Impact of Level-up Element in Development of Exergame for Preventing Prolonged Orthostatic Dysregulation

We developed an exergame to reduce exercise resistance and maintain motivation in adolescents with orthostatic dysregulation (OD). The 2D side-scrolling action game was played on a smartphone and synchronized with leg exercises in lying and sitting positions, which are considered effective in the treatment of OD. Furthermore, we conducted a three-week experiment with nine healthy participants to verify the relationship between the level-up element of the player character in the game and the players’ playing styles, including playing time and frequency.
