Abstract Objectives: To describe the normative values of sarcopenia among community-dwelling adults (≥21), compare the prevalence of sarcopenia using AWGS2014, AWGS2019 and EWGSOP2 guidelines, and identify factors associated with sarcopenia.Design: Participants were recruited through random sampling. Sarcopenia assessments were performed using a DXA scan (muscle mass), handgrip test (muscle strength) and usual walking test (physical performance). Questionnaires were administered to evaluate lifestyle and cognition.Setting and Participants: 542 community-dwelling Singaporeans were recruited (21-90 years old, 57.9% women). Methods: We assessed anthropometry, body composition, and questionnaire-based physical and cognitive factors, and estimated sarcopenia prevalence according to the AWGS2014, AWGS2019 and EWGSOP2 recommendations, and examined associations using logistic regression.Results: According to AWGS2019, the Singapore population-adjusted sarcopenia prevalence was 13.6% (men 13.0%; women 14.2%) overall, and 32.2% (men 33.7%, women 30.9%) in those aged 60 and above. The cut-offs derived from young adult reference group for low ALMI is 5.28 kg/m2 for men and 3.69 kg/m2 for women (lower than AWGS recommended cut-off); for GS it is 0.82 m/s, (AWGS2019 recommended cut-off 1.0m/s, AWGS2014 cut-off was 0.8 m/s); for HGS, it is 27.9 kg /m2 for men, and 16.7 kg/m2 for women (close to AWGS2019 recommendation). Age, gender, marital status, alcoholism, physical activity, BMI, waist circumference and global cognition were associated with sarcopenia (p<.05).Conclusions and Implications: This is the first study to provide reference values of muscle mass, strength and gait speed across the adult lifespan of Singaporeans. Using AWGS2019 criteria, sarcopenia is prominent in older age (32.2% in ≥60 years old); but it is already non-trivial (6.9%) among young and middle-aged persons. Multi-domain lifestyle modifications addressing muscle strength, cognition and nutrition over the adult lifespan is important to delay the development of sarcopenia.

Abstract Background in October 2018, the European Working Group on Sarcopenia in Older People 2 (EWGSOP2) updated their original definition of sarcopenia to reflect the scientific and clinical evidence that has accumulated over the last decade. Objective to determine the prevalence of sarcopenia in a large group of community-dwelling older adults using the EWGSOP2 definition and algorithm. Design a cross-sectional study. Setting the nationwide Korean Frailty and Aging Cohort Study (KFACS). Subjects a total of 2,099 ambulatory community-dwelling older adults, aged 70–84 years (mean age, 75.9 ± 4.0 years; 49.8% women) who were enrolled in the KFACS. Methods physical function was assessed by handgrip strength, usual gait speed, the five-times-sit-to-stand test, the timed up-and-go test, and the Short Physical Performance Battery. Appendicular skeletal muscle mass (ASM) was measured by dual-energy X-ray absorptiometry. Results according to the criteria of the EWGSOP2, the sarcopenia indicators of combined low muscle strength and low muscle quantity were present in 4.6–14.5% of men and 6.7–14.4% of women. The severe sarcopenia indicators of combined low muscle strength, low muscle quantity and low physical performance were present in 0.3–2.2% of men and 0.2–6.2% of women. Using the clinical algorithm with SARC-F as a screening tool, the prevalence of probable sarcopenia (2.2%), confirmed sarcopenia (1.4%) and severe sarcopenia (0.8%) was low. Conclusions the prevalence of sarcopenia among community-dwelling older individuals varied depending on which components of the revised EWGSOP2 definition were used, such as the tools used to measure muscle strength and the ASM indicators for low muscle mass.

