This study aimed to investigate the accuracy and reliability of accelerometer-based pedometers placed on the wrist, waist, and shoe's midsole during walking, running, and stair climbing. Twenty healthy adults were recruited. Steps were recorded by the pedometers and visually assessed from simultaneously recorded video to evaluate the accuracy of each pedometer in different locations of attachment. One week later, steps were recorded again by the pedometers only to evaluate the reliability of each pedometer in different locations of attachment. The wrist-worn pedometer presented significantly greater error scores compared to the midsole-worn pedometer during walking (p < 0.001), running (p = 0.006), and stair climbing (p = 0.003). Additionally, mean absolute precent error and Bland-Altman plots indicated that the pedometer worn in the midsole was most accurate for running and stair climbing, followed by waist-worn and wrist-worn pedometers. Furthermore, the midsole-worn and waist-worn pedometers showed strong reliability during walking and running, but only the midsole-worn pedometer presented acceptable reliability during stair climbing. The pedometer's position impacts the accuracy and reliability of step counts, especially for walking and stair climbing. Embedding the pedometer into the midsole seems an effective approach to improve the accuracy and reliability of step counts. [ABSTRACT FROM AUTHOR]

The trial aimed to examine the effect of eight weeks preoperative low‐load blood flow restricted resistance training (BFR‐RT) on physical function, lower limb strength, and patient‐reported outcomes in knee OA patients 3 and 12 months after total knee arthroplasty (TKA) compared with preoperative usual care. An assessor blinded randomized controlled trial (RCT) was conducted. Eighty‐six patients scheduled for TKA who were allocated to 8 weeks BFR‐RT on the affected leg 3x/week or preoperative usual care involving no exercise (CON). Primary outcome: 30‐s sit to stand (30STS). Secondary outcomes: Timed Up&Go, 40‐m walk test (40mWT), knee range of motion (ROM) 1‐repetition maximum (1RM) leg press and knee extensor strength, maximal isometric contraction (MVIC) for the knee extensors and flexors, Knee injury and Osteoarthritis Outcome Score (KOOS), and Euroqol 5‐dimensions (EQ‐5D‐L5) questionnaire. Data were collected at baseline (12 weeks pre‐surgery), ~3 days pre‐surgery, 3 and 12 months postoperatively. Intention‐to‐treat analysis revealed no significant between‐group differences in the change from baseline to 3 and 12 months postoperatively on 30STS, TUG, or 40mFWT. Significant between‐group differences were observed at 3 but not 12 months postoperatively for the corresponding changes in 1RM leg press strength, 1RM knee extensor strength, and MVIC knee extensor favoring BFR‐RT. No between‐group differences were observed for the delta changes from baseline in knee ROM, KOOS subscales or EQ‐5D‐L5 at any postoperative time points. These findings suggest that preoperative BFR‐RT offered no superior effects compared with usual preoperative care on postoperative physical function or patient‐reported outcomes. Preoperative BFR‐RT produced amplified gains in lower limb muscle strength at 3 months postoperatively. Trial Registration: NCT04081493 [ABSTRACT FROM AUTHOR]

Objective: Assessment of physical activity and exercise prescription has been widely supported by many organizations, yet provision of such services remains limited in the United States. We sought to uncover why such services have not been widely adopted. Design: The American Medical Society for Sports Medicine organized a task force to canvas physicians and survey the American Medical Society for Sports Medicine membership. Setting: Peer-to-peer and telecommunication discussions and webbased questionnaires. Participants: Sports medicine physicians in the United States. Interventions: None. MainOutcome Measures: Percentage of sports medicine physicians who provide exercise management services and mechanisms of billing for exercise management, identify barriers to such services, and identify industry collaborations for promoting physical activity through physicians. Results: Three of 4 sports medicine physicians spend at least 1 min encouraging exercise with patients, using Evaluation and Management codes to bill or receive credit. Exercise counseling is often bundled within other patient care. Few health plans leverage the patient’s relationship with a primary care physician to promote exercise. Most employed sports medicine physicians do not receive incentives to incorporate exercise counseling into practice, and only 1 in 6 have decision-making authority to hire an exercise professional. Major obstacles are the lack of a business model and knowledge about exercise prescription. Conclusion: The existing E&M codes adequately characterize the work, but physicians desire greater payment or credit for providing exercise management services. Physicians desire to do more exercise prescription, but health system bureaucracy, inadequate support, and economic disincentives are barriers to the provision of exercise management services.

