The Claim
In healthy, insulin-sensitive young men, 30 minutes of moderate-intensity cycling exercise at 65% VO2 max is associated with a 23% increase in GLUT4 colocalization with the plasma membrane marker dystrophin and depletion of large and small GLUT4 intracellular clusters, as measured by Pearson's correlation coefficient.
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 healthy young men, 30 minutes of moderate cycling at 65% of maximum oxygen uptake is linked to a 23% increase in the positioning of GLUT4 transporters at the muscle cell surface and a reduction in their storage inside the cell.
See the scientific wording
In healthy, insulin-sensitive young men, 30 minutes of moderate-intensity cycling exercise at 65% VO2 max is associated with a 23% increase in GLUT4 colocalization with the plasma membrane marker dystrophin, as measured by Pearson's correlation coefficient, alongside depletion of large and small GLUT4 intracellular clusters, suggesting enhanced glucose transporter mobilization to the muscle cell surface.
When muscles contract during cycling, signals inside the muscle cells trigger stored glucose transporters to move from clusters inside the cell to the outer membrane, where they open channels for glucose to enter the cell.
What the research says
1 studyAfter 30 minutes of cycling, muscle cells in healthy young men moved more glucose transporters to their outer surface, helping them take up sugar from the blood better — and scientists directly saw this happen under a microscope.
