The Claim
In obese adults, fractional glucose uptake (K) remains significantly lower than in lean adults after exercise, with a 20–30% residual deficit, due to persistent impairment in glucose transport and phosphorylation (k3) despite improved perfusion.
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.
After exercise, obese adults have a 20–30% lower rate of glucose uptake in muscles compared to lean adults because the cellular mechanisms for moving and processing glucose remain impaired, even though blood flow to the muscle improves.
See the scientific wording
In obese adults, the fractional glucose uptake (K) remains significantly lower than in lean adults even after exercise, with a 20–30% residual deficit, because while perfusion improves, the underlying defect in glucose transport and phosphorylation (k3) persists.
Even after exercise improves blood flow to muscle, muscle cells in obese individuals still cannot take in and use glucose properly because the proteins that pull glucose into the cell and lock it in place do not work as well as they do in lean individuals.
What the research says
1 studyEven after exercise, obese muscles still can't process sugar as well as lean muscles — not because blood flow is low anymore, but because the muscle cells themselves are still bad at grabbing and using sugar.
