Facts & FiguresProfessional football

1990 -2009 Athletic Factors• Increased distances covered in ALL positions.• Increased distances covered at high speed.• Increased speed and power - ( higher intensity.)• Game is played at quicker pace – (ball & player speeds.)• Number of sprints per game in Premiership has doubled since 2002.• Average number of high intensity activities has almost doubled since 2002.

• Change in player body-type to muscular mesomorph.• Higher levels of body strength are now required.• Increased resistance to injury now more apparent.• Diet, nutritional understanding has improved significantly.• Pre – hab sessions now incorporated.• Recovery & regeneration strategies greatly enhanced.• Larger player pools and nationalities / ethnicities.• Increased number and use of substitutes.

Injury prevention screening

Screening intrinsic risk factors

• Functional screening

•Adapted FMS

• Flexibility

• Anthropometric

• Girth measurements

• Functional strength tests

• Physical tests

• Jump tests

1. Screen Intrinsic risk factors

2. Analyse workload

3. Monitor players

Individual risk profile Most susceptible body

zones Develop appropriate

prevention programs

Injury Prediction Algorithm

Individual risk

profile

• Compare 2 or more moments in time

• Injury sensitive zones • Evolution through

adapted program • Quality control
