Mixed

Higher velocity loss thresholds (>25%) do not produce superior muscle hypertrophy compared to moderate velocity loss (20-25%).

For resistance-trained individuals, stopping sets at moderate velocity loss (20-25%) is just as effective for muscle growth as stopping at high velocity loss (>25%). You can simplify your training by not obsessing over precise velocity loss metrics.

no statistically significant difference between high velocity loss and moderate velocity loss conditions on muscle hypertrophy, revealing a trivial standardised effect [ES = 0.08 (95% CI − 0.16, 0.32), p = 0.529]
