Is this trial a fit for you?

Likely a good fit

Ideal candidates are community-dwelling adults aged 65–85 in Nova Scotia who can safely do moderate-intensity exercise and are willing to take protein supplements and eat blueberries.

Probably not a fit

People who cannot safely exercise because of medical or cognitive limitations, or who are allergic to or refuse blueberries or protein powder, are unlikely to benefit from this intervention.

What this trial studies

This is a pragmatic randomized controlled trial that randomizes older adults to a packaged intervention called STRONG (protein supplements, blueberries, and supervised resistance plus aerobic training) or to continue their usual medical care. The intervention combines three components chosen for complementary biological effects on muscle, inflammation, and cardiovascular function. The main comparison will examine changes in frailty and cardiovascular health over a one-year intervention with an additional year of follow-up. Participants are enrolled at the QEII Health Sciences Centre in Halifax and must be able to participate in moderate-intensity exercise.

Why it matters

Potential benefit: If successful, the packaged intervention could reduce frailty and improve cardiovascular markers, potentially lowering complications and preserving independence in older adults.

How similar studies have gone: Previous studies show exercise, protein supplementation, and blueberries can each help muscle health or inflammation individually, but combining them into a single packaged intervention targeting both frailty and cardiovascular health is novel and largely untested.
