Increased serum levels of inflammatory mediators have been associated with numerous disease states including atherosclerosis, Type II diabetes, hypertension, depression, and overall mortality. We hypothesized that a long-term exercise intervention among older adults would reduce serum inflammatory cytokines, and this reduction would be mediated, in part, by(More)
BACKGROUND This study investigated the hypothesis that expressions of maximal and submaximal bilateral indices would not differ between older and young participants. METHODS Twenty older (73.3 +/- 4.4 years) and 21 younger (22.4 +/- 0.9 years) participants performed maximal voluntary isometric contractions of the elbow flexor muscles, using the right arm(More)
This study investigated how perceived stress, social support, and home-based physical activity affected older adults' fatigue, loneliness, and depression. We also explored whether social support and physical activity mediated the relationships between stress and mental health problems. The data of 163 older participants were analyzed in this study.(More)
BACKGROUND/OBJECTIVES Objective and subjective measurement instruments have been used to estimate energy expenditure (EE) as alternatives to the doubly labeled water (DLW) methodology, but their relative validity for older adults remains uncertain. The purpose of this study was to validate an objective monitor (SenseWear Mini Armband) and a self-report(More)
INTRODUCTION This study evaluates whether a health club membership is associated with meeting the US physical activity (PA) guidelines and/or favorable cardiovascular health. METHODS Using cross-sectional data of health club members (n = 204) and non-members (n = 201) from April to August 2013, this is the first study to our knowledge to examine a health(More)
BACKGROUND The purpose of this study was to compare the effects of high and low velocity knee extension training on changes in muscle strength and mobility status in high-functioning older adults. METHODS Twenty-six (16 female, 10 male) older adults (mean age of 65) were randomized to either 6weeks of low velocity resistance training (LVRT) performed at(More)
Technology has become an increasingly integral part of life. For example, technology allows individuals to stay in touch with loved ones, obtain medical services through telehealthcare, and enjoy an overall higher quality of life. Particularly for older adults, using technology increases the likelihood that they will maintain their independence and(More)
The primary objective of the Iowa Centenarian Study is to further our understanding of determinants of exceptional longevity above and beyond health outcomes, particularly in rural environments. This introductory article provides a general overview of the study, its methodology and basic descriptive results. One hundred and fifty-two centenarians from a(More)
The 6-min walk test (6MWT) is a common component of fitness assessments of older adults; however, differing course configurations might affect 6MWT performance. It is unclear how comparable 2 different configurations are. To determine the comparability of 2 courses, 35 adults >65 years of age completed two 6MWT, once walking around a 20- by 5-yd outdoor(More)
