The Claim
Four weeks of cycling training does not change skeletal muscle myostatin mRNA expression in recreationally active adults, with or without daily supplementation of 200 mg of (–)-epicatechin, suggesting no measurable impact on this molecular regulator of muscle growth.
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.
Taking a supplement called epicatechin while doing four weeks of cycling doesn’t seem to change a muscle protein that controls growth — at least in regular gym-goers.
See the scientific wording
Four weeks of cycling training does not alter skeletal muscle myostatin mRNA expression in recreationally active adults, regardless of (–)-epicatechin supplementation at 200 mg/day, indicating no detectable effect on this regulator of muscle growth.
What the research says
1 studyStudy: (–)-Epicatechin Supplementation Inhibits Aerobic Adaptations to Cycling Exercise in Humans
The study looked at whether cycling plus a supplement called (–)-epicatechin changes a muscle protein regulator called myostatin, and found no change — just like the claim says.
