Abstract
Physical activity and screen time influence many adolescent' fitness problems. This research aims to determine the relationship between screen time and physical activity on adolescent students' cardio-respiratory endurance (VO2max). This research used observational analysis with a cross-sectional study involving 70 teenage students at an Information and Network Technology Vocational School consisting of male and female teenage students. The Screen Time of Adolescents (QUEST) questionnaire was used to assess screen time, the physical activity instrument used the Global Physical Activity Questionnaire (GPAQ v2.0) to assess physical activity levels, and the VO2max instrument used the 20-meter Multistage Fitness Test (MFT). The data analysis technique uses the Pearson correlation test and continues with linear regression using the IBM SPSS statistics 25 application. This analysis is used to determine how significant the relationship between variables. Physical activity has a significant relationship with VO2max (p<0.05), while screen time does not have a direct relationship with VO2max (p>0.05). However, research shows that physical activity and screen time influence VO2max in adolescent students (p<0,05). Physical activity is related to Vo2max, while screen time has no relationship. However, screen time and physical activity simultaneously show a significant relationship. This study makes an important contribution to the understanding of the relationship between modern lifestyle and cardio-respiratory fitness.
