The Claim
In healthy, insulin-sensitive young men, GLUT4 is predominantly localized in large and small intracellular clusters adjacent to the plasma membrane in the basal state, and these clusters are partially depleted following exercise but not after glucose ingestion.
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 with normal insulin sensitivity, GLUT4 proteins are clustered near the cell membrane when at rest, and these clusters decrease after exercise but remain unchanged after consuming glucose.
See the scientific wording
In healthy, insulin-sensitive young men, GLUT4 is predominantly localized in large and small intracellular clusters adjacent to the plasma membrane in the basal state, and these clusters are partially depleted following exercise but not after glucose ingestion.
When muscles contract during exercise, stored glucose transporters move from clusters near the cell edge to the surface, spreading out and emptying the clusters. When sugar is eaten, insulin signals the cell to bring some transporters closer to the edge, but they stay in clusters and don't fully empty.
What the research says
1 studyAt rest, muscle cells keep glucose transporters in little clusters near the edge, like tools stored near the workbench. Exercise uses up those clusters by moving them to the edge to grab sugar, but drinking sugar water doesn’t do that — the clusters stay put.
