Towards consensus in conceptualizing and operationalizing physical activity maintenance

Recognized challenges in promoting long-term physical activity maintenance may be due to inconsistencies in the conceptualization and operationalization of behavior maintenance terminology in physical activity research. The overall goal of this paper is to propose a framework and agenda for the development of a common set of terms, definitions, and measures for physical activity maintenance concepts that can be widely tested and evaluated. To initiate this effort, this paper (1) provides an overview of conceptual and operational definitions of physical activity maintenance used in the empirical literature, (2) evaluates whether behavior maintenance terms used in addiction science can be translated to physical activity, (3) recommends research directions for developing consensus definitions of physical activity maintenance, and (4) proposes a conceptual model of physical activity maintenance with inflection points that require operational definitions to be decided upon through consensus efforts in the field. Consensus over the conceptualization and operationalization of physical activity maintenance is needed to draw conclusions regarding which policies and programs are best able to promote long-term behavior change.     

Peer relationships in physical activity contexts: a road less traveled in youth sport and exercise psychology research

Background and Purpose. While it is well established that social agents contribute to the quality of youth physical activity experiences, relatively little research has specifically explored peer relationships in physical activity settings. Rather, the bulk of research on social agents has focused on teachers, coaches, and parents. The purpose of this paper is to provide justification for pursuing youth peer relationships research and present conceptual and methodological issues of relevance to such efforts.Methods. The existing literature base on peer relationships in physical activity contexts is overviewed, emphasizing the contribution of peers to self-perceptions, moral attitudes and behaviors, affect, and motivation.Results and Conclusions. Promising future research directions are forwarded, focusing on (a) the possible contribution of peer relationships research to understanding self-presentational processes and developmental transitions, (b) the importance of examining the interaction of peer relationships and other social relationships in the physical activity context, and (c) the value of using the physical activity setting to promote quality peer relationships.     

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.     

Psychosocial mediators of group cohesion on physical activity intention of older adults

Considerable evidence has indicated that group-based physical activity may be a promising approach to reducing and preventing age-related illness. However, this research has not examined the mechanisms by which cohesion may impact on behaviour. The purpose of the present research was to utilise the theory of planned behaviour to investigate the mechanism by which group cohesion may affect physical activity intention. Participants were recruited from an existing physical activity intervention studying the effects of group cohesion on physical activity behaviour. The outcomes of this intervention are reported elsewhere. This paper presents data from a sub-sample of the intervention population (N=74) that examined the mediating relationships between the theory of planned behaviour and group cohesion on physical activity intention. Analyses showed that attitude and perceived behavioural control mediated the relationship between specific group cohesion concepts and physical activity intention. The direct measure of subjective norm failed to display a mediating relationship. The mediating relationships displayed between attitude and perceived behavioural control and physical activity intention provide insight into potential mechanisms by which group cohesion may affect behaviour.     

Toward a comprehensive model of physical activity

Background and purpose. Despite the widely acknowledged public health burden and years of individually based intervention approaches, physical inactivity remains a growing concern among industrialized nations. Interventions aimed at changing individual dispositions that increase physical activity generally result in small changes in behavior that dissipate within weeks. Correlational research testing theories and models focusing on these same individual dispositions explain, at best, 20–40% of the variance in physical activity. As a result, recent calls have been made for consideration of broader, multilevel, ecological approaches to physical activity promotion. The purpose of this article is to define a comprehensive model for understanding physical activity and consider future directions for research.Methods. Relevant literature is reviewed within each of the areas being discussed.Results and conclusions. Ecological models incorporate both intra- and extra-individual influences that may impact on individual physical activity. However, the role of extra-individual factors has not been clearly defined in current ecological models of physical activity. We present the theoretical background of ecological models of health behavior, and define an ecological model for physical activity promotion. This model portrays physical activity behavior as being influenced by interplay between environmental settings and biological and psychological factors. Further testing of this and existing ecological models of physical activity is recommended.     

