on how to facilitate physical activity in these populations. Although there are no studies that provide information about participation in CF and CHD youth from the perspective of parents, the involvement of caregivers may be an important facilitator to physical activity in youth with chronic diseases.

Objective

This qualitative study explored how the parents of youth with CF and CHD experience physical activity, and parents commented on both their own and their child’s physical activity.

Methods

Twenty-nine parents from a CHD and CF clinic participated in a semi-structured interview, and a thematic analysis of the transcribed data was undertaken.

Results

Parents discussed the numerous benefits and barriers associated with physical activity for both child and self. Role modeling was a critical social process to overcoming barriers. Parents experiences were situated within the broader family context characterized by a prevailing sense of stress and complexity.

Conclusion

By illustrating how the parents of youth with CF and CHD understand the role of physical activity in their and their child’s life, this study provides valuable information regarding the development of interventions to increase physical activity among children with CF and CHD.     

Mediators of behavior change in two tailored physical activity interventions for adolescent girls

ObjectivesIt has been suggested that the lack of knowledge regarding the mechanisms responsible for behavior change may be responsible for the low levels of effectiveness in physical activity interventions among youth. While it is common for physical activity interventions to cite a theoretical framework, few test the validity of their constructs using an established mediation analysis technique. The purpose of this study was to identify mediators of physical activity behavior change in two tailored interventions for adolescent girls.DesignThis study involved an experimental design.MethodsParticipants (N=161) were randomly allocated to a control (CON) group, an intervention based on the Health Promotion (HP) Model or an intervention developed from the HP Model that included two processes from the Transtheoretical Model (THP). Both interventions included school-based education sessions, individual counseling sessions, and two physical activity sessions completed with the participants' mothers. Measures were assessed prior to the intervention, at post-intervention and at a 6-month follow-up. The following constructs were included in the mediation analyses: perceived benefits, perceived barriers, self-efficacy, exposure to models, social support, interpersonal norms, planning, stimulus control, and counterconditioning.ResultsPerceived benefits, perceived barriers, self-efficacy, and commitment to planning satisfied the criteria for mediation in the THP intervention. Self-efficacy and commitment to planning were identified as mediators in the HP intervention.ConclusionThe results of this study provide evidence that both interventions were successful in increasing physical activity through changes in the theoretical constructs.     

Coach autonomy support predicts autonomous motivation and daily moderate-to-vigorous physical activity and sedentary time in youth sport participants

ObjectiveGuided by self-determination theory (Deci & Ryan, 1987), this study tested a trans-contextual model linking perceptions of the social environment created by the youth sport coach to levels of autonomous and controlled motivation, and objectively measured daily moderate-to-vigorous physical activity (MVPA) and sedentary time (ST) in young football players.DesignThe study employed a cross-sectional design, assessing physical activity using accelerometers.Method105 male youth sport footballers (M age = 12.79 ± 1.85 years) wore a GT3X accelerometer for 7 days. Measures of height and weight were recorded. Participants completed a multi-section questionnaire assessing perceptions of autonomy support and controlling coaching behaviours, and motivation toward their participation in sport and physically active games.ResultsPath analysis supported a model in which players’ perceptions of coach-provided autonomy support positively predicted autonomous motivation for sport engagement. In turn, autonomous motivation was positively associated with MVPA, and negatively related to ST (min/day). Controlling coach behaviours were positively linked to controlled motivation. However, controlled motivation for sport and physically active games was unrelated to daily MVPA and ST. Perceptions of coach-provided autonomy support had a significant positive indirect effect on daily MVPA, and a significant negative indirect effect on daily ST.ConclusionsResults suggest that autonomy supportive coach behaviours are related to daily physical activity patterns in young male footballers. Theory-based interventions that aim to encourage autonomy supportive coaching, and subsequently foster autonomous reasons for sport engagement, may enhance the potential of youth sport for increasing daily MVPA and reducing ST among children and adolescents active in this setting     

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.     

