In the track and field sprinting event, the difference between winning and losing a race is within a fraction of a second. Any slight change in technique during practice can have a drastic effect on race day. Many devices help coaches and sprinters collect data; however, these devices can be expensive or inefficient. The Florida State University Track and Field team uses a phone camera to record the sprinter, and this system is not the most efficient way to analyze their form. Our project provides an inexpensive, easy-to-use training system that offers accurate sprinting data. The system consists of a GoPro Hero8 camera, a tripod, track markers, and an Android app. It measures the sprinters' stride length (the distance between each step) and stride frequency (how quickly a sprinter steps) in the 100m sprint.

The system works by placing markers 1m apart along a 10m portion of the track. The camera is mounted on the tripod where it can capture the 10m portion. The camera records the sprinter as they run by. Afterwards, the camera sends the video to the Android app via Wi-Fi. The app uses image processing techniques to determine stride length and stride frequency, and also includes multiple profiles to store the data for several sprinters.
Our system is convenient for coaches and sprinters to record sprints by providing an easily accessible app that stores the sprinters' statistics. Coaches and sprinters can use this data to determine strengths and weaknesses, modify technique, and improve sprinter performance.
