Imagery use in older adults

Underpinned by Bandura’s social-cognitive theory (SCT), this thesis examined the perceptions of physical activity (PA) in healthy and unhealthy older adults, and examined imagery as a potential strategy to promote PA. Focus groups with healthy older adults (Chapter 2) and those diagnosed with chronic obstructive pulmonary disease (COPD) (Chapter 3) examined how PA is incorporated into daily living, and the unique barriers and enablers of PA in older adults. The subsequent chapters focus on the role of imagery as a strategy to increase PA. Using the revised applied model of deliberate imagery use as a framework, Chapter 4 explored where, when, what, and why older adults image PA. Based on Chapter 2 and 3’s finding that older adults use a range of imagery types and functions, and the importance of self-regulation, Chapter 5 investigated how self-regulatory imagery (i.e., images of goals and planning) related with social-cognitive variables, enjoyment, and PA. Overall, the thesis recognises the importance of SCT in explaining the unique challenges older adults face in relation to PA while accounting for contextual factors including PA level, disease severity, and employment status. The thesis also demonstrates imagery as a potential strategy for promoting PA in older adults

Investigating the Psychosocial Determinants of Physical Activity in Older Adults: A Qualitative Approach

Objective: Despite the benefits of physical activity (PA), only one-third of older adults meet the recommended levels. The present study focused on psychosocial determinants of PA following retirement. Social cognitive theory (SCT) was used to better understand pre- and post-retirement adults’ thoughts about PA, the reasons why some individuals are more active than others, and how PA is incorporated into daily life after retirement. Design: Seven focus groups of older adults (N = 37, M = 64, SD = 5.20; males = 20) representing a range of PA levels and retirement length participated in one of seven focus groups. Results: Aligned with SCT, self-efficacy beliefs along with perceptions about barriers and benefits of PA were among the major determinants of PA. Findings highlighted the importance of social support, positive outcome expectations and self-regulatory strategies as motivators. The lack of structure in retirement was a hindrance to incorporating PA into daily routine but, when incorporated, PA provided a sense of purpose in the lives of retired individuals. Conclusion: It is important to understand the meaning of retirement as a life transition and how it affects beliefs about PA to inform SCT-based health promotion interventions targeting individuals in retirement age

Barriers and enablers of physical activity engagement for patients with COPD in primary care

Maria-Christina Kosteli,1 Nicola R Heneghan,1 Carolyn Roskell,1 Sarah E Williams,1 Peymane Adab,2 Andrew P Dickens,2 Alexandra Enocson,2 David A Fitzmaurice,2 Kate Jolly,2 Rachel Jordan,2 Sheila Greenfield,2 Jennifer Cumming1 1School of Sport, Exercise and Rehabilitation Sciences, 2Institute of Applied Health Research, University of Birmingham, Edgbaston, Birmingham, UK Background: Given that physical activity (PA) has a positive impact on COPD symptoms and prognosis, this study examined the factors that both encourage and limit participation in PA for individuals with COPD in a primary care setting from the perspective of social cognitive theory.Methods: A purposive sample of 26 individuals with a range of COPD severity (age range: 50–89 years; males =15) were recruited from primary care to participate in one of four focus groups. Thematic analysis was undertaken to identify key concepts related to their self-efficacy beliefs.Results: Several barriers and enablers closely related to self-efficacy beliefs and symptom severity were identified. The main barriers were health related (fatigue, mobility problems, breathing issues caused by the weather), psychological (embarrassment, fear, frustration/disappointment), attitudinal (feeling in control of their condition, PA perception, older age perception), and motivational. The main enabling factors were related to motivation (autonomous or controlled), attitudes, self-regulation, and performance accomplishments.Clinical implications: When designing interventions for individuals with COPD, it is important to understand the patient-specific social cognitive influences on PA participation. This information can then inform individually tailored management planning. Keywords: COPD, social cognitive theory, self-efficacy, barriers, enablers, primary car

The acceptability and feasibility of a novel peer-led schoolbased physical activity intervention for adolescent girls: The girls' peer activity (G-PACT) project

Meeting abstract presented at 7th International Society for Physical Activity and Health Congress, London, England, 15-17 October, 2018.Introduction: This study assessed the feasibility and acceptability of a novel peer-led physical activity (PA) intervention for adolescent girls aged 13-14 years. Methods: The intervention employed a three-tier peer-led model under- pinned by Social Cognitive Theory (SCT) and Self-Determination Theory (SDT). The 8-week intervention was delivered in three schools and involved 233 participants. Each school recruited 12-16 girls to become PA-leaders, who received leadership training delivered by undergraduate PA students, who subsequently acted as their intervention mentors and role models. The PA-leaders were encouraged to support their school peers to engage in more PA. Two of the schools provided organised after- school PA opportunities which the PA-leaders actively promoted. The acceptability, practicality, engagement, and perceived success of the intervention was investigated using focus groups and interviews. Qualitative analysis adopted deductive and inductive methods, using SCT and SDT as thematic frameworks, and then exploring additional emergent themes. Results: The intervention was perceived as feasible and acceptable between mentors (n = 6) and leaders (n = 47). However, the relationship between leaders and their peers (n = 196) suggested uncertainty in delivery and engagement Disparity was reported from the peers in how much and what information was conveyed to them by their PA-leaders. Conclusions: This intervention was reported to be feasible and acceptable among mentors and PA-leaders. Teachers were supportive of the intervention and the intervention demonstrates innovation incorporating undergraduate students as mentors and role models to adolescent girls. Further research is needed to clarify the roles and responsibilities for the PA-leaders.External funding details: This research was funded by Edge Hill University

Nanoformulated Copper/Zinc Superoxide Dismutase Reduces Adipose Inflammation in Obesity

