The Claim
Resistance training with equal total volume produces similar muscle hypertrophy in previously untrained young women whether performed to muscular failure or stopped short of failure, indicating that muscular fatigue is not a necessary stimulus for muscle growth.
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 previously untrained young women, lifting weights to exhaustion and lifting the same total amount without going to exhaustion result in the same amount of muscle growth, meaning muscle fatigue is not required for muscles to increase in size.
See the scientific wording
Resistance training with equal total volume produces similar muscle hypertrophy whether performed to failure or stopped short of failure in previously untrained young women, indicating that muscular fatigue is not a necessary stimulus for growth.
When muscles are stretched and contracted under load, the force generated pulls on muscle fibers and triggers chemical signals that tell the cells to build more muscle protein. The total amount of pulling over time determines how much muscle grows, not how tired the muscle gets.
What the research says
1 studyWhen women did the same total number of curls, whether they pushed until exhaustion or stopped a few reps short, their muscles grew about the same — as long as they did enough reps overall. It’s the total work that matters, not how tired you get.
