The Claim

Velocity-based strength training using a 20% velocity loss threshold for 8 weeks improves lower-limb maximal strength, explosive power, sprint speed, and muscle thickness in collegiate athletes, regardless of sex.

Cause and effect
1 study reviewed
In plain English

Eight weeks of velocity-based strength training with a 20% velocity loss threshold increases lower-limb maximal strength, explosive power, sprint speed, and muscle thickness in collegiate athletes of both sexes.

See the scientific wording

Velocity-based strength training using a 20% velocity loss threshold for 8 weeks improves lower-limb maximal strength, explosive power, sprint speed, and muscle thickness in collegiate athletes, regardless of sex, suggesting it is an effective method for enhancing multiple performance domains simultaneously.

Why this might work

Lifting weights with a speed-based limit keeps muscles under high tension for longer, which makes muscle fibers grow thicker and teaches the nervous system to fire more strongly, making the legs stronger, faster, and more powerful.

  1. Study: The effect of velocity-based strength training on lower limb maximal strength, power, and muscle thickness: a comparative study of sex-specific adaptations

    This study found that college athletes who did squat training with a speed-based stopping rule got stronger, jumped higher, ran faster, and built more thigh muscle—no matter if they were male or female. So yes, the training works for everyone in all those ways.
