The Claim

In moderately active men, post-exercise changes in proteins indicative of protein synthesis are similar between resistance-only and concurrent exercise groups, while MuRF1 and MAFbx mRNA levels show exercise order-dependent responses.

Source: Resistance‐only and concurrent exercise induce similar myofibrillar protein synthesis rates and associated molecular responses in moderately active men before and after 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.

Description
1 study reviewed
In plain English

After working out, the way muscles build protein is about the same whether you do strength training alone or mix it with cardio, but two specific muscle-related genes react differently depending on which exercise you do first.

See the scientific wording

Post-exercise changes in proteins reflective of protein synthesis are similar between resistance-only and concurrent exercise groups in moderately active men, though MuRF1 and MAFbx mRNA exhibit some exercise order-dependent responses.

What the research says

1 study
  1. Study: Resistance‐only and concurrent exercise induce similar myofibrillar protein synthesis rates and associated molecular responses in moderately active men before and after training

    The study looked at how exercise affects muscle building in active men and found that doing just strength training or mixing it with cardio leads to similar results, but the order of exercises can change some muscle signals, which matches the claim.
