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 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.

Randomized Controlled TrialHuman
After 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.
Quality-weighted scoring: we follow the GRADE framework — each study is rated High, Moderate, Low, or Very Low based on study design, methodology rigor, and risk of bias. A single high-quality RCT can outweigh several weaker observational studies.
Scores reflect study quality, not just count.
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.

Mechanism
1 studyLifting weights makes muscles stronger, but it doesn't teach the body how to use those muscles faster or in the right order to stand up from a chair. The muscles get bigger and can push harder, but the timing and coordination needed for standing don't 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.
Resistance training increases muscle cross-sectional area and maximal force production in the quadriceps, gluteus maximus, and hamstrings.
Neural drive to these muscles during maximal voluntary contractions increases, but the spatiotemporal pattern of muscle activation during the sit-to-stand task remains unchanged.
The coordination between hip extension, knee extension, and trunk control during the sit-to-stand movement does not become more efficient or faster.
The rate of force development during the initial phase of standing does not increase sufficiently to reduce the time required to complete the task.
