The Claim
In adults over 60 years of age, an increase in resistance training frequency by one day per week is associated with a 0.14 increase in effect size for maximal strength, with a 95% confidence interval of 0.08 to 0.21.
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.
For adults over 60, adding one extra day of resistance training per week is linked to a small but measurable increase in maximal strength.
See the scientific wording
In adults over 60 years of age, increasing resistance training frequency by one day per week is associated with a 0.14 increase in effect size for maximal strength, with a 95% confidence interval of 0.08 to 0.21, suggesting a small but statistically significant association between training frequency and strength gains.
Doing resistance training one more day a week gives muscles more chances to be activated under load, which trains the nervous system to recruit more muscle fibers with each effort, leading to stronger contractions over time.
What the research says
1 studyFor people over 60, doing resistance training one extra day a week leads to a tiny but real boost in strength, but not enough to make doing more than two days a week worth it.