Introduction: Arterial hypertension is a global health burden that affects vascular structure and function. Assessment of endothelial function can improve cardiovascular (CV) risk stratification. Exercise treatment reduces over all CV risk and improves vascular health. However, it is still not clear which part of the vascular bed is most sensitive to exercise treatment in patients with CV risk. This study aimed to investigate the effects of an 8‐week walking based and supervised high‐intensity interval training (HIIT) on macro‐ and microvascular endothelial function as add‐on therapy in patients with arterial hypertension. Methods: Forty patients (mean age 58 ± 7 years) treated for arterial hypertension were randomized in the HIIT (3×/week) or control group (CG) receiving standard physical activity recommendations. Arteriolar (aFID) and venular (vFID) flicker light‐induced dilatation for retinal microvascular and flow‐mediated dilatation (FMD) for macrovascular endothelial function were assessed. In addition, standardized assessments of patients' characteristics were performed before and after 8 weeks. Results: Both groups reduced weight and body mass index but only the HIIT group reduced body fat, visceral fat, and increased peak oxygen uptake after 8 weeks. The control group reduced diastolic blood pressure. No blood pressure changes were found in the HIIT group. Arteriolar FID increased in the HIIT group independently of confounders (pre: 2.40 ± 0.98%, post: 3.19 ± 1.31%, p < 0.001) but not in the control group (pre: 3.06 ± 1.50%, post: 2.90 ± 1.46%, p = 0.280). No changes were found for FMD in either group. Conclusion: Arteriolar FID was found to be a sensitive vascular biomarker to assess exercise‐induced microvascular improvements even in a short time setting of an 8‐week exercise therapy with HIIT. Short‐term exercise training affects microvascular endothelial function but not large artery endothelial function. Thus, retinal aFID appears to be a sensitive biomarker to detect short‐term exercise efficacy on a vascular level. Dynamic retinal vessel analysis as a diagnostic approach may prove to be an ideal candidate vascular biomarker to monitor treatment effects of exercise in patients with hypertension on top of standard clinical care and may support clinical decision‐making in the future.

Introduction: Men who receive androgen deprivation therapy (ADT) for prostate cancer (PCa) are a vulnerable falls population due to the side effects of treatment. The purpose of this paper is to determine the cost-effectiveness of exercise in preventing falls and fractures for this high-risk population in Australia.Methods: A decision analytic model was constructed to evaluate the cost utility of an exercise intervention compared to usual care from a health system perspective. The intervention comprised two 1-h sessions of supervised exercise per week over 1 year for men with non-metastatic PCa receiving curative radiation therapy and ADT. A Markov model simulated the transition between five health states: (1) at risk of falling; (2) at recurrent risk of falling; (3) fracture (minor or major); (4) non-fracture injury (minor or major); and (5) death. Model inputs including transition probabilities and utility scores were obtained from published meta-analyses, and costs were drawn from Australian data sources (e.g. Medical Benefits Schedule). The model time horizon was 3 years, and costs and effects were discounted at 5% annual rate. Costs and quality-adjusted life years (QALYs) were aggregated and compared between the intervention and control to calculate incremental net monetary benefit (iNMB). Uncertainty in the results was explored using deterministic and probabilistic sensitivity analyses (PSA).Results: At a willingness-to-pay of AU$50,000 per QALY, the exercise intervention dominated, as it was less costly and more effective than usual care. The iNMB was $3010 per patient. The PSA showed a 58% probability the intervention was cost-effective.Conclusion: This is the first modelled economic evaluation of exercise for men with PCa. Our results suggest supervised exercise is cost-effective in reducing the risks of falls and fractures in this population. [ABSTRACT FROM AUTHOR]

The article focuses on prostate cancer (PCa) patients with bone metastases tend to have significant functional impairment from long-term androgen deprivation therapy, exacerbated by subsequent treatments such as second-line hormone therapies, first-and second-line chemotherapy or immunotherapies. Topics include the effectiveness of exercise in addressing the adverse effects of advanced PCa treatment, and the clinicians or patients due to concerns of fragility fracture or other adverse effects.

