The Claim
Moderate aerobic exercise performed for eight weeks at 55% VO2max reduces 8-hydroxydeoxyguanosine (8-OHdG) levels by approximately 20% in middle-aged obese Hispanic women, independent of changes in body fat percentage or visceral adipose tissue.
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.
Eight weeks of moderate aerobic exercise at 55% of maximum oxygen uptake lowers levels of 8-hydroxydeoxyguanosine, a marker of oxidative DNA damage, in middle-aged obese Hispanic women, regardless of changes in body fat or visceral fat.
See the scientific wording
Moderate aerobic exercise for eight weeks at 55% VO2max significantly reduces 8-hydroxydeoxyguanosine (8-OHdG) by approximately 20% in middle-aged obese Hispanic women, indicating a reduction in oxidative DNA damage, independent of changes in body fat percentage or visceral adipose tissue.
When a person does moderate aerobic exercise, their muscles produce small amounts of stress signals that tell the body to build up its natural defenses against damage. These defenses include stronger antioxidant systems that clean up harmful molecules before they can harm DNA. As a result, the amount of damaged DNA in the body drops, even if the person does not lose fat.
What the research says
1 studyThis study found that when middle-aged obese Hispanic women exercised moderately for eight weeks, their body’s signs of DNA damage from stress went down by 20%—even though they didn’t lose belly fat. That means exercise itself helps protect cells, not just by making people thinner.
