Figure 1. Difference in right hippocampal volume with reallocation of MVPA.

Analyses were adjusted for sex, age, intracranial volume, education, body mass index, smoking status, alcohol use, and medication for hypertension, dyslipidemia, and diabetes. The reallocation of MVPA expended the remaining activities equally. Mean composition (%/day): sedentary behaviors = 50.5%, light-intensity physical activity = 44.9%, moderate-to-vigorous physical activity = 4.6%. MVPA, moderate-to-vigorous physical activity.
