The Claim
Single-set resistance training performed to muscular failure may be associated with greater improvements in countermovement jump height compared to single-set resistance training performed with two repetitions in reserve, although the observed difference does not reach statistical significance and the practical benefit remains uncertain.
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.
Doing one set of strength training until your muscles are totally tired might help you jump higher than stopping two reps early, but we’re not sure if the difference really matters.
See the scientific wording
Single-set resistance training to failure may be associated with greater improvements in countermovement jump height compared to training with two repetitions in reserve, but the difference lacks clear statistical support, indicating uncertainty about the practical benefit.
When muscles are pushed to their limit, more nerve signals fire faster to the muscle fibers, making them contract harder and faster, which improves how high a person can jump.
What the research says
1 studyThis study found that lifting weights until you can't do another rep might help you jump a little higher than stopping two reps before failure, but the difference was so small that we can't say for sure it matters. So yes, it might help—but we're not certain.
