A Comparison Of The Physical And Anthropometric Qualities Explanatory Of Talent In The Elite Junior Australian Football Development Pathway.Pdf, Carl Woods, Ashley Cripps, Luke Hopper, Christopher Joyce Jul 2017

A Comparison Of The Physical And Anthropometric Qualities Explanatory Of Talent In The Elite Junior Australian Football Development Pathway.Pdf, Carl Woods, Ashley Cripps, Luke Hopper, Christopher Joyce

Objectives: To compare the physical and anthropometric qualities explanatory of talent at two develop-mental levels in junior Australian football (AF).
Design: Cross-sectional observational. Methods: From a total of 134 juniors, two developmental levels were categorised; U16 (n = 50; 15.6 ± 0.3 y), U18 (n = 84; 17.4 ± 0.5 y). Within these levels, two groups were a priori defined; talent identified (U16; n = 25; 15.7 ± 0.2 y; U18 n = 42; 17.5 ± 0.4 y), non-talent identified (U16; n = 25; 15.6 ± 0.4 y; U18; n = 42; 17.3 ± 0.6 y). Players completed seven physical …

Biological Maturity And The Anthropometric, Physical And Technical Assessment Of Talent Identified U16 Australian Footballers.Pdf, Ashley Cripps, Christopher Joyce, Carl Woods, Luke Hopper Jun 2016

Biological Maturity And The Anthropometric, Physical And Technical Assessment Of Talent Identified U16 Australian Footballers.Pdf, Ashley Cripps, Christopher Joyce, Carl Woods, Luke Hopper

This study compared biological maturation, anthropometric, physical and technical skill measures between talent andnon-talent identified junior Australian footballers. Players were recruited from the under 16 Western Australian Football
League and classified as talent (state representation; n=25, 15.70.3 y) or non-talent identified (non-state representation; n=25, 15.60.4 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 identifythe variables demonstrating the strongest association with the main effect of ‘status’. A receiver operating characteristiccurve was used to assess the level of discrimination provided by the …

Coaches’ Perceptions Of Long-Term Potential Are Biased By Maturational Variation, Ashley Cripps, Luke Hopper, Christopher Joyce Jun 2016

Coaches’ Perceptions Of Long-Term Potential Are Biased By Maturational Variation, Ashley Cripps, Luke Hopper, Christopher Joyce

Ashley Cripps

Talent identification and development programs seek to recognise and promote athletes with long-term potential in aparticular sport. Coaches involved in these programs are often required to make inclusion or exclusion decisions based on their perceptions of an athlete’s long-term potential. However, biological maturity can influence physical capabilities ofadolescent athletes and may bias coaches’ perceptions of long-term potential. This study explored the relationshipbetween coaches’ perceptions of long-term potential and variations in athlete’s biological maturity. Talented adolescent
male Australian footballers (n=264) from nine different teams were recruited to provide basic anthropometric information
for estimates of biological maturity. Coaches from each team were …

Pathway Efficiency And Relative Age In The Australian Football League Talent Pathway, Ashley Cripps, Luke S. Hopper, Christopher Joyce, James Veale May 2016

Pathway Efficiency And Relative Age In The Australian Football League Talent Pathway, Ashley Cripps, Luke S. Hopper, Christopher Joyce, James Veale

Ashley Cripps

Sporting bodies invest substantial resources into the identification and development of talented junior athletes. However, low retention of junior athletes into senior competition has been reported. One mechanism affecting retention may be selections biased by relative age. This study examined the pathway involvement and birth distribution of athletes (n=2519) selected into the Australian Football League Talent Pathway, over six seasons. Only half of athletes selected into professional teams had any involvement in the talent pathway. Birth distributions at every pathway stage were biased towards relatively older athletes, with relatively older athletes more likely to be de-selected as the pathway progressed. …

Inter-Rater Reliability And Validity Of The Australian Football League's Kicking And Handball Tests, Ashley Cripps, Luke S. Hopper, Christopher Joyce May 2016

Inter-Rater Reliability And Validity Of The Australian Football League's Kicking And Handball Tests, Ashley Cripps, Luke S. Hopper, Christopher Joyce

Ashley Cripps

Talent identification tests used at the Australian Football League’s National Draft Combine assess the capacities of athletes to compete at a professional level. Tests created for the National Draft Combine are also commonly used for talent identification and athlete development in development pathways. The skills tests created by the Australian Football League required players to either handball (striking the ball with the hand) or kick to a series of 6 randomly generated targets. Assessors subjectively rate each skill execution giving a 0-5 score for each disposal. This study aimed to investigate the inter-rater reliability and validity of the skills tests …

Maturity, Physical Ability, Technical Skill And Coaches' Perception Of Semi-Elite Adolescent Australian Footballers, A Cripps, L Hopper, C Joyce May 2016

Maturity, Physical Ability, Technical Skill And Coaches' Perception Of Semi-Elite Adolescent Australian Footballers, A Cripps, L Hopper, C Joyce

Ashley Cripps

Purpose: To confirm the effect of maturational differences on anthropometric and physical testing and explore the effect of maturation on technical skill and coaches’ perceptions of skill in adolescent Australian footballers.

Methods: Athletes were recruited from a semi-elite under 16 competition (n = 94, age 15.7 ± 0.3 years) and completed anthropometric, physical, and technical skill tests. Coaches from each team provided subjective ratings of athletes’ technical skills. Maturation groups were derived from years from peak height velocity estimates, with classifications either later, average or earlier maturing.

Results: Effect size comparisons revealed very large to moderate effects between groups for …

Anthropometric, Fitness And Coaches’ Perceptions Of Technical Skill Favour Early Maturing Adolescent Australian Footballers. Poster 1.21.Pdf, Ashley Cripps, Luke Hopper, Christopher Joyce May 2015

Anthropometric, Fitness And Coaches’ Perceptions Of Technical Skill Favour Early Maturing Adolescent Australian Footballers. Poster 1.21.Pdf, Ashley Cripps, Luke Hopper, Christopher Joyce

Ashley Cripps

During mid-adolescence, biological maturity can vary greatly between athletes of similar
chronological ages, resulting in early maturing athlete’s benefiting from greater anthropometric and
fitness characteristics, when compared to their late maturing counterparts. In Australian Football,
advantages associated with early maturation may also result in greater technical and perceived skill
efficiency. The aim of this study was to examine the impact of maturational status on
anthropometric and fitness testing, technical skill efficiency and coaches’ perceptions of skill in
talented adolescent Australian Footballers (n=225, age 15.64 ± 0.29 years). An estimation of years
from peak height velocity (Y-PHV) was used to class …
