The Claim
Blockade of α2-adrenergic receptors with phentolamine does not enhance exercise-induced lipolysis in subcutaneous abdominal adipose tissue in endurance-trained men, but significantly increases lipolysis in untrained men, indicating attenuation of α2-mediated antilipolytic signaling by endurance training.
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 men who are endurance-trained, blocking a specific receptor (α2-adrenergic) does not increase fat breakdown during exercise in abdominal fat, but it does increase fat breakdown in men who are not trained, suggesting that endurance training reduces the effect of this receptor in limiting fat breakdown.
See the scientific wording
In endurance-trained men, blockade of α2-adrenergic receptors with phentolamine does not enhance exercise-induced lipolysis in subcutaneous abdominal adipose tissue, whereas it significantly increases lipolysis in untrained men, indicating that α2-mediated antilipolytic signaling is attenuated by endurance training.
What the research says
1 studyIn people who train regularly, their bodies stop responding to a signal that normally slows down fat burning during exercise — so blocking that signal with a drug doesn’t change anything. But in people who don’t train, blocking the signal makes them burn more fat.
