Key Takeaway
Interpret digital exercise benefits cautiously given very low to moderate certainty.
This meta-analysis examined digital health-based exercise interventions for managing sarcopenia in adults aged 60 and older. It included 927 participants and assessed multiple outcomes including muscle mass, muscle strength, balance ability, walking performance, physical function, and quality of life.
Pooled analyses showed potential improvements in muscle mass (MD = 0.25, 95% CI 0.03 to 0.46; 95% PI -0.36 to 0.85), muscle strength (MD = 2.14, 95% CI 1.18 to 3.11, P < 0.001), balance ability (SMD = 0.31, 95% CI 0.12 to 0.51, P = 0.001), walking performance (SMD = 0.55, 95% CI 0.21 to 0.89; 95% PI -0.70 to 1.79), and physical function (SMD = 0.89, 95% CI 0.08 to 1.71; 95% PI -2.33 to 4.12). No significant improvement was found for quality of life (SMD = 0.08, 95% CI -0.19 to 0.35, P = 0.53).
The authors rated the certainty of evidence as very low to moderate and noted that true effects may differ substantially from observed estimates. Adverse events, serious adverse events, discontinuations, and tolerability were not reported. Follow-up duration and funding or conflicts of interest were also not reported.
These findings suggest that digital exercise interventions show potential for managing sarcopenia in older adults, but the very low to moderate certainty of evidence and wide prediction intervals warrant cautious interpretation. Clinicians should recognize that the evidence is not definitive and that true effects may differ substantially from observed estimates.
How this fits prior evidence
This meta-analysis extends prior coverage of exercise-based strategies for sarcopenia, including the finding that protein supplementation added to exercise improves grip strength and muscle mass in older adults with sarcopenia. It also aligns with the broader recognition that sarcopenia is associated with poorer outcomes in conditions such as head and neck cancer, liver cirrhosis, and diabetic foot. Unlike prior coverage of Kampo medicine as a hypothesis-generating complementary approach, this review focuses on digital exercise interventions and provides pooled estimates, though with very low to moderate certainty.
Researchers looked at how digital health-based exercise programs affect older adults aged 60 and over who have sarcopenia, which is the loss of muscle mass and strength. This review combined data from 927 participants to see if these digital tools could help manage physical decline.
The findings suggest that these digital programs may lead to improvements in muscle strength, balance, and walking performance. They also showed potential benefits for overall physical function. However, the study did not find a significant link between these programs and an improvement in the overall quality of life.
It is important to note that the evidence for these findings is currently of low to moderate certainty. Because the data is not definitive, the actual results for an individual may differ from what was seen in this study. These findings suggest that digital tools could be a helpful way to manage muscle loss, but they are not a guaranteed fix.
What this means for you:
Digital exercise programs may improve strength and balance in older adults, though evidence certainty is currently low.
Common questions
What are the benefits of digital exercise for sarcopenia?
Digital exercise programs may lead to potential improvements in muscle strength, balance ability, and walking performance for adults aged 60 and older. They also show potential for improving physical function. However, the study did not find a significant change in quality of life.
Is the evidence for these digital programs strong?
The evidence for these findings is currently of very low to moderate certainty. This means that while the results show potential for improvement in muscle strength and balance, the data is not yet definitive enough to guarantee specific results for every individual.
Who can benefit from these digital exercise interventions?
These interventions were studied in adults aged 60 and older who have sarcopenia. The goal is to help these individuals manage muscle loss and improve their physical function and walking performance through digital health-based tools.
BACKGROUND: Sarcopenia, the progressive loss of muscle mass and function, impairs independence in older adults. Digital health exercise interventions are scalable solutions for older adults with sarcopenia. This systematic review and meta-analysis aimed to synthesize the evidence on their efficacy in populations with clinically diagnosed sarcopenia and identify influential intervention characteristics associated with treatment outcomes.
METHODS: We systematically searched PubMed, EMBASE, Web of Science, Cochrane Library, CINAHL, CNKI, and Wanfang on May 20, 2026, with no date restrictions. We included randomized controlled trials involving adults aged ≥60 with sarcopenia receiving digital exercise interventions. Two reviewers independently screened studies, extracted data, and assessed risk of bias; analyses were performed using R and Review Manager.
RESULTS: Fourteen trials (n = 927) were included. Digital interventions showed potential improvements in muscle mass (MD = 0.25, 95%CI:0.03-0.46, 95% PI:-0.36 to 0.85), muscle strength (MD = 2.14, 95% CI:1.18-3.11, P < 0.001), balance ability (SMD = 0.31, 95% CI:0.12-0.51, P = 0.001), walking performance (SMD = 0.55, 95% CI:0.21-0.89, 95% PI:-0.70 to 1.79), and physical function (SMD = 0.89, 95% CI:0.08-1.71, 95% PI:-2.33 to 4.12), but not quality of life (SMD = 0.08, 95% CI:-0.19 to 0.35, P = 0.53). Exploratory subgroup analyses suggested that factors such as supervision, program duration, and measurement tools may influence outcomes; however, formal tests for subgroup differences were generally non-significant, and consistent patterns across all metrics were not observed.
CONCLUSION: Digital exercise interventions show potential for managing sarcopenia in older adults, though the very low to moderate certainty of evidence indicates that true effects may differ substantially from observed estimates. This review explores potential roles of intervention design, supervision, and multimodal delivery. Future research should adopt rigorous designs and longer follow-up to validate results and enhance clinical application.
