Visceral obesity is frequently associated with high plasma triglycerides and low plasma high density lipoprotein-cholesterol (HDL-C), and with high plasma concentrations of apolipoprotein B (apoB)-containing lipoproteins. Atherogenic dyslipidemia in these patients may be caused by a combination of overproduction of very low density lipoprotein (VLDL)(More)
OBJECTIVE To determine mechanisms contributing to the altered lipoprotein profile associated with aging and menopause, apolipoprotein B-100 (apoB-100) and apoA-I kinetic behavior was assessed. METHODS AND RESULTS Eight premenopausal (25+/-3 years) and 16 postmenopausal (65+/-6 years) women consumed for 6 weeks a standardized Western diet, at the end of(More)
To maximize the production and detection of training effects in biofeedback-assisted control of peripheral skin temperature, this study incorporated these methodological features: differential feedback between dominant and nondominant hands, monetary incentives, within-subjects manipulation of training direction and multiple-training sessions, graphic-based(More)
This study evaluated the relative effectiveness of two incentive contingencies in learning biofeedback-assisted control of peripheral skin temperature: positive versus positive/negative monetary incentives. Both incentive groups of 10 participated in six sessions, including pre- and posttraining voluntary control sessions, and four intervening sessions with(More)
Chronic disease is endemic within the Australian community. 3.6 million Australians have diabetes or pre-diabetes with the number increasing by 7% each year. Fifty three percent of Australians have one or more chronic diseases. Increasing levels of activity has proved relatively straightforward, especially through workplace physical activity interventions.(More)
The exercise paradox infers that, despite the well-established cardioprotective effects of repeated episodic exercise (training), the risk of acute atherothrombotic events may be transiently increased during and soon after an exercise bout. However, the acute impact of different exercise modalities on platelet function has not previously been addressed. We(More)
The purpose of the present study was to compare the power of three subject variables as predictors of performance in a skin temperature biofeedback task. Data from three related experiments (N = 52) designed to train digital skin temperature increases in four sessions were pooled. Three measures (mean skin temperature, standard deviation and standard error(More)