Attachment relationships and physical activity in adolescents: The mediation role of physical self-concept

ObjectivesBased on the integration of attachment and physical self-perception perspectives, the present study examined links between adolescents' engagement in physical activity and their attachment relationships with mothers, fathers, and friends, respectively, and assessed the potential mediation role of physical self-perception in this link.Design and methodsUsing a cross-sectional design, questionnaire data was obtained from 767 adolescents (49% boys, M_age = 12.92, SD = .86) and structural equation modeling was used to examine relationships among variables.ResultsAttachment security with parents and friend was associated with higher levels of physical activity. There was partial support of the mediation role of physical self-perception, as adolescents who were securely attached to mother and friend perceived themselves as having better physical condition, which in turn predicted greater engagement in physical activity. The mediation role of physical self-perception between mother attachment and PA was stronger for female adolescents. Secure attachment to father had a direct positive effect on physical activity. The direct effect was strongest for male adolescents.ConclusionsOur findings highlight the importance of relationship-based intervention strategies to enhance and maintain healthy regular physical activity among adolescents.     

Attributions for physical activity in very old adults: predicting everyday physical activity and mortality risk

Objectives: Although physical activity is recognised as a health-promoting behaviour for older adults, notable barriers exist that may reduce physical activity in this age group. Limited research has explored causal beliefs (attributions) as a barrier to physical activity. Our study assessed associations between older adults’ attributions about physical activity and objective health outcomes. Methods: We examined the role of attributions as a predictor of everyday physical activity (EPA) and subsequent mortality risk over a 10-year period (2006–2016) in a sample of older adults (M_age?=?87, N?=?261). Results: OLS and Cox proportional hazard regression analyses revealed older adults who endorsed more internal and uncontrollable attributions for limited activity (physical incapacity) when feeling unwell had lower subsequent EPA (β?=??0.18), and higher 10-year mortality risk (HR?=?1.46). Other attributions with different dimensional properties (e.g. internal and controllable) were not associated with EPA or mortality. Discussion: Findings suggest that causal beliefs older adults have about their physical activity can influence their future behaviour and longevity. Psychological treatments designed to discourage maladaptive attributional thinking for older populations who face barriers to physical activity may be an important avenue for future research.     

Elementary schoolchildren's perceived competence and physical activity involvement: the influence of parents' role modelling behaviours and perceptions of their child's competence

ObjectivesTo study the influence of fathers' and mothers' physical activity involvement and perceptions of their children's physical competence upon children's perceptions of competence and children's time spent in physical activity. Two forms of parental socialization influence were assessed: the direct influence of parents' actual physical activity (PA) behaviour (role modelling) on children's physical activity and the indirect influence of parents' beliefs systems about their children's PA competence on children's physical activity through children's self perceptions.MethodsLongitudinal, with data from 152 French children (M=9.5 yrs, SD=0.8 yrs) and their parents collected at two times over a 12-month period and examined through structural equation modelling (SEM).ResultsSEM indicated that mothers' role modelling behaviour had a direct effect on children's time spent in PA and that mothers' beliefs about their child's competence had an indirect effect on children's PA by influencing children's perceived competence which, in turn, contributed to children's level of physical activity involvement. Fathers' beliefs directly influenced their child's PA as did the children's own self-perceptions of competence.ConclusionsParents can affect their children's PA involvement in direct and indirect manners through their role modelling of physical activity and through their beliefs about their child's competence. Furthermore, the influence of fathers and mothers may be manifested in different ways. Father and mother could influence their child's PA by different processes.     

A systematic review of the within-person association between physical activity and affect in children's and adolescents' daily lives

BackgroundIt is important to understand the relationship between physical activity and affect because affect experienced during physical activity and momentary incidental affect may both predict physical activity behaviours. Additionally, affect experienced during physical activity may explain the mental health benefits of participation in physical activity. Utilising ambulatory assessment techniques, researchers can examine the acute within-person association between physical activity and affect in children and adolescents' daily life. The purpose of this study was to systematically review the literature to determine whether there is a within-person association between physical activity and affect in children and adolescents' daily life.MethodsMedline via EBSCOHost, SPORTdiscus, PsychINFO, and Scopus were searched up to March 2020. A narrative synthesis was used to summarize results of the included studies.ResultsTen studies, reporting on nine unique samples, met the inclusion criteria. The strongest evidence identified was for a positive within-person association between physical activity and subsequent positive affect and energy. The findings regarding the within-person association between physical activity and subsequent negative affect and moods were mixed, as were the findings regarding affect predicting subsequent physical activity.ConclusionThere was mixed support for the acute within-person association between physical activity and affect in children and adolescents. Future research should consider factors that may moderate the relationship between physical activity and affect. Additionally, experimental research should examine how manipulations of incidental affect effect physical activity participation in children and adolescents' daily life.Prospero RegistrationCRD42020141649.     

