I am reading the following journal paper and I have come across the following statement:

Overexpression of GSK-3β significantly increases motile mitochondria in a Tau protein-dependent manner. However, GSK-3β does not alter mitochondrial velocity or mitochondrial run length.

I understand what mitochondrial velocity is but I am not sure what exactly is meant by mitochondrial run length. Any insights are appreciated.


Run length means how far the mitochondria move, each time they move.

The article this references is:

"GSK3β Is Involved in the Relief of Mitochondria Pausing in a Tau-Dependent Manner".

This article has a figure showing the distances in micrometers, although I have trouble working out interpreting the error bars on the graph to see if the distances ("run length") are really different.
