The Claim

Objectively measured sedentary time and moderate-to-vigorous physical activity (MVPA) are modestly inversely correlated at the phenotypic level (r = −0.27), with only 13% of this relationship attributable to shared genetic factors and a genetic correlation of −0.31, indicating that sedentary behavior and MVPA are not genetically opposite traits.

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

Just because someone sits a lot doesn’t mean they’re genetically wired to be less active — sitting and moving aren’t exact opposites in our DNA, even though they’re somewhat linked in behavior.

See the scientific wording

Objectively measured sedentary time and moderate-to-vigorous physical activity (MVPA) show a modest inverse phenotypic correlation (r = −0.27), with only 13% of this relationship explained by shared genetic factors and a genetic correlation of −0.31, indicating that sedentary behavior is not simply the opposite of physical activity at the genetic level.

What the research says

1 study
  1. Study: Heritability of objectively assessed and self‐reported sedentary behavior

    The study found that being sedentary and being active are somewhat related, but not perfect opposites, especially in our genes—just like the claim says.
