RESUMEN
Elite athletes often make large personal sacrifices to pursue excellence, but there is insufficient support for them when they leave elite sport. Identity loss is central to athletes' transition trajectories and hence the management of identity change is a crucial area for support. The More Than Sport (MTS) program is a novel digital intervention that aims to provide this support-helping athletes manage identity change in the process of leaving elite sport. The present research aims to study elite athletes' experiences with the MTS program and their perceptions of its usefulness in managing the transition away from elite sport. We undertook a qualitative study with athletes (N = 25) from three countries (the United Kingdom, Australia and Belgium) using reflexive thematic analysis to explore their experiences of the program and their feedback on program content. We identified three key themes and eight subthemes. The first key theme was Value of the Program, and this was underpinned by four sub-themes that centred on Program importance and novelty, how Positive and confronting experiences afford insight, the Value of developing shared understanding, and Realising the value of social groups. The second key theme was Engagement with Program Elements and here participants commented on Program content and Delivery format. The final key theme was Time and Place for Identity Management Programs which included the sub-themes of Optimal timing and Additional program beneficiaries. Overall, the results highlight the value of MTS specifically, and identity management efforts more broadly, to help elite athletes adjust successfully to life beyond sport.
RESUMEN
Biceps femoris long head (BFLH) aponeurosis size was compared between legs with and without prior hamstring strain injury (HSI) using two approaches: within-group (injured vs. uninjured legs of previous unilateral HSI athletes) and between-group (previously injured legs of HSI athletes vs. legs of No Prior HSI athletes). MRI scans were performed on currently healthy, competitive male athletes with Prior HSI history (n=23;≥1 verified BFLH injury; including a sub-group with unilateral HSI history; most recent HSI 1.6±1.2 years ago) and pair-matched athletes with No Prior HSI history (n=23). Anonymized axial images were manually segmented to quantify BFLH aponeurosis and muscle size. Prior unilateral HSI athletes' BFLH aponeurosis maximum width, aponeurosis area, and aponeurosis:muscle area ratio were 14.0-19.6% smaller in previously injured vs. contralateral uninjured legs (paired t-test, 0.008≤P≤0.044). BFLH aponeurosis maximum width and area were also 9.4-16.5% smaller in previously injured legs (n=28) from Prior HSI athletes vs. legs (n=46) of No Prior HSI athletes (unpaired t-test, 0.001≤P≤0.044). BFLH aponeurosis size was smaller in legs with prior HSI vs. those without prior HSI. These findings suggest BFLH aponeurosis size, especially maximum width, could be a potential cause or consequence of HSI, with prospective evidence needed to support or refute these possibilities.
RESUMEN
Retirement is one of the most impactful career transitions athletes face. Researchers recognise the role that athletic identity plays in this, but analysis of identity content and change processes is limited. Addressing this gap, we conducted a qualitative study exploring the experience of identity change in 21 competitive and successful elite athletes who had retired from sport. All participated in a one-session psychoeducational program that explored the challenges of transitioning out of sport before being interviewed about their understanding of identity in sport, and their experiences negotiating identity loss and change in retirement. Using reflexive thematic analysis, we identified three themes: (i) the role of identity and self-categorizations in shaping sport performance, (ii) adjusting to identity loss (with subthemes indicating that this experience varied depending on the extent to which a person had multiple or exclusive identities), and (iii) attempts to remoor identity in the transition (with subthemes of searching for a new identity and actively repurposing identity). We interpret these themes through the lens of the Social Identity Model of Identity Change and show that this provides a framework for extending our understanding the complexities of identity change associated with retirement from elite sport.

The classic findings have been well described for light-chain amyloid involving the liver. In addition to light chain, however, many additional proteins are now known to be amyloidogenic and can involve the liver. A total of 58 surgical pathology specimens with amyloid deposits were analyzed for patterns of amyloid deposition, including amyloid from light chain lambda (N = 17), light chain kappa (N = 15), transthyretin (N = 15), serum amyloid A (N = 4), apolipoprotein A1 (N = 4), fibrinogen alpha (N = 2), LECT2 (N = 1). Amyloid deposits predominately targeted the liver vasculature, including the walls of the hepatic arteries, portal veins, and sinusoids. While there was overlap, light chain amyloid predominately involved the sinusoids, while transthyretin amyloid predominately targeted the hepatic arteries, especially the larger ones in the hilum and larger portal tracts. Serum amyloid A formed nodular deposits that started in the portal vasculature but then extended into the portal tract stroma, leading to large, bulbous, portal-based amyloid deposits. Apolipoprotein A amyloid also formed large portal-based nodules. Fibrinogen was mild and subtle on H&E and predominately affected portal veins. Amyloid deposits in hilar nerves were prominent with amyloid light chain, transthyretin, and apolipoprotein A1. In conclusion, the histology of hepatic amyloid is diverse and shows several distinct clusters of findings that can aide in recognition in surgical pathology specimens.

