The Claim

Eccentric training performed at 180°/s is associated with the greatest increases in isokinetic strength compared to all other training conditions in untrained young adults following an 8-week intervention, suggesting that fast eccentric contractions may be particularly effective for improving strength.

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.

In plain English

If you're new to working out and do leg exercises where you lower the weight slowly and quickly, doing it at a speed of 180 degrees per second might give you the biggest strength gains after 8 weeks — faster eccentric moves might just be the secret sauce for getting stronger.

What the research says

1 study
  1. Study: The effects of eccentric and concentric training at different velocities on muscle hypertrophy

    This study found that doing slow-motion strength exercises with the muscle lengthening (eccentric) at a fast speed (180°/s) made people stronger than any other method tested — exactly what the claim says.
