MoveSTroNg Program Tests Exercise and Nutrition Support for Frail Older Adults
A feasibility trial combines strength training, balance work, and protein education to help frail older adults with chronic disease stay functional.
Summary
The MoveSTroNg trial tested whether a structured exercise and nutrition program could realistically be delivered to community-dwelling older adults living with chronic conditions like diabetes and frailty. Researchers from the University of Waterloo enrolled 44 participants and measured how well the program could be implemented in real-world settings, tracking referral rates, recruitment success, and how many participants stayed engaged over time. The intervention paired strength and balance training — led by credentialed exercise professionals — with nutrition education focused on adequate protein intake, addressing a commonly overlooked gap: starting exercise without enough dietary protein can cause muscle loss rather than gain. The trial was completed in 2020 and represents an important step toward scalable, community-based programs that go beyond generic fitness classes to meet the specific needs of aging adults.
Detailed Summary
As the global population ages, maintaining physical function in older adults with chronic conditions has become a pressing public health priority. Yet many community exercise programs lack the expert guidance, progressive structure, and nutritional support needed to produce meaningful results in frail or medically complex individuals. The MoveSTroNg program was designed to address exactly this gap.
Researchers at the University of Waterloo conducted a feasibility trial enrolling 44 older adults with chronic diseases including diabetes and frailty. The intervention combined structured strength and balance training — delivered by credentialed exercise professionals — with a nutrition education component emphasizing adequate protein intake. A usual care control group provided a comparison baseline. The primary outcomes were implementation feasibility metrics: referral rates, recruitment success, and participant retention and adherence throughout the program.
Feasibility trials like this are critical precursors to larger efficacy studies. By testing real-world delivery conditions, the team aimed to identify barriers to uptake — such as fear of injury, low exercise self-efficacy, and inadequate dietary protein — before scaling the intervention. The protein component is particularly noteworthy: research consistently shows that initiating resistance training in a protein-deficient state can blunt muscle gains and even accelerate lean mass loss in older populations.
The trial was completed in September 2020, with results pending full publication. If feasibility targets were met, MoveSTroNg could serve as a replicable model for community health systems seeking to deliver evidence-based exercise and nutrition programming to high-risk older adults.
Key caveats include the small sample size of 44 participants and the feasibility-focused design, which was not powered to detect changes in strength, function, or clinical outcomes. Additionally, this summary is based on the abstract only, and full results have not yet been reviewed.
Key Findings
- Feasibility of real-world delivery of combined exercise and nutrition programming for frail older adults was the primary outcome.
- Program paired credentialed-led strength and balance training with protein-focused nutrition education.
- Inadequate protein intake before starting exercise can cause muscle loss rather than gain in older adults.
- Low exercise self-efficacy and fear of injury were identified as key barriers the program aimed to address.
- 44 participants with chronic disease including diabetes and frailty were enrolled across the trial.
Methodology
This was a feasibility randomized controlled trial enrolling 44 older adults with chronic conditions, comparing the MoveSTroNg intervention (strength and balance training plus nutrition education) to usual care. Primary outcomes were implementation metrics including referral rates, recruitment, retention, and adherence rather than clinical efficacy endpoints. The trial was conducted by the University of Waterloo and ran from September 2019 to September 2020.
Study Limitations
This summary is based on the abstract only, as the full trial results are not yet publicly available for review. The trial enrolled only 44 participants and was designed to assess feasibility rather than clinical efficacy, so no conclusions about strength or functional outcomes can yet be drawn. The single-site academic sponsorship and small sample may limit generalizability to diverse community settings.
