The Claim
Individuals who experience greater increases in muscle size and strength during resistance training tend to experience greater losses in these same measures during detraining, with observed negative correlations of r = −0.673 for biceps brachii muscle size and r = −0.488 for leg press strength, indicating an individual-level association between the magnitude of adaptation and deconditioning.
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 you gain more muscle and strength when working out, you might also lose more when you stop — your gains and losses seem to go hand in hand.
See the scientific wording
Individuals who gain more muscle size and strength during resistance training also tend to lose more during detraining, with negative correlations of r = −0.673 for biceps brachii size and r = −0.488 for leg press strength, suggesting that the rate of adaptation and deconditioning are linked within individuals.
What the research says
1 studyPeople who gained the most muscle and strength during training tended to lose the most when they stopped, which is exactly what the study found.
