Wearable technology and biometrical data analysis have been around for a number of years within the Elite sports sector. In the last decade, significant progress has been made in the professional sports market; to the extent that many of the biometrics used by athletes are now available for consumers. The paper will focus primarily on four topics; the extent to which data from the wearable devices can be of benefit to the coaches and athletes; to what extent wearable devices can optimise training; the extent to which wearable technology could prevent injury; and also take a look at what the future holds for elite level wearable technology. Insights gathered include how the data provided by the wearable devices could benefit the health and well-being of an athlete. The data fed back to the coaches and medical staff could enable early detection of an injury and hence training could be adjusted accordingly. Furthermore, the data enables the athlete to monitor themselves and therefore, benchmark themselves against others and identify areas for improvement.