Community Dwelling Older Adults

Aging is a global public health concern. From the age of 50, muscle mass, muscle strength and physical performance tend to decline. Sarcopenia and frailty are frequent in community-dwelling older adults and are associated with negative outcomes such as physical disability and mortality. Therefore, the identification of therapeutic strategies to prevent and fight sarcopenia and frailty is of great interest. This systematic review aims to summarize the impact of nutritional interventions alone or combined with other treatment(s) in older community-dwelling adults on (1) the three indicators of sarcopenia, i.e., muscle mass, muscle strength and physical performance; and (2) the hospitalization and readmission rates. The literature search was performed on Medline and included studies published between January 2010 and June 2020. We included randomized controlled trials of nutritional intervention alone or combined with other treatment(s) in community-living subjects aged 65 or older. In total, 28 articles were retained in the final analysis. This systematic review highlights the importance of a multimodal approach, including at least a combined nutritional and exercise intervention, to improve muscle mass, muscle strength and physical performance, in community-dwelling older adults but especially in frail and sarcopenic subjects. Regarding hospitalization and readmission rate, data were limited and inconclusive. Future studies should continue to investigate the effects of such interventions in this population.

AbstractSarcopenia is a muscle disease rooted in adverse muscle changes that accrue across a lifetime. It is an independent risk factor for numerous adverse health outcomes. In 2010, the European Working Group on Sarcopenia in Older People (EWGSOP) published a definition for the identification of people with sarcopenia (EWGSOP1). In 2018, this definition was updated based on the newest evidence (EWGSOP2), with the focus now on low muscle strength rather than low muscle quantity as the key characteristic of sarcopenia. In addition, EWGSOP2 provides clear cut-off points for measurements of variables that identify sarcopenia. The aim of this study was to determine the prevalence of sarcopenia among community-dwelling older adults in Ireland for the first time and to assess agreement between the EWGSOP1 and EWGSOP2 definitions. In a cross-sectional analysis, 490 community-dwelling adults (age 78.4 ± 8.0 y, body mass index 27.6 ± 5.1 kg/m2) were assessed. Skeletal muscle mass was estimated using bioelectrical impedance analysis, muscle strength was measured via handgrip dynamometry and physical performance via the Short Physical Performance Battery. Sarcopenia was defined according to both the 2010 criteria (EWGSOP1) and the updated 2018 criteria (EWGSOP2). Using the EWGSOP1 criteria, the prevalence of sarcopenia was 7.1% (2.6% sarcopenia, 4.5% severe sarcopenia) and 3.6% were classified as pre-sarcopenic (low muscle mass without a decrement in strength or physical performance). Using the EWGSOP2 criteria, the prevalence of sarcopenia was 5.5% (1.6% sarcopenia, 3.9% severe sarcopenia) and 23.4 % were classified as having low strength but without a decrement in muscle mass. Five of the participants who were classified as sarcopenic (2 sarcopenia, 3 severe sarcopenia) by EWGSOP1 were classified as “normal” using the EWGSOP2 criteria. In conclusion, the prevalence of sarcopenia in community-dwelling older adults in Ireland is in line with the prevalence reported in other European countries using the EWGSOP1 criteria (3.3–11.4 %). To our knowledge this is the first study to compare the prevalence based on the EWGSOP1 and the EWGSOP2 criteria. We report a slightly lower prevalence using the EWGSOP2 definition compared to the EWGSOP1 definition. Importantly however, in contrast to EWGSOP1, the EWGSOP2 definition identified a substantial proportion of older adults with poor strength in the absence of overt sarcopenia (23.4%). These older adults represent a group who would benefit from further clinical investigation and intervention.

ObjectiveTo examine the relationship between different measures of testosterone and estradiol (E2), muscle mass, muscle strength, and physical performance; and to test whether the association of sex hormone level with muscle strength and physical performance was independent of muscle mass.Design and methodsA cross-sectional survey on 1489 community-dwelling men older than 64 years of age. Serum levels of testosterone and E2were measured by mass spectrometry, and sex hormone-binding globulin (SHBG) levels were measured by immunoradioassay. Muscle mass was examined by dual-energy X-ray absorptiometry and physical performance was assessed by hand-grip strength, gait speed, step length and chair-stand test.ResultsAppendicular skeletal mass (ASM) was positively associated with total testosterone (TT;P<0.001), free testosterone (FT;P<0.001), and total E2(P<0.001) but not with free E2(P=0.102). After adjustment for age, serum SHBG and relative ASM, both TT and FT were significantly associated with grip strength, narrow-walk speed and the composite neuromuscular score. Higher total E2, but not free E2was associated with lower grip strength (P<0.05) after adjustment for age, FT, SHBG and relative ASM.ConclusionsTestosterone level was related to both muscle mass, strength and physical performance. Total E2level, though related to muscle mass positively, affected muscle strength adversely in older men.

