Background: Decreased muscle strength and limited physical performance are key elements of frailty and sarcopenia. The relative value of grip and knee extension strength for explaining walking performance has not been clearly established. Objectives: Compare the ability of grip and knee extension strength to explain gait speed. Design: Retrospective use of cross-sectionally obtained data. Setting: Patients’ homes. Participants:Forty-four ambulatory women patients at least 65 years of age. Measurements: Grip and knee extension forces obtained bilaterally with dynamometers and comfortable gait speed. Results: Knee extension forces were, but grip strength forces were not, correlated significantly with gait speed. Knee extension forces were able, but grip strength forces were not able, to satisfactorily identify patients with gait speeds < .40 m/sec. Conclusions:For women receiving therapy in a home-care setting, physical performance as reflected by gait speed is better explained by knee extension strength than by grip strength.

Grip strength and gait speed have both been recommended as “vital signs” for older adults. I,therefore, sought to determine the extent to which grip strength and comfortable gait speed were limited andrelated in a sample of older women home-care patients. A retrospective analysis was conducted using archivedinitial therapy records of 33 older women (mean age = 80.7 years) residing in their homes in New England(USA). Demographics, bilateral grip strength and usual gait speed data were extracted from the records. Best gripstrength was 80.1% of its reference norm. Usual gait speed was 38.4% of its reference norm. Significantly morepatients were below reference norm for gait speed. Both measures were significantly less than functionalstandards as well. The measures were not correlated significantly. Grip strength and gait speed are sensitive tolimitations in older women home-care patients, but not equally so.

Abstract Background: The increasing number of older adults with obesity is a growing public health problem because of increased risk of fractures especially at the ankle and upper leg despite normal or high bone mineral density. Among the contributory factors for fracture risk in this population may be aging- and obesity- associated physical frailty and impaired bone quality. However, how the adverse changes in physical function and body composition in this aging and obese population contribute to bone quality as assessed by finite element analyses (FEA) of bone strength has not been determined. Methods: One-hundred sixty-nine older (age ≥ 65 yrs.) adults with obesity (BMI ≥ 30 kg/m2) were recruited to participate in lifestyle intervention trials at our Medical Center. All underwent baseline measurements of bone strength (failure load [N] and stiffness [N.mm-1]) as estimated using FEA from high-resolution peripheral quantitative tomography (HR-pQCT) of the distal radius and tibia. In addition, body composition (appendicular lean mass/BMI [ALMBMI], fat mass/height2 [FMI]) was assessed by dual-energy x-ray absorptiometry (DXA) and physical function by the modified physical performance test (PPT), knee extension strength (isokinetic dynamometry), hand grip strength, and 4-meter gait speed. Results: Bivariate analyses showed that ALMBMI (r=.57 to .58), FMI (r=-.16 to -.17), gait speed (r=.20 to .21), grip strength (.56 to .57), and knee extension strength (r=.40 to .42) correlated with stiffness and failure load at the distal radius (all P&lt;0.05). In addition, ALMBMI (r=.65 to .67), FMI (r=-.22 to .23), gait speed (r+.18 to .19), grip strength (r=.58 to .59), and knee extension strength (r=.44 to .45) correlated with stiffness and failure load at the distal tibia (all P&lt;0.05). Controlling for age and sex, multiple regression analyses revealed that ALMBMI (β=.34 to .35) and grip strength (β=.28 to .29) were the independent predictors of stiffness and failure load at the distal radius, explaining 45% to 46% of the variance in stiffness and failure load (P&lt;0.001). On the other hand, multiple regression analyses revealed that ALMBMI (β=.45 to .52), grip strength (β=.27 to .28), and FMI (β=.17 to .18) were the independent predictors of stiffness and failure load at the distal tibia, explaining 74% to 75% of the variance in stiffness and failure load (P&lt;0.001). Conclusions: These findings suggest the importance of preserving muscle mass while reducing fat mass and improving physical function to maintain bone quality and decrease the risk of fractures when older adults with obesity undergo lifestyle intervention.

