운동 중독

Abstract

Exercise is considered to be both physically and psychologically beneficial to health. However, excessive exercise can become an addictive behaviour and harmful to an individual. Recent animal experiments have suggested the neural mechanism of addiction. Furthermore, imaging studies have revealed functional and morphological changes in the brains of addicted subjects that provide new insight into the mechanisms underlying addiction. The purpose of this review is to introduce quick and easy screening tools which are reliable and valid for exercise addiction, and to explore the candidate mechanism of exercise addiction and the possibility of brain plasticity induced by exercise addiction. If we understand the property of addiction, it can be a basis for developing programs which are preventive and treatable for exercise addiction.
