BACKGROUND The primary purpose of the current study was to determine prospective associations of accelerometer-assessed physical activity intensity and sedentary time with health-related quality of life (HRQOL) indicators among survivors of breast cancer. METHODS A total of 358 survivors of breast cancer wore an accelerometer for 7 days at baseline to(More)
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)
BACKGROUND Exercise training has been demonstrated to enhance physical function and to have a protective effect against functional limitations and disability in older adults. PURPOSE The objective of this study was to determine whether the effects of a home-based, DVD-delivered exercise intervention on functional performance and limitations were(More)
The use of multimedia to influence health behaviors offers unique advantages over more traditional center-based programs, however, little is known about the effectiveness of such approaches in improving physical activity levels over time. The purpose of this study was to examine the efficacy of a progressive and age-appropriate, DVD-delivered exercise(More)
BACKGROUND Previous research supports the efficacy of a 6-month DVD-delivered program for enhancing physical activity (PA) in older adults. In the current study, we examined the degree to which intervention-related increases in PA were maintained after a 6-month, no-contact follow-up. METHODS Follow-up assessments of PA via accelerometry and the Godin(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)
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)
PURPOSE Maintaining quality of life (QOL) and physical and mental health status are important outcomes throughout the aging process. Although cross-sectional studies suggest a relationship between global QOL and physical activity, it is unclear whether such a relationship exists as a function of exercise training. METHODS We examined the effects of two(More)
PURPOSE Many breast cancer survivors report cancer and cancer treatment-associated cognitive change. However, very little is known about the relationship between physical activity and subjective memory impairment (SMI) in this population. The purpose of this study is to examine the relationship between physical activity and SMI and longitudinally test a(More)
