“…No between-group differences were expected for milestones achieved, such as start age in soccer (which was predicted to be around 5 years of age), supervised training in soccer, and age at which participants started playing in an organised league (Ford et al, 2009;Helsen, Starkes, & Hodges, 1998;Ward, Hodges, Starkes, & Williams, 2007). We expected that the average hours per year in soccerspecific practice activities during adolescence (i.e., 13-18 years of age) would be a predictor of superior anticipation and decision making performance across participants (e.g., Ford et al, 2010a;Weissensteiner et al, 2008) and would differentiate skill groups (i.e., greater amounts of this activity will co-occur with higher scores on the test as indicated by group membership). We further expected, based on the findings of Ford et al (2009), that the average number of hours per year spent in soccer-specific play during childhood (i.e., 6-12 years of age) would be a predictor of test performance and would differentiate the skill groups.…”
