The Claim
In overweight adults who are habitually physically active, a single bout of moderate aerobic exercise has no additional effect on insulin sensitivity compared to baseline levels.
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 overweight adults who exercise regularly, one session of moderate aerobic exercise does not change their insulin sensitivity.
See the scientific wording
In overweight adults, a single bout of moderate aerobic exercise does not further improve insulin sensitivity in those who already exercise regularly, suggesting a ceiling effect or reduced responsiveness to acute stimuli in habitually active individuals.
In people who exercise regularly, their bodies have already lowered chronic inflammation in fat and muscle tissue, so a single workout doesn't reduce inflammation any further. Without that drop in inflammation, insulin signaling doesn't improve more, and glucose uptake stays the same.
What the research says
1 studyPeople who exercise regularly don’t get a bigger insulin boost from one extra workout because their bodies are already used to it. But people who don’t exercise usually do get a boost from just one session.
