Each cell represents the correlation between adult performance level and scores in a test (corrected or uncorrected). For example, the value in the last cell of the first column (r = –.29) represents the correlation between adult performance level and scores in the sprint test corrected according to %RAH. Yo-Yo = Level 1 Yo-Yo intermittent recovery test; %PAH = attained percentage of the predicted adult height; %RAH = attained percentage of the real adult height. — = not needed since the correlation between motor performance test and maturity indicator was not significant in Table 5. Coding of the adult performance level (0 = non-professional, 1 = professional). Measurement units: seconds (sprint, agility, dribbling, passing), centimeters (jumping), meters (Yo-Yo), and points (shooting, juggling). Critical value of Pearson’s r ( = 5%, one-tailed, df = 119): |r
crit| = 0.15. *Motor tasks with reverse coding (the shorter the time needed, the faster and the better).
