功能特定性指導語的神經回饋訓練對額葉中線Theta與高爾夫推桿表現的影響

近期的統合分析顯示傳統的腦波神經回饋訓練 (NFT) 對於改變腦波和改善運動表現的有效性還沒有定論，造成這個結果的一個可能的原因在於口頭指導語。而建立有效的口頭指導語的基本原則在於誘發與目標大腦活動特徵相對應的心智狀態。因此，為了提高腦波NFT訓練方式的有效性，我們在腦波 NFT中提供一種新方法，稱作功能特定性指導語 (function-specific instruction；FSI) 方法。本研究假設單次運用FSI的NFT方法會比傳統的NFT更有效去調節額葉中線Theta (frontal midline theta；FMT) 和促進推桿表現。方法：招募36名年齡36.08±14.08歲，差點14.05±9.43桿的熟練高爾夫選手，並對三組實施連續抽樣：功能特定性指導語組 (FSI；n = 12)，傳統指導語組 (TI；n = 12) 和偽回饋組 (SC；n = 12)。在測試前後，每位參與者執行40次距離3米的推桿，並記錄進洞數量。在NFT介入時，要求參與者在單次期間練習50次。結果顯示FSI組在 NFT後顯著改善推桿表現。此外，FSI組顯著減少FMT功率，而SC組顯著增加FMT功率。這些發現意味著，與傳統指導語相比，功能特定性指導語對熟練高爾夫選手提升持續性注意力和推桿表現更為有效。

A recent meta-analysis showed that so far evidences supporting the effectiveness of EEG neurofeedback training (NFT) protocol in changing EEG and improving sports performance was rather weak and inconclusive. This result may be attributable to methodological limitations such as the verbal instructions. . The basic tenet underpinning an effective verbal instruction is to induce mental states that correspond to targeted brain activity features. Therefore, this study proposed a new approach, namely the function-specific instruction (FSI) approach, to improve the effectiveness of EEG NFT protocol. As such, we hypothesized that a single session of NFT with the FSI approach would be more effective than that of a traditional one in regulating the frontal midline theta (FMT) and improving putting performance. Method: Thirty-six skilled golfers aged 36.08±14.08 years with a handicap 14.05±9.43 were recruited and consecutive sampling method was used to assign these participants into three groups: a function-specific instruction group (FSI; n = 12), a traditional instruction group (TI; n = 12), and a sham control group (SC; n = 12). In the pre-test and post-test, each participant performed 40 putts from a distance of 3m and the numbers of holed putts were recorded. In the NFT intervention, participants were asked to perform 50 trials in a single session. Results showed that the FSI group significantly improved putting performance after NFT. Moreover, the FSI group significantly decreased FMT power, whereas the SC group significantly increased FMT power after NFT. These findings suggested that the function-specific instruction, compared to traditional instruction, is more effective in enhancing sustained attention and putting performance for skilled golfers.
