How muscles take in nutrients when resting vs. moving
Insulin and exercise stimulate muscle alpha-aminoisobutyric acid transport by a Na+-K+-ATPase independent pathway.

Muscles use different ways to take in nutrients depending on whether they are resting or being used. At rest, they need a special pump to bring nutrients in. But when insulin is present or during exercise, they switch to a different way that doesn’t need that pump.
No biological mechanisms were identified in this study. This may be an epidemiological, observational, or survey-based study that reports associations rather than proposing causal biological pathways.

Insulin helps your muscles take in more creatine by making blood flow better and boosting a pump-like system in muscle cells, which helps bring in more nutrients.
When muscles are resting, they need a specific cellular pump to bring in a type of nutrient, but when they're active—like during exercise or after insulin kicks in—they use a totally different method that doesn’t rely on that same pump.
Insulin and exercise help muscles take in a type of amino acid even without using the cell's usual sodium-potassium pump, suggesting they use a different route to get nutrients in.
