Introduction: The use of wearable technological devices has gained relevance in school settings due to their ability to monitor real-time indicators related to physical performance and student health. However, their actual impact requires further scientific validation. Objective: To analyze the impact of wearables and smart wristbands on the monitoring of physical performance and health among students in educational institutions in Milagro, Ecuador. Methodology: A quantitative approach was applied using a quasi-experimental pretest-posttest design with a control group. The sample consisted of 240 students aged 9 to 12, selected through stratified proportional and systematic random sampling in six schools (three public and three private). The experimental group (n=120) used smart wristbands for six weeks, while the control group (n=120) received no intervention. Validated questionnaires, teacher records, and device metrics were used. Statistical analysis included t-tests, ANCOVA, Pearson correlation, and sensitivity analysis. Results: The experimental group showed statistically significant improvements in physical activity, sleep quality, health perception, and motivation compared to the control group. These differences remained after adjusting for covariates such as socioeconomic status and previous physical activity levels. Discussion: Findings align with previous research but should be interpreted cautiously due to the quasi-experimental design. Reactivity to the device may have influenced participant behavior during the intervention. Conclusions: The use of wearables had a positive impact on student well-being. Further studies with longitudinal follow-up and more rigorous experimental designs are recommended to confirm effectiveness and support educational integration.
