Purpose: This study is designed to investigate the impact of screen-related activities on the hamstring muscle length, reaction time and body mass index. Methods: 67 students were taken to study with no history of acute and chronic diseases of the musculoskeletal system anywhere in the body. The social-demographic characteristics of students, data and communication technologies and daily computer use, daily digital gameplay, daily phone use, daily TV watching and weekly internet use periods were questioned. Also a flat leg lifting test for the hamstring muscle length, Nelson hand reaction test for the reaction time was performed. Results: The study was conducted with 67 students and the average age of these students is 16 ± 1.1. 48,6 per cent of students using the internet for 1-13 hours a week, 33 per cent of students using the internet for 14-41 hours and 66,6 per cent of students using the internet for 42 hours had hamstring shortcomings. According to the body mass index, 64% of students who don’t play every day were normal, while 5 out of 9 students who played less than 1 hour were low and 4 were normal. The body mass index of all students who played 2-3 hours or 4-5 hours of play was found normal. However, 2 out of 3 students playing more than 5 hours of digital gaming have been obese. There is no relationship between the time of student reaction and the time of computer use (p>0,05). The result: As the weekly internet use time increases, the percentage of students who see hamstring shortness has increased. Students who play more than 5 hours a day also have a very high risk of obesity development, and a linear relationship between digital gameplay times and body mass index has been found.
