The Claim
In trained cyclists, post-exercise carbohydrate-protein supplementation enhances the phosphorylation of Akt, mTOR, rpS6, GSK3, and glycogen synthase, indicating a coordinated molecular response that increases signaling for muscle protein synthesis and glycogen storage.
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.
After exercise, consuming a combination of carbohydrates and protein increases molecular signals in trained cyclists that activate muscle repair pathways and replenish energy stores.
See the scientific wording
In trained cyclists, post-exercise carbohydrate-protein supplementation enhances phosphorylation of key signaling proteins involved in both protein synthesis (Akt, mTOR, rpS6) and glycogen storage (GSK3, glycogen synthase), suggesting a coordinated molecular response that may simultaneously support muscle repair and energy replenishment.
After exercise, consuming sugar and protein together causes insulin and amino acids to rise in the blood. Insulin turns on a chain of signals that first shuts off a brake on glycogen production and then turns on the machinery that builds new muscle proteins. The same insulin signal also activates the protein-building machinery, ensuring both energy stores and muscle tissue are repaired at the same time.
What the research says
1 studyAfter cycling hard, cyclists who drank a sugary protein shake had their muscles turn on more of the molecular switches that help rebuild muscle and refill energy stores compared to those who drank plain water. This means the shake helped both repair and recharge the muscles at the same time.
