The Claim

In recreationally active young men, the co-ingestion of 20 grams of dairy protein with 45 grams of carbohydrate following concurrent resistance- and endurance-type exercise does not significantly increase mitochondrial protein synthesis rates over a 6-hour post-exercise period compared to carbohydrate alone, suggesting that adding protein does not acutely enhance mitochondrial repair or biogenesis in this population and context.

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.

How it works
1 study reviewed
In plain English

If young, active guys work out and then drink a shake with carbs and protein, it doesn’t help their muscles repair energy factories any better than just drinking carbs alone—within the first 6 hours after exercise.

See the scientific wording

In recreationally active young men, co-ingesting 20 grams of dairy protein with 45 grams of carbohydrate after concurrent resistance- and endurance-type exercise does not significantly increase mitochondrial protein synthesis rates over 6 hours compared to carbohydrate alone, indicating that protein addition does not acutely enhance mitochondrial repair or biogenesis in this context.

What the research says

  1. Study: Myofibrillar and Mitochondrial Protein Synthesis Rates Do Not Differ in Young Men Following the Ingestion of Carbohydrate with Milk Protein, Whey, or Micellar Casein after Concurrent Resistance- and Endurance-Type Exercise

    The study found that adding protein to carbs after exercise didn’t help the body make more mitochondria (the energy factories in cells) in young active men, even though it did help build muscle. This matches the claim.
