RESUMEN
People with advanced cancer and cachexia experience significant body weight loss, adversely impacting physical function and quality of life (QOL). Effective, evidence-based treatments for cancer cachexia are lacking, leaving patients with unmet needs. Exercise holds promise to improve patient QOL. However, information on patients' experiences of exercise, including their ability to cope with structured exercise, is limited. PURPOSE: To explore patient experiences completing a structured, supervised exercise program for people with cachexia due to advanced cancer. METHODS: Semi-structured interviews were conducted with participants enrolled in a phase II feasibility, randomized controlled trial to explore their experiences of an 8-week virtually supervised exercise program delivered via videoconference technology. Interviews were analysed using reflexive thematic analysis. RESULTS: Seventeen participants completed interviews (female n = 9, 53%). Main interview themes included the following: (1) Deciding to exercise involves balancing concerns and expectations, (2) the exercise program is a positive experience, and (3) moving forward after the exercise program. While some participants initially held doubts about their physical capabilities and exercise safety, most wanted to exercise to enhance their wellbeing. Participants described the exercise program as a positive experience, offering diverse benefits. Some would have preferred in-person exercise, but all agreed the virtual format increased convenience. Participants emphasized the need to recommend the program to others in similar circumstances. They underscored the necessity and desire for ongoing support to sustain their new exercise habits. CONCLUSION: Based on patient experiences, virtually supervised exercise programming appears to be feasible and meaningful to people with advanced cancer and cachexia.

BACKGROUND: Implementation science seeks to systematically identify determinants, strategies, and outcomes within a causal pathway to help explain successful implementation. This process is applied to evidence-based interventions (EBIs) to improve their adoption, implementation, and sustainment. However, this method has not been applied to exercise oncology services, meaning we lack knowledge about implementing exercise EBIs in routine practice. This study aimed to develop causal pathways from the determinants, strategies (including mechanism of change), and implementation outcomes to explain exercise EBIs implementation in routine cancer care. METHODS: A multiple-case study was conducted across three healthcare sites in Australia. Sites selected had implemented exercise within routine care for people diagnosed with cancer and sustained the delivery of services for at least 12 months. Four data sources informed the study: semi-structured interviews with staff, document reviews, observations, and the Program Sustainability Assessment Tool (survey). Framework analysis was applied to understand the findings. The Implementation Research Logic Model was used to identify commonalities in implementation across sites and develop causal pathways. RESULTS: Two hundred and eighteen data points informed our findings. Across sites, 18 determinants and 22 implementation strategies were consistent. Sixteen determinants and 24 implementation strategies differed across sites and results of implementation outcomes varied. We identified 11 common pathways that when combined, help explain implementation processes. The mechanisms of implementation strategies operating within the pathways included (1) knowledge, (2) skills, (3) secure resources, (4) optimism, and (5) simplified decision-making processes associated with exercise; (6) relationships (social and professional) and support for the workforce; (7) reinforcing positive outcomes; (8) capability to action plan through evaluations and (9) interactive learning; (10) aligned goals between the organisation and the EBI; and (11) consumer-responsiveness. CONCLUSION: This study developed causal pathways that explain the how and why of successful implementation of exercise EBIs in cancer care. These findings can support future planning and optimisation activities by creating more opportunities for people with cancer to access evidence-based exercise oncology services. IMPLICATIONS FOR CANCER SURVIVORS: Understanding how to implement exercise within routine cancer care successfully is important so cancer survivors can experience the benefits of exercise.

