Exercise and adult women’s health Amos Pines
Be fit – be healthy Ways to measure fitness: Ordinary exercise testing Walk test Parameters used to measure the intensity of exercise: • Heart rate • Oxygen consumption (VO2) • Energy expenditure (METs or k/cal spent during a time unit)
Measuring energy expenditure 1 Metabolic Equivalent Task (MET) = calories spent while resting(the individual basal metabolic rate (BMR) is adjusted for body size) The intensity of physical activity is measured by METs per time unit: 2 METs/h means spending twice the calories needed at rest during 1 hour
Exercise improvescardiovascular risk profile • Body mass index • Total, abdominal (subcutaneous and visceral) fat • Waist circumference • Glucose metabolism/insulin resistance • Blood pressure • Lipids • Endothelial function/intima-media thickness IMPROVED
