Abdominal obesity and low cardiorespiratory fitness (CRF) are associated with insulin resistance in older adults. Exercise is associated with improvement in insulin sensitivity. Whether this association is mediated by change in CRF and/or abdominal obesity is unclear. The current study is a secondary analysis of data from a randomized controlled trial in Kingston, Ontario. Sedentary older adults (60–80 years) (N = 80) who completed the exercise (N = 59) or control (N = 21) conditions for 6 month...

Background: The efficacy of physical activity with a healthful diet to reduce obesity is established; however, little is known about the translation of effective lifestyle strategies for obesity reduction in primary care settings. Methods: We assessed the effectiveness of a 2-year behaviorally based physical activity and diet program implemented entirely within clinical practices to reduce obesity. A total of 490 sedentary, obese adults were randomized to usual care (n=241) or to the behavioral ...

Abstract Exercise reduces obesity and related glucose tolerance, but whether increasing exercise intensity offers additional benefit at fixed exercise amounts is unknown. To determine the separate effects of exercise amount and intensity on abdominal obesity and glucose tolerance. 24-week, single-center, parallel-group trial from 2009 to 2013. (ClinicalTrials.gov: NCT00955071). Kingston, Ontario, Canada. 300 abdominally obese adults. Control (no exercise) (n = 75) or 5 weekly sessions of low-amo...

Although exercise-induced improvement in cardiorespiratory fitness (CRF) and reduction in abdominal obesity are putative mechanisms by which chronic exercise attenuates insulin resistance (1), the independent contribution of each is unknown. We therefore investigated whether improvement in abdominal obesity and/or CRF mediates the effect of exercise on insulin sensitivity in abdominally obese adults. Participants included sedentary, abdominally obese men and women who participated in two previou...

Cardiorespiratory fitness (CRF) is a strong, independent predictor of morbidity and mortality. Although the majority of adults who increase daily physical activity experience an increase in CRF (VO2 peak), about 10-15% of participants do not increase CRF despite participating in a standardized exercise program. In this study we sought to determine whether exercise combined with a healthy diet was associated with a corresponding improvement in cardiometabolic risk factors despite the absence of c...

Abstract Although progress has been made to elucidate the effects of exercise as a strategy for reducing obesity and related cardiometabolic risk factors, the specific exercise exposures required to achieve optimal benefit continue to be the source of considerable uncertainty and debate. Despite the inference of a dose-dependent relationship between exercise and health benefit, absent from the literature are randomized trials that, without alteration in caloric intake, examine the separate effec...

ments and measurements taken with an automated device (BpTRU) predicted results on ambulatory BP monitoring. We assess positive and negative predictive values and overall accuracy. We look at different cut-points for systolic (130, 135 and 140 mmHg) and diastolic (80, 85 and 90 mmHg) BP. Results. A single automated office BP (AOBP) assessment provides superior predictive values and overall accuracy compared to three manual office BP assessments. For systolic BP, the predictive values are <69% fo...
