The Plan
Part 1:
Demands of the Game
Demands of Training
Implications for Hip & Groin
Part 2:
Field Based Conditioning
Load Management & Monitoring
Demands of the Game
2006/07 vs 2012/13
50% Sprint Distance
24-36% High Intensity Running Distance
125-171% Explosive Sprints
Do Sprints Tell the Whole Story?
Short accelerations, which do not reach speeds necessary to qualify as sprints are more important in game-specific situations
8 x Change of direction per minute
(Bloomfield et al., 2007)
3 x more high acc than sprints (>2.5m/s)
(Bradley et al., 2009)
8 x more max acc than sprints (>2.78m/s)
(Varley & Aughey, 2013)

The increase in the number and proportion of sprints in match-play has been proposed as one causative factor for increased injury rates, in particular groin and hamstring strains (Ekstrand, Hägglund, & WaldÊn, 2011)
What are the risk factors that we can effect on the field?
Higher level of play
Decreased hip abduction ROM and total hip rotation ROM
Reduced hip adductor/ abductor strength
Lower levels of sportspecific training
Mismanagement of training volume & intensity
Field Based Strategy Musculoskeletal tolerance to stress
Load Management & Monitoring
A 'warm up' should do more than it says on the tin!
“One part of my job I’ll never learn to love is the warm-up. I hate it with every fibre of my being. It actually disgusts me. It’s nothing but masterbation for the conditioning coaches.’’
