In young athletes, demands of sports are superimposed on normal growth and maturation. It has been suggested that this causes a temporarily increased vulnerability for injuries. We followed 26 talented soccer players (mean age 11.9±0.84 years) longitudinally for 3 years around their adolescent growth spurt, called Peak Height Velocity, to identify differences in number of traumatic and overuse injuries and days missed due to injuries. Peak Height Velocity was calculated according to the Maturity Offset Protocol. The number of injuries was calculated for each player per year. A repeated measurement analysis showed that athletes had significantly more traumatic injuries in the year of Peak Height Velocity (1.41) than in the year before Peak Height Velocity (0.81). A moderate effect size of 0.42 was found for the difference in number of overuse injuries per player per year before (0.81) and after Peak Height Velocity (1.41), respectively. Finally, a moderate effect size of 0.55 was found for difference between days missed due to injuries before (7.27 days per player per year) and during Peak Height Velocity (15.69 days per player per year). Adolescent growth spurt seems to result in increased vulnerability for traumatic injuries. Afterwards athletes seem to be susceptible to overuse injuries.
在年轻运动员中，运动的要求会叠加在正常的生长和成熟过程之上。有人认为，这会导致受伤的暂时易感性增加。我们对 26 名有天赋的足球运动员（平均年龄 11.9±0.84 岁）进行了为期 3 年的纵向跟踪研究，围绕他们的青少年生长突增期（称为高峰身高速度），以确定创伤性和过度使用性损伤的数量以及因伤缺课的天数的差异。高峰身高速度是根据成熟度偏移协议计算的。每年计算每个运动员的受伤次数。重复测量分析表明，在高峰身高速度年（1.41）运动员遭受的创伤性损伤明显多于高峰身高速度年前（0.81）。每年每名运动员的过度使用性损伤数量差异的中等效应量为 0.42（前为 0.81，后为 1.41）。最后，因伤缺课的天数差异（前为 7.27 天/名运动员/年，后为 15.69 天/名运动员/年）的中等效应量为 0.55。青少年生长突增似乎会导致创伤性损伤的易感性增加。之后，运动员似乎容易受到过度使用性损伤的影响。
