Abstract As slow gait speed is a major feature of frailty and a diagnostic criterion of sarcopenia, gait speed measurement is widely used. Nowadays, with development of wearable devices, it is possible to measure daily-life gait speed without additional effort just by wearing the device. It is meaningful to measure daily-life gait speed and to analyze the association between the speed and sarcopenia. Participants were men over 50 years of age who visited the university hospital. Daily-life gait speed was checked using a smart belt (WELT) for 4 weeks. Afterwards, a survey about past medical history, usual gait speed measurement, handgrip strength measurement, and dual energy X-ray absorptiometry were performed. A total of 217,548 daily-life gait speed measurement data were analyzed for 106 participants. The mean daily-life gait speed was 1.23 ± 0.26 m/s. The mean age was 71.1 ± 7.6, and daily-life gait speed was significantly slower as people get older. (P<0.001) Additionally, weekday gait speed (1.23 ± 0.26 m/s) was significantly faster than weekend gait speed (1.22 ± 0.26 m/s). (P<0.001) Participants with sarcopenia (1.15 ± 0.25 m/s) had significantly slower mean daily-life gait speed than normal subjects (1.23 ± 0.26 m/s). (P<0.001) In analyzing factors related to gait speed, age and skeletal muscle mass of lower limbs were significantly associated with mean daily-life gait speed. Additional information about the gait speed can be obtained by measuring daily-life gait speed, and the daily-life gait speed has a significant association with the skeletal muscle mass of lower limbs.

Speed Measurement

UNSTRUCTURED Gait speed measurement is used widely as a slow gait is a major feature of frailty and a diagnostic criterion for sarcopenia. With the development of wearable devices, it is possible to obtain daily life gait speed simply by wearing the device. Therefore, it is feasible and worthwhile to accurately determine the characteristics of daily-life gait speed and analyze their association with sarcopenia. We invited community-dwelling men over 50 years of age who had visited outpatient clinic at a tertiary university hospital. Daily life gait speed was assessed using a smart belt (WELT) the participants wore for a period of 4 weeks. Data from participants who wore the smart belt for at least 10 days during this period were included. After 4 weeks, data from a survey about medical and social history, “usual gait speed” measurements, handgrip strength measurements, and dual energy X-ray absorptiometry were analyzed. A total of 217,578 daily life gait speed data from 106 participants (mean age, 71.1 ± 7.6 years) were analyzed. The mean daily life gait speed was 1.23 ± 0.26 m/s. The daily life gait speed of the participants varied by time and day of the week. Daily life gait speed was significantly lower in older individuals (P<0.001). Participants with sarcopenia (1.12 ± 0.11 m/s) had significantly lower mean daily life gait speed than participants who did not have sarcopenia (1.23 ± 0.08 m/s; P<0.001). Analysis of factors related to mean daily life gait speed showed that age and skeletal muscle mass of the lower limbs were significantly associated characteristics. In conclusion, more diverse and accurate information about gait speed can be obtained by measuring daily life gait speed using a wearable device over an appropriate time period, compared to one-time measurements performed in a laboratory setting. Importantly, daily life gait speed is significantly associated with skeletal muscle mass of the lower limbs, in addition to age.

Abstract Background The accumulation of advanced glycation end product (AGE) might exert deleterious effects on musculoskeletal properties. Our study aims to clarify this possible association in a large general population. Methods This study investigated a general population of 9,203 patients (mean age, 57.8 years). Skeletal muscle mass was measured by bioelectrical impedance analysis, whereas accumulation of AGEs was assessed by skin autofluorescence (SAF-AGE). The muscle strength of upper and lower limbs and usual gait speed were measured in a portion of older (≥60 years of age) participants (n = 1,934). The speed of sound (SOS) in the calcaneal bone was assessed via a quantitative ultrasound technique. Results In the total population, the frequency of low skeletal muscle mass linearly increased with the SAF-AGE quartiles (Q1: 14.2%, Q2: 16.1%, Q3: 21.1%, Q4: 24.8%; p < .001), and this association was independent of covariates including glycemic traits (Q4: odds ratio [OR] = 1.48, p < .001). The association between the highest SAF-AGE quartile and low skeletal muscle mass remained significant in the older subpopulation (OR = 1.85, p = .002). A similar but weak association was observed for low SOS (Q1: 8.9%, Q2: 8.3%, Q3: 10.4%, Q4: 12.2%; p < .001). Similar inverse associations were also observed with grip strength (OR = 1.98, p = .003), hip flexion strength (OR = 1.50, p = .012), and hip abduction strength (OR = 1.78, p = .001), but not with usual gait speed. Conclusion Accumulation of AGEs might be a deleterious factor for musculoskeletal properties.

