This is literally what is said in TFA:
> Less activity suggests that the brain had become more efficient at semantic-memory processing as a result of the exercise, requiring fewer resources to access the memories.
- maxerickson 7y agoIt's clear in the paper that their result is the other way around, exercise was correlated with higher activation intensity. https://www.cambridge.org/core/services/aop-cambridge-core/content/view/07DE0F919CEFBCE268A95474DFA1BC47/S1355617719000171a.pdf/semantic_memory_activation_after_acute_exercise_in_healthy_older_adults.pdf https://www.cambridge.org/core/services/aop-cambridge-core/c... The activation intensity isn't necessarily a measure of efficiency anyway. There wasn't a difference in blood flow, so energy use would have been similar.
