The human ageing process is universal, ubiquitous and inevitable. Every physiological function is being continuously diminished. There is a range between two distinct phenotypes of ageing, shaped by patterns of living - experiences and behaviours, and in particular by the presence or absence of physical activity (PA) and structured exercise (i.e., a sedentary lifestyle). Ageing and a sedentary lifestyle are associated with declines in muscle function and cardiorespiratory fitness, resulting in an impaired capacity to perform daily activities and maintain independent functioning. However, in the presence of adequate exercise/PA these changes in muscular and aerobic capacity with age are substantially attenuated. Additionally, both structured exercise and overall PA play important roles as preventive strategies for many chronic diseases, including cardiovascular disease, stroke, diabetes, osteoporosis, and obesity; improvement of mobility, mental health, and quality of life; and reduction in mortality, among other benefits. Notably, exercise intervention programmes improve the hallmarks of frailty (low body mass, strength, mobility, PA level, energy) and cognition, thus optimising functional capacity during ageing. In these pathological conditions exercise is used as a therapeutic agent and follows the precepts of identifying the cause of a disease and then using an agent in an evidence-based dose to eliminate or moderate the disease. Prescription of PA/structured exercise should therefore be based on the intended outcome (e.g., primary prevention, improvement in fitness or functional status or disease treatment), and individualised, adjusted and controlled like any other medical treatment. In addition, in line with other therapeutic agents, exercise shows a dose-response effect and can be individualised using different modalities, volumes and/or intensities as appropriate to the health state or medical condition. Importantly, exercise therapy is often directed at several physiological systems simultaneously, rather than targeted to a single outcome as is generally the case with pharmacological approaches to disease management. There are diseases for which exercise is an alternative to pharmacological treatment (such as depression), thus contributing to the goal of deprescribing of potentially inappropriate medications (PIMS). There are other conditions where no effective drug therapy is currently available (such as sarcopenia or dementia), where it may serve a primary role in prevention and treatment. Therefore, this consensus statement provides an evidence-based rationale for using exercise and PA for health promotion and disease prevention and treatment in older adults. Exercise prescription is discussed in terms of the specific modalities and doses that have been studied in randomised controlled trials for their effectiveness in attenuating physiological changes of ageing, disease prevention, and/or improvement of older adults with chronic disease and disability. Recommendations are proposed to bridge gaps in the current literature and to optimise the use of exercise/PA both as a preventative medicine and as a therapeutic agent.

BACKGROUND: The concept of frailty has been suggested to comprise physical, mental, and social phenotypes. However, there is no general consensus about the appropriate components for assessing frailty. OBJECTIVES: The purpose of this study was to reach consensus on components of frailty assessment using the Delphi process. METHODS: To achieve consensus on the definition of frailty, a modified Delphi method was used. Geriatric and gerontologic experts were selected from various fields. The detailed components of frailty were composed of data from the Korean Frailty and Aging Cohort Study. Establishing consensus and collecting opinions from experts were conducted using a modified Delphi method. RESULTS: Overall, nine domains with 14 components of frailty assessment were accepted. There was consensus on the necessity of a broad phenotype including physical, mental, and social frailty. CONCLUSIONS: Consensus on the components of a frailty assessment in a clinical setting is achieved through the Delphi process to establish a new tool of frailty assessment.

BACKGROUND: SARC-F is recommended as a sarcopenia screening tool and comprised of five assessment items: strength, assistance walking, rising from a chair, climbing stairs, and falls. OBJECTIVE: The purpose of this study was to assess whether the SARC-F questionnaire in elderly patients with hip fractures was a valid screening tool for sarcopenia by comparison of the results with criteria from the Europe, Asia, and international working groups. MEASUREMENTS: 115 men and woman with hip fractures were assessed. The SARC-F self-reported questionnaire scores range from 0 to 10 and a score ≥ 4 defines sarcopenia. These survey questions were used to calculate the SARC-F score. Measurements, including appendicular muscle mass, were taken using dual-energy X-ray and grip strength using a dynamometer. Classification using the SARC-F score was compared using the consensus panel criteria from the international, European, and Asian sarcopenia working groups. The performance of all four methods was compared by examining the predictive ability using a ROC curve. RESULTS: A total of 115 subjects were included and the sarcopenia prevalence rate (SARC-F score ≥ 4) was 63.5 percent. The sensitivity, specificity, positive predictive value, negative predictive value PPV with the EWGSOP-2 criteria in Older People as the reference standard were 95.35 %, 56.94 %, 56.94%, 95.35%, and 71.3%, respectively. In addition, we found similar results for sensitivity and specificity as studies using the EWGSOP and AWGS criteria. CONCLUSIONS: The SARC-F questionnaire is a useful screening tool for elderly patients with hip fractures. This finding supports the recommendation of SARC-F as a screening tool for sarcopenia from the EWGSOP2.