Parent’s physical literacy enhances children’s values towards physical activity: A serial mediation model

PurposePhysical literacy is a multidimensional concept that concerns the affective, physical, cognitive, and behavioural aspects of physical activity (PA). It plays a vital role in enhancing PA engagement. However, current research on physical literacy’s function in the family setting is scarce. Its potential effect in elevating values towards PA among parents and children is also understudied. In this study, we examined the predicting role of parents’ physical literacy on children’s values towards PA. We also explored the potential mediating roles of parents’ values towards PA and children’s perceived parental autonomy support for PA through a serial mediation model.MethodsA cross-sectional study was conducted between September 2020 and January 2021, a total of 946 primary school-age children (6–13 years) and their parents from 30 Hong Kong primary schools were recruited by cluster sampling method. Structural equation modelling analysis was conducted using Mplus 7.3.ResultsParents’ values towards PA and children’s perceived parental autonomy support for PA serially mediated between parents’ physical literacy and children’s values towards PA. Specifically, the indirect effects from parents’ physical literacy to children’s values towards PA via parents’ values towards PA (β = 0.12, 95% CI [0.06, 0.17]), and via parents’ values towards PA to children’s perceived parental autonomy support for PA (β = 0.05, 95% CI [0.02, 0.08]) were significant.ConclusionsParents’ physical literacy is a predictor of children’s values towards PA. Parental autonomy support may facilitate the intergenerational transmission of values towards PA between parents and children. Concurrent interventions that target enhancing parents’ physical literacy and parental autonomy support for PA in the family context may be more effective in raising children’s PA values.     

Psychological mechanisms underlying the relationship between commercial physical activity app use and physical activity engagement

PurposePrevious studies have indicated a relationship between the use of commercial physical activity apps (e.g., Fitbit, Strava) and physical activity engagement. The use of social components of such apps, in particular app-specific communities (connecting with other app users) and existing social networking platforms (e.g., Facebook) have the potential to enhance physical activity. This study aimed to explore the psychological mechanisms underlying the relationship between the use of commercial physical activity apps (and their social components) and physical activity engagement.MethodAn online cross-sectional survey assessed physical activity, use of commercial physical activity apps (and their associated social components), and psychological constructs (social support, self-efficacy, motivation, trait competitiveness, trait social comparison).Results1274 adults aged 18–83 years (M_age = 34.1 ± 13.5 years, 87.6% female) participated. App use was positively associated with physical activity engagement. The relationship between app use and physical activity was fully mediated by social support, self-efficacy, intrinsic motivation and identified regulation. Trait competitiveness, but not trait social comparison, moderated the relationship between app use and physical activity. Most features (e.g., sharing posts, providing or receiving encouragement) of the social components of apps were positively associated with psychological constructs linked to engagement in physical activity. Mediation pathways linking features of existing social networking platforms with physical activity were found. Specifically, sharing posts was linked to higher engagement in physical activity via positive associations with self-efficacy, and receiving encouragement with linked to higher engagement in physical activity via positive associations with both self-efficacy and identified regulation. In addition, engagement in comparisons was associated with lower self-efficacy and higher external regulation, and in turn, lower physical activity.ConclusionsThe relationship between the use of commercial physical activity apps and physical activity is underpinned by social support, self-efficacy and autonomous motivations. The findings highlight the importance of trait competitiveness, which should be taken into consideration when leveraging physical activity apps. Overall, the present study demonstrated that commercial physical activity apps (and their social components) hold great potential to increase physical activity engagement given their associations with psychological constructs strongly linked with physical activity.     

