Stable choline concentrations in the intervention group might indicate a neuroprotective effect of aerobic exercise.

Regular moderate aerobic exercise reduces plasma AEA levels. 2. This reduction was associated with weight loss and improved mood, in particular, reduced anger.

Proc Proc Natl Acad Sci U S A. 2018 Oct;115(41):10487-92. https://doi.org/10.1073/pnas.1805668115 https://doi.org/10.1073/pnas.1805668115...	n=36	Aerobic exercise	Rest	Low	10 min	Acute	Functional connectivity during cognitive task	1. A single 10-min bout of exercise increased functional connectivity between hippocampus DG/CA3 and cortical regions. 2. The magnitude of the enhanced functional connectivity predicted the extent of memory improvement.

The exercise group showed significant improvements in attentional shift. 2. Neuroimaging analysis revealed the significant preservation of bilateral prefrontal volume in the exercise group. 3. The longitudinal changes in attentional shift and memory were positively correlated with the prefrontal volumetric changes.

Increased volume of the left hippocampus, left cornu ammonis and right hippocampus in the intervention group.

Hippocampus. 2015 May;25(5):605-15. https://doi.org/10.1002/hipo.22397 https://doi.org/10.1002/hipo.22397...	n=92	Aerobic exercise (walking)	Not informed	Low to vigorous	10,000 steps/day threshold (pedometer)	Not informed	Hippocampus volume	1. A greater amount, duration, and frequency of total daily walking activity were each associated with larger hippocampus volume among older women, but not men. 2. These relationships were specific to hippocampus volume, compared to the thalamus, used as a control brain region, and remained significant for low-intensity walking activity, independent of moderate to vigorous-intensity activity and self-reported exercise

The effects of multimodal exercise on cognitive and physical functioning and brain-derived neurotrophic factor in older women: a randomised controlled trial. Age Ageing. 2014 Sep;43(5):623-9. https://doi.org/10.1093/ageing/afu010 https://doi.org/10.1093/ageing/afu010...	n=49	Multimodal exercise program (cardiovascular, strength and motor fitness)	Waiting list	Not reported	60 min, 2x/week	16 weeks	BDNF and cognition	1. The exercise program resulted in neurocognitive and physical performance improvements and increased levels of plasma BDNF, in older women, compared with controls. 2. Increases in BDNF levels imply neurogenesis may be a component of the mechanism underpinning the cognitive improvements associated with exercise.

A positive correlation between the degree of fitness improvement and increased BDNF levels was found. 2. A volume decrease of about 2% of the hippocampus was negatively correlated with fitness improvement and increased BDNF levels; and positively correlated with increased TNF-α concentrations. 3. A decrease in glutamate-glutamine levels was observed in the right anterior hippocampus in the exercise group only.

Participants of the aerobic group showed a significantly reduced cortisol response to the MIST, which was inversely related to the previous exercise-induced amylase and cortisol fluctuations. 2. Higher bilateral hippocampus activity and lower prefrontal cortex (PFC) activity was observed in the aerobic group.
