The Claim
Individual responses to resistance training in muscle size and strength are moderately reproducible across repeated training cycles following a detraining period, as evidenced by correlation coefficients of r = 0.697 for vastus lateralis muscle size, r = 0.761 for biceps brachii size, and r = 0.671 for leg press strength, indicating consistent individual response patterns across identical training programs.
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 respond really well (or not so well) to a weight training program, you’ll probably have a similar result if you do the exact same program again after taking a break.
See the scientific wording
Individual responses to resistance training in muscle size and strength are moderately reproducible when the same program is repeated after a detraining period, with correlation coefficients of r = 0.697 for vastus lateralis muscle size, r = 0.761 for biceps brachii size, and r = 0.671 for leg press strength, indicating that people who respond well (or poorly) in one training cycle tend to show similar responses in a subsequent identical cycle.
What the research says
1 studyPeople who gained more muscle or strength the first time they did the workout tended to do the same the second time, and this study found the exact same patterns the claim talks about.
