RESPOSTAS CARDIORESPIRATÓRIAS DE INDIVIDUOS SEDENTARIOS OBESOS E NÃO OBESOS EM ESTEIRA ERGOMETRICA

Abstract

Introduction: Anthropometric measurements are associated with higher limiting of motor efficiency and the increase of cardiovascular diseases. The aim of this study is to compare the cardiorespiratory fitness of sedentary obese and non obese, and possible limitations during treadmill test. Materials and Methods: The study was performed in 48 sedentary obese and non-obese males, aged 30-50 years. Anthropometric data were collected: body mass, height, and calculated the body mass index (BMI), and all patients underwent cardiopulmonary exercise test on a computerized treadmill for obtaining the following data: VO2La and VO2 max in ml/ kg/min, resting HR, maximum HR (bpm), and blood pressure (BP), systolic (SBP) and diastolic (DBP) in (millimeters of mercury, mmHg) at the beginning and end of the test. Results in relation to blood pressure values were observed between 8 and 20% higher in the obese group, RPP and HR rest showed no significant differences between the groups, VO2max, and HR max Vo2La exhibit significantly lower in the group sedentary obese. Discussion: The implementation of physical activity imposes cardiorespiratory adaptations to the body, through which the physiological and metabolic compensation. A sedentary lifestyle coupled with the high percentage of body fat hinders these adjustments can bring functional repercussions. Conclusion: The group of obese has reduced cardiorespiratory fitness as a function of body mass and may limit their physical performance.
