The Claim
In post-menopausal women, 12 weeks of high-speed resistance training results in a 28% improvement in ball-throwing performance and a 21% improvement in the 8-foot up-and-go test, which are significantly greater than the 23% and 13% improvements observed with low-speed resistance training.
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.
Among post-menopausal women, 12 weeks of high-speed resistance training produces greater improvements in functional power tests—such as throwing a ball and moving quickly over 8 feet—than 12 weeks of low-speed resistance training.
See the scientific wording
In post-menopausal women, 12 weeks of high-speed resistance training leads to a 28% improvement in ball-throwing performance and a 21% improvement in the 8-foot up-and-go test, which are significantly greater than the 23% and 13% improvements seen with low-speed resistance training, suggesting that explosive movement training may enhance functional power more effectively than slow, controlled movements in this population.
When movements are performed quickly, the nervous system activates more muscle fibers at the same time and fires them faster, allowing the muscles to generate force more rapidly. This enables faster and more powerful movements like throwing a ball or standing up quickly.
What the research says
1 studyIn older women, doing strength exercises quickly and powerfully improved their ability to throw a ball and stand up fast more than doing the same exercises slowly—even though both methods helped. The fast version worked better for these quick movements.