Abstract Purpose : Although a change in skeletal muscle mass index (SMI) 4 months after esophagectomy impacts prognosis, predictors of a change in SMI have not been revealed. The purpose of this exploratory retrospective study was to clarify the predictors of a change in SMI after curative esophagectomy in elderly patients with esophageal cancer.Methods : Fifty-four patients who underwent esophagectomy and perioperative rehabilitation from 2015 to 2018 were enrolled. Preoperative and postoperative SMI (cm 2 /m 2 ) were calculated using computed tomography images. The ratio change in SMI was calculated as follows: (postoperative SMI − preoperative SMI) ÷ preoperative SMI × 100%. Potential predictors of a change in SMI ratio were analyzed by multiple regression. Results : The mean ratio change in SMI 4 months after esophagectomy was −7.1% ± 9.4%. The ratio change in quadriceps muscle strength in the first month after surgery ([postoperative strength − preoperative strength] ÷ preoperative strength × 100%) (standardized β = .273, p = .038) and neoadjuvant chemotherapy (NAC) (standardized β = .398, p = .006) were predictors of the ratio change in SMI independent of age, sex, pathological stage, and preoperative SMI. Conclusion : Quadriceps muscle weakness in the first month after esophagectomy and NAC were predictors of the ratio change in SMI after esophagectomy. Continuous postoperative comprehensive rehabilitation and supportive care may inhibit loss of skeletal muscle mass.

Objectives: To investigate the relationship between leg skeletal muscle mass asymmetry and usual gait speed in older adults. Methods: The subjects were 139 community-dwelling older adults. The asymmetry index was calculated using the leg skeletal muscle mass index (LSMI) values of both legs. The subjects were divided into “large” and “small” asymmetry groups based on the asymmetry index. The relationship between asymmetry and gait speed was analyzed using a linear regression model. The appendicular skeletal muscle mass index and LSMI were included as adjustment variables in the analysis. Results: The asymmetry index and having a “large” asymmetry were independently related to gait speed, even after adjusting for covariates such as appendicular skeletal muscle mass index and LSMI. Discussion: Leg skeletal muscle mass asymmetry was related to gait speed independently of the appendicular skeletal muscle mass index and LSMI values. A skeletal muscle mass evaluation among older adults should include an assessment of the total skeletal muscle mass and its asymmetry.

Elderly women exhibit a high risk of type 2 diabetes (T2D), but no definitive data exist about the possible role of postmenopausal increases in visceral adiposity, the loss of lean body mass, or decreases in the sum of the lean mass of arms and legs (appendicular skeletal muscle mass (ASMM)). This retrospective, longitudinal study investigated whether body composition (bioelectrical impedance analysis) predicted the development of impaired fasting glucose (IFG) or T2D in a cohort of 159 elderly women (age: 71 ± 5 years, follow-up: 94 months) from southern Italy (Clinical Nutrition and Geriatric Units of the “Mater Domini” University Hospital in Catanzaro, Calabria region, and the “P. Giaccone ”University Hospital in Palermo, Sicily region). Sarcopenia was defined in a subgroup of 128 women according to the EWGSOP criteria as the presence of low muscle strength (handgrip strength <16 kg) plus low muscle mass (reported as appendicular skeletal muscle mass <15 kg). Participants with a low ASMM had a higher IFG/T2D incidence than those with a normal ASMM (17% vs. 6%, p-adjusted = 0.044); this finding was independent of BMI, fat mass, waist circumference, and habitual fat intake (OR = 3.81, p = 0.034). A higher incidence of IFG/T2D was observed in the subgroup with sarcopenia than those without sarcopenia (33% vs. 7%, p-adjusted = 0.005) independent of BMI and fat mass (OR = 6.75, p = 0.007). In conclusion, this study demonstrates that elderly women with low ASMM had a higher probability of developing IFG/T2D. Further studies are needed to confirm these results in men and in other age groups.

Sarcopenia is prevalent in postmenopausal women but is inconclusive in total thyroidectomy and under levothyroxine replacement. We aim to analyze the determinants of sarcopenia and investigate the early detection of sarcopenia in this group. Fifty postmenopausal women with total thyroidectomy were measured for body composition via Dual-energy X-ray Absorptiometry (DXA) and Appendicular Skeletal Muscle mass divided by the height square (ASM/ht2). Handgrip strength and gait speed and Geriatric Nutritional Risk Index (GNRI) were calculated. Eight determinants associated with sarcopenia include GNRI (β, 0.042; 95% confidence interval (CI), 0.021 to 0.064), femoral neck BMD (β, 0.989; 95% CI, 0.049 to 1.929), TSH (β, 0.192; 95% CI, 0.027 to 0.357), and thyroglobulin Ab (0.657; 95% CI, 0.210 to 1.103) for ASM/height2; menopausal years (β, −3.112; 95% CI, −5.661 to −0.563) and ASM/height2 (β, 2.669; 95% CI, 1.073 to 4.265) for handgrip strength; and GNRI (β, 0.062; 95% CI, 0.019 to 0.105), T3 (β, −3.541; 95% CI, −7.019 to −0.063), and age (β, 0.043; 95% CI, 0.003 to 0.084) for gait speed. Our study confirmed a high prevalence of low skeletal muscle mass index in postmenopausal women with total thyroidectomy and revealed a number of determinants that could help early diagnosis and management this disease in daily clinical practice.

