The Claim
High-speed resistance training produces equivalent increases in maximal muscle strength (as measured by 1RM leg press and bench press) compared to low-speed resistance training in post-menopausal women, when total work per session is reduced by 20%.
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 post-menopausal women, lifting weights quickly builds the same amount of maximal strength as lifting slowly, even when the total amount of work done in each session is 20% lower.
See the scientific wording
High-speed resistance training achieves similar gains in maximal muscle strength (1RM leg press and bench press) as low-speed resistance training in post-menopausal women, despite using 20% less total work per session, suggesting that training speed does not compromise strength development when volume is adjusted.
Lifting weights quickly trains the nervous system to fire muscle signals faster and more in sync, so even with less total effort, the muscles still get strong enough to lift heavy weights.
What the research says
1 studyOlder women who lifted weights quickly got just as strong as those who lifted slowly—even when they did less total work—so speed doesn’t hurt strength gains if you adjust how much you lift.