Perceived availability of social support can reduce symptoms of burnout in athletes. As such, it is important to understand the circumstances under which perceived social support is most effective. Social influences such as strength of social identification with a particular group or identity are believed to play an important role in the provision and effectiveness of social support. Across two studies, we investigate whether social identification in a sport can strengthen the protective association between perceived social support and burnout. In Study 1, athletes completed questionnaires assessing perceptions of social support availability, social identification, and burnout. In Study 2, participants completed the same measures at systematic time points across a six-month timespan. In both studies, participants' levels of social identification moderated the association between perceived social support and burnout, whereby there was a stronger negative relationship between social support and burnout when participants reported higher levels of social identification in their sport. These results indicate that social identity may play an integral role in improving the efficacy of social support on burnout.

Psychological stress can be both a help and a hindrance to wellbeing and performance in sport. The provision and receipt of social support is a key resource for managing adaptations to stress. However, extant literature in this area is largely limited to the recipient's perspective of social support. Furthermore, social support is not always effective, with evidence suggesting it can contribute to positive, negative, and indifferent adaptations to stress. As such, we do not know how social support influences adaptations to stress in sport. The social identity approach may explain how social support can lead to both positive and negative adaptations to stress. Our purpose in this study was to explore how social support and social identities influence adaptations to stress in a Rugby Academy Programme. Using qualitative methods within a naturalistic research paradigm, semi-structured interviews were conducted with Rugby Academy co-ordinators (n = 6) and players (n = 12), and four focus groups were conducted with teams of support staff (n = 18). Data were analyzed using reflexive thematic analysis, which generated seven sub-themes categorized into two higher-order analytical themes. Our results demonstrate that group-based perceptions of social support influence adaptations to stress. Specifically, whether social support influences positive, negative, or indifferent adaptations to stress depended on (1) social factors influencing the nature of social support, and (2) social factors influencing the provision and receipt of social support. These findings advance our understanding of how adaptations to stress are influenced by social support. Implications are offered for how organizations, teams, and practitioners can facilitate positive adaptations to stress in sport.
RESUMEN
High-impact exercise can improve femoral neck bone mass but findings in postmenopausal women have been inconsistent and there may be concern at the effects of high-impact exercise on joint health. We investigated the effects of a high-impact exercise intervention on bone mineral density (BMD), bone mineral content (BMC), and section modulus (Z) as well as imaging biomarkers of osteoarthritis (OA) in healthy postmenopausal women. Forty-two women aged 55 to 70 years who were at least 12 months postmenopausal were recruited. The 6-month intervention consisted of progressive, unilateral, high-impact exercise incorporating multidirectional hops on one randomly assigned exercise leg (EL) for comparison with the contralateral control leg (CL). Dual-energy X-ray absorptiometry (DXA) was used to measure BMD, BMC, and Z of the femoral neck. Magnetic resonance imaging (MRI) of the knee joint was used to analyze the biochemical composition of articular cartilage using T2 relaxometry and to analyze joint pathology associated with OA using semiquantitative analysis. Thirty-five participants (61.7 ± 4.3 years) completed the intervention with a mean adherence of 76.8% ± 22.5%. Femoral neck BMD, BMC, and Z all increased in the EL (+0.81%, +0.69%, and +3.18%, respectively) compared to decreases in the CL (-0.57%, -0.71%, and -0.75%: all interaction effects p < 0.05). There was a significant increase in mean T2 relaxation times (main effect of time p = 0.011) but this did not differ between the EL and CL, indicating no global effect. Semiquantitative analysis showed high prevalence of bone marrow lesions (BML) and cartilage defects, especially in the patellofemoral joint (PFJ), with no indication that the intervention caused pathology progression. In conclusion, a high-impact exercise intervention that requires little time, cost, or specialist equipment improved femoral neck BMD with no negative effects on knee OA imaging biomarkers. Unilateral high-impact exercise is a feasible intervention to reduce hip fracture risk in healthy postmenopausal women. © 2019 American Society for Bone and Mineral Research.

