The evidence base.
Plain-language summaries of the science on sarcopenia prevention, resistance training in older adults, and healthy aging in Canada. Written for adults 55–70 and their families. Educational only — not medical advice.
What is sarcopenia, and why does muscle loss accelerate after 50?
Age-related muscle loss is gradual, common, and largely preventable — but most people have never heard the word for it.
Read summary →Why resistance training is the highest-leverage prevention for muscle loss
Decades of randomized trials point to the same conclusion: lifting against resistance, progressively, is what rebuilds aging muscle.
Read summary →Protein and muscle in older adults: what the evidence supports
Aging muscle responds less readily to protein — which is why both how much and how it is paired with training matter.
Read summary →Falls, frailty, and independence: the case for prevention
Strength is not about athletics in later life — it is about staying out of hospital and living on your own terms.
Read summary →Canada's physical-activity guidelines for older adults, explained
The national guidelines already recommend muscle-strengthening twice a week. Most older Canadians do not meet it.