Prostate cancer (PCa) affects 1 in 8 men, but exercise therapy has been shown to be a very effective intervention not only to induce physiological benefits but to also reduce the side effects of cancer treatments typically administered during PCa. The COVID19 pandemic has restricted access to exercise clinics, a problem which always existed for people living in rural and remote areas. This caused many exercise physiologists and researchers to transition their clinic-based exercise to online, home-based exercise. We would like to propose that researchers and exercise physiologists should consider the use of elastic tubes in both research and the clinical management of PCa, when exercise programs are administered remotely, as their characteristics make them an ideal exercise equipment. In this article, the characteristics, considerations, and information on quantifying exercise dosage when using elastic tubes in remote exercise delivery are discussed. [ABSTRACT FROM AUTHOR]

Purpose: Prostate cancer (PCa) is the most commonly diagnosed cancer in Australia, accounting for one quarter of all new cancer diagnoses for males. Androgen deprivation therapy (ADT) is the standard first-line therapy for metastatic PCa but is also used across much of the spectrum of disease. Unfortunately, debilitating adverse effects are a significant and largely unavoidable feature of ADT. A recent systematic review of adverse effects of ADT identified 19 sub-groups classified according to the Common Terminology Criteria for Adverse Events (CTCAE) Version 5.0. The potential for multiple simultaneous adverse effects, their associated management and the impact of adverse effects on cancer outcomes and quality of life are important considerations in the treatment and supportive care of men with PCa. Exercise is increasingly being recognized as an efficacious strategy in managing these adverse effects.Methods: A rapid review was undertaken to examine the role of exercise in the management of the most commonly reported ADT adverse effects classified according to the CTCAE sub-groups. A systematic search was conducted in Medline, PsycINFO, Google Scholar and Google for the years 2010 to September 2019 to identify the benefits of exercise in managing the adverse effects of ADT for PCa.Results: There is strong evidence for exercise as medicine in addressing several of the adverse effects of PCa such as loss of muscle mass and strength, fatigue and declining physical function. Moderate level evidence for PCa exists for exercise-induced improvements in depression and anxiety, bone loss, and sexual dysfunction. While evidence of the effectiveness of exercise is lacking for many adverse effects of ADT for PCa, evidence in the cancer population as a whole or other clinical populations is strong, and many clinical guidelines recommend exercise as a fundamental part of their clinical management. With the exception of gynaecomastia and breast pain, there is increasing evidence (PCa, cancer or other clinical populations) to suggest that exercise has the potential to reduce and even prevent many of the adverse effects of ADT, thus improving survivorship outcomes for men with PCa.Conclusion: Exercise has the potential to reduce and even prevent many of the adverse effects of ADT, thus improving survivorship outcomes for men with PCa. The use of exercise for PCa management has the potential to translate into health and economic benefits in improved quality of life and fewer complications, resulting in savings to the health care system, enhanced productivity and reduced patient and carer burden. Exercise thus has the potential to improve quality of life for this population as well as generate significant cost savings. [ABSTRACT FROM AUTHOR]

Purpose: Exercise is generally accepted to be beneficial for colorectal cancer patients; however, very few studies have investigated the effects of exercise on patient care and health outcomes during the immediate post-operative recovery period. Furthermore, very few studies have investigated the safety, feasibility, and efficacy of exercise on post-operative cancer patients. Although intervention programs should be based on solid evidence from clinical trials, the majority of previous studies have not presented the development process of the intervention programs. This paper describes a ten-step development process of an inpatient exercise program for colorectal cancer patients after colectomy.Methods: The development process is composed of the following ten steps: systematic literature review, understanding patient characteristics via patient survey, first expert group discussion, development of the first draft exercise program, pretest, focus group interview, second expert group discussion, pilot study, randomized controlled trial, and the final exercise program development.Results: The exercise program developed through the ten-step process was divided into three phases according to the patients' condition. For all three phases, patients performed the exercises two times a day, once under supervision. Any specific exercises that caused pain on a given day were excluded from the exercise program for that day. The exercise program reduced the length of hospital stay and time to flatus in colorectal cancer patients after surgery.Conclusion: This study reports a safe and effective means to develop an evidence-based exercise program not only for colorectal cancer patients but also for other population groups.

