ObjectiveTo evaluate the advancements in cardiopulmonary exercise testing (CPET) among overweight or obese patients.MethodsReviewed the recent studies on clinical trials of CPET in overweight and obese patients, thought about the CPET advantage in obesity, while CPET equipment use for elucidating the principles underlying obesity and using CPET kinematic scheme to explore fat metabolism.ResultsThe exercise program developed by CPET is scientific, sustainable and advantageous. With this trial, we can develop a relatively effective, fast and measurable amount of exercise, on the basis of the exercise test in obese people, CPET can provide scientific and digital motion reducing weight for overweight patients. At the same time, the trial has become widely applied in research into drug and surgical treatments for overweight patients. It is possible to quantify the efficacy of a trial and ultimately assess the merits of CPET.ConclusionCPET is considered as a fundamental criterion for designing motion schemes. Despite limitations of equipment errors and patient endurance, the benefits of CPET in program formulation have been gradually recognized, which made it a promising tool in the field of obesity management.
