Brief summary
Introduction: Cardiopulmonary exercise test (CPET) is a helpful tool for evaluation of aerobic exercise capacity and tolerance for variety of population. The test progression include an incremental stepwise or ramp control protocol to exhaustion There are different methods used in various clinical setting. CPET involves the measurement of respiratory gas exchange i.e. oxygen uptake, carbon dioxide, minute ventilation, other variables while monitoring ECG, blood pressure, pulse oximetry and exertion perceived (Borg Scale) during an incremental test on a cycle-ergo meter or treadmill. This test allow to assess an integrative exercise responses to submaximal and maximal effort. Aim: To compere exercise responses and achieved criteria for maximal exercise testing with different exercise protocol Methods: Healthy volunteers (normal and overweight ) will be recruited to participants in the study. Demographics (age, sex), anthropometric (height, weight, abdominal circumference), will be measured. By using questionnaire, physical activity behavior and motivation toward engage in physical activity will be filled by the participants. Each participants will conducted an exercise test on treadmill (using Modified Bruce Protocol) and cycle ergometer. Quark CPET metabolic cart (Cosmed, Rome, Italy) will be used to collect and analysis gas exchange. 10 minute after the graded exercise test Supra maximal exercise test (SMT) will be done for 2 minutes one stage (treadmill protocol) or 10% at cycle protocol higher than highest load achieved in the incremental test. All exercise parameter done on the different ergometer will be compared
