The Claim

In male resistance-trained individuals, overtraining characterized by high training volume (14 tons/week) is associated with a 7-fold increase in urinary isoprostanes, a 56% rise in thiobarbituric acid reactive substances (TBARS), and a 73% increase in protein carbonyls, indicating elevated oxidative stress, which may impair athletic performance and has potential implications for monitoring training load.

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.

In plain English

If guys who lift weights train too much — like a whole lot in a week — their bodies might get stressed in a way that could hurt their performance, and scientists can see this stress through certain markers in their body.

  1. Study: Oxidative stress biomarkers responses to physical overtraining: implications for diagnosis.

    The study found that when male athletes train too hard, their bodies show clear signs of stress, just like the claim says, and their performance suffers.
