Resistance exercise was followed by faster responses on cognitive tasks
Researchers randomly assigned adults to moderate resistance exercise or rest, then examined task performance, brain electrical responses and possible physiological explanations.
Based on the published abstract. The full paper may contain additional methods, results and limitations.
The 30-second takeaway
After resistance exercise, participants responded faster on tasks testing inhibitory control and working memory. The abstract also reports faster timing of a brain electrical response during inhibitory control. These laboratory findings do not establish changes in everyday functioning. An exploratory analysis suggested a possible blood-pressure pathway, but did not confirm the mechanism.
This abstract-based account cannot clarify which comparisons the reported effect sizes represent. Session length, persistence of changes and effects on everyday functioning are not reported.
What the study tested
The trial examined inhibitory control and working memory using modified Flanker and N-back tasks. Blood lactate, blood pressure and brain electrical activity were also measured to explore what might accompany changes in task performance.
Why the mechanism remains uncertain
Blood lactate and systolic blood pressure rose after exercise. Exploratory mediation analyses linked systolic pressure with response-time changes on both tasks, suggesting a pathway worth studying without establishing that raising blood pressure would improve cognition.
