To explore the effects of combat sports on functional network connectivity (FNC) in healthy adolescents.
Resting-state fMRI data were acquired from the combat sports (CS) group (n = 32) and non-athlete healthy control (HC) group (n = 29). Resting-state networks (RSNs) were obtained based on independent component analysis (ICA), and FNC analysis was performed. Then, the intra-network and inter-network connections were compared between the two groups.
Compared with the HC group, the CS group demonstrated increased intra-network FC within the sensorimotor network (SMN), visual network (VIN), and cerebellum network (P < 0.01, FDR correction). Besides, decreased inter-network FC was found in the SMN-VIN, SMN-auditory network, SMN-default mode network, attention network (AN)-VIN, and AN-executive control network connections (P < 0.01, FDR correction).
This study showed a complex relationship between combat sports and FNC in adolescents. The observed FNC patterns in the CS group may reflect training-related brain network optimization, early signs of subclinical brain damage, or preexisting differences. The extensive effects of combat sports on FNC in adolescents could expand our understanding of neuromodulatory mechanisms.
探索搏击运动对健康青少年功能网络连接（FNC）的影响。
从搏击运动（CS）组（n=32）和非运动员健康对照组（HC）（n=29）中获取静息态 fMRI 数据。基于独立成分分析（ICA）获得静息态网络（RSN），并进行 FNC 分析。然后，比较两组之间的内网络和外网络连接。
与 HC 组相比，CS 组在感觉运动网络（SMN）、视觉网络（VIN）和小脑网络（P<0.01，FDR 校正）内的内网络 FC 增加。此外，在 SMN-VIN、SMN-听觉网络、SMN 默认模式网络、注意力网络（AN）-VIN 和 AN-执行控制网络连接中发现了较低的外网络 FC（P<0.01，FDR 校正）。
本研究显示了搏击运动与青少年 FNC 之间的复杂关系。CS 组观察到的 FNC 模式可能反映了与训练相关的大脑网络优化、亚临床脑损伤的早期迹象或预先存在的差异。搏击运动对青少年 FNC 的广泛影响可以扩展我们对神经调节机制的理解。
