BACKGROUND/OBJECTIVES: We examined the effects of cardiovascular exercise on verbal fluency using a between-groups design.
METHODS
Within our experimental (i.e., exercise) group, participants performed phonemic and semantic verbal fluency tasks (VFTs) before, during, and after a vigorous 30 min bout of cycling. Participants within our control group also completed these VFTs before, during, and after a non-physical activity. We compared the VFT performance of the experimental (exercise) and control (no-exercise) groups of participants in terms of the characteristics of the words that they produced within the VFTs. In addition, we examined these aspects of VFT performance for each participant group across time within the experiment session.
CONCLUSIONS
From these comparisons, we see that exercise influenced VFT performance. Most notably, participants engaged in exercise changed their VFT performance over time, while control group participants did not. Exercising participants produced more words over the course of their exercise session that contained fewer letters over time and were lower in frequency during and after exercise as compared to before exercise. Additionally, topic switches in the VFTs increased after exercise as compared to before exercise. Participants in the control group did not change their VFT performance over time according to any of these measures. These findings indicate that exercise impacted participants' lexical access and that these VFT performance changes were not due to practice effects.
背景/目的：我们采用组间设计研究了心血管运动对言语流畅性的影响。
方法
在我们的实验组（即运动组）中，参与者在进行30分钟剧烈骑行前、骑行期间和骑行后执行了音素和语义言语流畅性任务（VFT）。我们的对照组参与者也在一项非体力活动前、活动期间和活动后完成了这些VFT。我们根据参与者在VFT中生成的单词的特征，比较了实验组（运动组）和对照组（非运动组）的VFT表现。此外，我们在实验过程中，针对每个参与者组，跨时间检查了VFT表现的这些方面。
结论
通过这些比较，我们发现运动影响了VFT表现。最值得注意的是，参与运动的参与者的VFT表现随时间发生了变化，而对照组参与者则没有。与运动前相比，进行运动的参与者在运动过程中生成了更多单词，这些单词随着时间推移包含的字母更少，且在运动期间和运动后的出现频率更低。此外，与运动前相比，运动后VFT中的话题转换增加。对照组的参与者根据这些指标中的任何一项，其VFT表现均未随时间发生变化。这些发现表明运动影响了参与者的词汇提取，并且这些VFT表现的变化并非由于练习效应。
