Abstract

LTAD models suggest boys aged 12-16 years should focus on strength, power, speed, agility, and sport-specific skill development. Consequently, implementing movement quality training interventions with football players around PHV will lessen the effects of adolescent awkwardness. Therefore, the aim of this thesis was to a) Assess the intra- and inter-rater reliability of the AAA and its scoring methods among academy football populations and b) explore the effects of maturation on AMC in academy youth footballers, using the AAA. The participants were part of a Category 1 football academy and aged U12-16 during the 2020-21 season. Each movement of the AAA was completed for a total of five repetitions in frontal and sagittal planes on both left and right leg, which were marked using video footage. In study one the intra-rater reliability, was assessed by the lead researcher assessing 59 participants, with a test-retest conducted after 7 days. To determine the inter-tester reliability of the AAA scores, five other testers scored all participants from the video footage. In study two each movement was scored across three areas using a three-point scale. Each specific area was associated to a numeric value, to objectify the athletes movement competency. Each key area score was summated to produce a single total movement score ranging from 3 to 9. The results from study one showed that the AAA is a reliable assessment tool to be used within English football academies. The inter-rater reliability was 0.975, whereas the intra-rater reliability in this study was substantial (0.714). The results from study two, showed that AAA performance of the Double Lunge, SL RDL and hop and stick improves with biological maturity, thus is most likely due to increases in strength which occur during male adolescence. However, the circa- groups were significantly worse at performing the OH squat.
