This study aimed to investigate the effects of technological device usage on physical activity levels and body composition among students at Van Yüzüncü Yıl University. The sample consisted of 466 female and 434 male students. Data were collected through the Physical Activity Participation and Motivation questionnaire and daily step counts measured with a pedometer. Body composition was determined using bioelectrical impedance, and body mass index (BMI) was calculated. Statistical analyses included the Mann Whitney U, Kruskal Wallis-H, and Spearman Correlation tests. Findings revealed that 16.4% of students were underweight, 74.2% were normal weight, and 16.4% were overweight. Significant differences were found in physical activity motivation based on time spent watching TV, technological device usage, and TV program preferences. No significant differences in motivation were observed between genders; however, men showed higher motivation for engaging in vigorous physical activities compared to women. In conclusion, prolonged use of technological devices such as computers, televisions, and smartphones is believed to negatively affect physical activity levels and body composition.
