The Claim
In untrained males performing knee extension exercises to muscle failure with moderate loads (50–60% 1RM), resistance training using a 6-second repetition duration leads to greater gains in maximal isometric strength at 30° of knee flexion compared to a 2-second repetition duration, despite equivalent total training volume and similar muscle hypertrophy outcomes.
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.
If new guys do leg exercises with slow reps (6 seconds) instead of faster ones (2 seconds), they might get stronger in a specific knee position—even if they do the same number of sets and their muscles grow the same amount.
See the scientific wording
In untrained males performing knee extension exercises to muscle failure with moderate loads (50–60% 1RM), resistance training with a 6-second repetition duration is associated with greater gains in maximal isometric strength at 30° of knee flexion compared to a 2-second repetition duration, despite similar overall training volume and muscle hypertrophy outcomes.
What the research says
1 studyThe study found that slowing down the exercise movement (6 seconds per rep) helped untrained men gain more strength when their knees were bent slightly, compared to faster reps, even though both groups gained the same amount of muscle.
