The Claim

In recreationally trained men participating in a 12-week progressive resistance training program, free plasma DNA concentrations significantly increase during periods of high training volume and return to baseline levels following a recovery phase, suggesting that plasma DNA levels respond to exercise intensity and may serve as an indicator of physiological stress associated with overtraining.

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.

How it works
1 study reviewed
In plain English

When guys who work out regularly do intense training, their blood DNA levels go up — and go back down when they rest. This might mean DNA levels can show how stressed their bodies are from too much exercise.

See the scientific wording

In recreationally trained men undergoing a 12-week resistance training program with progressively increasing load, free plasma DNA concentrations rise markedly during periods of high training volume and return to baseline after a recovery phase, indicating that plasma DNA levels change in response to exercise intensity and may reflect physiological stress related to overtraining.

What the research says

1 study
  1. Study: Cell-free plasma DNA as a novel marker of aseptic inflammation severity related to exercise overtraining.

    The study found that DNA levels in the blood go up when men do intense weight training and go back to normal after rest, which supports the idea that this could be a sign of physical stress from overtraining.
