The Claim

In intermediate-trained women performing bench press training with loads of 70–85% 1RM over 8 weeks, a velocity loss threshold of 25% results in greater improvements in rapid force production and neuromuscular activation during high-velocity movements compared to velocity loss thresholds of 0% or 50%.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Cause and effect
1 study reviewed
In plain English

Intermediate-trained women who lift weights at 70–85% of their maximum strength for 8 weeks and stop sets when they slow down by 25% show greater gains in explosive power and muscle activation during fast movements than those who stop when they slow down by 0% or 50%.

See the scientific wording

In intermediate-trained women performing bench press training with loads of 70–85% 1RM over 8 weeks, a velocity loss threshold of 25% improves rapid force production and neuromuscular activation during high-velocity movements more than thresholds of 0% or 50%, indicating that moderate fatigue enhances explosive strength adaptations.

Why this might work

When muscles are trained with moderate fatigue, the nervous system learns to recruit more muscle fibers faster and fire them more intensely during quick movements. This makes the muscles generate force more rapidly. Too little fatigue doesn't challenge the nervous system enough, and too much fatigue causes the muscles to change into slower types that can't contract quickly, reducing explosive power.

  1. Study: Effects of different velocity loss thresholds on strength, neuromuscular adaptations, and muscle hypertrophy during bench press training in women

    For women who already lift weights, stopping bench press sets when their speed drops by 25% helps them punch or push faster afterward—better than stopping after just one rep or going until they’re totally exhausted.
