The Claim

In moderately active men, concurrent exercise (combining resistance exercise with high-intensity interval exercise in either order) does not compromise myofibrillar protein synthesis rates compared to resistance-only exercise, both before and after 10 weeks of training.

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.

Cause and effect
1 study reviewed
In plain English

For men who exercise regularly, doing both weight training and intense cardio together doesn't slow down muscle building compared to just weight training alone, even after 10 weeks of working out.

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 found that doing both strength and high-intensity cardio together doesn't reduce muscle building compared to just doing strength exercises, both before and after 10 weeks of training.
