  • 60% of clubs using GPS to manage injuries at training

  • Hamstring strains account for 16% of playing time missed

  • Hamstring recurrence rate of 35%

  • Groin pain occurs second only to hamstring strains

Results

  • Rotations have increased over 250%

  • 70% of AFL teams monitor fatigue

  • 20% of NRL teams monitor fatigue

  • Over all 53% of teams

  • Primary consideration for rotating players in their RSA (Repeated Sprint Ability)

Results

“Where possible we try to eventually build up the rehab player’s workload/intensity to match that of game/main training session” (Club 1),

“Used to monitor fitness capacity of returning player and his workload during rehab phase” (Club 20),

“Must reach game level demands prior to return” (Club 26) and

“Need to meet previous benchmarks before return” (Club 13).
