ObjectiveTo follow talented soccer players longitudinally and identify differences in traumatic and overuse injuries before, during and after the maximal rate of growth during the adolescent growth spurt, called peak height velocity (PHV).
Results
Method• 26 talented youth soccer players (mean age: 11.9 (±0.84) years), part of the
talent development program of a professional soccer club• Determination of their PHV (Mirwald et al., 2002)• Injury registration (Fuller et al., 2006) for three years around PHV

Table 1. Mean scores (±standard deviations) for traumatic injuries, overuse injuries, and days missed due to injuries in talented soccer players before, during and after peak height velocity.
*p <.05 for difference between acute injuries before and during PHV
Conclusion & Practical implications• The period of PHV seems to result in increased vulnerability for
traumatic injuries and in the period after PHV athletes seem susceptible for overuse injuries.
• Soccer clubs dealing with talented players, should monitor growth of individual players and take precautions (e.g. in terms of biological age-group selections and training intensity) in periods of intensive growth.
