The Claim

In intermediate-trained women, higher velocity loss thresholds (e.g., VL50) reduce the ability to maintain movement velocity across submaximal loads, while lower velocity loss thresholds (VL0 and VL25) maintain or increase high-velocity performance.

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

In intermediate-trained women, lifting with higher velocity loss limits reduces the ability to maintain speed during submaximal lifts, while lower velocity loss limits preserve or improve speed performance.

See the scientific wording

In intermediate-trained women, higher velocity loss thresholds (e.g., VL50) impair the ability to maintain movement velocity across submaximal loads, while lower thresholds (VL0 and VL25) preserve or enhance high-velocity performance, suggesting a trade-off between hypertrophy and explosive power.

Why this might work

When lifting weights with moderate fatigue, the nervous system stays sharp and recruits muscle fibers faster, making quick movements stronger. When lifting until very tired, the muscles change to slower-twitch fibers that can't contract fast, and the nervous system gets worn out, making quick movements slower.

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

    Training until you're very tired (VL50) helped women get stronger and build more muscle, but didn’t make them slower with lighter weights. Training with just a little fatigue (VL25) actually made them faster and more powerful when lifting light weights quickly.
