Abstract Background and aims Walking is the core physical activity of older persons. The assessment of walking capacity is increasingly important for clinical purposes and clinical research. Differences between assessment tools and protocols for short walks to obtain gait characteristics can be responsible for changes, e.g., in gait speed from 0.1 to 0.2 m/s. The purpose of this study was to generate further knowledge for the harmonization and/or standardization of short walk-test protocols for assessing gait characteristics under supervised conditions. Methods For this cross-sectional study, 150 community-dwelling older adults (mean age 80.5 ± 4.5 years) were recruited. Participants performed eight walks differing in the distance (8-versus 4-m), static versus dynamic trials and comparing different test speed instructions (usual versus maximal) on an electronic walkway. Results A meaningful significant difference in mean usual gait speed was documented comparing the 4-m dynamic and static test protocol (0.12 m/s; p = 0.001). For the same comparison over an 8-m distance (dynamic versus static) and for the comparison between usual gait speed over 4-and 8-m, the differences in gait speed were smaller, but still statistically significant (p = 0.001). Conclusions Gait speed was faster, if the test protocol did not include a static start or stop. The differences were greater for a shorter walking distance. This aspect should be considered for the comparison of study results and is particularly relevant for systematic reviews and meta-analyses.

<b><i>Background:</i></b> Circulating osteoprogenitor (COP) cells are a surrogate of the bone marrow mesenchymal stem cells with high levels observed in osteoporosis and the initial stages of fracture healing. Conversely, a low percentage of COP cells (%COP) is strongly associated with frailty and disability. However, it is unknown whether %COP is associated with sarcopenia, a musculoskeletal disease closely related to frailty. <b><i>Objectives:</i></b> This study sought to determine the associations between %COP and sarcopenia defined using the Sarcopenia Definitions and Outcomes Consortium (SDOC) criteria. <b><i>Methods:</i></b> Data from a random sample of 73 community-dwelling older persons enrolled in the Nepean Osteoporosis and Frailty study (median age 74 years; 60% female) were analyzed. %COP was quantified by flow cytometry using selective gating of CD45/osteocalcin (OCN) + cells. Sarcopenia was defined using handgrip strength and gait speed with cut points as per the SDOC criteria. Linear regression was used for analysis. <b><i>Results:</i></b> Sarcopenia was identified in 19% of participants, all of whom were frail. After adjusting for age, sex, and interleukin 6, sarcopenic participants had 36% lower %COP (95% confidence interval [CI] −56%, −6%, <i>p =</i> 0.024). Both grip strength and gait speed showed associations with %COP (<i>p =</i> 0.065 and 0.002, respectively); however, after adjusting for age and frailty, only gait speed remained associated with %COP (0.1 m/s increase in gait velocity was associated with a 5% increase in %COP cells (95% CI 0%, 10%, <i>p =</i> 0.052). <b><i>Conclusions:</i></b> High levels of %COP are associated with better muscle function. Future longitudinal studies are required to elucidate the clinical utility of %COP as a potential biomarker or disease stratifier for sarcopenia.

Abstract Background Elderly adults undergoing hemodialysis (HD) have multiple comorbidities, physical frailty, and functional dependence with activities of daily living (ADL). ADL difficulty is an early predictor of ADL dependency in community-dwelling elderly adults. However, the characteristics of ADL difficulty in patients undergoing HD have not yet been reported. The present study aimed to examine the current status and characteristics of physical function and ADL difficulty in ambulatory elderly patients undergoing HD. Methods In all, 136 elderly outpatients undergoing HD and 40 community-dwelling controls participated in the present study. The characteristics, physical function (SARC-F score, grip strength, five-times sit-to-stand test time, usual gait speed, maximum gait speed, and short physical performance battery score), and scores from the ADL difficulty questionnaires [difficulty related to upper limb (U/L) and lower limb (L/L) functions] were compared between the HD and control groups. Multiple regression analysis was performed to examine whether the characteristics of physical function were able to discriminate ADL difficulty in the HD group. Results The HD group had a significantly greater SARC-F score, lower grip strength, longer five-times sit-to-stand test time, slower usual gait speed, slower maximum gait speed, lower short physical performance battery score, and lower U/L and L/L ADL difficulty scores compared to the control group (all P < 0.001). The distribution of U/L and L/L ADL difficulty scores showed a wider variation in the HD group than in the control group. The U/L ADL difficulty score was independently associated with the SARC-F score (β = −0.52, P < 0.001) and grip strength (β = 0.21, P = 0.02). The L/L ADL difficulty score was independently associated with the SARC-F score (β = −0.56, P < 0.001) and usual gait speed (β = 0.35, P < 0.001). Conclusions The elderly HD group had a poorer physical function and experienced stronger ADL difficulty than the control group. There was an association between ADL difficulty and sarcopenia or poor physical function among patients undergoing HD. These findings provide useful data for effective clinical management to prevent decline of ADL in ambulatory elderly patients undergoing HD.