Reciprocal relationships between three aspects of physical self-concept,vigorous physical activity,and lung function: A longitudinal study among late adolescents

ObjectivesThis prospective study, of older adolescents, investigated relationships between three aspects of physical self-concept, vigorous physical activity and lung function. In particular, physical competence, general appearance evaluations and body areas satisfaction were expected to predict subsequent physical activity, which, in turn, was expected to explain variation in lung function. In line with the reciprocal effect model, bi-directorial relationships were also tested. Gender was expected to moderate hypothesized relationships.DesignA longitudinal design, with three measurement points (baseline, 2-month follow-up, and 14-month follow-up) was employed.Method551 late adolescents (15–18 years old) provided self-reported data on physical activity, physical competence, body areas satisfaction, and appearance evaluation. Body weight, height, and a lung function index (forced expiratory volume in 1 s, FEV₁) were measured at baseline and at the 14-month follow-up.ResultsModerated mediation analyses indicated that physical competence at baseline predicted vigorous physical activity (2-month follow-up) among young men and women. Baseline body satisfaction and appearance evaluation were also related to vigorous physical activity (2-month follow-up) and this relationship was stronger for men. Vigorous physical activity predicted FEV₁ (14-month follow-up) and this relationship was stronger among women. The reciprocal pattern of relationships was not confirmed.ConclusionsFindings suggest that health promoting interventions should focus particularly on vigorous physical activity among young women, for example by boosting their physical competence.     

Reciprocal effects of motivation in physical education and self-reported physical activity

ObjectivesThe present study tested whether self-reported school and leisure-time physical activity have a reciprocal relationship with Physical Education (PE)-based motivational regulations described by self-determination theory. Participants were 635 11- and 12-year-old school children from the United Kingdom.Design & MethodA cross-lagged longitudinal design over two time points was employed. Study hypotheses were analyzed using latent factor reciprocal effects models.ResultsFollowing temporal invariance tests, data revealed positive relationships between both types of physical activity and subsequent changes in autonomous motivation, but not the oft-stated reverse relationship. No relationships were observed involving introjected regulation. Theoretically aligned relationships between external regulation and changes in physical activity were observed, but no reverse relationships. Both types of physical activity behavior were negatively associated with changes in amotivation in PE, but surprisingly, amotivation in PE positively predicted changes in leisure-time physical activity.ConclusionsIn general, physical activity participation may help children internalize reasons for partaking in PE and foster self-determination. However, the widespread theory that self-determined PE motives can develop school and leisure-time physical activity participation was not compellingly demonstrated.     

Need fulfillment and motivation in physical education predict trajectories of change in leisure-time physical activity in early adolescence

ObjectivesWe examined (1) how psychological need fulfillment and motivation in physical education and leisure-time physical activity change during early adolescence, and (2) the degree to which need fulfillment and motivation predict trajectories of change in physical activity.DesignLongitudinal survey.MethodsStudents (N = 134, ages 10–13 years) completed surveys assessing perceived competence, autonomy, relatedness, intrinsic motivation, and identified, introjected, and external regulations in physical education, and leisure time physical activity each semester in school for 3 years.ResultsUnconditional growth models showed an average increase in physical activity. Competence also increased, while autonomy and relatedness, and identified and introjected regulation decreased. Conditional models showed that students with higher levels of autonomy, relatedness, intrinsic motivation, and identified regulation had higher levels of physical activity at baseline and throughout the study. Students with lower levels of autonomy, relatedness, intrinsic motivation, and identified regulation experienced significantly greater increases in physical activity, but these effects were very small.ConclusionsNeed fulfillment and motivation variables positively predict physical activity. While youth with lower levels of need fulfillment and motivation have lower levels of physical activity, they also tend to increase physical activity levels more across early adolescence. These associations highlight how physical education experiences in early adolescence may influence change in physical activity, and suggest efforts to foster need fulfillment and autonomous regulation in physical education may promote physical activity.     

Does parental support moderate the effect of children's motivation and self-efficacy on physical activity and sedentary behaviour?

