Although regular exercise (e.g., jogging) in paid fitness facilities become popular in Korea, it is reported that 71% of people who signed up for paid fitness facilities gave up exercising in one month due to a lack of motivation [1]. Existing mobile applications (e.g., Nike+) provide joggers with measurements and social features (e.g., competition in the social network) to support their motivation as reported in [2]. Nevertheless, little is still known about design principles for creating mobile applications for regular jogging. To fill in this gap, we aim to answer to the following research questions: 1) what are the principles for designing mobile applications to support joggers' motivations? 2) what is the satisfaction of joggers with the mobile application created by the design principles? To create a mobile application, we used music as intervention because music may reduce the sensation of fatigue and increase the level of mental arousal [3].