AbstractSarcopenia is an age-related disease with an increased risk of mortality. It is emerging that low serum 25-hydroxyvitamin D [25(OH)D] affects the sarcopenic state in general, but in rheumatoid arthritis (RA), these associations are not understood although the prevalence of vitamin D insufficiency is high in RA. We conducted a cross-sectional study of older female outpatients from our cohort (KURAMA) database. We measured skeletal muscle mass, handgrip strength, and gait-speed to diagnose severe sarcopenia. The serum 25(OH)D concentration was measured using electrochemiluminescence immunoassay. A total of 156 female patients with RA (sarcopenia:44.9%, severe sarcopenia: 29.5%, and without sarcopenia: 25.6%) were enrolled. Classification of vitamin D status at a cutoff point of median 25(OH)D concentration revealed that low 25(OH)D status was associated with a high prevalence of severe sarcopenia and with low measured values of muscle mass, handgrip, and gait speed. Furthermore, multivariable logistic regression analysis identified that low 25(OH)D status was associated with a high prevalence of severe sarcopenia (OR 6.00; 95% CI 1.99–18.08).The same association was observed when the cut-off value was set at 20 ng/ml. In components of sarcopenia, both low physical performance and muscle mass were associated with low 25(OH)D status. In conclusion, vitamin D status was inversely associated with severe sarcopenia, low physical performance, and low skeletal muscle mass. Modification of vitamin D status including vitamin D supplementation should be investigated as a therapeutic strategy for sarcopenic patients with RA.

Volleyball is an exceedingly popular physical activity in the adolescent population, especially with females. The study objective was to assess the effect of volleyball training and natural ontogenetic development on the somatic parameters of adolescent girls. The study was implemented in a group of 130 female volleyball players (aged 12.3 ± 0.5 – 18.1 ± 0.6 years) along with 283 females from the general population (aged 12.3 ± 0.5 – 18.2 ± 0.5 years). The measured parameters included: body height (cm), body mass (kg), body fat (kg, %), visceral fat (cm2), body water (l), fat free mass (kg) and skeletal muscle mass (kg, %). Starting at the age of 13, the volleyball players had significantly lower body fat ratio and visceral fat values than those in the general population (p < 0.001 in body fat % and p < 0.01 in visceral fat). In volleyball players, the mean body fat (%) values were 17.7 ± 6.6 in 12-year-old players, 16.7 ± 4.9 in 13-year-old players, 18.5 ± 3.9 in 16-year-old players, and 19.3 ± 3.1 in 18-year-old players. In the general population, the mean body fat (%) values were 19.6 ± 6.3 in 12-year-old girls, 21.7 ± 6.4 in 13-year-old girls, 23.4 ± 6.1 in 16-year-old girls, and 25.8 ± 7.0 in 18-year-old girls. The visceral fat (cm2) mean values were 36.4 ± 19.3 in 12-year-old players, 39.2 ± 16.3 in 13-year-old players, 45.7 ± 14.7 in 16-year-old players, and 47.2 ± 12.4 in 18-year-old players. In the general population, the mean visceral fat (cm2) values were 41.4 ± 21.1 in 12-year-old girls, 48.4 ± 21.5 in 13-year-old girls, 58.0 ± 24.7 in 16-year-old girls, and 69.1 ± 43.7 in 18-year-old girls. In volleyball players, lower body fat ratio corresponded with a higher skeletal muscle mass ratio. The differences found in skeletal muscle mass ratio were also significant starting at the age of 13 (p < 0.001). The mean skeletal muscle mass (%) values were 44.1 ± 3.4 in 12-year-old volleyball players, 45.4 ± 2.5 in 13-year-old players, 45.0 ± 2.2 in 16-year-old players, and 44.7 ± 1.8 in 18-year-old players. In the general population, the mean skeletal muscle mass (%) values were 42.8 ± 3.2 in 12-year-old girls, 42. ± 4.1 in 13-year-old girls, 41.9 ± 3.3 in 16-year-old girls, and 40.6 ± 3.7 in 18-year-old girls. Differences in body composition between the individual age groups were similar between the volleyball players and girls in the general population. The results indicate that regular volleyball training influences the body composition of young females however the development of body composition parameters is subject to their ontogenetic development.
