Study Shows Ultrarunners Exhibit An Increased Risk For Exercise Dependency

Report of a study in Trail Runner about exercise dependency. From the article:

The criteria used to evaluate exercise addiction include Salience, which refers to prioritizing exercise over other obligations; Conflict, which arises between exercise and responsibilities; Mood Modification, using exercise to enhance emotional well-being; Tolerance, requiring more exercise to achieve the same mental benefits; Withdrawal, leading to negative emotions when unable to exercise; and Relapse, returning to excessive exercise after reducing activity.

Interesting. We often have conflicts around our house about the time I spend running and recovering from running. And I definitely use running to help myself stay positive.

What do you guys think?
