CHRONOLOGICAL DEVELOPMENT OF FITNESS QUALITIES IN ELITE
AUSTRALIAN RULES FOOTBALLERS
OVERVIEW
• Introduction
• Methods and Approach to Problem
• Results
• Discussion
• Limitations & Recommendations
• Practical Application
INTRODUCTION
Australian Rules football is one of Australia’s most popular sports 844,799 total national participants in 2012
18 teams in the AFL
Around 11% of players currently on the AFL lists originate from either QLD or NSW
Junior AFL Club Academies
with a primary objective to develop a far greater share of local talent by providing clubs with priority access to elite young footballers.
PATHWAY
• No published research exists on the developmental changes in athletes from the age of 12 to 16 years
• Further, the changes in the performance of the fitness assessment tasks of ARF juniors has never been documented between age groups or within a season.
• A lot of research on U16-AFL
INTRODUCTION
This study had 3 major aims,
quantify baseline reference values for commonly used Australian Rules football fitness tests in junior Australia Rules football players between the ages of 12 and 17 years,
attempt to identify peak velocity periods where specific fitness qualities increase, decrease or plateau and
track changes in fitness qualities across a season.
AIMS
METHODS & APPROACH TO PROBLEM
Four periods of testing over the course of the year
Quarterly testing of the following fitness qualities
• Speed – 10m, 20 and 40 m splits
• Vertical jump height – standing and running
• Agility –AFL Agility test
• Endurance – 2km or 3km time trial
• Anthropometric- height and weight
Test were adapted from the National Draft Combine

RECOMMENDATIONS
Rapid changes in growth between
13-14yrs and 15yrs to 16yrs
Height- 12% change (8cm)
Weight- 25% change in less than 12months (13kg)
RECOMMENDATIONS
Increased risk of injury to bones, muscles and tendons
Coordination Drills introduced
Increased need to monitor training load and intensity

LIMITATIONS AND RECOMMENDATIONS
LIMITATIONS
Assumption that other variables are all equal Eg. hand-eye skills, coordination, psychomotor processing.
RECOMMENDATIONS
Future studies test a wider spread of subjects, eg. interstate
Include 3RM bench press in testing as was shown to be a KPI (Keogh, 1999)
Take a closer look at player positions and physiological determinants