Quality of Life Assessment for Physical Activity and Health Promotion

Despite the clear relationship of physical activity and quality of life (QoL), QoL measures are seldom targeted for physical activity and health promotion. The current research attempted to address that gap by developing a QoL measure based on a conceptual model that reflects positive health and is relevant for physical activity and health promotion programs. In the project, which extended over three phases, an initial 70-item QoL survey was administered to university students and community program participants (total n = 512) along with measures of satisfaction with life and physical activity. Exploratory and confirmatory factor analyses revealed clear social, emotional, cognitive, physical, spiritual and functional (ADL) QoL factors as well as integrated QoL. The resulting 32-item QoL Survey fits the conceptual model, demonstrates logical relationships with physical activity and has sufficient psychometric properties for use in related research and health promotion programs.     

Beliefs about age-related changes in physical functioning across the adult life span and their relationship with physical activity levels of older adults

Physical activity declines across the adult life span despite the well-established links between physical activity and health-related, psychological, cognitive, and social benefits. We contrasted the beliefs young and older adults hold about how aging affects both physical abilities and physical activity and determined whether older adults’ beliefs about physical aging relate to their engagement in physical activity. Using visual rating scales, 56 young and 49 community-dwelling older adults indicated the extent to which a typical woman or typical man aged 20–90 possesses six different physical abilities and engages in three different types of physical activity. Stereotypes of physical aging were ability- and activity-specific, and older adults endorsed more positive views than their younger peers. Stereotypical beliefs predicted older adults’ engagement in moderate-intensity activity. This study offers intriguing avenues for future research and suggests that better understanding physical aging stereotypes may contribute toward designing interventions that promote lifelong physical activity.     

A test of the impact of pain on automatic motivational processes in people with knee osteoarthritis

ObjectivePeople with osteoarthritis are likely to be physically inactive and current socio-cognitive approaches to changing physical activity in this patient population are generally ineffective. We assessed prospective associations between physical activity and the automatic processes of habit automaticity, automatic evaluations, and automatic self-schema in people with knee osteoarthritis.DesignOne-week prospective.Method253 adults (aged 46–82 years, 72% female, 28% male) with knee osteoarthritis self-reported their physical activity behaviour of the past week, habit automaticity for physical activity and completed two implicit association tests to assess automatic evaluations of physical activity (relative to sedentary behaviour) and automatic self-schema for physical activity. One week later, participants self-reported physical activity and pain while walking over the prior week. Linear regression models assessed associations of each automatic process with subsequent physical activity and the moderation effect of pain and each automatic process on subsequent physical activity, controlling for covariates.ResultsWe did not find evidence of a statistical relationship between physical activity with automatic evaluations, automatic self-schema, or habit automaticity. The inclusion of pain while walking did not moderate the relationship between any automatic process and physical activity.ConclusionAlthough previous research on healthy, young adults suggests that automatic processes affect physical activity behaviour, we did not find evidence to confirm whether a similar relationship exists for older adults with knee osteoarthritis. Replication and extension work testing these research questions is needed to ensure the findings are not a result of measurement and design features of the study.     

Mediating relationship between body mass index and the direct measures of the Theory of Planned Behaviour on physical activity intention

This research examines (a) the interrelationships between body mass index (BMI), the direct measures of the Theory of Planned Behaviour (TPB) and physical activity intention and (b) the potential mediation effects of the direct measures of the TPB in the relationship between BMI and physical activity intention in a sample of Australian adults. A total sample of 1,062 respondents participated in a computer-assisted telephone-interview (CATI) survey comprised of a standardised introduction; questions regarding TPB and physical activity; and standard demographic questions. BMI for each participant was calculated from self-reported height and weight. Separate regression analyses were performed to examine the mediating effects of each of the direct measures of the TPB on the predictive relationship between the BMI and physical activity intention, as proposed by Baron and Kenny (Journal of Personality and Social Psychology, 51(6), 1173 - 1182, 1986). Findings indicated that the direct measure of attitude and perceived behavioural control mediated the relationship between BMI and physical activity intention. However, the direct measure of subjective norm failed to act as a mediating mechanism. To date there has been no research that has examined the mechanism by which body mass may affect physical activity behaviour. Given the current focus for health promotion specialists on promoting physical activity as a strategy for reducing overweight and obesity, a theoretical understanding of weight-related barriers to physical activity may aid in the development of future interventions and community physical activity programs, particularly those targeting overweight and obese populations.     

