Prediction of Impact in Athletic Activities – A Systematic Approach to Prevent Injury

Overview

Over three million concussions occur in sports in the United States annually. Research shows that anticipatory neck muscle activation and the active response of neck muscles reduces concussion risk. An electronic system with the ability to warn an athlete of impending impact and engage additional safety equipment would be invaluable. To achieve this goal, an electronic circuit was constructed and programmed. It featured an ultrasonic distance sensor which could detect objects advancing toward the body before the collision occurs. In the threat of an impact, the circuit would engage additional protective gear in order to absorb impact force. The system was tested in a simulated football collision with impact speeds up to four meters per second (m/s). These tests proved the accuracy of the programmed circuit, as it predicted a collision correctly every time with impact speeds up to four m/s. In the case of an impact, it also proved the ability to fill a helmet pad with air. Extensive testing in relevant environments is required to validate this system; however, this is an innovative solution to protect an individual in the event of a collision.