Social support is an adaptive resource associated with lower levels of burnout in sport. The effects of social support on burnout have typically been demonstrated through (1) a main effects model (direct negative associations between social support and burnout) and (2) a stress-buffering model (social support buffering the negative effects of stress on burnout). While both models provide insights into functional adaptations to burnout and stress in sport, evidence for significant main and stress-buffering effects are inconsistent. Reasons for this is include: (1) testing of a singular perspective of support in empirical research, and (2) a lack of specificity when analyzing social support and burnout (e.g., adoption of global-level analyses). To address this, the purpose of the study was to test differing perspectives of social support (perceived availability of support and received support) in regards to the main and stress-buffering effects of dimensions of social support (emotional, esteem, informational, and tangible) on dimensions of burnout (reduced sense of accomplishment, devaluation, emotional and physical exhaustion). Cross-sectional data were collected from 222 athletes. Moderated hierarchical regression analyses revealed that: (1) higher levels of stress were associated with higher levels of burnout (all dimensions); (2) higher levels of perceived availability of support were associated with lower levels of reduced sense of accomplishment and devaluation (with the exception of perceived availability of emotional support upon devaluation), and (3) perceived availability of emotional support buffered the negative effects of high stress upon devaluation. There were no significant main or interactive effects for any dimensions of received support. The significant interaction suggests that higher levels of perceived availability of emotional support may result in a functional adaptation to higher stress such that individuals may be protected from higher levels of devaluation of sport.
RESUMEN
OBJECTIVE: Quantifying spatial distribution of trabecular bone mechanical competence and microstructure is important for early diagnosis of skeletal disorders and potential risk of fracture. The objective of this study was to determine a spatial distribution of trabecular mechanical and morphological properties in human distal tibia and examine the contribution of regional variability of trabecular microarchitecture to mechanical competence. METHODS: A total of 340 representative volume elements at five anatomic regions of trabecular bone - anterior, posterior, lateral, medial and centre - from ten white European-origin postmenopausal women were studied. Region-specific trabecular parameters such as trabecular volume fraction, trabecular thickness, trabecular number, trabecular surface area, trabecular separation, plate-like structure fraction and finite element analysis of trabecular stiffness were determined based on in-vivo high resolution peripheral quantitative computed tomographic (HR-pQCT) images of distal tibiae from ten postmenopausal women. Mean values were compared using analysis of variance. The correlations between morphological parameters and stiffness were calculated. RESULTS: Significant regional variation in trabecular microarchitecture of the human distal tibia was observed (pâ¯<â¯0.05), with up to 106% differences between lowest (central and anterior) and highest (medial and posterior) regions. Higher proportion of plate-like trabecular morphology (63% and 53%) was found in medial and posterior regions in the distal tibia. Stiffness estimated from finite element models also differed significantly (pâ¯<â¯0.05), with stiffness being 4.5 times higher in the highest (medial) than lowest (central) regions. The bone volume fraction was the strongest correlate of stiffness in all regions. CONCLUSION: A novel finding of this study is the fact that significant regional variation of stiffness derived from two-phased FEA model with individual trabecula representation correlated highly to regional morphology obtained from in-vivo HR-pQCT images at the distal tibia. The correlations between regional morphological parameters and mechanical competence of trabecular bone were consistent at all regions studied, with regional BV/TV showing the highest correlation. The method developed for regional analysis of trabecular mechanical competence may offer a better insight into the relationship between mechanical behaviour and microstructure of bone. The findings provide evidence needed to further justify a larger-cohort feasibility study for early detection of bone degenerative diseases: examining regional variations in mechanical competence and trabecular specifications may allow better understanding of fracture risks in addition to others contributing factors.

RESUMEN
OBJECTIVE: To assess the results of the use of the free radial forearm flap in terms of objective morbidity and subjective patient response. STUDY DESIGN: The donor sites were examined from 37 patients who underwent reconstruction with a free fasciocutaneous radial forearm flap in the head and neck after ablative tumor surgery. METHODS: Patients were asked to fill in a written questionnaire. The following additional tests were performed: resting skin temperature of digits I and V, temperature after submersion in iced water, grip and pinch tests, and goniometry. RESULTS: Resting skin temperature was slightly decreased for donor hands 0.69 degrees C (P < .001) and 0.31 degrees C (P = .048) for digits I and V, respectively, but recovery after submersion in iced water showed no differences. The strength tests and goniometry revealed no statistically significant findings between donor and control sides. On the questionnaire, 9 patients (24%) reported slightly impaired function, 14 (38%) could not wear their watch or bracelet, 17 (46%) reported numbness, 5 (14%) reported soreness, 5 (14%) reported itching, 6 (16%) reported cold intolerance, 5 (14%) reported bad cosmetic appearance, and 9 (24%) expressed the opinion that they were insufficiently counseled. CONCLUSION: There is a negligible objective morbidity of a free radial forearm flap harvest procedure, but a number of patients have subjective complaints when asked. Elaborate presurgical counseling can probably reduce these complaints.
