The Claim

In trained female basketball players, resistance training with 10% and 20% velocity loss thresholds both result in significant improvements in 1RM back squat strength and 10- and 20-meter sprint times, with no statistically significant difference between the two thresholds.

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

Quantitative

In plain English

Trained female basketball players who perform resistance training with either 10% or 20% loss of movement speed during lifts show equal and significant gains in squat strength and sprint performance over time.

See the scientific wording

In trained female basketball players, both 10% and 20% velocity loss thresholds during resistance training produce significant improvements in 1RM back squat strength and 10- and 20-meter sprint times, with no statistically significant difference between groups, indicating that moderate velocity loss may be sufficient for strength and sprint adaptations.

Why this might work

When athletes lift weights with moderate slowing, their muscles generate high force quickly at first, which trains their nerves to fire faster and more together, making them explode better. As the set continues and the muscles get tired, they grow bigger, especially the fast-twitch fibers that power sprints and heavy lifts. Both the faster nerve signals and the bigger muscles work together to make them stronger and faster, no matter if they stop when the lift slows 10% or 20%.

  1. Study: Effect of different velocity loss thresholds during a resistance training program on jump and sprint performances in trained female athletes

    Female basketball players who stopped their squat exercises when they slowed down by 10% or 20% both got stronger and sprinted faster after 8 weeks — and neither group did noticeably better than the other.
