Exercise imagery can be beneficial for insufficiently active people as a means to promote physical activity (PA) engagement and positive psychological states. The present study explored imagery use in physically active and insufficiently active older adults. The revised applied model of deliberate imagery use (RAMDIU) was used as a framework to explain When, Where, Why, What, and How older adults image and explored whether the Who component of the model (older adults/PA status) interacts with these different components; 37 (M age = 64, SD = 5.2; 17 females) participants representing a range of PA levels took part in one of seven focus groups. Thematic analysis provided support for RAMDIU, with motivation, memory, and planning identified as the most common imagery functions, and scenery and reward images as the most commonly reported imagery content. Although some similarities exist, older adults tend to use imagery for unique functions compared with younger counterparts (e.g., to improve memory). Understanding the use of imagery in older adults will help to tailor PA interventions for promoting healthy aging in this population.

BACKGROUND Adolescent girls are more likely to be inactive than boys. A range of factors including multiple psychosocial aspects are thought to influence their engagement in physical activity (PA). This study aimed to explore adolescent girls’ perceptions and experiences of school-based PA to inform a subsequent intervention, the Girls Peer Activity (G-PACT) project. METHODS The Youth Activity Profile was used to assess adolescent girls’ current PA levels. Open-ended questions were used to investigate girls’ perceptions and experiences of school-based PA. Focus groups stratified by PA level were then conducted to explore their perceptions and experiences in depth. The focus group data were analysed using inductive thematic analysis. RESULTS The master themes emanating from the focus groups were non-competitive activities and after-school sport culture for lower active girls. Higher active girls’ master themes were PA perceptions and PE. Regardless of activity level, participants reported greater enjoyment from PA when participating with friends and having choice over activities provided within the school setting. CONCLUSIONS The findings highlight the importance of choice, peer groupings, non-competitive opportunities and PA competence to adolescent girls’ school-based PA behaviours. The school environment can support and restrict girls’ engagement in PA. The findings will be applied to the design, content and implementation of the G-PACT project.

Regular physical activity (PA) is associated with numerous physical and psychological health benefits. Adolescents, specifically girls, are at risk of physical inactivity. To date, there is limited research on PA interventions involving peers, which could encourage more adolescent girls to engage in PA. The investigation aimed to evaluate the feasibility of a novel school three-tier peer-led mentoring model designed to improve PA levels and reduce sedentary time (ST) of adolescent girls. Two-hundred and forty-nine Year 9 adolescent girls (13–15 years old) from three UK secondary schools were invited to participate in a peer-led mentoring intervention (Girls Peer Activity (G-PACT) project). The peer-led mentoring model was delivered in all three schools. Two of the schools received an additional after-school PA component. PA and ST were assessed through wrist-worn accelerometry. Girls who received an exercise class after-school component significantly increased their whole day moderate-to-vigorous PA (MVPA) (3.2 min, p = 0.009, d = 0.33). Girls who received no after-school component significantly decreased their MVPA (3.5 min, p = 0.016, d = 0.36) and increased their ST (17.2 min, p = 0.006, d = 0.43). The G-PACT intervention demonstrated feasibility of recruitment and data collection procedures for adolescent girls. The peer-led mentoring model shows promise for impacting girls’ MVPA levels when combined with an after-school club PA opportunity.

Enjoyment of physical activity (PA) is positively correlatedwith PAengagement. The inclusion of peers has been found to increase the likelihood of PAenjoyment in youth. Peer-led strategies, incorporating peer networks in the intervention delivery, is relatively underused and consequently understudied in school-based PA interventions. The purpose of this investigation was to evaluate the feasibility and acceptability of the novel Girls Peer Activity (G-PACT) peer-ledmentoring intervention. Two-hundred and forty-nine Year 9 adolescent girls (13–14 years old) fromthreemixed-sex secondary schools located inWest Lancashire, North-West England were invited to participate in the G-PACT project. The study employed a novel approach by using a three-tier model, including (Tier 1) Mentors (undergraduate students), (Tier 2) Leaders (Year 9 girls selected by teachers), and (Tier 3) Peers (whole Year 9 cohort). Mentors delivered a series of educational and leadership training to the Leaders in each respective school who then disseminated this information to their Peers and encouraged themto engage inmore physical activities. Eight focus groups were conducted with Leaders (n = 40), 28 focus groups with Peers (n = 185), two focus groups with Mentors (n = 6), and three interviews with teachers (n = 4). Thematic analysis was used to analyze the pooled data and identify the key themes. The study found that the G-PACT intervention was feasible and acceptable for adolescent PA Leaders and theirMentors. The relationship between Leaders and their Peers required refinement to improve the communication processes to increase Peer engagement in the G-PACT project.

Limited research has investigated exercise imagery use in middle-aged and older adults and its relationship with affective and behavioural correlates. The study examined the association between self-regulatory imagery and physical activity (PA) through key social cognitive variables. Middle-aged and older adults (N = 299; Mage = 59.73 years, SD = 7.73, range = 50 to 80) completed self-report measures assessing self-regulatory imagery use, self-efficacy, outcome expectations, perceived barriers, self-regulatory behaviour, enjoyment, and PA levels. Path analysis supported a model (χ2 (14) = 21.76, p = .08, CFI = .99, TLI = .97, SRMR = .03, RMSEA = .04) whereby self-regulatory imagery positively predicted self-efficacy, outcome expectations, and self-regulatory behaviours. Furthermore, self-regulatory imagery indirectly predicted barriers, outcome expectations, self-regulation, enjoyment, and PA. This research highlights self-regulatory imagery as an effective strategy in modifying exercise-related cognitions and behaviours. Incorporating social cognitive constructs into the design of imagery interventions may increase PA engagement.

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.

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.

Introduction. Research suggests that sport involvement enhances body image [1]. Research also indicates that athletes involved in certain sports, such as gymnastics and distance running, are at risk for body image disturbances [2]. Aim of the Study. The purpose of this research was to explore this apparent paradox, that physical activity enhances body image but athletes in certain sports may be at risk for body image concerns. Material and Methods. The sport and societal attractiveness body image ideals of female long distance runners (n = 21) and throwers (n = 18) were assessed via questionnaires, line drawings, and digital body image software. Results. Consistent with social comparison theory, long distance runners were more satisfied with their bodies than were throwers when considering societal attractiveness ideals. Throwers, however, were more satisfied with their bodies than were distance runners when considering sport ideals. When considering body image without regard to the different body ideals, distance runners reported a more favorable body image overall than did throwers. Conclusions. These results suggest that complex factors affect the body image of women athletes. With regard to body image measurement, digital body image software may be more sensitive than line drawings in detecting predicted relationships.
