The difference between securing a medal or not in track races can be as little as a fraction of a second. Therefore, there is absolutely no room for error.
The technological precision behind electronic start systems in races was developed to monitor accurate start times for each racer.
Prior to the 2012 London Olympic Games, new starting blocks were introduced to measure the runners’ reaction times, not by movement but by pressure exerted against the foot pad.
As no human reaction time is feasibly expected to be less than one-tenth of a second, any pressure detected faster than this is recorded as a false start. Before this new technology, the previous model had approximately 5mm of error.
Alongside pressure detectors, lasers, video recording and timers were implemented to eradicate this error.
Performance analysis tools
In 2017, the NBA implemented vision technology that tracks players on the court. This allowed coaches to watch back and evaluate every movement of a player.
