The Claim

Myofibrillar protein synthesis rates and certain molecular responses to exercise are diminished following 10 weeks of training in moderately active men, regardless of exercise modality.

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 10 weeks of working out, men who are already somewhat active don't build muscle as efficiently as before, and their bodies don't respond as strongly to exercise—this happens whether they're doing cardio or weight training.

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 men who exercised for 10 weeks and found that their muscle-building responses got weaker over time, no matter what type of exercise they did, which matches the claim.
