The Claim

In young, trained men, resistance training with moderate loads (55–70% 1RM) and 10% velocity loss results in similar increases in maximal strength (1RM) and muscle endurance compared to training with 30% or 45% velocity loss, despite a 64% reduction in total repetitions performed.

In plain English

In young, trained men, lifting weights at moderate intensity with 10% velocity loss produces the same gains in maximum strength and muscle endurance as lifting with 30% or 45% velocity loss, even though the total number of repetitions is 64% lower.

See the scientific wording

In young, trained men, resistance training with moderate loads (55–70% 1RM) and 10% velocity loss produces similar gains in maximal strength (1RM) and muscle endurance as training with 30% or 45% velocity loss, despite performing 64% fewer total repetitions.

Why this might work

When people lift weights with controlled speed and stop before getting very tired, their maximum strength goes up. This makes the same weight feel lighter, so they can do more reps without getting exhausted. At the same time, avoiding slow, fatiguing reps keeps their fastest muscle fibers working at full speed, which helps them jump and sprint better.

  1. Study: Effect of velocity loss during squat training on neuromuscular performance

    Young men who stopped their squats when they slowed down just 10% got just as strong and enduring as those who kept going until they slowed down 30% or 45%—but they did way fewer reps. So, training less can be just as good—or even better—for strength and athletic performance.
