大量的文献主张运动作为一种成功的干预措施，可以增加积极的影响，同时减少消极的影响和焦虑。关于驱动这些影响的机制的问题仍然没有答案，特别是考虑到理论上的注意力适应可能引起的急性运动。我们调查了运动前和运动后的注意力偏差，以检查可能的注意力解释，可以解释这些报告的影响变化。在对实验室的单独访问中，30名高特质焦虑的参与者在自行车测力计上以70%的心率储备完成了30分钟的运动，或者完成了30分钟的安静休息协议。在每次干预期间，完成了注意力偏差的前测和后测修正点探针评估，以及一系列的自我报告焦虑和情感问卷。计算注意偏差评分和反应时间。运动后的点探测性能没有显着变化的功能，所提出的刺激的情感价。然而，作为假设，积极的影响和反应时间显着改善运动后相比，前和后的休息条件和运动前的条件，这表明运动有利于扩大注意力的范围。这些研究结果的影响和未来的发展方向进行了讨论的背景下，传统和当代理论的性格影响和特定状态的情绪反应。
A large body of literature advocates exercise as a successful intervention for increasing positive affect while also reducing negative affect and anxiety. Questions concerning the mechanisms driving these effects remain unanswered, particularly considering theorized attentional adaptations that may be elicited by acute exercise bouts. We investigated pre- and post-exercise attentional bias to examine possible attentional explanations that may account for these reported changes in affect. On separate visits to the laboratory, 30 high trait anxious participants completed 30min of exercise on a cycle ergometer at 70% of their heart rate reserve, or completed a 30-min quiet rest protocol. During each intervention, pre-test and post-test modified dot-probe assessments of attentional bias were completed, as were a series of self-report anxiety and affect questionnaires. Attentional bias scores and reaction times were calculated. Post-exercise dot probe performance did not vary significantly as a function of the affective valence of presented stimuli. As hypothesized, however, positive affect and reaction time improved significantly following exercise compared with the pre- and post-rest conditions and the pre-exercise condition, suggesting that exercise facilitates a broadening of attentional scope. Implications of these findings and future directions are discussed within the context of traditional and contemporary theories of dispositional affect and state-specific emotional responses.
