Running Can Boost Brain Processing

TOKYO (Dispatches) -- Only ten minutes of moderate-intensity running increases local blood flow to the various loci in the bilateral prefrontal cortex -- the part of the brain that plays an important role in controlling mood and executive functions, researchers at the University of Tsukuba report.
The research team used the well-established Stroop Color-Word Test and captured data on hemodynamic changes associated with brain activity while participants were engaged in each task. For example, in one task, incongruent information is shown, i.e., the word red is written in green, and the participant must name the color rather than read out the word. To do so, the brain must process both sets of information and inhibit the extraneous information. The Stroop interference effect was quantified by the difference in response times for this task and those for a simpler version of the task -- stating the names of color swatches.
The results showed that, after ten minutes of moderate-intensity running, there was a significant reduction in Stroop interference effect time. Furthermore, bilateral prefrontal activation had significantly increased during the Stroop task. After running, participants reported being in a better mood. “This was supported by findings of coincident activations in the prefrontal cortical regions involved in mood regulation,” first author Chorphaka Damrongthai adds.
