The Claim
Interrepetition rest periods in bench press training result in higher velocity loss in moderate and high volume groups compared to low volume groups, indicating that fatigue accumulation is volume-dependent even when total work is matched per session.
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.
When performing bench presses with shorter rest periods between repetitions, moderate and high volume training sessions cause greater reductions in bar speed than low volume sessions, even when the total amount of work performed is the same.

When more reps are done in a set with short breaks, muscles produce more waste products like lactic acid and hydrogen ions. These chemicals build up faster than they can be cleared, making it harder for muscle fibers to contract strongly, so the bar slows down.
What the research says
1 studyWhen people do more reps in a bench press set with short breaks between each rep, their bar slows down more by the end — meaning they get more tired. This study showed that doing more reps leads to more slowing, even if everyone trained the same way.
