Biological Maturity And The Anthropometric Physical And Technical Assessment Of Talent Identified U16 Australian Footballers, Ashley Cripps, Christopher Joyce, Carl Woods, Luke Hopper
Christopher Joyce
This study compared biological maturation, anthropometric, physical and technical skill measures between talent and non-talent identified junior Australian footballers. Players were recruited from the under 16 Western Australian Football League and classified as talent (state representation; n = 25, 15.7 ± 0.3 y) or non-talent identified (non-state representation; n=25, 15.6 ± 0.4 y). Players completed a battery of anthropometric, physical and technical skill assessments. Maturity was estimated using years from peak height velocity calculations. Binary logistic regression was used to identify the variables demonstrating the strongest association with the main effect of ‘status’. A receiver operating characteristic curve was used …

Natural genetic variation contributes towards athletic performance in various strength/power and endurance based sports. To date, no studies have explored the genetic predisposition towards skill and athletic performance in Australian Football (AF) players. The present pilot study recruited 30 sub-elite AF players who completed tests of endurance, power and technical skill. Specific polymorphisms in nine genes were screened, and assessed for a possible influence on athletic and skill traits. Statistical analysis using generalised linear models identified a number of polymorphisms predictive of endurance and technical skill. The angiotensin-converting enzyme (ACE), normally responsible for regulation of body fluid …

Coaches’ Perceptions Of Long-Term Potential Are Biased By Maturational Variation, Ashley Cripps, Luke Hopper, Christopher Joyce
Christopher Joyce
Talent identification and development programs seek to recognise and promote athletes with long-term potential in a particular sport. Coaches involved in these programs are often required to make inclusions or exclusion decisions based on their perceptions of an athlete’s long-term potential. However, biological maturity can influence physical capabilities of adolescent athletes and may bias coaches’ perceptions of long-term potential. This study explored the relationship between coaches’ perceptions of long-term potential and variations in athlete’s biological maturity. Talented adolescent male Australian footballers from nine (n¼264) different teams were recruited to provide basic anthropometric information for estimates of biological maturity. Coaches from …

How Incremented Fatigue Affects Kicking Performance Of Elite Junior Australian Footballers, Christopher Joyce
Christopher Joyce
Introduction & Aims: Australian football (AF) is a dynamic team invasion sport that requires players to possess unique physical and technical performance attributes. However, as the speed of the game increases and the levels of high intensity running increase, so does the effects of fatigue. Research has investigated the effect of fatigue on maximal kicking distance kinematics however, it is yet to investigate the effects of fatigue on functional kicking performance (accuracy and speed).
Methods: Twenty-four participants from the 2015 WAFL U18s competition were tested. The valid AF Kicking (AFK) test was completed three times, with the Yo-Yo Intermittent …
