The Claim
Expectancy significantly enhances strength training performance in competitive powerlifters independently of pharmacological intervention, demonstrating that psychological factors can have a substantial impact on physical performance outcomes in elite sports contexts.
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.
Just believing you're getting a performance boost — even if you're not taking any real drugs — can actually help competitive powerlifters get stronger, showing that mindset really matters in top-level sports.
See the scientific wording
