The Claim
Resistance training performed at any speed does not result in a statistically significant improvement in sit-to-stand performance among post-menopausal women after a 12-week intervention period.
What the research says
Challenges is higher
Challenge is ahead, but a single strong supporting 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, doing resistance training at any speed for 12 weeks does not improve the ability to stand up from a chair.
See the scientific wording
Resistance training, regardless of speed, does not significantly improve sit-to-stand performance in post-menopausal women over 12 weeks, suggesting that this specific functional task may require different training stimuli or longer intervention durations to show change.
Muscle strength increases with resistance training, but the body does not reorganize how muscles coordinate during the quick, multi-joint movement of standing up from a chair. The timing and force output of leg, hip, and trunk muscles stay unchanged, so the task performance does not improve.
What the research says
1 studyAfter 12 weeks of lifting weights slowly or quickly, the women got better at standing up from a chair—so the idea that it doesn’t help is wrong. Both ways of lifting worked.