Objectives1) To test whether parental support moderates the direct effects of children's motivation and self-efficacy on objectively measured moderate-vigorous physical activity (MVPA) and sedentary time. 2) To explore differences in the relationships between boys and girls.DesignCross-sectional observational study.MethodData were collected from 430 9–11 year old UK children and their parents; parents self-reported on the support they provided to their children to be active (through providing transport, encouragement, watching, or taking part with their child), and children self-reported their motivation and self-efficacy towards exercise. MVPA and sedentary time were measured using accelerometers.ResultsBoth parent- and child-level factors were largely positively associated with children's MVPA and negatively related to sedentary time. There was no evidence of a moderation effect of parental support on MVPA or sedentary time in boys. Parental provision of transport moderated the effect of girls' motivation on week-day MVPA; more motivated girls were less active when transport was provided. Transport and exercising with one's child moderated the effect of motivation and self-efficacy on girls' sedentary time at weekends; more motivated girls, and those with higher self-efficacy were less sedentary when parents provided more frequent transportation or took part in physical activity with them.ConclusionsThe results largely supported a model of the independent effects of parent and child determinants for moderate-to-vigorous physical activity, but there was evidence that some types of parent support can moderate sedentary time in girls. Further research is needed to explore the causal pathways between the observed cross-sectional results.     

Social cognitions measured in 4 to 6 year olds are predictive of objectively measured physical activity

Objective: This study tested whether social cognitions from the reasoned action approach (RAA) can be reliably measured in a sample of primary school children (aged 4–6 years) and whether these RAA measures are predictive of physical activity.

Design: Longitudinal observational study with repeated measures over six months.

Measures: RAA variables were measured using a novel choice paradigm between physically active and sedentary pastimes. Relative reinforcing value, covariates (sex, age, deprivation and BMI) and physical activity by accelerometry (primary outcome) were also measured.

Results: RAA cognitions could be measured with acceptable retest reliability and discriminant validity and social norms regarding parents and teachers (but not friends) were correlated with physical activity and change in physical activity when relative reinforcing value and other covariates were controlled for.

Conclusions: RAA cognitions can be reliably measured in primary school children aged 4–6 and RRA measures appear useful in understanding children’s activity choices and may potentially inform future interventions.     

Child's Physical Activity Lapses: Parents' Intended Use of Social Control1

This study explored parents' intention to use social control following a hypothetical lapse in their child's activity. Also examined was the role of parent and child activity as predictors of parental social control use. Parents (N = 140) were presented with 2 activity lapse vignettes (health consequences and no health consequences) and reported their intention to use social control after reading each. Results revealed greater parental intention to use social control following the health‐consequences lapse. Active parents reported greater intentions of using positive and collaborative social control tactics. Findings provide preliminary evidence that parents, especially those who are active, may attempt to regulate their child's activity following a failure to engage in a health‐enhancing behavior (i.e., lapse in physical activity).     

Parenting in youth tennis: Understanding and enhancing children's experiences

ObjectiveThe overall purpose of this study was to develop a grounded theory of optimal parental involvement in youth tennis.DesignA Straussian grounded theory methodology (Corbin and Strauss, 2008, Strauss and Corbin, 1998) was used. Semi-structured interviews and focus groups were conducted with 90 youth tennis players, ex-youth players, parents, and coaches from the United Kingdom. Data were analyzed through a process of open and axial coding, and theoretical integration. Through this process data were broken down into smaller units (concepts), relationships between concepts were identified, and a substantive grounded theory was developed.ResultsThe grounded theory of optimal parental involvement in tennis was built around the core category of ‘understanding and enhancing your child's tennis journey.’ The core category was underpinned by three categories: (a) Share and communicate goals, which referred to the need for parents and children to have the same aims for the child's tennis involvement; (b) develop an understanding emotional climate, which accounted for the need for parents to continually seek to foster an environment in which children perceived parents understand their experience, and; (c) engage in enhancing parenting practices at competitions, which denoted the specific behaviors parents should display in relation to competitive tennis.ConclusionThe theory predicts that consistency between goals, emotional climate, and parenting practices will optimize parenting in youth tennis.
