The Claim
In intermediate-trained women, moderate velocity loss thresholds (VL25) during high-velocity bench press movements increase neuromuscular activation as measured by EMG amplitude, whereas higher velocity loss thresholds (VL50) do not produce similar increases in EMG amplitude.
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 intermediate-trained women, performing bench press movements with a 25% loss of velocity increases muscle electrical activity more than performing them with a 50% loss of velocity.
See the scientific wording
In intermediate-trained women, moderate velocity loss thresholds (VL25) enhance neuromuscular activation during high-velocity bench press movements, as evidenced by increased EMG amplitude, while higher thresholds (VL50) do not produce similar adaptations, suggesting optimal fatigue levels for neural efficiency.
When muscles are trained with moderate fatigue, the nervous system keeps firing signals strongly to the fast-twitch muscle fibers, making them contract faster and more forcefully during quick movements. Too much fatigue causes the muscle fibers to switch to slower types and the nervous system to fire less efficiently, reducing speed and power.
What the research says
1 studyWhen women train with moderate fatigue (stopping when the bar slows by 25%), their muscles fire more powerfully during fast lifts. But if they train until exhaustion (50% slowdown), their muscles get bigger and stronger overall, but don’t improve their fast-lift efficiency.
