Abstract

|
|
Purpose: The purpose of this study was to examine the effect of an 8-week competitive exercise program on physical fitness, psychological variables, and video-game playtime in game-addicted adolescents.
Methods: All subjects were screened by a game behavior diagnosis scale questionnaire, and a total of 7 game-addicted, male adolescents (16±2 yrs of age) participated in the study. All subjects were informed of the study’s purpose, procedures, and risks, and a consent form was obtained from each subject. The 8-week soccer and basketball exercise program included twice-weekly sessions of 120 minutes per session. All data were presented as mean±SE, and the variables were analyzed with a paired t-test.
Results: Following the 8-week intervention, cardiovascular endurance and grip strength were significantly increased (approximately 17 and 7%, respectively [p<0.05]). Although there was no statistical significance on flexibility, vertical jump, and zigzag-run, all variables showed an increasing tendency. Anxiety levels changed from a mild anxiety state to a normal state, and depression levels also altered from moderate to a normal state. The video-game playtime was reduced about 20% during weekends and vacation periods.
Conclusion: Given these combined results, 8 weeks of regular participation in competitive exercise (soccer/basketball) may contribute to positive effects on physical fitness, psychological variables, and video-game playtime in computer-game addicted adolescents.
