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.

How it works
1 study reviewed
In plain English

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.

Why this might work

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.

  1. Study: Exofacial Epitope-Specific Antibodies Detect GLUT4 Translocation in Adult Human, Rat, and Mouse Skeletal Muscle.

    Scientists 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.
