The Claim
Whole-body low-intensity resistance training with slow movement and tonic force generation (LST) performed twice weekly for 13 weeks in young untrained men increases muscle thickness by approximately 6.8% and one-repetition maximum strength by approximately 33%, comparable to high-intensity normal-speed resistance training (HN), which increased muscle thickness by 9.1% and strength by 41.2%, with no significant differences between the two training methods.
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.
Doing gentle weight training slowly twice a week for 13 weeks makes young men's muscles about 7% bigger and 33% stronger, almost as much as regular heavy lifting, which made muscles 9% bigger and 41% stronger.

What the research says
1 studyThe study tested the exact same slow-motion weight training described in the claim and found it builds muscle and strength almost as well as regular fast training, just like the claim says.
