Key Takeaway
Consider exercise for improving adiposity and mobility in sarcopenic obesity, but note low certainty of evidence.

This umbrella review synthesized evidence from systematic reviews regarding exercise-based interventions, including resistance training and multicomponent programs, for middle-aged and older adults with sarcopenic obesity. The analysis focused on body composition and physical function outcomes.

Findings indicate that exercise-based interventions were directionally favorable across all eight reviewed studies for adiposity outcomes. Physical function outcomes were generally favorable, specifically regarding grip strength and gait or mobility-related performance. Resistance training provided the most consistent signal for strength-related improvements, while multicomponent programs showed hypothesis-supporting but not definitive signals for adiposity and mobility.

Several limitations impact the certainty of these findings. The review corpus was methodologically weak, and there was high primary-study overlap (CCA = 0.238). Furthermore, evidence regarding muscle mass outcomes was mixed, while metabolic and inflammatory outcomes were sparse and inconsistent. Umbrella-level outcome certainty was judged low or very low.

Clinical application should be cautious. While exercise-centered interventions may improve adiposity and functional outcomes in this population, there is currently insufficient evidence to support specific modality ranking or comparative effectiveness claims.

Living with sarcopenic obesity means dealing with the dual challenge of excess body fat and a loss of muscle mass. This combination often makes it harder for middle-aged and older adults to stay mobile and active. A large review of existing studies looked at how different types of exercise affect these specific health goals.

The findings show that exercise programs generally lead to better body composition and improved physical functions, such as grip strength and mobility. Specifically, resistance training showed the most consistent results for building strength. While combined exercise programs also showed promise for improving both fat levels and movement, the evidence for metabolic changes was less consistent across the studies.

While these results are encouraging, it is important to note that the data comes from a wide variety of sources with varying levels of certainty. Because the research is based on a collection of different studies, we cannot yet say which specific type of exercise is definitively best compared to others. Talk to a healthcare provider to find the safest and most effective routine for your personal needs.

What this means for you:
Exercise programs can improve muscle strength and body composition in older adults with sarcopenic obesity.

Common questions

What kind of exercise is most effective for muscle loss?

Resistance training showed the most consistent signal for improving strength. While combined or multicomponent exercises also showed some promise for improving mobility and body composition, the evidence is not yet definitive enough to rank one specific method as superior to another.

Can exercise help with weight and fat levels?

Yes, results were directionally favorable across all eight reviews regarding adiposity outcomes. This means that exercise programs generally showed a positive trend in helping manage body fat for middle-aged and older adults with sarcopenic obesity.

How does exercise affect mobility and grip strength?

Exercise was found to be generally favorable for physical function, especially regarding grip strength and performance related to gait or mobility. These improvements are important for maintaining independence in middle-aged and older adults.

IntroductionSarcopenic obesity (SO) is an increasingly important nutrition- and exercise-relevant phenotype in middle-aged and older adults, but the secondary evidence base is complicated by heterogeneous SO definitions, mixed exercise and nutrition interventions, and repeated use of the same primary trials across reviews.MethodsWe conducted an umbrella review of systematic reviews with pairwise meta-analysis or network meta-analysis. PubMed, Web of Science, SPORTDiscus, Cochrane Library, Embase and Scopus were searched from inception to 1 March 2026. Eligible reviews focused on middle-aged and/or older adults with SO and reported quantitative syntheses for body composition and/or physical function. Broader non-pharmacological reviews were retained only when exercise-related quantitative syntheses were separately reported and extractable. Two reviewers independently screened records, extracted review-level data and assessed methodological quality with AMSTAR-2; disagreements were resolved by discussion and, where necessary, third-reviewer adjudication. Primary-study overlap was quantified using the corrected covered area (CCA).ResultsEight reviews met strict exercise-based eligibility criteria, including seven pairwise meta-analyses and one network meta-analysis. They represented 33 unique primary-study units and 88 review-level primary-study occurrences. Primary-study overlap was very high (CCA = 0.238). AMSTAR-2 confidence was low in seven reviews and critically low in one, and umbrella-level outcome certainty was judged low or very low. Adiposity outcomes were directionally favorable across all eight reviews, and physical-function outcomes were generally favorable, particularly for grip strength and gait- or mobility-related performance. Muscle-mass outcomes were mixed, while metabolic and inflammatory outcomes were sparse and inconsistent. Resistance training showed the most consistent strength-related signal, whereas combined or multicomponent exercise provided hypothesis-supporting, not definitive, signals when adiposity and mobility targets were considered together.DiscussionExercise-centered interventions may be associated with improvements in adiposity and functional outcomes in middle-aged and older adults with SO; however, clinical, modality-ranking and comparative-effectiveness claims should remain cautious because the review corpus is methodologically weak and highly overlapping.Systematic review registrationPROSPERO CRD420261370155, https://www.crd.york.ac.uk/PROSPERO/view/CRD420261370155
