The Claim

In trained cyclists, post-exercise carbohydrate-protein supplementation has no effect on the baseline phosphorylation status of any measured muscle signaling proteins prior to exercise.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Description
1 study reviewed
In plain English

In trained cyclists, consuming a carbohydrate-protein drink after exercise does not change the baseline activity levels of muscle signaling proteins before the next workout.

See the scientific wording

In trained cyclists, post-exercise carbohydrate-protein supplementation does not alter baseline phosphorylation of any measured muscle signaling proteins prior to exercise, indicating that the supplement’s effects are specific to the post-exercise recovery state and not due to systemic or pre-existing differences.

Why this might work

After exercise, consuming carbohydrates and protein raises blood sugar and amino acid levels, which triggers insulin release. Insulin and amino acids turn on specific muscle signaling proteins that switch on energy storage and protein building processes, but only after exercise has already occurred. Before exercise, these signals remain unchanged regardless of what is consumed.

    The sugar-and-protein drink doesn’t change muscle signals before you ride your bike, but after you finish, it helps your muscles repair and refill energy faster. That means it’s a recovery aid, not a general booster.