PURPOSE: Sarcopenia, also known as the age-related loss of muscle mass and muscle fitness, and physical performance, has been related to many adverse health outcomes. Resistance exercise may have an important role in effecting strategy for sarcopenia in aging populations. The purpose of this study is to systematically assess the effects resistance exercise interventions on muscle mass, muscle strength, and physical performance in elderly diagnosed with sarcopenia.METHODS: A comprehensive search on electronic databases, including PubMed, EMBASE, CINAHLPlus, SPORTDiscus, KERIS, KISS, and NAL were conducted. Eligible studies were divided into exercise and randomized controlled trials in elderly with sarcopenia. Searches retrieved 1,067 titles. Eighty full texts were evaluated, and seven studies were used for final systematic reviews. CMA (Comprehensive Meta-Analysis) ver 3.0 was used for meta-analysis.RESULTS: Meta-analysis showed that lower muscle mass (ES=0.579, 95% CI: 0.266-0.892, <i>p</i>=.000), appendicular muscle mass (ES=0.341, 95% CI: 0.006-0.676, <i>p</i>=.046), right hand grip strength (ES=0.739, 95% CI: 0.216-1.262, <i>p</i>=.006), left hand grip strength (ES=0.692, 95% CI: 0.167-1.217, <i>p</i>=.010), knee extension strength (ES=1.448, 95% CI: 0.273-2.624, <i>p</i>=.016), and timed up and go (ES=1.471, 95% CI: 0.492-2.450, <i>p</i>=.003) significantly improved in response to resistance exercise programs.CONCLUSIONS: Sarcopenia is increasing with the growing elderly population; thus prevention and effective interventions are very important. The data suggest that resistance exercise may be actual in enhancing not only appendicular muscle mass, but also knee extension strength and timed up and go in elderly diagnosed with sarcopenia. Further follow-up studies on larger populations and a variety of approaches are required to reconfirm these results.

BACKGROUND AND OBJECTIVE: Numerous studies have addressed the relationship between paretic knee extension strength and comfortable walking speed after stroke. However, the correlations reported are highly variable. This review sought to summarize the correlational data using meta-analysis. METHODS: Relevant literature was identified via a search of 3 bibliographic databases. Articles were screened and perused for inclusion. Included articles were examined for information on the sample studied, procedures for measuring strength and gait speed, and correlations reported between the 2 variables. Meta-analysis was used to calculate a summary correlation. RESULTS: Of 299 unique articles, 18 met inclusion criteria. Articles were diverse in regard to samples studied, procedures described, and correlations reported. Meta-analysis using data from all included studies revealed a summary correlation of 0.51. For studies using hand-held or isokinetic dynamometry, the summary correlation was 0.46 and 0.59 respectively. CONCLUSIONS: This study provides a better indication of the correlation between paretic knee extension strength and comfortable gait speed than individual studies. The correlation is high enough to provide support for the routine measurement of paretic knee extension force for individuals who have experienced a stroke.

Abstract Background Physical activity (PA) is important to maintaining functional independence. It is not clear how patterns of change in late-life PA are associated with contemporaneous changes in physical performance measures. Methods Self-reported PA, gait speed, grip strength, timed chair stand, and leg power were assessed in 3,865 men aged ≥ 65 years at baseline (2000–2002) and Year 7 (2007–2009). Group-based trajectory modeling, using up to four PA measures over this period, identified PA trajectories. Multivariate linear regression models (adjusted least square mean [95% confidence interval {CI}]) described associations between-PA trajectories and concurrent changes in performance. Results Three discrete PA patterns were identified, all with declining PA. Linear declines in each performance measure (baseline to Year 7) were observed across all three PA groups, but there was some variability in the rate of decline. Multivariate models assessing the graded response by PA trajectory showed a trend where the high-activity group had the smallest declines in performance while the low-activity group had the largest (p-for trend &lt; .03). Changes in the high-activity group were the following: gait speed (−0.10 m/s [−0.12, −0.08]), grip strength (−3.79 kg [−4.35, −3.23]), and chair stands (−0.38 [−0.50, −0.25]), whereas changes in the low-activity group were the following: gait speed (−0.16 [−0.17, −0.14]), grip strength (−4.83 kg [−5.10, −4.55]), and chair stands (−0.53 [−0.59, −0.46]). Between-group differences in leg power trajectories across PA patterns were not significant. Conclusions Declines in functional performance were higher among those with lower PA trajectories, providing further evidence for the interrelationship between changes in PA and performance during old age.