Objective: An intimate association exists between oxidative stress and inflammation. Because adipose tissue (AT) inflammation is intricately linked to metabolic disorders, it was hypothesized that reducing oxidative stress would be effective in ameliorating AT inflammation in obesity. Methods: Wild-type mice were fed a high-fat diet (HF) for 8 weeks followed by a 2-week treatment with nanoformulated copper/zinc superoxide dismutase (NanoSOD). The mice were divided into: 1) chow diet, 2) HF, and 3) HF + NanoSOD. Results: The HF + NanoSOD-treated mice showed a significant decrease in plasma and liver triglycerides when compared with HF-fed mice. Interestingly, NanoSOD reduced the expression of macrophage and inflammatory markers in visceral AT (VAT) and stromal cells derived from VAT. Moreover, the activation of proinflammatory signaling pathways, in particular, the extracellular signal-regulated kinases, was blunted in VAT on NanoSOD treatment. However, markers of oxidative stress were not altered significantly in the HF + NanoSOD group in the experimental conditions. Pretreatment of either macrophages or adipocytes significantly reduced the inflammatory response invoked in an in vitro coculture system, further supporting the role of NanoSOD in inhibiting obesity-linked inflammation. Conclusions: This data suggest that NanoSOD is effective not only in reducing AT macrophage accumulation and AT inflammation but also in promoting triglyceride metabolism in obesity

Physical activity for cystic fibrosis: perceptions of people with cystic fibrosis, parents and healthcare professionals

This is the final version. Available on open access from the European Respiratory Society via the DOI in this recordData availability: All available data can be obtained by contacting the corresponding authorBackground The benefits of physical activity (PA) for people with cystic fibrosis (pwCF) are widely accepted, yet how PA is promoted and utilised by pwCF is unclear. Method An online questionnaire to explore attitudes, practices and promotion of PA in cystic fibrosis was completed by healthcare providers (HCP), pwCF and parents/caregivers. Results 351 respondents (105 HCP, 120 pwCF, and 126 parents/caregivers) from 12 countries completed the survey. Importance of PA was rated highly by the majority of respondents. Physical (e.g. health), psychological (e.g. enjoyment) and social (e.g. social interaction) factors were motives for PA for 82%, 49% and 37% of pwCF, respectively, irrespective of country. Common barriers to PA included time (49% and 36%) and tiredness (61% and 7%) for pwCF and parents/carers, respectively. pwCF also reported psychosocial barriers (e.g. stigma, demoralisation), while parents/caregivers reported structural barriers (e.g. cost). Clinical teams varied substantially in terms of the emphasis placed on PA, facilities available, staff and training, and advice given to pwCF. Conclusion Despite the majority of participants rating the importance of PA highly, substantial variability was evident regarding the facilities and clinical support available to them, as well as why and how people were active. There remains a need to identify what constitutes “best practice” for PA promotion within clinics.Cystic Fibrosis Trus

How the Bright and Dark Side of Self-Determination Theory Influence Participants' Life Skills Development in Youth Sport

Objectives: This study investigated whether basic needs satisfaction versus frustration mediated the relationships between autonomy-supportive versus controlling coaching and participants’ life skills development in youth sport. Design: This descriptive study used a cross-sectional research design. To ensure a diverse sample, participants were recruited from a wide range of sports. Methods: British and Irish youth sport participants (N = 309) completed measures of autonomy-supportive and controlling coaching, basic need satisfaction versus frustration (autonomy, competence, and relatedness), and life skills development in sport (teamwork, goal setting, social skills, problem solving, emotional skills, leadership, time management, and communication skills). Results: Correlational analyses showed that coach autonomy support was positively related to participants’ basic need satisfaction and life skills development. Controlling coaching was only positively associated with participants’ basic need frustration. Mediational analyses revealed that satisfaction of the three needs combined mediated the relationships between coach autonomy support and participants’ development of all eight life skills. Relatedness satisfaction mediated the relationships between coach autonomy support and participants’ development of all life skills except for goal setting. Autonomy satisfaction only mediated the relationships between coach autonomy support and time management; whereas, competence satisfaction mediated the relationships between coach autonomy support and participants’ goal setting and emotional skills. Conclusions: Findings indicated that basic need satisfaction is a mechanism that helps explain the relationships between coach autonomy support and sport participants’ life skills development. As such, coaches should create an autonomy-supportive climate that satisfies participants’ three basic needs and may help to develop their life skills

A self-determination theory based investigation of life skills development in youth sport

This study investigated if basic need satisfaction and frustration mediated the associations between autonomy-supportive and controlling coaching behaviours and participants’ development of eight different life skills in youth sport. British sports participants (N = 309, Mage = 14.71) completed measures assessing the study variables. Correlational analyses showed that autonomy-supportive coaching behaviours were positively associated with the satisfaction of participants’ three basic needs (autonomy, competence, and relatedness) and their development of all eight life skills, whereas controlling coaching behaviours were only positively related to the frustration of participants’ three basic needs. Mediational analyses revealed that satisfaction of all three basic needs combined (total need satisfaction) mediated the associations between autonomy-supportive coaching behaviours and participants’ development of the eight life skills. Relatedness satisfaction mediated the associations between autonomy-supportive coaching behaviours and participants’ development of all eight life skills except for goal setting; autonomy satisfaction mediated the associations between autonomy-supportive coaching behaviours and participants’ time management skills; and competence satisfaction mediated the associations between autonomy-supportive coaching behaviours and participants’ goal setting and emotional skills. Based on such findings, coaches should look to display autonomy-supportive behaviours that help to satisfy participants’ three basic psychological needs and promote their life skills development in sport
