Background: ApolipoproteinE ε4 carriers (ε4+) have a heightened risk for Alzheimer's disease (AD) and experience accelerated hippocampal volume (HV) loss during older adulthood, which tends to precede cognitive decline. Exercise interventions can increase HV in sedentary older adults, however it's currently unknown how exercise affects HV in sedentary middle-aged adults and if ε4 carrier status moderates this relationship.

Methods: A subset of 44 adults from an ongoing randomized controlled clinical trial (NIH/NIA: R01AG058919) completed baseline (pre), 6-month (mid), and 12-month (post) testing during a one-year exercise intervention (n = 29, 52% ε4+, 5 males, Age = 55.

Gender-specific effects of self-objectification on visuomotor adaptation and learning.

Self-objectification can influence cognitive and motor task performance by causing resources to be reallocated towards monitoring the body. The present study investigated effects of recalling positive or negative body-related experiences on visuomotor adaptation in women and men. Moderating effects of positive and negative affect were also explored.

Exploring the reasons for wanting a peer partner to be physically active among women living with and beyond a cancer diagnosis: a content analysis.

Background: Initiating and maintaining exercise is challenging for women during and post-cancer treatment. Adopting a peer partner model to provide social support to be active may contribute to lasting behaviour change of both partners. Despite this, finding a "like peer" can be challenging.
