Obesity-associated metabolic changes influence resting and peak heart rate in women and men.

Objectives: To study the relationship between obesity and heart rate (HR) in women and men.

Design: We studied 241 overweight and obese subjects without known heart disease. All subjects underwent ergospirometry during maximal exercise testing on treadmill and recording of body composition, electrocardiogram and clinic and ambulatory blood pressure.

Determinants of systolic blood pressure response during exercise in overweight subjects.

Aim: Higher systolic exercise blood pressure (BP) is associated with increased cardiovascular risk in hypertension. We aimed at identifying covariates of systolic exercise BP in overweight subjects.

Methods: 77 subjects with body mass index (BMI) > 27 kg/m(2) and without known heart disease were tested.
