Neural
At 60% of 1RM squat, both fast and slow eccentric conditions produced greater peak concentric velocity (PCV) than normative duration.
Using faster eccentric phases may enhance peak performance in squats.

At 60% of 1RM squat, both fast and slow eccentric conditions produced greater (p < 0.001) PCV than normative duration.
Why this rating
Supported by statistical significance.

More from this paper
- Eccentric duration was significantly and inversely correlated with average concentric velocity (ACV) at 60% (r = −0.408, p = 0.004) and 80% (r = −0.477, p = 0.001) of 1RM squat.Strong
- Eccentric duration had no impact on rating of perceived exertion (RPE), range of motion (ROM), or barbell path.Strong
