Maximal oxygen uptake testing and evaluating apparatus

The invention relates to a maximal oxygen uptake testing and evaluating apparatus. Maximal oxygen uptake is one of main indexes for evaluating a body strong and healthy degree. According to the existing maximal oxygen uptake testing and evaluating apparatus, bradycardia caused by myocardial dysfunction generated by ATP (adenosine triphosphate) synthesis reduction due to lactic acid accumulation under the endocardium when some people is in a hypoxia state because of individual difference can not be eliminated, and if the maximum oxygen uptake is figured out according to the heart rate at the moment, the numerical value can be remarkably on the high side. In order to reduce errors, an oxyhemoglobin saturation detection device and an oxyhemoglobin saturation and heart rate matching circuit are arranged in the existing maximal oxygen uptake testing and evaluating apparatus. Therefore, the apparatus can be used for achieving the following two effects: the corresponding heart rate when the hypoxia condition occurs
