BACKGROUND In obesity, the addition of mass loading of the chest wall by adipose tissue decreases compliance, but its ventilation does not seem to be a limiting factor to physical performance. Plasma K(+) and lactic acid are considered important determinants of ventilation during exercise. Obesity is characterized by insulin resistance. OBJECTIVES The aim(More)
This study aims to describe the changes that a period of low-calorie diet and physical training determines in heart rate and in corrected QT (QTc) interval in obese patients with coronary heart disease (CHD) and to verify whether it is effective in shortening the QT interval using three different methods for QT correction. Two hundred and seventy obese(More)
BACKGROUND AND AIM The effects of combined physical exercise and a hypocaloric diet on left ventricular function in obese subjects without heart disease are not well defined and have never been studied with the tissue Doppler technique. The purpose of our study was to describe the modification of left ventricular systolic and diastolic functions after a(More)
We sought to describe the differences in exercise prescription in obese subjects using attained METs as compared to the subjective perception of the effort using the Borg scale ratings of perceived exertion (Borg RPE). We studied 552 obese patients who underwent an exercise stress test in the setting of a rehabilitation program. Exercise was prescribed at(More)
OBJECTIVE To define an equation that predicts exercise capacity taking into account body mass index (BMI). DESIGN Retrospective analysis and validation study of a multidisciplinary programme aimed at weight loss and physical rehabilitation. SETTING Tertiary referral hospital. PATIENTS AND METHODS 372 consecutive obese participants (249 men) with(More)
Given that many patients referred to cardiac rehabilitation (CR) are obese, diet therapy, exercise training, nutritional and psychological counselling for both obesity and psychological distress should be included as important components in all CR programmes. In this practice-level, observational study we evaluated the short-term within-group effects of a(More)
OBJECTIVE The objective of this paper is to describe the effects of a rehabilitation programme in obese patients affected with chronic ischaemic heart disease; to identify the factors that influence weight loss and improvement in exercise capacity in everyday practice. METHODS AND RESULTS We studied 562 white patients (381 men) who followed a 23.3 +/- 3.9(More)
BACKGROUND AND AIMS Heart rate (HR) response to exercise has not been fully described in the obese. We wanted to study the differences between obese and non-obese patients in HR behavior during an exercise stress test and to determine whether these differences influence exercise capacity. METHODS AND RESULTS We studied 554 patients (318 females) who(More)
BACKGROUND Psychological interventions in cardiac rehabilitation programs appear relevant in as much they significantly contribute to achieve the goals of rehabilitation, to reduce the risk of relapses and to improve patients' adherence to therapy. To this aim, motivational interviewing (MI) has shown promising results in improving motivation to change and(More)
BACKGROUND AND AIM To evaluate whether chronic treatment with beta-blockers influences resting energy expenditure (REE) and weight loss after a period of diet and physical activity in obese hypertensive patients. METHODS AND RESULTS Seventy-eight obese hypertensive patients (24 males and 54 females) aged 53.7 +/- 11.1 years with mean BMI of 42.4 +/- 5.8(More)
