Abstract
統合分析已發現對於抑制控制具有中等的正面效果,然過去研究大多針對強度進行探討,較少探討訓練量 (training volume) 對抑制控制之影響,且目前的發現仍不一致。因此,本研究之目的為探討不同訓練量之急性阻力健身運動對抑制控制之影響。本研究招募120位年輕成年人,分為低訓練量組 (LTV)、中訓練量組 (MTV)、高訓練量組 (MTV),以及控制組 (CON),以硬舉、深蹲、臥推,以及划船作為阻力健身運動介入,控制組則進行35分鐘閱讀,並使用叫色測驗於介入前和後測量抑制控制,以反應時間和準確率作為指標,同時測量P3振幅,並在介入前、後以及認知後測前進行血乳酸的採集。結果發現,在叫色測驗反應時間方面,中性情境下,HTV組之反應時間顯著優於控制組;不一致情境下則是HTV組和MTV組之反應時間皆顯著優於控制組,而HTV組和MTV組沒有顯著差異;一致情境則是四組間沒有顯著差異;準確率以及P3振幅方面同樣發現四組間沒有顯著差異。雖然血乳酸在運動組進行運動介入後皆有顯著提升,但並無急性阻力健身運動影響抑制控制之中介效果。本研究發現在中訓練量以及高訓練量之急性阻力健身運動後,抑制控制之表現有顯著提升,而血乳酸並非急性阻力健身運動提升抑制控制之中介因子。本研究拓展ACSM針對一般健康成年人建議之運動處方,在中訓練量 (3組) 以及高訓練量 (4組) 之全身性多關節阻力健身運動有助於提升認知表現,然其背後機制仍須進一部探討,除了結合神經電生理指標外,亦可往藍班核-正腎上腺素系統之方向進行探討。
Meta analysis showed that acute resistance exercise had a positive and moderate affect to inhibitory control. Most of the studies were focus on the variable of intensity, but seldom focus on the training volume. The finding of these studies was inconsistent. So the purpose of this study aim to find the effect of the different training volume of acute resistance exercise on inhibitory control. Ninety six adults (Mage= 22.5, SD= 1.9) was recruited and assigned to low training volume group (LTV), Medium training volume group (MTV), High training volume group (HTV), and control group (CON). Stroop test was access inhibitory control before pre-test, immediately after intervention, and before post-test, and collected lactate at the same time. P3 was also measured during the Stroop test. The ANCOVA for reaction time demonstrated that significant decrease for the HTV and MTV group in the inconsistent condition, but no effect on accuracy and P3. Nevertheless, mediation analysis showed that blood lactate was not a mediator. Our study expanded the benefit of resistance exercise guideline of ACSM for health adults. Future study could investigate the mechanism of resistance exercise to inhibitory control.
