对自愿运动之前的运动行为过程的研究通常指的是分析准备电位（RP）。为此，数十年的研究使用实验室设置与控制运动相关的行动。此外，最近应用的方法侧重于运动员非运动员的比较，忽略了可能的影响，训练历史上RP。然而，RP之前的真实的运动具体的动作，根据技能的收购仍然有待阐明。因此，熟悉后，16名右撇子男性没有射箭经验的志愿者进行重复的运动具体的动作，即40箭发射在60秒休息在一个15米远的标准目标。连续，同步脑电图和右肢肌电图记录在箭释放服务检测运动发作RP分析不同的皮层运动区。根据达到目标的分数，射箭新手，后验，分为熟练和不熟练的组。EMG结果的平均值显示无显著变化（所有p > 0.05），而RP振幅和起始在组间不同，但在运动区间无差异。与不太熟练的新手相比，熟练的新手在释放箭头之前出现较大的RP幅度（p < 0.05）和较晚的RP发作（p < 0.05）。我们认为，这反映了注意力的定向和更大的努力，伴随着中央神经元的准备状态的体育运动。(C)2017爱思唯尔B.V.保留所有权利。
Research on motor behavioural processes preceding voluntary movements often refers to analysing the readiness potential (RP). For this, decades of studies used laboratory setups with controlled sports-related actions. Further, recent applied approaches focus on athlete non-athlete comparisons, omitting possible effects of training history on RP. However, RP preceding real sport-specific movements in accordance to skill acquisition remains to be elucidated.Therefore, after familiarization 16 right-handed males with no experience in archery volunteered to perform repeated sports-specific movements, i.e. 40 arrow-releasing shots at 60 s rest on a 15 m distant standard target. Continuous, synchronised EEG and right limb EMG recordings during arrow-releasing served to detect movement onsets for RP analyses over distinct cortical motor areas. Based on attained scores on target, archery novices were, a posteriori, subdivided into a skilled and less skilled group. EMG results for mean values revealed no significant changes (all p > 0.05), whereas RP amplitudes and onsets differed between groups but not between motor areas. Arrow-releasing preceded larger RP amplitudes (p < 0.05) and later RP onsets (p < 0.05) in skilled compared to less skilled novices. We suggest this to reflect attentional orienting and greater effort that accompanies central neuronal preparatory states of a sports-specific movement. (C) 2017 Elsevier B.V. All rights reserved.