Background: While therapeutically effective, chemoradiotherapy treatment for high-grade glioma (glioblastoma) is often accompanied by side effects. Exercise has been demonstrated to alleviate the adverse effects of such treatments in other cancers. We aimed to evaluate the feasibility and preliminary efficacy of supervised exercise incorporating autoregulation. Methods: Thirty glioblastoma patients were recruited, five declined exercise and 25 were provided with a multimodal exercise intervention for the duration of their chemoradiotherapy treatment. Patient recruitment, retention, adherence to training sessions and safety were evaluated throughout the study. Physical function, body composition, fatigue, sleep quality, and quality of life were evaluated before and after the exercise intervention. Results: Eight of the 25 participants commencing exercise withdrew prior to completion of the study (32%). Seventeen patients (68%) demonstrated low to high adherence (33%-100%) and exercise dosage compliance (24%-83%). There were no reported adverse events. Significant improvements were observed for all trained exercises and lower limb muscle strength and function with no significant changes observed for any other physical function, body composition, fatigue, sleep, or quality of life outcomes. Conclusions: Only half of glioblastoma patients recruited were willing or able to commence, complete or meet minimum dose compliance for the exercise intervention during chemoradiotherapy indicating the intervention evaluated may not be feasible for part of this patient cohort. For those who were able to complete the exercise program, supervised, autoregulated, multimodal exercise was safe and significantly improved strength and function and may have prevented deterioration in body composition and quality of life.
RESUMEN
BACKGROUND: Regular exercise has been shown to have beneficial health effects in cancer survivors, including improving quality of life and other important health outcomes. However, providing people with cancer with easily accessible, high-quality exercise support and programs is a challenge. Therefore, there is a need to develop easily accessible exercise programs that draw upon the current evidence. Supervised, distance-based exercise programs have the benefit of reaching out to many people whilst providing the support of an exercise professional. The aim of the EX-MED Cancer Sweden trial is to examine the effectiveness of a supervised, distance-based exercise program, in people previously treated for breast, prostate, or colorectal cancer, on health-related quality of life (HRQoL), as well as other physiological and patient-reported health outcomes. METHODS: The EX-MED Cancer Sweden trial is a prospective randomised controlled trial including 200 people that have completed curative treatment for breast, prostate, or colorectal cancer. Participants are randomly allocated to an exercise group or a routine care control group. The exercise group will participate in a supervised, distanced-based exercise program delivered by a personal trainer who has undertaken specialised exercise oncology education modules. The intervention consists of a combination of resistance and aerobic exercises with participants completing two 60-min sessions per week for 12 weeks. The primary outcome is HRQoL (EORTC QLQ-C30) assessed at baseline, 3- (end of intervention and primary endpoint) and 6-months post-baseline. Secondary outcomes are physiological (cardiorespiratory fitness, muscle strength, physical function, body composition) and patient-reported outcomes (cancer-related symptoms, fatigue, self-reported physical activity), and self-efficacy of exercise. Furthermore, the trial will explore and describe the experiences of participation in the exercise intervention. DISCUSSION: The EX-MED Cancer Sweden trial will provide evidence regarding the effectiveness of a supervised, distance-based exercise program for survivors of breast, prostate, and colorectal cancer. If successful, it will contribute to the implementation of flexible and effective exercise programs as part of the standard of care for people following cancer treatment, which is likely to contribute to a reduction in the burden of cancer on the individual, health care system and society. TRIAL REGISTRATION: www. CLINICALTRIALS: gov NCT05064670. Registered on October 1, 2021.

AIMS: Physical activity interventions are recommended for community-based youth mental health services to prevent physical health disparities. Implementation is challenging, and studies focusing on the methods to achieve change are needed. This study aims to identify the context, implementation strategies, and implementation outcomes that illustrate how physical activity interventions were implemented within an early intervention service in Australia. METHODS: A theoretically informed case study was undertaken. Data from a community-based youth mental health service that delivers an early psychosis programme were collected between July and November 2020. Three data sources were accessed (1) interviews with service managers, mental health clinicians and exercise physiologists; (2) document review of organizational policies and procedures; and (3) survey using the Program Sustainability Assessment Tool. The implementation outcomes investigated were acceptability, fidelity, penetration, and sustainability. Framework analysis was used, and a logic model developed guided by an established template, to interpret findings. RESULTS: Forty-three contextual factors and 43 implementation strategies were identified. The data suggests that creating a new clinical team and auditing and feedback are critical for implementation. High levels of acceptability and sustainability were described, while fidelity of implementation was difficult to establish, and penetration was low. CONCLUSIONS: The relationship between constructs suggests several mechanisms underpinned implementation. These include changing professional beliefs, establishing new organizational norms, augmenting existing work processes, and aligning physical activity with priorities of the mental healthcare system and existing work tasks. This case study provides direction for future health service planning of physical activity interventions in community-based youth mental health service.

