Exercise and Muscle Building Study
Resistance‐only and concurrent exercise induce similar myofibrillar protein synthesis rates and associated molecular responses in moderately active men before and after training

Surprising Findings
Concurrent exercise did not compromise myofibrillar protein synthesis rates compared to resistance-only exercise.
Contradicts the common belief that cardio can negate strength gains by interfering with anabolic responses.
Practical Takeaways
Moderately active men can combine cardio and strength training without fearing reduced muscle growth.

When you start lifting weights, your muscles build new protein faster in the first week than they do after 10 weeks, even if you keep training.
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.
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.
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.
