The Claim
A one-week complete cessation of resistance training at the midpoint of a 9-week high-volume program reduces lower body isometric and dynamic strength gains in young, resistance-trained adults compared to continuous training, with posterior probabilities of 0.924 and 0.851 favoring continuous training, respectively.
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 young adults who regularly lift weights, stopping all resistance training for one week halfway through a 9-week program results in smaller increases in lower body strength compared to those who train continuously.
See the scientific wording
A one-week complete cessation of resistance training at the midpoint of a 9-week high-volume program reduces lower body isometric and dynamic strength gains in young, resistance-trained adults compared to continuous training, with posterior probabilities of 0.924 and 0.851 favoring continuous training, respectively, suggesting a small but probable negative effect on strength adaptation.
When training stops, muscle cells stop receiving the signal to build more contractile proteins, so muscle fibers lose their ability to generate force as quickly as they would if training continued.
What the research says
1 studyTaking a one-week break from leg workouts halfway through a nine-week training program led to slightly smaller gains in leg strength compared to training without stopping, according to this study.