BACKGROUND: Radiotherapy (RT) can lead to cancer-related fatigue (CRF) and decreased health-related quality of life (HRQoL) in breast cancer patients. The purpose of this trial was to examine the feasibility and efficacy of a home-based resistance and aerobic exercise intervention for reducing CRF and improving HRQoL in breast cancer patients during RT. METHODS: Women with breast cancer (N = 106) commencing RT were randomized to 12 weeks of home-based resistance and aerobic exercise (EX) or usual care/control (CON). The primary endpoint was CRF, with secondary endpoints of HRQoL, sleep duration and quality, and physical activity. Measurements were undertaken prior to RT, at completion of RT (~ 6 weeks), at completion of the intervention (12 weeks), and 6 and 12 months after RT completion, while CRF was also measured weekly during RT. RESULTS: Eighty-nine women completed the study (EX = 43, CON = 46). Over the 12-week intervention, EX completed 1-2 resistance training sessions and accumulated 30-40 min of aerobic exercise weekly. For CRF, EX had a quicker recovery both during and post-RT compared to CON (p < 0.05). Moreover, there was a significant difference in HRQoL between groups at RT completion, with HRQoL unchanged in CON and higher in EX (p < 0.05). There was no change in sleep duration or quality for either group and there were no exercise-related adverse effects. CONCLUSIONS: Home-based resistance and aerobic exercise during RT is safe, feasible, and effective in accelerating CRF recovery and improving HRQoL. Improvements in CRF and HRQoL for these patients can be achieved with smaller exercise dosages than stated in the generic recommendations for breast cancer.

BACKGROUND: Implementation science frameworks explore, interpret, and evaluate different components of the implementation process. By using a program logic approach, implementation frameworks with different purposes can be combined to detail complex interactions. The Implementation Research Logic Model (IRLM) facilitates the development of causal pathways and mechanisms that enable implementation. Critical elements of the IRLM vary across different study designs, and its applicability to synthesizing findings across settings is also under-explored. The dual purpose of this study is to develop an IRLM from an implementation research study that used case study methodology and to demonstrate the utility of the IRLM to synthesize findings across case sites. METHOD: The method used in the exemplar project and the alignment of the IRLM to case study methodology are described. Cases were purposely selected using replication logic and represent organizations that have embedded exercise in routine care for people with cancer or mental illness. Four data sources were selected: semi-structured interviews with purposely selected staff, organizational document review, observations, and a survey using the Program Sustainability Assessment Tool (PSAT). Framework analysis was used, and an IRLM was produced at each case site. Similar elements within the individual IRLM were identified, extracted, and re-produced to synthesize findings across sites and represent the generalized, cross-case findings. RESULTS: The IRLM was embedded within multiple stages of the study, including data collection, analysis, and reporting transparency. Between 33-44 determinants and 36-44 implementation strategies were identified at sites that informed individual IRLMs. An example of generalized findings describing "intervention adaptability" demonstrated similarities in determinant detail and mechanisms of implementation strategies across sites. However, different strategies were applied to address similar determinants. Dependent and bi-directional relationships operated along the causal pathway that influenced implementation outcomes. CONCLUSIONS: Case study methods help address implementation research priorities, including developing causal pathways and mechanisms. Embedding the IRLM within the case study approach provided structure and added to the transparency and replicability of the study. Identifying the similar elements across sites helped synthesize findings and give a general explanation of the implementation process. Detailing the methods provides an example for replication that can build generalizable knowledge in implementation research.
RESUMEN
Physical activity (PA) has shown to mitigate many of the common side effects of cancer treatments. The promotion of PA by health care professionals (HCPs) can facilitate the adoption of PA by patients with cancer. Drawing on an empirical ethics of care approach, this article explores how the delivery of PA recommendations is done within clinical cancer care. Based on 175 observations of consultations between doctors, nurses and patients and interviews with 27 doctors and nurses, we show how delivering PA recommendations was related to four care practices: "adjusting information to match the patient's needs and situation," "managing current and anticipated treatment-induced side effects," "using visual aids and quantifiable data," and "maintaining a good relationship between the patient and the HCP." Drawing on these findings, we discuss strategies to strengthen the delivery of PA recommendations in clinical cancer care.