Background: At present, it is unclear whether older, obese persons with or without sarcopenia respond differently to training. Furthermore, there are no differentiated recommendations for resistance training for this special target group. Objectives: The objectives are to investigate the changes in the physical parameters of older, obese men caused by training and to reappraise the modalities of resistance training for older persons. Design: Pre-test-post-test design. Participants: The participants were 33 physically inactive and obese older men (≥ 65 years, BMI ≥ 30 kg/m2), with-out severe diseases. Subjects were divided into two groups: NSAR (no or presarcopenia, n= 15) or SAR (sarcopenia, n= 18). Intervention: The intervention consisted of progressive resistance training, twice a week for 16 weeks with finally 80-85% of maximum strength and three sets with 8-12 repetitions. The training contained six exercises for the major muscle groups. Measurements: Sarcopenia was assessed using the Short Physical Performance Battery (SPPB), hand-grip strength, skeletal muscle mass index (SMI), and gait speed over a 6-meter walkway. Furthermore, the maximum dynamic strength (1 RM) was assessed. Results: At baseline, the NSAR group had significantly better values in SMI, SPPB score, hand-grip strength, and 1 RM. After training, the results in both groups displayed an increase in 1 RM at the lower limbs (NSAR 18%, SAR 38%) and the upper limbs (NSAR 12%, SAR 14%). Also, the SPPB score (NSAR 11%, SAR 15%) and the 6-m-gait speed (NSAR 5%, SAR 10%) increased. The SAR group was able to increase their right hand-grip strength by 12%, whereas the NSAR group maintained their initial high strength values. SMI did not change in both groups. Conclusions: Both groups show improvements after resistance training with slightly more benefits for men with sarcopenia. Results of this study can be used to define specific training regimens for N(SAR) subjects.

Abstract Background A claims-based frailty index (CFI) was developed based on a deficit-accumulation approach using self-reported health information. This study aimed to independently validate the CFI against physical performance and adverse health outcomes. Methods This retrospective cohort study included 3,642 community-dwelling older adults who had at least 1 health care encounter in the year prior to assessments of physical performance in the 2008 Health and Retirement Study wave. A CFI was estimated from Medicare claims data in the past year. Gait speed, grip strength, and the 2-year risk of death, institutionalization, disability, hospitalization, and prolonged (>30 days) skilled nursing facility (SNF) stay were evaluated for CFI categories (robust: <0.15, prefrail: 0.15–0.24, mildly frail: 0.25–0.34, moderate-to-severely frail: ≥0.35). Results The prevalence of robust, prefrail, mildly frail, and moderate-to-severely frail state was 52.7%, 38.0%, 7.1%, and 2.2%, respectively. Individuals with higher CFI had lower mean gait speed (moderate-to-severely frail vs robust: 0.39 vs 0.78 m/s) and weaker grip strength (19.8 vs 28.5 kg). Higher CFI was associated with death (moderate-to-severely frail vs robust: 46% vs 7%), institutionalization (21% vs 5%), activity of daily living disability (33% vs 9%), instrumental activity of daily living disability (100% vs 22%), hospitalization (79% vs 23%), and prolonged SNF stay (17% vs 2%). The odds ratios per 1-SD (=0.07) difference in CFI were 1.46–2.06 for these outcomes, which remained statistically significant after adjustment for age, sex, and a comorbidity index. Conclusion The CFI is useful to identify individuals with poor physical function and at greater risks of adverse health outcomes in Medicare data.

The optimal management of sarcopenia requires appropriate endpoint measures to determine intervention efficacy. While hand grip strength is a predictor of morbidity and mortality, lower extremity strength may be better associated with functional activities in comparison to hand grip strength. The purpose of our study was to examine the comparative association of upper and lower extremity strength with common measures of physical performance in older adults. Thirty community-dwelling men, aged 62.5 ± 9.2 years, completed body composition analysis, quantitative strength testing, and performance-based tests of functional status. Hand grip force values were not significantly associated with knee extensor or flexor torque values (p > 0.05). Hand grip force was only associated with fast gait speed, while knee extensor torque at 60°/s was the only variable significantly associated across all functional outcome measures: customary gait speed, fast gait speed, sit to stand time, and the Physical Performance Test (p < 0.02). Hand grip strength was not a proxy measure of lower extremity strength as assessed in this study. Overall, lower extremity muscle strength values had the strongest associations with participant functional performance. Lower extremity strength testing may provide additional value as an endpoint measure in the assessment and clinical management of sarcopenia.
