For lifters over 60, more training volume means more strength

Ageing strips away strength and muscle mass, and with them the functional capacity that keeps people independent. Resistance training is the standard countermeasure, but a practical question has stayed unresolved: how much training do older people actually need? Some argue that minimal doses suffice and that high volumes risk being burdensome, while others hold that more work drives more adaptation at any age. This review set out to compare different resistance training volumes head-on for their effects on strength, functional fitness and body composition in older adults.

The authors systematically searched eight databases plus Google Scholar for studies comparing different resistance training volumes in older people. Thirty-one studies were included, encompassing 1,744 participants, with individual study samples ranging from 18 to 376 people and averaging 56. Participants were aged 60 to 83. Separate meta-analyses were run for each outcome using random effects models, with results expressed as standardised mean differences and subgroup analyses by intervention length in weeks.

High-volume resistance training produced significantly greater strength adaptations than low-volume training in both the upper limbs and the lower limbs, with effects in the small to moderate range. The superiority of higher volumes became more pronounced after 12 weeks of training, suggesting the advantage compounds as programmes lengthen. For functional fitness, everyday capability rather than raw strength, there was a tendency favouring high volume that fell short of a definitive result. The clearest conclusion applies to independent older adults on longer interventions.

This pushes back on the idea that minimal-dose training is all older adults need, at least where maximal strength is the goal. It aligns with dose-response thinking from younger populations while grounding it in data from people aged 60 to 83. Open questions remain: the analysis does not define a precise set count separating high from low volume, the functional fitness signal needs confirming, and the findings concern independent older adults rather than frail ones.

This is a reason to think that in later life, the amount of resistance training matters, not merely whether it happens, and that the payoff for higher volumes grows with time under a programme. It also suggests patience: the advantage was clearest beyond 12 weeks, so short trials of a routine may understate what more work delivers. What counts as the right volume for any individual remains unanswered by this analysis.
