The Claim
Exofacial GLUT4 antibody LM048 detects a 2.8-fold increase in sarcolemmal GLUT4 translocation in human skeletal muscle immediately after 30 minutes of cycling at 65% VO2peak, demonstrating that exercise stimulates GLUT4 movement to the muscle surface in vivo.
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 30 minutes of cycling at 65% of maximum oxygen uptake, human skeletal muscle shows a 2.8-fold increase in GLUT4 protein moving to the cell surface, as measured by the LM048 antibody.

When muscles work during exercise, they use up energy and create a signal that turns on a protein called AMPK. This protein triggers the movement of glucose transporters from inside the muscle cell to its outer surface. These transporters latch onto the cell membrane through a process controlled by another protein that acts like a switch, allowing more glucose to enter the muscle to fuel continued activity.
What the research says
1 studyScientists used a special dye to see glucose transporters in human muscle cells after cycling, and found nearly three times more of them on the cell surface afterward — proving exercise makes these transporters move to the surface to let in more glucose.
