The Claim
For older adults, performing more than two weekly resistance training sessions provides no additional benefit for muscle hypertrophy and only a small improvement in maximal strength.
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.
In older adults, doing more than two resistance training sessions per week does not increase muscle size and only slightly improves maximum strength.
See the scientific wording
Based on the finding that muscle hypertrophy is unaffected by training frequency and maximal strength shows only a small improvement with increased frequency, it is suggested that more than two weekly resistance training sessions are unlikely to provide additional benefits for older adults.
After two weekly training sessions, muscles reach their maximum rate of building new protein, and nerves can't activate more muscle fibers than they already are. Doing more sessions doesn't make muscles grow bigger or stronger because the body has already used up its capacity to respond.
What the research says
1 studyThis study found that doing strength training more than twice a week doesn’t make older adults’ muscles much bigger, and only gives a tiny boost to strength. So, training more often probably isn’t worth the extra effort.
