Vibration Therapy

Abstract Background Sarcopenia, a progressive loss of muscle mass and function with advancing age, is a prevalent condition among older adults. As most older people are too frail to do intensive exercise and vibration therapy has low risk and ease of participation, it may be more readily accepted by elderly individuals. However, it remains unclear whether vibration therapy would be effective among older adults with sarcopenia. This systematic review and meta-analysis examined the effect of vibration therapy including local vibration therapy and whole-body vibration therapy, for enhancing muscle mass, muscle strength and physical function in older people with sarcopenia. Methods A systematic literature search was conducted in March 2019 in the following 5 electronic databases: PubMed, CINAHL, Embase, PEDro, and the Cochrane Central Register of Controlled Trials, with no restriction of language or the year of publication. Randomized controlled trials and quasi-experimental studies examining effects of vibration therapy on muscle mass, muscle strength or physical function in older adults with sarcopenia were included in this systematic review. Two reviewers independently assessed the methodological quality of the selected studies. Results Of the 1972 identified studies, seven publications from six studies involving 223 participants were included in this systematic review. Five of them conducted whole-body vibration therapy, while two conducted local vibration therapy. A meta-analysis of randomized controlled studies indicated that muscle strength significantly increased after whole-body vibration therapy (SMD 0.69, 95% CI 0.28 to 1.11, I2 = 0%, P = 0.001) and local vibration therapy (SMD 3.78, 95% CI 2.29 to 5.28, P < 0.001). Physical performance measured by the sit-to-stand test and the timed-up-and-go test were significantly improved after the intervention (SMD -0.79, 95% CI − 1.21 to − 0.37, I2 = 0%, P < 0.001) and SMD -0.83, 95% CI − 1.56 to − 0.11, I2 = 64%, P = 0.02, respectively). Conclusion Vibration therapy could be a prospective strategy for improving muscle strength and physical performance in older adults with sarcopenia. However, due to the limited number of the included studies, caution is needed when interpreting these results. More well-designed, large sample size studies should be conducted to further explore and validate the benefits of vibration therapy for this population.

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.

Objective: To conduct a systematic review and meta-analyses to assess the efficacy of physical exercise on strength, muscle mass and physical function in adult patients with non-alcoholic fatty liver disease (NAFLD). Design: We conducted a systematic review and meta-analysis of seven studies to investigate the effect of exercise training interventions in muscle strength, muscle mass and physical performance. Data sources: We identified relevant randomised controlled trials (RCT) in electronic databases (PubMed, CINAHL and Scopus). Eligibility criteria: We selected seven RCTs from 66 screened studies. The inclusion criteria were peer-reviewed and English writing articles that included adult patients with liver disease of non-alcoholic origin, applied resistance training, endurance training or both, and assayed at least one variable of sarcopenia. Results: Physical performance criterion improved in the exercise groups (mean differences [MD] 8.26 mL/Kg*min [95% CI 5.27 to 11.24 mL/Kg*min], p < 0.0001) versus the control groups; muscle mass, determined as lean body mass (LBM), showed no evidence of the beneficial effects of exercise versus the control groups (MD 1.01 Kg [95% CI -1.78 to 3.80 Kg], p = 0.48); we did not include muscle strength, as none of the selected studies evaluated it. Summary/conclusion: Exercise training is a useful intervention strategy to treat sarcopenia in patients with NAFLD; it increases their physical performance in the form of aerobic capacity but does not affect LBM. Future research should include muscle strength assessments and resistance training to evaluate the effects of exercise training on sarcopenia in NAFLD patients.

Muscle Fitness

Background: Lack of exercise is a prevalent problem in patients receiving dialysis. Although guidelines recommend these patients to undertake suitable exercise, no exercise type or intensity has been suggested, and the effect of exercise on muscle fitness in dialysis patients is not clear. This study investigated the effect of exercise on muscle fitness, including muscle mass, muscle strength, and physical performance, in patients on dialysis. Methods: A systematic review and a meta-analysis of randomized controlled trials (RCTs) were conducted. Five English and 4 Chinese databases were searched from their inception to July 2018. Two independent reviewers searched the different databases, selected trials, conducted bias assessment, and extracted the data. Results: A total of 21 RCTs meeting the inclusion criteria were included in this review. Pooled results demonstrated that resistance training significantly improved leg mass (standard mean difference [SMD] 0.34, 95% CI [0.06–0.62], p= 0.02) whereas aerobic training did not (SMD 0.87, 95% CI [–0.11 to 1.86], p = 0.08). Resistance training increased both grip strength (weighted mean difference [WMD] 4.71 kg, 95% CI [2.42–6.99], p < 0.00001) and knee extension strength (WMD 3.93 kg, 95% CI [0.59–7.28], p = 0.02) significantly. Aerobic training improved grip strength (WMD 7.70 kg, 95% CI [3.35–12.05], p= 0.005) and the time of finishing short version of the sit-to-stand test (STS; WMD –4.69 s, 95% CI [–9.01 to –0.38], p = 0.03) but with insufficient evidence. In the dimension of physical performance, both aerobic training and resistance training have some beneficial effect on improving the score of 6-min walking test (WMD 85.76 m, 95% CI [63.43–108.09], p < 0.00001; WMD 41.92 m, 95% CI [8.06–75.75], p = 0.02, respectively) and median version of STS test (WMD 4.30 repetitions, 95% CI [1.22–7.39], p = 0.006; WMD 2.60 repetitions, 95% CI [0.64–4.56], p = 0.006, respectively). Conclusions: Regular resistance training with a moderate to high intensity may lead to improvement in muscle mass and muscle strength of patients undergoing dialysis, especially for the trained muscles. Both aerobic training and resistance training may help dialysis patients improve physical performance.

Nutritional Interventions

Abstract Background Health-promoting interventions are important for preventing frailty and sarcopenia in older adults. However, there is limited evidence that nutritional interventions yield additional effects when combined with resistance training. This systematic review and meta-analysis aimed to compare the effectiveness of nutritional interventions with resistance training and that of resistance training alone. Methods Randomized controlled trials published in peer-reviewed journals prior to July 2020 were retrieved from databases and other sources. The articles were screened according to the inclusion and exclusion criteria. The methodological quality of the included studies was assessed using Cochrane’s risk of bias tool 2. A meta-analysis was performed using the RevMan 5.4 program and STATA 16 program. Results A total of 22 studies were included in the meta-analysis. The results of the meta-analysis showed no significant differences between groups in muscle mass, muscle strength, or physical functional performance. In the subgroup analysis regarding the types of nutritional interventions, creatine showed significant effects on lean body mass (n = 4, MD 2.61, 95% CI 0.51 to 4.72). Regarding the other subgroup analyses, there were no significant differences in appendicular skeletal muscle mass (p = .43), hand grip strength (p = .73), knee extension strength (p = .09), chair stand test results (p = .31), or timed up-and-go test results (p = .31). In the meta-regression, moderators such as the mean age of subjects and duration of interventions were not associated with outcome variables. Conclusions This meta-analysis showed that nutritional interventions with resistance training have no additional effect on body composition, muscle strength, or physical function. Only creatine showed synergistic effects with resistance training on muscle mass. Trial registration CRD42021224843.
