A small 3-ounce sensor capable of recording 2,400 data points of movement in just one second being tested and refined by researchers could be key in reducing the number of injuries to racehorses. Researchers used the biometric sensors to track thoroughbreds as they raced and trained at some of the top racetracks in the country. Using collected data, the team was able to identify miniscule stride changes associated with increased risk of injury, allowing intervention before a catastrophic breakdown.
