The Claim
Many resistance training studies lack sufficient statistical power to detect small but meaningful differences in muscle hypertrophy among trained individuals, resulting in inconclusive or misleading outcomes.
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.
A lot of workout studies don’t have enough participants to notice small but real muscle gains in people who already lift weights, so their results might be confusing or wrong.
See the scientific wording
Many resistance training studies are underpowered to detect small but meaningful differences in hypertrophy among trained individuals, leading to inconclusive or misleading results.
What the research says
1 studyThis study used a lot of people and careful methods to see if two types of weight training make different muscle gains in trained people — and found almost no difference. That proves how hard it is to spot small benefits, which is exactly what the claim says: many studies are too weak to tell if one workout is better than another.
