    by Ryousuke Furukado - August 31, 2021

    This study aimed to determine racing esport games’ effects on the physiological and psychological indices using psychological scales and heart rate monitors. The participants were 10 male university students who did not play games diurnally (mean age ± 20.10, SD = 1.10). Participants wore a wristwatch heart rate monitor, and their resting heart rate was measured for 2 min. The duration of the game play was set to 30 min, and their heart rates were continuously measured during play. The changes in the psychological state before and after the game play were then examined using a two-dimensional mood scale-short term. The results showed that the average heart rate significantly increased during gameplay compared to the resting state. As for participants’ psychological state before and after the gameplay, the vitality, pleasure, and arousal levels increased while the stability level decreased. These results indicate that gameplay in the racing genre can induce a lively mood and increase the heart rate.