Cachexia is a prevalent muscle wasting syndrome among people with advanced cancer that profoundly impacts patient quality of life (QoL) and physical function. Exercise can improve QoL, physical function, and overall health in people with cancer and may be an important addition to treatment approaches for cancer cachexia. Greater understanding of patients' perception of exercise can help elucidate the feasibility of implementing exercise interventions for cancer cachexia and facilitate the design of patient-centered interventions. We aimed to describe the perception of exercise in patients with advanced cancer and cachexia, and capture exercise motivators, barriers, and preferences, to inform the feasibility of exercise interventions. Individual interviews (n = 20) with patients with locally advanced or metastatic cancer with cachexia were conducted and analyzed using reflexive thematic analysis. Main themes from interviews were: 1) Life is disrupted by cancer and cachexia; 2) Exercise offers hope; 3) Exercise barriers are multifaceted; and 4) Exercise access and support are important. Participants reported that their cancer and cachexia had intensely altered their lives, including ability to exercise. Exercise was perceived as important and participants described a hope for exercise to improve their health and wellbeing. Yet, several complex exercise barriers, such as burdensome cancer symptoms and the overwhelming impact of the COVID-19 pandemic, hindered exercise participation and prevented participants from fully realizing the perceived benefits of exercise. Factors believed to improve exercise engagement and overcome exercise barriers included increased exercise support (e.g., professional supervision) and accessibility (e.g., convenient locations). Patient-reported exercise barriers and preferences can inform the design of exercise interventions, particularly within future research studies aiming to establish exercise feasibility and efficacy in people with advanced cancer and cachexia.

PURPOSE: Exercise has been underutilized in people with advanced or incurable cancer despite the potential to improve physical function and reduce psychosocial morbidity, especially for people with bone metastases because of concerns over skeletal complications. The International Bone Metastases Exercise Working Group (IBMEWG) was formed to develop best practice recommendations for exercise programming for people with bone metastases on the basis of published research, clinical experience, and expert opinion. METHODS: The IBMEWG undertook sequential steps to inform the recommendations: (1) modified Delphi survey, (2) systematic review, (3) cross-sectional survey to physicians and nurse practitioners, (4) in-person meeting of IBMEWG to review evidence from steps 1-3 to develop draft recommendations, and (5) stakeholder engagement. RESULTS: Recommendations emerged from the contributing evidence and IBMEWG discussion for pre-exercise screening, exercise testing, exercise prescription, and monitoring of exercise response. Identification of individuals who are potentially at higher risk of exercise-related skeletal complication is a complex interplay of these factors: (1) lesion-related, (2) cancer and cancer treatment-related, and (3) the person-related. Exercise assessment and prescription requires consideration of the location and presentation of bone lesion(s) and should be delivered by qualified exercise professionals with oncology education and exercise prescription experience. Emphasis on postural alignment, controlled movement, and proper technique is essential. CONCLUSION: Ultimately, the perceived risk of skeletal complications should be weighed against potential health benefits on the basis of consultation between the person, health care team, and exercise professionals. These recommendations provide an initial framework to improve the integration of exercise programming into clinical care for people with bone metastases.

