摘要
为了解太极拳技能学习早期大脑功能的动态变化特点,本研究共招募29名太极拳零基础被试(19名实验组被试,10名对照组被试),采用多时点纵向追踪设计,借助于功能磁共振成像技术,采集技能学习早期不同时点被试完成运动表象任务时的行为和脑功能数据。结果发现:(1)太极拳技能学习早期,技能水平表现出先慢后快的变化特征,运动表象质量也具有变好的趋势;(2)随着太极拳技能水平的提高,运动表象任务诱发的左侧颞上回和左侧楔前叶的激活显著增强,且同样表现出先慢后快的变化特征;(3)相关检验发现,左侧颞上回和左侧楔前叶的激活与运动表象质量以及太极拳技能水平具有中等程度的相关。研究表明,太极拳技能学习早期,左侧颞上回和左侧楔前叶会伴随着太极拳技能水平的提高而发生改变,太极拳技能学习有助于优化与序列动作学习有关的脑区功能。
Accumulating evidence suggests that regular engagement in physical activity,especially structured physical exercise with complex movement patterns like Tai Chi,is linked to change in brain function as measured by spontaneous and task-evoked neural activities.However,studies on brain function at the early stage of Tai Chi training have yet been conducted despite the fact that understanding changes in neurological activities of motor skill learning at the early stage would facilitate more effective teaching and coaching.To this end,we conducted a longitudinal study in which functional magnetic resonance imaging(fMRI)was used to collect data on brain function and behavioral measures during the early stage of Tai Chi training at multiple time points.Nineteen college students who had no Tai Chi experience were recruited in this study and they were arranged to attend 14-week Tai Chi training program.Of note,Tai Chi training session was recorded in order to evaluate the quality of Tai Chi form and its skill level(conducted by professor specializing in Tai Chi).Outcome measures were conducted at Week 2,Week 8,and Week 14.Meanwhile,10 age-and gender-matched college students were considered as control group and they were asked to maintain their unaltered lifestyle with the same outcome measures being arranged at baseline and Week 14.Siemens 3.0 T MRI scanner was used to synchronously collect data on brain function when participants performed a motor imagery task.Group differences on Tai Chi skill level,temporal congruence,and functional activations were investigated using ANOVA while pearson product-moment correlation was performed to examine relationships between them.Behavioral results showed a learning curve on Tai Chi skill level from slow(Week 2 to Week 8)to fast(after Week 8)as the quality of motor imagery gradually improved.fMRI results showed a similiar pattern of change on brain activities,which changed slowly(Week 2 to Week 8)and increased fastly(after Week 8).Such behavioral changes on skill level were significa
