The Claim

In healthy young men, a single session of one-legged knee extensor exercise followed by a mixed meal results in approximately 119% greater glucose uptake in the exercised leg compared to the rested leg during the postprandial period, indicating that exercise enhances muscle glucose disposal under physiological hyperglycemic conditions more than previously estimated using euglycemic clamp techniques.

In plain English

After a single session of one-legged knee extension exercise followed by a meal, the exercised leg takes up 119% more glucose from the blood than the resting leg during the hours after eating, demonstrating that exercise increases muscle glucose uptake under normal post-meal blood sugar conditions more than earlier methods suggested.

Why this might work

After exercise, muscle cells are primed to take up more sugar from the blood when a meal raises blood sugar levels. The exercise depletes stored sugar in the muscle, which activates pathways that make the muscle more responsive to insulin. When insulin rises after eating, these pathways strongly signal the muscle to pull sugar into the cell and immediately convert it into stored energy. This keeps the sugar moving through the cell without building up, so the muscle can keep taking in more. In muscles that didn't exercise, sugar enters but gets stuck inside because the cell can't process it fast enough, which slows down further uptake.

  1. Study: Exercise-induced increase in muscle insulin sensitivity in men is amplified when assessed using a meal test

    After one workout, the exercised leg absorbed almost twice as much sugar from a meal as the resting leg, showing exercise makes muscles better at cleaning up blood sugar after eating—better than older tests had shown.