INTRODUCTION: Exercise is vital to health and well-being after a cancer diagnosis yet is poorly integrated in cancer care. Knowledge mobilization (KM) is essential to enhance exercise opportunities. We aimed to (1) develop and refine a list of highly important exercise oncology research and KM themes and (2) establish the relative importance of the themes for supporting the implementation of exercise as a standard of care for people living with and beyond cancer. METHODS: Informed by the Co-Produced Pathway to Impact KM framework, a modified Delphi study approach was used to develop, rate, and rank exercise oncology research and KM themes through an international stakeholder workshop and a three-round iterative online survey. Open-ended stakeholder feedback from cancer survivors, healthcare practitioners (HCPs), qualified exercise professionals (QEPs), policy makers, and researchers was used to update themes between survey rounds. Themes were ranked from highest to lowest importance and agreement was examined across all stakeholders and within stakeholder groups. RESULTS: A total of 269 exercise oncology stakeholders from 13 countries participated in the study. Twelve final exercise oncology research and KM themes were produced. The final top ranked research themes were related to: (1) QEP integration into primary cancer care teams, (2) Exercise oncology education for HCPs, and (3) Accessibility of cancer exercise programs & support services. There was statistically significant agreement between stakeholders (p<0.001) and within stakeholder groups (p's≤0.02) on the general rankings of themes (i.e., some themes generally ranked higher and lower compared to others). Low Kendall's W statistics indicated variability related to the specific ranked order of the themes between stakeholders and within stakeholder groups. Moreover, there were key differences in the rankings for specific themes between policy makers and other stakeholder groups that highlight potentially important discordance in the research and KM priorities for policy makers that warrants further study. CONCLUSION: These findings can be used to guide initiatives and align stakeholders on priorities to support exercise implementation as a standard of cancer care. Additional research is needed to better understand the differences in the proposed research and KM priorities across stakeholders.
RESUMEN
BACKGROUND: Exercise has the potential to improve physical function and quality of life in individuals with bone metastases but is often avoided due to safety concerns. This systematic review summarizes the safety, feasibility and efficacy of exercise in controlled trials that include individuals with bone metastases. METHODS: MEDLINE, Embase, Pubmed, CINAHL, PEDro and CENTRAL databases were searched to July 16, 2020. RESULTS: A total of 17 trials were included incorporating aerobic exercise, resistance exercise or soccer interventions. Few (n = 4, 0.5%) serious adverse events were attributed to exercise participation, with none related to bone metastases. Mixed efficacy results were found, with exercise eliciting positive changes or no change. The majority of trials included an element of supervised exercise instruction (n = 16, 94%) and were delivered by qualified exercise professionals (n = 13, 76%). CONCLUSIONS: Exercise appears safe and feasible for individuals with bone metastases when it includes an element of supervised exercise instruction.

PURPOSE: Exercise is efficacious for people living after a cancer diagnosis. However, implementation of exercise interventions in real-world settings is challenging. Implementation outcomes are defined as 'the effects of deliberate and purposive actions to implement new treatments, practices, and services'. Measuring implementation outcomes is a practical way of evaluating implementation success. This systematic review explores the implementation outcomes of exercise interventions evaluated under real-world conditions for cancer care. METHODS: Using PRISMA guidelines, an electronic database search of Medline, PsycInfo, CINAHL, Web of Science, SportsDiscus, Scopus and Cochrane Central Registry of Controlled Trials was conducted for studies published between January 2000 and February 2020. The Moving through Cancer registry was hand searched. The Implementation Outcomes Framework guided data extraction. Inclusion criteria were adult populations with a cancer diagnosis. Efficacy studies were excluded. RESULTS: Thirty-seven articles that described 31 unique programs met the inclusion criteria. Implementation outcomes commonly evaluated were feasibility (unique programs n = 17, 54.8%) and adoption (unique programs n = 14, 45.2%). Interventions were typically delivered in the community (unique programs n = 17, 58.6%), in groups (unique programs n = 14, 48.3%) and supervised by a qualified health professional (unique programs n = 14, 48.3%). Implementation outcomes infrequently evaluated were penetration (unique programs n = 1, 3.2%) and sustainability (unique programs n = 1, 3.2%). CONCLUSIONS: Exercise studies need to measure and evaluate implementation outcomes under real-world conditions. Robust measurement and reporting of implementation outcomes can help to identify what strategies are essential for successful implementation of exercise interventions. IMPLICATIONS FOR CANCER SURVIVORS: Understanding how exercise interventions can be successful implemented is important so that people living after a cancer diagnosis can derive the benefits of exercise.