Physical Activity,Suicide Risk Factors,and Suicidal Ideation in a Veteran Sample

The association between current level of suicidal ideation and physical activity was tested in a broad sample of veterans seeking care from the Veterans Health Administration. It was hypothesized that the two variables would be significantly inversely related. It was further hypothesized that the relationship would be mediated by depressive symptoms, disturbed sleep, and a measure of heart rate variability based on existing research regarding physical activity and sleep. Due to the first hypothesis not being supported, the second could not be tested. Post hoc correlation analyses did find associations between physical activity and depressive symptoms, in expected directions, and are discussed. Possible explanations for the negative findings along with recommendations for future research to continue exploring links between suicide risk and physical activity are presented. We conclude by suggesting that physical activity may have promise as a risk reduction intervention and that prospective data are more likely to yield significant results than the cross‐sectional methodology employed in the current study.     

Evaluation of physical activity measured via accelerometry in rural fourth-grade children

Interest in the benefits of exercise has prompted increased research examining the relationship between physical activity and health status in adults. More recently, considerable research effort has been directed toward the role of physical activity in young children as a precursor to adult physical fitness. The purpose of this study was to estimate the relationship between physical activity measured via accelerometry and body mass index, body mass, body composition, and physical fitness in fourth-grade boys and girls during physical education lessons. 54 fourth-grade students in rural Pennsylvania (28 girls, M age 9.6, SD = .56; 26 boys, M age 9.5, SD = .51) were subjects. Girls were significantly less active during all lessons measured (p < .001). The results of linear regression analyses indicated that physical activity was negatively associated with body mass index, body mass, and body fat percentage (p < .05), and positively associated with physical fitness (VO2max) (p < .01). These data indicate the need for curricular intervention to motivate girls to increase their activity during structured physical education lessons and demonstrate the efficacy of the body mass index as a screening tool within the schools.     

Flow in youth sport,physical activity,and physical education: A systematic review

Flow in sport, physical activity, and physical education can have widespread benefits for youth participants. The aim of this study was to systematically review, synthesise, and appraise literature on flow in youth sport, physical activity, and physical education. More specifically, the review explored the: methods used to study flow; conceptualisation of flow; antecedents associated with flow; interventions and mechanisms to facilitate flow states; and outcomes associated with flow. Electronic database and manual searches in September 2020 yielded 2,292 potential papers. Overall, 39 studies with 17,123 youths published over 36 years (1984–2020) satisfied the eligibility criteria and were included in the review. As the first systematic review of flow in physical activity contexts specifically in youth-aged participants, the synthesis identified several issues with the measurement and conceptualisation of flow. While evidence has accumulated on antecedents and outcomes of flow in youth sport, physical activity, and physical education, the reliance on cross-sectional designs prevents the inference of causality. Interventions designed to facilitate more frequent or intense flow experiences have been relatively unsuccessful, thus suggesting that further research is required to explain the occurrence of flow and to develop interventions that reliably induce flow states in youths. Overall, the review highlights a need for higher quality research to make meaningful progress in understanding of the flow experience in youth sport, physical activity, and physical education. Recommendations for future research that could help to advance understanding include: experimental studies; evidence-based flow interventions; and qualitative methods, such as event-focused interviews.     

A daily process analysis of physical activity,sedentary behavior,and perceived cognitive abilities

ObjectivesThis study evaluated the role of both physical activity and sedentary behavior in daily perceptions of cognitive abilities and whether these relations exist within-person, between-person, or both.DesignNon-experimental, intensive longitudinal research using ecological momentary assessments.MethodCollege students wore accelerometers and provided end-of-day reports on physical activity, sedentary behavior, and perceived cognitive abilities for 14 days.ResultsAcross self-reports and objective measures of behavior, daily deviations in physical activity were positively associated with perceived cognitive abilities. Daily deviations in self-reported, but not objectively-assessed, sedentary behavior also were negatively associated with perceived cognitive abilities. Contrary to previous research, overall levels of physical activity and sedentary behaviors were not associated with perceived cognitive abilities.ConclusionsThese findings indicate that physical activity has a within- rather than between-person association with perceived cognitive abilities although between-person associations effects may require longer monitoring periods to manifest. Further research is needed to establish the direction of causality and resolve whether the nature (rather than quantity) of sedentary activities influences cognition.     

