有氧健身已被发现对儿童的大脑和认知健康起着积极的作用。然而，许多与有氧健身相关的神经生物标志物仍然未知。在这里，我们使用扩散张量成像，证明了较高的有氧健身与儿童白色物质微结构的更大估计有关。与较低拟合儿童相比，较高拟合的9岁和10岁儿童在胼胝体、放射冠和上级纵束的切片中表现出更大的各向异性分数（FA）。FA效应的主要特点是有氧健身差异的径向扩散，从而提高了髓鞘形成的估计可能会有所不同，作为一个功能的个体差异，在儿童时期的健身。白色物质结构可能是有氧健身的另一种潜在神经机制，有助于灰质区域之间的有效通信以及区域整合到网络中。
Aerobic fitness has been found to play a positive role in brain and cognitive health of children. Yet, many of the neural biomarkers related to aerobic fitness remain unknown. Here, using diffusion tensor imaging, we demonstrated that higher aerobic fitness was related to greater estimates of white matter microstructure in children. Higher fit 9- and 10-year-old children showed greater fractional anisotropy (FA) in sections of the corpus callosum, corona radiata, and superior longitudinal fasciculus, compared to lower fit children. The FA effects were primarily characterized by aerobic fitness differences in radial diffusivity, thereby raising the possibility that estimates of myelination may vary as a function of individual differences in fitness during childhood. White matter structure may be another potential neural mechanism of aerobic fitness that assists in efficient communication between gray matter regions as well as the integration of regions into networks.