OBJECTIVE: To describe glioblastoma patients' and carers' perspectives of participating in a tailored exercise intervention during chemoradiotherapy. METHODS: A pilot study was conducted to evaluate if exercise was a feasible and safe therapy in patients with glioblastoma undergoing chemoradiotherapy. Patients received a supervised exercise intervention involving an individualised prescription of moderate-intensity aerobic and resistance exercise twice weekly, performed at the hospital when they attended for treatment. Semi-structured interviews were conducted with participants and their carers. Recordings were analysed using thematic analysis. RESULTS: 19 patients and 15 carers participated. Benefits and challenges of participating in the exercise intervention were described. Benefits included an individually tailored exercise program, improvements in health, regaining a sense of control, interacting with people, keeping active and benefits for carers. Challenges included managing symptoms associated with diagnosis and treatment, juggling treatment and exercise, and difficulties engaging in the program. CONCLUSION: Patients and carers expressed positive perceptions and experiences of participating in exercise during chemoradiotherapy; however, some challenges were experienced. These results support the quantitative pilot study which demonstrated that supervised exercise is feasible, safe and well tolerated by patients receiving chemoradiotherapy for glioblastoma. Randomised controlled trials now need to be conducted with this population.

BACKGROUND: Growing evidence suggests that men exposed to androgen deprivation therapy (ADT) have an increased risk of cardiovascular disease. While exercise has shown to attenuate some adverse effects of ADT, the effects on cardiometabolic health have not been systematically evaluated. OBJECTIVE: To evaluate the effect of exercise on cardiometabolic health in men with prostate cancer (PCa) receiving ADT. METHODS: A systematic literature search of MEDLINE, EMBASE, CINHAL, SCOPUS, WEB OF SCIENCE and SPORTSDICUS from database inception to April 2020 was performed. A quantitative synthesis using Cohens d effect size and a meta-analysis using random-effects models were conducted. RESULTS: Overall, fourteen randomised controlled trials (RCTs) and four non-randomised studies were included. Eleven RCTs (n = 939 patients) were included in the meta-analysis. Exercise training improved the 400-m-walk test (MD -10.11 s, 95% CI [-14.34, -5.88]; p < 0·00001), diastolic blood pressure (-2.22 mmHg, [-3.82, -0.61]; p = 0.007), fasting blood glucose (-0.38 mmol/L, [-0.65, -0.11]; p = 0.006), C-reactive protein (-1.16 mg/L, [-2.11, -0.20]; p = 0.02), whole-body lean mass (0.70 kg, [0.39, 1.01]; p < 0.0001), appendicular lean mass (0.59 kg, [0.43, 0.76]; p < 0.00001), whole-body fat mass (-0.67 kg, [-1.08, -0.27]; p = 0.001), whole-body fat percentage (-0.79%, [-1.16, -0.42]; p < 0.0001), and trunk fat mass (-0.49 kg, [-0.87, -0.12]; p = 0.01), compared to usual care. No significant effects on systolic blood pressure or blood lipid metabolism were detected. CONCLUSIONS: In a small subset of evaluated studies, exercise may favourably improve some but not all markers of cardiometabolic health. Future exercise intervention trials with cardiometabolic outcomes as primary endpoints are needed to confirm these initial findings.

BACKGROUND: Cancer cachexia is a muscle-wasting syndrome that results in physical function impairments and decreased survival. While body weight and muscle mass loss predict survival, the prognostic significance of physical function in this population is unclear. Thus, we evaluated the association between physical function, and other routine measures, and overall survival (OS) in cancer patients attending a cachexia support service. METHODS: Physical function was clinically-assessed using the 30 s sit-to-stand test and handgrip strength. Six-month weight loss, the Patient-Generated Subjective Global Assessment (PG-SGA) total score, C-reactive protein (CRP), albumin, and quality of life were also evaluated. RESULTS: Records from 203 patients (age: 68.6 ± 11.6 years) were included. Handgrip strength did not predict OS. Sit-to-stand repetitions predicted OS in the single variable, but not the multivariable analysis. Multivariable results suggested higher PG-SGA total scores (HR: 1.04, 95% CI: 1.01-1.07), six-month weight loss (HR: 1.02, 95% CI: 1.004-1.04), and elevated CRP (HR: 1.004, 95% CI: 1.0004-1.01) predicted shorter OS. Higher albumin predicted longer OS (HR: 0.93, 95% CI: 0.90-0.97). CONCLUSION: Six-month weight loss, the PG-SGA total score, CRP, and albumin independently predicted survival, while physical function did not. Functional impairments remain a hallmark of cancer cachexia and the benefit of their routine assessment warrants further exploration, especially in relation to patient quality of life.

