ADIDAS AND MAJOR LEAGUE SOCCER ANNOUNCE WORLD'S FIRST SMART SOCCER LEAGUE
adidas micoach Elite System – debuting at the 2012 AT&T MLS All-Star Game – to be integrated across Major League Soccer in 2013
NEW YORK July 19, 2012 – adidas and Major League Soccer today announced that MLS will integrate the adidas micoach Elite System league-wide in 2013, marking the world's first "smart league." The announcement comes ahead of the 2012 AT&T MLS All-Star Game, which is set to be the world's first "smart game" integrating the micoach Elite System.
Beginning in the 2013 season, all 19 MLS clubs will use the data-tracking technology from adidas, providing coaches, trainers and players with real-time performance metrics including heart rate, speed, acceleration, distance, field position and, for the first time, power.
By measuring every move, heartbeat and step and relaying that to a coach on the touch line in less than a second, the technology enables a better understanding of the physical and physiological impact on the team, or any individual, during a game or training session. From analyzing trends to preventing overtraining and risk of injury, the micoach Elite System will help maintain optimum levels of player performance week in, week out throughout the season.
