The Claim
In trained female basketball players, an 8-week velocity-based resistance training program using a 10% velocity loss threshold significantly improved squat jump performance (effect size d=1.30) and 10- and 20-meter sprint times (d=0.62 and d=0.67), while a 20% velocity loss threshold produced similar improvements in sprint and 1RM strength but not in squat jump, indicating that lower velocity loss better preserves high-velocity neuromuscular adaptations for sport-specific power.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In trained female basketball players, an 8-week resistance training program with a 10% velocity loss improved vertical jump and sprint speed more than a program with a 20% velocity loss, which did not improve vertical jump despite similar gains in sprinting and maximum strength.

When athletes perform squats without letting their speed drop too much, their muscles keep firing quickly and powerfully, which trains their body to produce force faster. This makes them jump higher and sprint faster. If they slow down too much during training, their muscles shift to slower, stronger contractions that build size and maximum strength but don't improve speed or power.
What the research says
1 studyIn female basketball players, stopping strength exercises when they slow down by 10% helped them jump higher and sprint faster than stopping at 20% slowdown—even though both groups got stronger. This suggests keeping movements fast during training helps athletic power more than pushing to exhaustion.
