Vertical jump is one of the most important basic skills because it widely used in many different sports (e.g. blocking and hitting volleyball, layups jumps shots basketball, heading soccer). Our research examines validity VERT™ (Mayfonk Athletic Company) wearable sensing device, designed to measure height jumped. The VERT quite small measuring 4.98 cm length, 0.79 width 2.18 height. It consists an inertial measurement unit (IMU) 3X gyroscope – accelerometer worn near waist athlete. Real-time data transmitted a smart-phone or tablet via Bluetooth. Recorded includes last jump, best average, amounts. objective following analysis was compare recorded with video using Dartfish™. Fifty children ranging age from 3-12 years old local elementary school Calgary Canada participated study as part broader performance class. trial consisted three for analysis. Results this show that can be accurately assess vertical young long they higher minimum threshold. One limitation device battery life only 30 minutes. However, athletes game situations such Volleyball Basketball. also has potential real-time feedback motivate students improve their jumping performance.
