For older lifters, moving fast may beat moving slow when everyday function is the goal

Resistance training is a mainstay of healthy ageing, but there is more than one way to lift. Conventional resistance training uses slow, controlled movement, while power training performs the lifting phase at high velocity to train the ability to produce force quickly — a quality closely tied to real-world tasks like rising from a chair or catching a stumble. Which approach better preserves everyday function in older people is a genuinely practical question, and this systematic review set out to answer it by directly comparing the two in community-dwelling older adults.

The reviewers searched the Cochrane Central Register of Controlled Trials, PubMed, EMBASE, CINAHL, PEDro and Google Scholar for randomised or quasi-randomised trials comparing high-velocity power training with conventional low-velocity resistance training in people over 60 living in the community. Eleven trials involving 377 participants were identified. The primary outcomes were measures of function; secondary outcomes included balance, gait, strength, power, muscle volume and adverse effects, and results were pooled as effect sizes across trials.

The pooled effect size for follow-up values of functional outcomes was 0.32 in favour of power training (95% CI 0.06 to 0.57) — a small but statistically significant advantage. Other estimates were less decisive: the pooled effect for change values was 0.38 but with a wide confidence interval crossing zero (95% CI -0.51 to 1.28), and self-reported function from three studies favoured power training at 0.16, also non-significant (95% CI -0.17 to 0.49). The authors concluded power training is feasible for older people, but that no firm conclusion could be made about safety.

This meta-analysis supports the idea that movement velocity is a meaningful training variable in older age, not just load. It extends the conventional wisdom that older adults should strength train by suggesting how they lift may also matter for functional outcomes, while stopping short of a strong verdict: the advantage was small, only the follow-up analysis reached significance, and the safety of high-velocity lifting in this population was not resolved. Larger trials with consistent functional measures and systematic adverse-event reporting would be needed to firm up the comparison.

For anyone thinking about strength work in later life — for themselves or a parent — this is a reason to see intentional movement speed as a legitimate part of the conversation, alongside how heavy and how often. The pooled data suggest fast-velocity training was feasible for over-60s and carried a small edge for everyday function over traditional slow lifting. The caveats matter, though: the advantage was modest, some analyses did not reach significance, and the evidence on safety was insufficient to draw conclusions.