Resistance Training Program

As aging continues to grow in our society, sarcopenia and associated fall risk is considered a public health problem since falling is the third cause of chronic disability. Falls are negatively related to functionality and independence and positively associated with morbidity and mortality. The cost of treatment of secondary injuries related to falls is high. For example, one in ten fall incidents leads to bone fractures and several other comorbidities. As demonstrated by several experimental studies, adopting a more active lifestyle is critical for reducing the number of fall episodes and their consequences. Therefore, it is essential to debate the proven physical exercise methods to reduce falls and fall-related effects. Since muscle mass, muscle strength, bone density, and cartilage function may play significant roles in daily activities, resistance training may positively and significantly affect the elderly. This narrative review aimed to examine current evidence on existing resistance training using resistance machines and bodyweight or low-cost equipment for the elderly and how they are related to falls and fall-related consequences. We provide theoretical links between aging, sarcopenia, and falls linking to resistance training and offer practical suggestions to exercise professionals seeking to promote regular physical exercise to promote quality of life in this population. Exercise programs focusing on strength may significantly influence muscle mass and muscle strength, minimizing functional decline and risk of falling. Resistance training programs should be customized to each elderly according to age, sex, and other fundamental and individual aspects. This narrative review provides evidence to support recommendations for practical resistance training in the elderly related to intensity and volume. A properly designed resistance training program with adequate instructions and technique is safe for the elderly. It should include an individualized approach based on existing equipment (i.e., body weight, resistance machines). Existing literature shows that exercise performance towards 2–3 sets of 1–2 exercises per major muscle group, performing 5–8 repetitions or achieving intensities of 50–80% of 1RM, 2–3 times per week should be recommended, followed by training principles such as periodization and progression. Bearing this in mind, health and exercise professionals should combine efforts focusing on efficient strategies to reduce falls among the elderly and promote higher experiences of well-being at advanced stages in life.

Abstract Background despite of the beneficial effects of fibroblast growth factor (FGF) 21 in several metabolic diseases, the association of plasma FGF21 with muscle mass and muscle strength is still unclear. Methods a total of 386 community-dwelling older adults aged 70–84 years were analysed. Appendicular skeletal muscle mass was measured using dual-energy X-ray absorptiometry and normalised to the square of height (ASM/ht2). Muscle strength was assessed using the hand grip strength (HGS) test. The definitions of low muscle mass (LMM) and low muscle strength (LMS) were based on the Asian Working Group for Sarcopenia. Results plasma FGF21 was significantly lower in participants with LMM than in those with normal muscle mass (289.7 [192.4–448.3] vs. 345.6 [238.6–503.2] pg/ml, P = 0.008). In contrast, the LMS group had a significantly higher plasma FGF21 level than the normal muscle strength group (369.7 [244.4–591.1] vs. 309.7 [205.3–444.8] pg/ml, P = 0.006). In the partial correlation analysis, following adjustment for age, sex and body mass index, FGF21 levels had no significant association with ASM/ht2, but were negatively associated with HGS (r = −0.112, P = 0.029). Furthermore, after multivariate adjustment for confounding variables, the odds ratio for the risk of LMS was 2.32 (95% confidence interval 1.20–4.46) when comparing the highest with the lowest FGF21 quartile. Conclusions circulating FGF21 levels are negatively associated with muscle strength but are not independently correlated with muscle mass.
