The Claim
Faster concentric actions during resistance training result in greater power output compared to slower concentric actions.
What the research says
Not yet evaluated
We are still looking at what the research says.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Performing the upward phase of weightlifting movements more quickly can lead to higher power output than performing the same movements slowly.
See the scientific wording
Faster concentric actions during resistance training may enhance power output compared to slower concentric actions.
When you lift a weight quickly, your muscles generate force faster, which recruits more high-power muscle fibers and makes your body produce more power. This happens because the nervous system fires signals more rapidly to the muscles, and the muscle fibers themselves can't stretch out as much during the fast movement, so they push harder right away.

1 studyStudy: When duration matters: rethinking resistance training load through time under tension
Doing the lifting part of a weight exercise faster can make you more powerful, and this study says so — faster up-movements help generate more power than slow ones.