Objective: Sub-maximal aerobic exercise can alleviate brain injury-related symptom burden. There is substantial data from animal studies and a growing clinical evidence base to suggest that exercise may also improve cognitive and neural outcomes following brain injury. We performed this systematic review to consolidate evidence from randomized and controlled clinical trials on the effects of exercise on cognitive and neuroimaging outcomes following brain injury in humans. Design: Systematic review. Data sources: MEDLINE, EMBASE, PsychINFO, CINAHL, SPORTDiscus, and Cochrane Central Database. Eligibility criteria for screening studies: Randomized or controlled clinical trials examining the effects of exercise on cognitive and/or neuroimaging outcomes in traumatic brain injury. No restriction was placed on age (or other demographic variables) or severity of injury. Results: Six studies (with an average sample of 42 participants) met eligibility criteria. Three studies used neuroimaging and reported exercise-related improvements as measured by either functional or diffusion-based imaging. The remainder of the trials that employed cognitive outcomes reported largely null findings. Summary/Conclusion: This review demonstrates that exercise shows promise (primarily with respect to neuroimaging outcomes) as a brain injury intervention. While the field is young and heterogeneity between studies precludes meta-analysis, this review raises important questions that need to be addressed by future trials. [ABSTRACT FROM AUTHOR]

Aim: Given the time spent at work, the workplace represents an ideal setting to implement preventive programs for non-communicable diseases, the major cause of mortality and morbidity in Western and developing countries. We sought to verify if an ecological approach based on corporate culture, employees' education and concrete modifications of workplace environment, offering easy opportunity to assume healthy lifestyle, could be associated with reduced cardiometabolic risk. Methods: The study involved 1089 workers in two multinational companies following different workplace health promotion policies. Company A offered to all employees the opportunity to access a web platform dedicated to general information on health and diseases. Company B implemented an ecological model encompassing company culture, employees' education and concrete modifications of workplace environment, giving to all employees the opportunity to adopt healthy solutions throughout daily living at workplace. Participants volunteered self-reported clinical information using an IT tool. Numbers of Metabolic Syndrome components (MetS) were taken as proxy of cardiometabolic risk. Results: MetS probability obtained via statistical modeling was lower in company B as compared to company A, and absenteeism was also lower in company B. Our study shows that a work environment favoring assumption of healthy lifestyle, as in company B, is associated with a lower percentage of employees with MetS components and lower absenteeism. Moreover, statistical modeling shows that individual probabilities of being without MetS elements, controlling for age and gender, is remarkably higher in company B. Conclusions: Our data suggest that ecological approaches might be useful in worksite prevention policies. [ABSTRACT FROM AUTHOR]

Introduction: Aerobic fitness seems to provide extra protection to the cardiovascular system beyond changing the traditional risk factors, a phenomenon referred to as the risk factor gap model. Aerobic fitness may possibly lead to improved autonomic regulation. The Task Force of the American Heart Association supports a national campaign to reach specific cardiovascular health goals considering various metrics, including recommended physical activity (PA) volumes. It may be clinically relevant to assess whether autonomic remodeling occurs in those who adhere to the PA recommendations. Methods: We studied 39 healthy subjects (22 males and 17 females), subdivided into two groups, according to whether they were meeting or not meeting PA recommendations (150 min/week of moderate aerobic activity, or 75 min/week of vigorous aerobic activity, or a combination of both). For each group, we evaluated aerobic capacity (VO Peak), body composition (Fat Mass) and autonomic nervous system profile, by way of mono and bivariate spectral analysis of cardiovascular beat by beat variability. Results: Subjects following PA recommendations show higher RR period, higher RR variance, greater absolute power of the respiratory component of RR variability (HF) and higher index alpha (a measure of spontaneous baroreflex). Moreover, as expected, the group that was meeting or exceeding current PA recommendations had higher VO peak, less fat mass and greater weekly energy expenditure. Conclusion: Data show that subjects meeting current PA recommendations present a phenotype suggestive of enhanced parasympathetic drive to the SA node. This finding is compatible with the hypothesis that a more favorable autonomic profile is part of the mechanisms of the risk factor gap. [ABSTRACT FROM AUTHOR]

