■长期的技能学习会导致大脑的结构和功能变化。不同的运动可以在不同的大脑区域触发神经可塑性。排球,作为最受欢迎的团队运动之一,在很大程度上依赖于个人能力,如感知和预测,高水平运动员才能脱颖而出。然而,与非运动员相比,有助于排球运动员表现优异的特定大脑机制仍不清楚。
■我们进行了一项研究,招募了十名女子排球运动员和十名普通女大学生,形成运动员和新手团体,分别。全面的行为评估,包括功能运动屏幕和视听反应时间测试,对两组均给予。此外,两组均获得静息状态磁共振成像(MRI)数据.随后,我们进行了深入分析,聚焦于低频波动(ALFF)的振幅,区域同质性(ReHo),以及运动员和新手群体大脑中的功能连接(FC)。
■两组之间的行为数据没有显着差异。然而,与新手组相比,运动员组在视觉皮层内的ALFF和ReHo均表现出显著的增强。此外,视觉皮层和大脑关键区域之间的功能连接,包括左初级感觉皮层,左补充运动皮层,右岛,左颞上回,和左下顶叶小叶,运动员组明显强于新手组。
■这项研究揭示了排球运动员对与视觉有关的各种大脑功能的显着影响,运动,和认知。这表明排球,作为一项基于团队的竞争活动,促进视觉的进步,认知,和运动技能。这些发现为体育人才的早期培养和青少年的全面发展提供了额外的支持。此外,他们提供了预防和治疗运动相关疾病的新观点。

UNASSIGNED: Long-term skill learning can lead to structure and function changes in the brain. Different sports can trigger neuroplasticity in distinct brain regions. Volleyball, as one of the most popular team sports, heavily relies on individual abilities such as perception and prediction for high-level athletes to excel. However, the specific brain mechanisms that contribute to the superior performance of volleyball athletes compared to non-athletes remain unclear.
UNASSIGNED: We conducted a study involving the recruitment of ten female volleyball athletes and ten regular female college students, forming the
athlete and novice groups, respectively. Comprehensive behavioral assessments, including Functional Movement Screen and audio-visual reaction time tests, were administered to both groups. Additionally, resting-state magnetic resonance imaging (MRI) data were acquired for both groups. Subsequently, we conducted in-depth analyses, focusing on the amplitude of low-frequency fluctuations (ALFF), regional homogeneity (ReHo), and functional connectivity (FC) in the brain for both the
athlete and novice groups.
UNASSIGNED: No significant differences were observed in the behavioral data between the two groups. However, the
athlete group exhibited noteworthy enhancements in both the ALFF and ReHo within the visual cortex compared to the novice group. Moreover, the functional connectivity between the visual cortex and key brain regions, including the left primary sensory cortex, left supplementary motor cortex, right insula, left superior temporal gyrus, and left inferior parietal lobule, was notably stronger in the
athlete group than in the novice group.
UNASSIGNED: This study has unveiled the remarkable impact of volleyball athletes on various brain functions related to vision, movement, and cognition. It indicates that volleyball, as a team-based competitive activity, fosters the advancement of visual, cognitive, and motor skills. These findings lend additional support to the early cultivation of sports talents and the comprehensive development of adolescents. Furthermore, they offer fresh perspectives on preventing and treating movement-related disorders.
