OBJECTIVES To examine the relationship between performance on executive function measures and subsequent mobility outcomes in community-dwelling older adults. DESIGN Randomized controlled clinical trial. SETTING Champaign-Urbana, Illinois. PARTICIPANTS Community-dwelling older adults (N = 179; mean age 66.4). INTERVENTION A 12-month exercise trial(More)
Greater physical activity and cardiorespiratory fitness are associated with reduced age-related cognitive decline and lower risk for dementia. However, significant gaps remain in the understanding of how physical activity and fitness protect the brain from adverse effects of brain aging. The primary goal of the current study was to empirically evaluate the(More)
OBJECTIVES To examine whether 12 months of aerobic training (AT) moderated the relationship between change in mobility and change in basal ganglia volume than balance and toning (BAT) exercises in older adults. DESIGN Secondary analysis of a randomized controlled trial. SETTING Champaign-Urbana, Illinois. PARTICIPANTS Community-dwelling older adults(More)
White matter structure declines with advancing age and has been associated with a decline in memory and executive processes in older adulthood. Yet, recent research suggests that higher physical activity and fitness levels may be associated with less white matter degeneration in late life, although the tract-specificity of this relationship is not well(More)
Increased survival rates among breast cancer patients have drawn significant attention to consequences of both the presence of cancer, and the subsequent treatment-related impact on the brain. The incidence of breast cancer and the effects of treatment often result in alterations in the microstructure of white matter and impaired cognitive functioning.(More)
BACKGROUND This study examined the effects of cardiorespiratory fitness, heart rate recovery, and physical activity on working memory in breast cancer survivors and age-matched controls. METHOD Using a case-control design, 32 women who had received a breast cancer diagnosis and completed primary treatment within the past 36-months (11 radiation only; 21(More)
Emerging evidence indicates increased sedentary behavior is associated with poorer health outcomes and quality of life among cancer survivors. However, very little is known about which factors are associated with increased sedentary behavior. The purpose of the present study was to examine potential correlates of sedentary behavior among breast cancer(More)
As breast cancer treatment is associated with declines in brain and cognitive health, it is important to identify strategies to enhance the cognitive vitality of cancer survivors. In particular, the hippocampus is known to play an important role in brain and memory declines following cancer treatment. The hippocampus is also known for its plasticity and(More)
BACKGROUND Well-being is important to healthy aging. The present study examined the trajectories and determinants of well-being in older women (n = 248) over a 39-month period. METHODS Participants completed measures of optimism, pessimism, functional limitations, physical activity, and self-efficacy. Well-being, operationalised as life satisfaction, was(More)
