Brief summary

This study aims to identify and compare the effects of acute and chronic exercise interventions on cognition in middle-aged adults with cognitive complaints and a history of abuse or neglect in childhood. Each participant will be enrolled in the study for up to 78 days, in five parts following verification that the participant meets criteria to be included in the study: 1) initial assessment; 2) first acute exercise condition in lab, symptom measures, and neuropsychological testing; 3) second acute exercise condition in lab, symptom measures, and neuropsychological testing; and 4) 9-week exercise intervention or activity as usual outside of lab, with interview, symptom measures, and neuropsychological testing at three-week intervals.

Interventions

BEHAVIORALModerate Intensity Exercise (one day)

Participants will engage in 40 minutes of cycling at 70-75% maximum heart rate (MHR).

BEHAVIORALPlacebo - Light Intensity Exercise (one day)

Control participants will engage in 40 minutes cycling at 40-50% maximum heart rate (MHR).

BEHAVIORALModerate Intensity Exercise (9 wks)

Participants will be asked to engage in moderate-intensity activity four days each week, 40 minutes each time, and will wear an activity monitoring device to assess their fidelity to the intervention.
