Combined Exercise and Nutrition Interventions Boost Physical Function in Nursing Home Residents
A systematic review finds that pairing resistance training with nutritional support improves strength, balance, and gait speed in older adults in long-term care.
Summary
As populations age, more older adults are living in long-term care facilities where physical decline and malnutrition are common. This systematic review examined seven studies testing combined lifestyle interventions — pairing physical exercise (resistance, balance, or multicomponent training) with nutritional supplementation or education — in adults aged 65 and older residing in care homes. Programs lasting 7 to 26 weeks generally improved gait speed, muscle strength, and balance. Nutritional status also improved when protein- and energy-enriched supplements were included. However, effects on quality of life were inconsistent across studies, and significant variation in study design made direct comparisons difficult. The findings support combining exercise and nutrition as a feasible and beneficial strategy for institutionalized older adults, though more standardized, longer-term trials are needed to establish best practices.
Detailed Summary
The rapid growth of aging populations worldwide has dramatically increased the number of older adults living in long-term care (LTC) facilities such as nursing homes. These settings present a concentrated opportunity to address two major drivers of functional decline in late life: physical inactivity and nutritional insufficiency. Lifestyle medicine — intervening on both simultaneously — holds promise for preserving healthspan in this vulnerable population.
This systematic review, conducted according to PRISMA guidelines, searched PubMed and Scopus through December 2024 to identify trials of combined lifestyle interventions in LTC residents aged 65 and older. From 3,093 initial records, seven studies met inclusion criteria. Interventions combined resistance training, balance exercises, or multicomponent physical programs with nutritional supplementation or dietary education, and ranged in duration from 7 to 26 weeks.
The majority of studies reported meaningful improvements in physical functionality, specifically gait speed, grip or lower-limb strength, and balance — all critical predictors of fall risk, independence, and mortality in older adults. When interventions included protein- and energy-enriched nutritional supplements, nutritional status also improved. Effects on quality of life were less consistent, varying across measurement tools and intervention types.
For clinicians and care facility administrators, these findings reinforce that even relatively short multimodal programs can produce measurable functional gains in frail, institutionalized older adults. Resistance training paired with adequate protein intake appears to be a particularly potent combination for preserving muscle mass and mobility.
Key caveats temper enthusiasm: only seven studies met inclusion criteria, and substantial heterogeneity in study design, intervention protocols, duration, and outcome measures limits the ability to draw firm conclusions or issue specific prescriptions. High-quality, standardized, longer-duration trials with harmonized outcome measures are urgently needed to confirm effectiveness and guide implementation at scale.
Key Findings
- Combined exercise and nutrition programs improved gait speed, strength, and balance in most LTC residents studied.
- Protein- and energy-enriched supplementation was associated with improved nutritional status in care home residents.
- Intervention durations of 7–26 weeks were generally sufficient to produce measurable physical functional gains.
- Quality-of-life outcomes were inconsistent across studies, indicating more work is needed on psychosocial measures.
- Only 7 of 3,093 screened studies met inclusion criteria, highlighting a significant gap in rigorous LTC research.
Methodology
Systematic review following PRISMA guidelines, searching PubMed and Scopus through December 2024. Inclusion required adults aged 65 or older in LTC facilities receiving multidomain lifestyle interventions combining physical exercise and nutrition. Seven studies were ultimately included from 3,093 screened records.
Study Limitations
The review is based on only seven studies with considerable heterogeneity in intervention design, duration, and outcome measures, limiting comparability and generalizability. This summary is based on the abstract only, as the full text was not available (not open access). No meta-analysis was possible due to study variability, and long-term sustainability of observed benefits remains unestablished.
