在青少年和高中体育运动中反复的亚震荡头部撞击对发育中的大脑的影响还知之甚少。与生物力学暴露指标相关的新兴神经影像学数据开始证明各种模式之间的关系。这些变化的长期后果尚不清楚。目前可用的文献综述亚震荡头部冲击对青年和高中年龄的男子足球运动员的影响提供了令人信服的证据，这些影响在这些弱势群体的更有针对性的研究。众所周知，脑震荡会引起临床症状，这对青少年和高中运动员来说尤其重要。然而，不引起诊断为脑震荡的重复头部撞击的影响，称为亚震荡性头部撞击，目前尚不清楚。最近的研究发现，在头部反复受到非震荡性撞击后，大脑也会发生类似的变化，这种变化一度被认为是只有在出现临床症状的情况下发生脑震荡才会引起的。同样，许多报告表明，更高的头部撞击暴露与大脑中更大量的结构和/或功能变化有关。考虑到对大脑的类似影响，无论是否有症状，都需要更多的工作来确定亚震荡头部撞击对个体运动员的长期影响，特别是在青年和高中年龄人群中。
The effect of repeated subconcussive head impacts in youth and high school sports on the developing brain is poorly understood. Emerging neuroimaging data correlated with biomechanical exposure metrics are beginning to demonstrate relationships across a variety of modalities. The long-term consequences of these changes are unknown. A review of the currently available literature on the effect of subconcussive head impacts on youth and high school-age male football players provides compelling evidence for more focused studies of these effects in these vulnerable populations. Concussions are known to cause clinical symptoms, which are especially concerning for youth and high school athletes. However, the effects of repeated head impacts that do not cause a diagnosed concussion, known as subconcussive head impacts, are currently unknown. Recent research has identified similar changes in the brain following repeated nonconcussive impacts to the head, once thought to be caused only by the occurrence of concussion with the presence of clinical symptoms. Similarly, many reports suggest that a higher exposure to head impacts is associated with a greater amount of structural and/or functional changes in the brain. Given the similar effects on the brain, with or without symptoms, more work is needed to determine the long-term effects of subconcussive head impacts on individual athletes, particularly in the youth and high school age population.
