The Claim
GLUT4 glucose transporters translocate from intracellular storage depots to the plasma membrane and T-tubules during muscle contraction, thereby facilitating glucose entry into muscle cells via facilitated diffusion.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
When muscles contract during exercise, special sugar transporters called GLUT4 move from inside the muscle cells to the outer surface, helping sugar get inside to provide energy.

What the research says
1 studyStudy: Exercise, GLUT4, and skeletal muscle glucose uptake.
The study confirms that when muscles contract during exercise, GLUT4 proteins move from storage inside the cell to the cell surface and T-tubules, allowing glucose to enter the muscle cells - exactly as the claim describes.