BACKGROUND: Every four minutes, an Australian is diagnosed with cancer. Early detection and effective treatment means that many of these people are living with the side effects of cancer and its treatment for numerous years. OBJECTIVE: The aim of this article is to summarise the evidence examining the role of exercise in cancer care. DISCUSSION: Exercise is a safe and effective adjunct therapy in cancer care. Patients with cancer who regularly engage in moderate-intensity exercise are more likely to have: fewer and less severe treatment-related side effects; a lower relative risk of developing other chronic diseases; and, in some cases, a lower relative risk of cancer recurrence and mortality. Available evidence highlights the benefits of general practitioners (GPs) discussing and recommending exercise to their patients with cancer. To optimise the therapeutic effect of exercise, GPs may consider referring patients with cancer to an exercise physiologist or physiotherapist who has experience in cancer care.

Androgen deprivation therapy (ADT) is associated with considerable adverse side effects which compromise the health and wellbeing of many men with prostate cancer. Exercise has been identified as a therapy to help manage ADT-related treatment toxicities. This paper systematically reviews the scientific literature investigating the impact of exercise on men receiving ADT and discusses strategies to effectively implement exercise in clinical practice. The findings of this review demonstrate that exercise has therapeutic benefit for the management of ADT-related side effects. Significant positive effects following exercise were observed for aerobic fitness, muscular strength, physical function, body composition, fatigue, sexual wellbeing, mental wellbeing, social function, comorbid disease risk factors, and quality of life. Emerging evidence suggests exercise may also play a role in managing bone loss, cognitive decline, and urinary problems, and may be delivered without exacerbating bone pain. Exercise did not negatively influence ADT treatment efficacy and led to few adverse events of minor severity, rendering it a safe intervention for men receiving ADT. To maximize the therapeutic effect of exercise, men with prostate cancer should participate in moderate-to-high intensity aerobic, resistance and impact exercise which is prescribed and supervised by a qualified exercise physiologist and delivered at a convenient location in a prostate cancer specific group-based environment. The level of evidence now available supports the view that the prescription of exercise medicine should be part of routine prostate cancer care.

Exercise is an efficacious therapy for many chronic diseases. Integrating efficacious evidence-based interventions (EBIs), such as exercise, into daily healthcare practice is a slow and complex pursuit. Implementation science seeks to understand and address this phenomenon by conducting studies about the methods used to promote the routine uptake of EBIs. The purpose of this article is to explore implementation science and a common conceptual framework in the discipline, the Consolidated Framework for Implementation Research (CFIR), as it applies to exercise EBI. We conclude by offering recommendations for future research that leverage implementation science priorities to highlight the potential of this research field for advancing the implementation of exercise EBI.

PURPOSE: Regular exercise is recommended to mitigate the adverse effects of androgen deprivation therapy in men with prostate cancer. The purpose of this study was to explore the experience of transition to unsupervised, community-based exercise among men who had participated in a hospital-based supervised exercise programme in order to propose components that supported transition to unsupervised exercise. METHODS: Participants were selected by means of purposive, criteria-based sampling. Men undergoing androgen deprivation therapy who had completed a 12-week hospital-based, supervised, group exercise intervention were invited to participate. The programme involved aerobic and resistance training using machines and included a structured transition to a community-based fitness centre. Data were collected by means of semi-structured focus group interviews and analysed using thematic analysis. RESULTS: Five focus group interviews were conducted with a total of 29 men, of whom 25 reported to have continued to exercise at community-based facilities. Three thematic categories emerged: Development and practice of new skills; Establishing social relationships; and Familiarising with bodily well-being. These were combined into an overarching theme: From learning to doing. Components suggested to support transition were as follows: a structured transition involving supervised exercise sessions at a community-based facility; strategies to facilitate peer support; transferable tools including an individual exercise chart; and access to 'check-ups' by qualified exercise specialists. CONCLUSIONS: Hospital-based, supervised exercise provides a safe learning environment. Transferring to community-based exercise can be experienced as a confrontation with the real world and can be eased through securing a structured transition, having transferable tools, sustained peer support and monitoring.
