Acute Exercise Effects Predict Training Change in Cognition and Connectivity.

ABSTRACT:

Purpose

Previous studies report memory and functional connectivity of memory systems improve acutely after a single aerobic exercise session or with training, suggesting that the acute effects of aerobic exercise may reflect initial changes that adapt over time. In this trial, for the first time, we test the proof-of-concept of whether the acute and training effects of aerobic exercise on working memory and brain network connectivity are related in the same participants.

Methods

Cognitively normal older participants (N = 34) were enrolled in a randomized clinical trial (NCT02453178). Participants completed fMRI resting state and a face working memory N-back task acutely after light- and moderate-intensity exercises and after a 12-wk aerobic training intervention.
