Why does holding your finger straight for 1 minute and then curling very slowly makes the bones feel “rusty”?
In: Biology
Are you asking why the joints feel like they’re difficult to move?
Clench your fist around an object like a marker for instance and hold it for a minute. It’ll have the same effect.
What’s going on is kind of like muscle fatigue, because it’s not your bones that are, “rusty” feeling rather the muscles and tendons themselves.
