# Intermonitor Variability of Garmin Vivofit(r) Jr. Wristband
## 4 Discussion
With this study knowing that intra-device validity is suitable for PA measurement, apart from the fact that this type of activity monitor is the most plausible for use in terms of health [52], these results represent an essential breakthrough in the employment of PA assessment and promotion in children. The success of physical activity wristbands worldwide is justified by their price. Although there are various studies that utilize different wristbands based on their higher or lower price [16; 53], in the case of the Garmin vivofit jr., in addition to being rated as having a medium price, it is the only one that indicates it is specifically designed for children, thus giving it unique characteristics  
In the current market, fitness activity wristbands designed specifically for children are less common compared to those aimed at adults. Most of the available wristbands are designed to fit the wrists and needs of adults, which may not be suitable or comfortable for young children. It is considered that this is a strength of the present study. Physical activity wristbands for children should be tailored to their unique needs, including wrist size, durability, and ability to interact in an engaging way with the child. Models designed for adults may not meet these requirements, limiting their applicability and effectiveness in the context of a study with young children. This research not only presents established findings but also opens up new avenues for future investigations. It would be intriguing to explore the effects of prolonged use of PA wristbands on children's physical activity behavior and habits over time. Moreover, these wristbands can be used to examine the influence of factors such as weather, social environment, and individual preferences on physical activity behavior. Longitudinal studies may provide valuable insights into the long-term impact of these wristbands on behavior and health. This study's findings have the potential to significantly impact the promotion of children's health and the prevention of lifestyle-related diseases in practical application. For example, schools and educational programs could consider incorporating Garmin Vivofit Jr. wristbands into curricular activities to encourage physical activity among students. In addition, educators can use Garmin Vivofit(r) Jr. wristbands to monitor students' PA levels before and after the implementation of an active recess program or enhanced physical education classes. Parents and caregivers can use physical activity wristbands as a motivational tool to encourage active lifestyle habits in children. For example, they can set goals for daily steps or minutes of physical activity and use the data provided by wristbands to track progress and reward achievement. Garmin Vivofit(r) Jr. wristbands can also be used as part of strategies to limit screen time for children. For example, parents can set time limits for electronic device use and use wristbands to encourage children to participate in alternative physical activities when they reach those limits. In addition to measuring PA, activity wristbands can provide information about sedentary behavior in children, such as time spent sitting or being inactive. This information can prove beneficial for comprehending the sedentary behavior patterns of children and devising strategies to mitigate them, such as incorporating active pauses during study sessions or classwork. This study demonstrates the validity of wristband validation, thereby ensuring the reliability of its utilization. Additionally, healthcare professionals can use these devices as assessment and monitoring tools in clinical settings to manage and prevent health issues related to physical inactivity. Overall, this study provides a solid foundation for future research and highlights the potential of Garmin Vivofit Jr. wristbands as a valuable tool for promoting physical activity and health in the pediatric population.
