The Claim

In adults over 60 years of age, resistance training frequency is not significantly associated with muscle hypertrophy, as no statistically significant effect was found (p = 0.67), suggesting that increasing training days does not meaningfully influence muscle growth in this population.

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.

Correlation

In plain English

For adults over 60, doing more resistance training sessions per week does not lead to greater muscle growth compared to fewer sessions, based on measured outcomes with no statistically significant difference.

See the scientific wording

In adults over 60 years of age, resistance training frequency is not significantly associated with muscle hypertrophy, as no statistically significant effect was found (p = 0.67), suggesting that increasing training days does not meaningfully influence muscle growth in this population.

Why this might work

In older adults, muscles reach a point where they can't make more protein no matter how often they are trained, so doing more workouts doesn't make them grow bigger.

    For people over 60, doing resistance training more often doesn’t seem to make muscles bigger, according to this big review of studies. More workouts helped strength a little, but not muscle size.