Leg Extension Power

Abstract This study aimed to assess the validity and functional relevance of a standardized procedure to assess lower limb muscle power by means of the 30-s sit-to-stand (STS) test when compared to leg extension power (LEP), traditional STS performance and handgrip strength. A total of 628 community-dwelling older subjects (60–93 years) from the Copenhagen Sarcopenia Study were included. Physical performance was assessed by the 30-s STS and 10-m maximal gait speed tests. Handgrip strength and LEP were recorded by a hand-held dynamometer and the Nottingham power rig, respectively. STS muscle power was calculated using the subjects’ body mass and height, chair height and the number of repetitions completed in the 30-s STS test. We found a small albeit significant difference between LEP and unilateral STS power in older men (245.5 ± 88.8 vs. 223.4 ± 81.4 W; ES = 0.26; p < 0.05), but not in older women (135.9 ± 51.9 vs. 138.5 ± 49.6 W; ES = 0.05; p > 0.05). Notably, a large positive correlation was observed between both measures (r = 0.75; p < 0.001). Relative STS power was more strongly related with maximal gait speed than handgrip strength, repetition-based STS performance and relative LEP after adjusting for age (r = 0.53 vs 0.35–0.45; p < 0.05). In conclusion, STS power obtained from the 30-s STS test appeared to provide a valid measure of bilateral lower limb power and was more strongly related with physical performance than maximal handgrip strength, repetition-based STS performance and LEP.

Objective: The aim of this study is to investigate the effects of combined physical and cognitive training on fall rate and risks of falling in older adults with mild cognitive impairment. Design: The design of this study was an assessor-blinded, randomized controlled trial. Setting: The setting for this study is the community from Manila, Philippines. Subjects: In total, 92 community-dwelling older persons with mild cognitive impairment (aged 60–83) were randomly allocated to three intervention groups and one waitlist control group. Interventions: The physical training, cognitive training, and combined physical and cognitive training intervention programs were delivered for 60 to 90 minutes, one to three times per week for 12 weeks with six-month follow-up. Main measures: Participants were assessed at baseline, 12 weeks after baseline, and 36 weeks after baseline for fall incidence, overall fall risk, dynamic balance, walking speed, and lower limb strength. Results: No significant difference was observed across time and groups on fall incidence rate at 12 weeks ( P = 0.152) and at 36 weeks ( P = 0.954). The groups did not statistically differ in other measures except for a significant improvement in dynamic balance based on Timed Up and Go Test in the combined physical and cognitive training group (9.0 seconds with P = 0.001) and in the cognitive training alone group (8.6 seconds with P = 0.012) compared to waitlist group (11.1 seconds) at 36 weeks. Conclusion: There was no significant difference among groups on fall rate and risks of falling post-intervention. Dynamic balance was improved with combined physical and cognitive training and cognitive training alone. Further research with a larger sample size is needed to establish whether or not the interventions are effective.