Perceived activity and functional capacity in a rural elderly population.

Efficacy of guided self-help behavioural activation and physical activity for depression: a randomized controlled trial

Behavioural activation and physical activity have received empirical support that highlight their efficacy in reducing depression. Even though both behavioural activation and physical activity share the common goal of reactivating the individual, limited research has directly compared these interventions, and more research is required to evaluate their efficacy when offered in low-intensity formats. The present study involves a randomized controlled clinical trial comparing the efficacy of two guided self-help interventions for the treatment of depression: behavioural activation and physical activity. Fifty-nine participants presenting mild-to-moderate symptoms of depression were randomized either to a behavioural activation intervention (n = 20), a physical activity intervention (n = 19) or a wait-list control group (n = 20). All participants completed symptom measure pre-, mid- and post-intervention, as well as at a two-month follow-up. Mixed-model analyses of variance revealed that both interventions were significantly more efficacious in reducing depressive symptoms in comparison with the control group. Physical activity involved significantly less time-investment compared to the behavioural activation condition (less than half the amount of time). These results indicate that physical activity and behavioural activation both effectively reduce depressive symptoms and are favourably applicable in low-intensity formats. Implications of these results and avenues for future research are discussed.     

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.

Technology’s influence on physical activity and exercise science: the present and the future

Background and purpose. Research and application in the physical activity and exercise area are increasingly impacted by technology. The exponential growth of World Wide Web access and the proliferation of personal computers highlight the importance of this development. The purpose of this article is to discuss the current impact of technology on different aspects of physical activity interventions and potential future applications.Methods. Relevant literature is reviewed within each of the areas being discussed.Results and conclusions. Technology has contributed to a secular decline in physical activity; however, it allows a) the proactive recruitment of large populations, b) the individualization of interventions on a large scale, and c) the delivery of activity promoting interventions to large populations via differing channels. Support is emerging for individualized interactive physical activity interventions delivered to large samples. Yet-untested areas where technology may have a beneficial impact on physical activity adoption and maintenance are interactive TV and virtual reality. With the increased focus on environmental strategies, technology could also be used to modify home environments to facilitate incorporating physical activity into everyday life. Technology is also increasing its role in the business of physical activity/exercise. For example, web-based health sites are now listed on the stock market. Health and fitness centers are adopting high-tech entertainment capabilities to serve each client. Combining the individualized technology used in the adoption and maintenance research with the existing infrastructures in health and fitness centers could increase adherence within these centers. Currently, however, there is limited research and utilization of this technology for the promotion of physical activity and exercise at the population level.     

Alteration of mood state after a single bout of noncompetitive and competitive exercise programs.

This study evaluated the effects of three popular physical activities on the psychological well-being of university students. 44 students in three physical activity classes enrolled in the Fitness for Life Program at Montana State University which included circuit training, weight training, and racquetball were administered the Profile of Mood States scale 5 min. before and 5 min. after one bout of physical activity. Two of the three activities appeared to be associated positively with scores on certain subscales. The results supported positive psychological well-being of students after physical activity. Implications for research are presented.     

Seek,and You Will Find: The Influence of Expectations on Evaluations of Physical Activity

Despite hundreds of studies on the effects of expectations on evaluations, few commentaries have focused on summarising the relevance of these findings for physical activity pursuits. Moreover, a parsimonious framework on the nature of these relationships in physical activity is yet to be developed. Such a framework is important given the significance of physical activity evaluations in predicting future physical activity participation. Based on existing models on persuasion, it is premised that the self can be persuaded by one's own expectations about physical activity and that such persuasion can support or refute those expectations. Which of these effects are created, and the extent of one's psychological and physical involvement in the creation of physical activity evaluations, is likely to hinge on motivation and ability to confirm or disconfirm expectations. Evidence from related bodies of literature is presented to support the primary tenets of the model, which is termed the expectation‐to‐evaluation model, and recommendations for practitioners and future research are offered.
