The Claim
In trained cyclists, post-exercise carbohydrate-protein supplementation reduces glycogen synthase phosphorylation by 3-fold more than placebo within 45 minutes of recovery, indicating greater activation of glycogen synthase and a stronger signal for muscle glycogen replenishment.
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 trained cyclists, consuming a carbohydrate-protein drink after exercise causes a threefold greater reduction in glycogen synthase phosphorylation compared to a placebo within 45 minutes of recovery, resulting in higher glycogen synthase activity and increased muscle glycogen replenishment.

In trained cyclists, post-exercise carbohydrate-protein supplementation reduces glycogen synthase phosphorylation by 3-fold more than placebo within 45 minutes of recovery, indicating greater activation of glycogen synthase and a stronger signal for muscle glycogen replenishment.
After exercise, consuming sugar and protein raises blood insulin and amino acid levels, which turn on a signaling chain that shuts off a brake on the glycogen-building enzyme. This allows the enzyme to switch on fully and rapidly rebuild muscle glycogen stores.
What the research says
1 studyAfter cycling hard, drinking a sugar-and-protein shake turned on the muscle's glycogen-rebuilding enzyme much more than drinking water, helping muscles recover faster.
