I. Problem of maturation? • Do soccer players grow earlier and faster? • Soccer players: early or late mature? • Physical characteristics in relation to PHV?
Morphological maturation: PHV • Do soccer players grow earlier and faster? average mature late mature early mature
example: Height cm/year age
example: Height cm/year mean age at peak velocity age
Height and weight height weight APHV = 13.8 years
Question 1: Do soccer players grow earlier and faster than their peers? Answer 1: earlier: probably faster: NO !
2. Soccer players: early or late mature? CL=12.0 jaar SL=9.0 jaar Height=143.1 cm CL=12.6 jaar SL=13.5 jaar Height=165.0 cm
10.5 jaar 17.5 jaar
Question 2: Soccer players: early or late mature? Answer 2: on average early mature
example: Standing Broad Jump cm/year age
example: Standing Broad Jump cm/year mean age at peak velocity age

3. Physical characteristics in relation to PHV? Strength and Speed Flexibility Aërobic and anaërobic endurance
II. Talent identification: multidisciplinary Development Selection Detection Identification
Anaërobic endurance: Shuttle Tempo