Abstract Background Muscle and bone interactions might be associated with osteoporosis and sarcopenia. Urinary pentosidine and serum 25-hydroxyvitamin D (25(OH)D) might affect muscle and bone interactions. It is unclear whether these biomarkers are affected by age and sex or play a role in muscle and physical functions. We aimed to investigate the association between urinary pentosidine and serum 25(OH)D levels with muscle mass, muscle strength, and physical performance in community-dwelling adults. Methods Two-hundred and fifty-four middle-aged and elderly adults were enrolled. There was no significant difference in age between 97 men (75.0 ± 8.9 years) and 157 women (73.6 ± 8.1 years). The skeletal muscle mass index (SMI), grip strength, and gait speed were assessed. The urinary pentosidine level was measured. We evaluated the association of urinary pentosidine and serum 25(OH)D levels with age and sex (student’s t-test) and correlations between biomarker and each variable (Pearson’s correlation coefficients). Multiple regression analysis was performed with grip strength and gait speed as dependent variables and with age, height, weight, body mass index (BMI), speed of sound (SOS), SMI, glycated hemoglobin (HbA1c), estimated glomerular filtration rate (eGFR), 25(OH)D, and pentosidine as independent variables using the stepwise method. Results The urinary pentosidine level was negatively correlated with grip strength, gait speed, eGFR, and insulin-like growth factor-1 (IGF-1) in men and with SOS, grip strength, and gait speed in women. The serum 25(OH)D level was positively correlated with IGF-1 in women and grip strength in men. Grip strength was associated with age, height, and pentosidine in men and height and pentosidine in women. Gait speed was associated with age, BMI, and pentosidine in men and age, height, and pentosidine in women. Conclusion Urinary pentosidine levels are significantly associated with grip strength and gait speed and may serve as a biomarker of muscle and bone interactions.

Abstract Aim The decline of health and functional status as a result of old age makes it necessary to assess the Quality of Life (QoL) among older persons. There is, however, limited information in this regard from low and middle-income countries such as Nigeria. This study compares the QoL and associated factors among rural and urban community-dwelling older persons (≥ 60 years) in Oyo State, Nigeria. Subject and methods A cross-sectional, comparative community-based study was carried out using an interviewer-administered, semi-structured questionnaire. The QoL was determined using the World Health Organisation Quality of Life Brief Scale (WHOQOL-BREF). Data were analysed using Stata version 14 at p < 0.05. Results Overall, 1,180 (588 urban and 592 rural-dwelling) respondents were interviewed. Females constituted more than half of the respondents in both communities, accounting for over two thirds (69.2%) of the population. The mean QoL scores were similar in the psychological (54.2 ± 7.4) and environmental (54.7 ± 9.5) domains. However, the mean score for the physical domain was 69.2 ± 17.0 and 74.1 ± 12 for the social domain. There was no statistically significant difference between mean scores of the QoL in the two locations except in the environmental domain (p < 0.05). Good self-rated health was a common positive predictor of higher mean scores across the four domains in both the rural and urban settings (p < 0.05). Conclusion The rural–urban differences in the mean quality of life scores in the environmental domain in the study and poorer scores in the psychological and environmental domains necessitate areas for targeted intervention and more in-depth research.

Active participation in exercise may help to improve physical and psychological functions for older people. Regretfully, most of them do not engage in long term exercise due to several barriers. This puts them at high risk of may chronic illness that will limit their activities of daily living. The aim of this study is to determine the effectiveness of the behavioral and exercise program on cardio respiratory fitness among 63 community-dwelling olders. At the end of six months, there is a significant difference for cardio respiratory fitness and exercise engagement. Thus, improved their overall quality of life.

Objectives. This study aimed to describe the cross-sectional and longitudinal association between alcohol intake and gait parameters in older persons.Methods. Community-dwelling persons aged 65–70 years (N=807). Information on health, functional status, and alcohol use was self-reported at baseline and at 3-year follow-up, whereas gait speed and stride-to-stride variability were measured while walking only (single task) and under dual tasking (counting backwards).Results. Compared to light-to-moderate drinking, heavy drinking was associated with slower gait speed in single task (adj. coeff.: −.040, 95% CI: −.0.78 to −.002,p=.035). No significant association was observed between heavy drinking and gait speed variability. Nondrinkers walked significantly slower than light-to-moderate drinkers in dual task and had significantly higher gait speed variability in both single and dual task, but these associations disappeared after adjustment for comorbidity. At follow-up, 35.2% and 34.1% of the participants walked significantly slower in single and dual task, respectively. This proportion varied a little across drinking categories.Conclusion. At baseline, heavy alcohol consumption was significantly associated with slower gait speed in single task. Selective survival of the fittest heavy drinkers probably explains why this association faded in longitudinal analyses. The trend of poorer gait performance in nondrinkers disappeared after adjustment for comorbidity, suggesting confounding by a worse health status.
