Kinetic And Kinematic Effect Of Flag-Carrying On Referee Agility And Sprinting Performance, William Reed

Master's Theses

Within competitive soccer, assistant referees are expected to keep up with the top speed of players on the field, despite being hindered mechanically by a flag held down at their side. This ability to keep up with speed-of-play can determine effectiveness of calls on the field, yet while being tested, referees are not required to replicate the game-like state of flag-carrying. The purpose of this study was to examine kinetic and kinematic effects of flag-carrying within sprinting and change-of-direction performance in assistant referees to better inform training programs and testing protocols. 18 male referees (mean age 32.11 ± 9.08 years) …
