The Claim

In untrained older men aged 60–75 years who consume at least 1.0 g/kg/day of protein, 12 weeks of supervised resistance training performed twice weekly leads to significant increases in leg press and chest press one-repetition maximum (1-RM) strength, with average gains of 28.3 kg (95% CI [19.63, 37.1]) and 10.9 kg (95% CI [5.50, 16.3]), respectively, regardless of whether 40 g of protein is ingested post-exercise or pre-sleep, indicating that resistance training alone is sufficient for substantial strength improvements without additional timed protein supplementation.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Cause and effect

In plain English

Older guys between 60 and 75 who aren't very active can get a lot stronger in just 12 weeks by lifting weights twice a week—even if they don’t take extra protein right after workouts or before bed, as long as they’re already eating enough protein overall.

See the scientific wording

In untrained older men aged 60–75 years consuming ≥1.0 g/kg/day of protein, 12 weeks of supervised resistance training twice weekly increases leg press 1-RM strength by an average of 28.3 kg (95% CI [19.63, 37.1]) and chest press 1-RM by 10.9 kg (95% CI [5.50, 16.3]), regardless of whether 40 g of protein is consumed post-exercise or pre-sleep, demonstrating that resistance training alone is sufficient to produce substantial strength gains without additional protein supplementation.

What the research says

1 study

  1. Study: Neither pre-sleep nor post-exercise protein consumption influences resistance exercise training adaptations in older adults

    The study found that older men gained the same amount of strength from lifting weights twice a week, whether or not they drank extra protein after workouts or before bed — as long as they already ate enough protein during the day.
