The Claim
Nonresponse to resistance training in muscle strength or size is rare and not consistently observed across multiple variables or training periods; true nonresponse, defined as failing to exceed the minimal detectable change in multiple outcomes or cycles, is uncommon, suggesting that nonresponse should not be diagnosed based on a single outcome or training cycle.
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.
Almost everyone benefits from strength training — if someone doesn’t see gains in one area or one round of training, they likely will in another. Real 'non-responders' are super rare.
See the scientific wording
Nonresponse to resistance training in muscle strength or size is uncommon and rarely consistent across multiple variables or training periods, with only one participant failing to exceed the minimal detectable change in both training blocks for a single strength measure, and no individual classified as a nonresponder across more than one variable, suggesting that true nonresponse is rare and should not be diagnosed based on a single outcome or training cycle.
What the research says
1 studyThe study found that almost everyone responded to muscle training when tested twice, and nearly no one failed both times on more than one measure, which supports the idea that people rarely truly don’t respond to training.