The aim of this study was to identity the types of physical activity narratives drawn upon by active spinal injured people. More than 50 h of semi-structured life-story interview data, collected as part of larger interdisciplinary program of disability lifestyle research, was analysed for 30 physically active male and female spinal cord injury (SCI) participants. A structural narrative analysis of data identified three narrative types which people with SCI draw on: (1) exercise is restitution, (2) exercise is medicine, and (3) exercise is progressive redemption. These insights contribute new knowledge by adding a unique narrative perspective to existing cognitive understanding of physical activity behaviour in the spinal cord injured population. The implications of this narrative typology for developing effective positive behavioural change interventions are critically discussed. It is concluded that the identified narratives types may be constitutive, as well as reflective, of physical activity experiences and therefore may be a useful tool on which to base physical activity promotion initiatives.

Aim: This systematic review aimed to explore the literature to identify in which types of chronic diseases exercise with supplemental oxygen has previously been utilized and whether this type of personalized therapy leads to superior effects in physical fitness and well-being. Methods: Databases (PubMed/MEDLINE, CINHAL, EMBASE, Web of knowledge and Cochrane Library) were searched in accordance with PRISMA. Eligibility criteria included adult patients diagnosed with any type of chronic diseases engaging in supervised exercise training with supplemental oxygen compared to normoxia. A random-effects model was used to pool effect sizes by standardized mean differences (SMD). Results: Out of the identified 4038 studies, 12 articles were eligible. Eleven studies were conducted in chronic obstructive pulmonary disease (COPD), while one study included coronary artery disease (CAD) patients. No statistical differences were observed for markers of physical fitness and patient-reported outcomes on well-being between the two training conditions (SMD −0.10; 95% CI −0.27, 0.08; p = 0.26). Conclusions: We found that chronic exercise with supplemental oxygen has mainly been utilized for COPD patients. Moreover, no superior long-term adaptations on physical fitness, functional capacity or patient-reported well-being were found, questioning the role of this method as a personalized medicine approach.

Background: Skeletal metastases present a major challenge for clinicians, representing an advanced and typically incurable stage of cancer. Bone is also the most common location for metastatic breast carcinoma, with skeletal lesions identified in over 80% of patients with advanced breast cancer. Preclinical models have demonstrated the ability of mechanical stimulation to suppress tumour formation and promote skeletal preservation at bone sites with osteolytic lesions, generating modulatory interference of tumour-driven bone remodelling. Preclinical studies have also demonstrated anti-cancer effects through exercise by minimising tumour hypoxia, normalising tumour vasculature and increasing tumoural blood perfusion. This study proposes to explore the promising role of targeted exercise to suppress tumour growth while concomitantly delivering broader health benefits in patients with advanced breast cancer with osteolytic bone metastases.Methods: This single-blinded, two-armed, randomised and controlled pilot study aims to establish the safety, feasibility and efficacy of an individually tailored, modular multi-modal exercise programme incorporating spinal isometric training (targeted muscle contraction) in 40 women with advanced breast cancer and stable osteolytic spinal metastases. Participants will be randomly assigned to exercise or usual medical care. The intervention arm will receive a 3-month clinically supervised exercise programme, which if proven to be safe and efficacious will be offered to the control-arm patients following study completion. Primary endpoints (programme feasibility, safety, tolerance and adherence) and secondary endpoints (tumour morphology, serum tumour biomarkers, bone metabolism, inflammation, anthropometry, body composition, bone pain, physical function and patient-reported outcomes) will be measured at baseline and following the intervention.Discussion: Exercise medicine may positively alter tumour biology through numerous mechanical and non-mechanical mechanisms. This randomised controlled pilot trial will explore the preliminary effects of targeted exercise on tumour morphology and circulating metastatic tumour biomarkers using an osteolytic skeletal metastases model in patients with breast cancer. The study is principally aimed at establishing feasibility and safety. If proven to be safe and feasible, results from this study could have important implications for the delivery of this exercise programme to patients with advanced cancer and sclerotic skeletal metastases or with skeletal lesions present in haematological cancers (such as osteolytic lesions in multiple myeloma), for which future research is recommended.Trial Registration: anzctr.org.au , ACTRN-12616001368426 .
