BACKGROUND: The purpose of this research study is to assess the use of the VERT device with National Collegiate Athletic Association (NCAA) Division II Volleyball players. The VERT is a wearable and portable device that measures multiple variables including workload, jump performance, jump height, frequency, intensity, and impact. Previous research indicates accurate data overall on jump performance which can then be applied to player work loads and injury risk. Additionally, VERT research has shown effectiveness in developing interventions to decreasing injury and increasing vertical jump height among volleyball players. METHODS: NCAA Division II Volleyball players included in this study will use the VERT device for one collegiate volleyball season, including practices and games. A typical season includes between 4-5 practices in a week and 1-3 games per week. Each device will be calibrated and fitted to each player before the season begins, and then the devices will be assessed throughout the course of the season. The VERT will allow participants to practice and play as they normally would to ensure accurate results. Data from the VERT are stored in the MyVERT mobile application to show player loads during practices and games and better evaluate player performance and potential injury risk. Upon completion of the season VERT data will be analyzed using hierarchical linear modeling to review multiple variables. ANTICIPATED RESULTS: Based on previous research, it is anticipated that the research conducted will reveal outside and opposite side hitters have the greatest workload, jump frequency, intensity, and landing impact. More specifically, results from this study will also reveal that opposite side hitters will perform the greatest intensity of jumps and setters will perform the greatest volume of jumps. The VERT will also be able to determine the positions that perform the greatest volume of jumps reaching their maximum vertical height. After gathering the data, this will be beneficial for the future research to implement training programs and better prevent injury risk.
