Voss MW, Weng TB, Narayana-Kumanan K, et al. – In this study involving 34 cognitively normal older participants, for the first time, researchers tested 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. Participants underwent fMRI resting state and a face working memory N-back task acutely after light and moderate intensity exercise and after a 12-week aerobic training intervention. Overall, the researchers’ findings supported the idea of acute aerobic exercise impact on functional brain systems and performance as an activity-evoked biomarker for exercise training benefits in the same outcomes. They noted that their findings may lead to new insights and methods for improving memory outcomes with aerobic exercise training.
