When women do fast weightlifting exercises, they get much stronger compared to slow lifting, but men don't see much difference between fast and slow lifting.

Lifting weights faster or normally gives you more strength gains than lifting weights very slowly, especially for healthy adults.

Men tend to get stronger faster than women when lifting very heavy weights, possibly due to differences in how their muscles and nerves respond to intense training.

Whether you're young or old doesn't really change how fast or slow weight training affects your strength gains. Young people might get a tiny extra boost from fast lifting, but for older folks, it doesn't make much difference either way.

Whether you're new to lifting weights or experienced, how fast you lift doesn't really change how much stronger you get. Both groups got a tiny bit stronger with fast lifting, but it wasn't a clear or big difference.

For young women lifting weights, how much total work you do might matter more for building muscle and strength than how heavy the weights are, because studies show similar results when the total effort is the same but intensity differs.
