A method of assessing cardiopulmonary fitness involves measuring a biosignal of a user performing an activity, measuring an exercise intensity of the activity, determining a parameter based on the biosignal and the exercise intensity, estimating a cardiopulmonary fitness index based on the parameter, and assessing the cardiopulmonary fitness of the user based on the cardiopulmonary fitness index. ## Claims ### Claim 1 A method of assessing cardiopulmonary fitness, the method comprising: measuring a biosignal of a user performing an activity; measuring an exercise intensity of the activity; determining a parameter based on the biosignal and the exercise intensity; estimating a cardiopulmonary fitness index based on the parameter; and assessing the cardiopulmonary fitness of the user based on the cardiopulmonary fitness index. ### Claim 2 (depends on 1) The method of claim 1, wherein the assessing of the cardiopulmonary fitness is performed by a processor. ### Claim 3 (depends on 1) The method of claim 1, wherein the measuring of the biosignal comprises measuring the biosignal in response to a determination that the biosignal reaches a preset threshold. ### Claim 4 (depends on 3) The method of claim 3, wherein the measuring of the exercise intensity comprises measuring the exercise intensity in response to the determination that the biosignal reaches the preset threshold. ### Claim 5 (depends on 1) The method of claim 1, further comprising receiving an exercise perception level of the user, wherein the measuring of the biosignal comprises measuring the biosignal in response to a determination that the exercise perception level reaches a preset standard. ### Claim 6 (depends on 5) The method of claim 5, wherein the measuring of the exercise intensity comprises measuring the exercise intensity in response to a determination that the exercise perception level reaches the preset standard. ### Claim 7 (depends on 1) The method of claim 1, wherein the biosignal of the user comprises at least one of a heart rate, a respiration rate or both. ### Claim 8 (depends on 1) The method of claim 1, wherein the exercise intensity comprises at least one of an exercise speed, an exercise distance, revolutions per minute (RPM) or a combination thereof. ### Claim 9 (depends on 1) The method of claim 1, wherein the determining of the parameter comprises calculating the parameter based on a value obtained by dividing the biosignal by the exercise intensity. ### Claim 10 (depends on 1) The method of claim 1, further comprising: receiving user information, wherein the estimating comprises estimating the cardiopulmonary fitness index based on at least one of the parameter or the user information. ### Claim 11 (depends on 10) The method of claim 10, wherein the user information comprises at least one of a gender, an age, a height, a weight, a waist measurement, a waist-hip ratio, a body mass index, or a physical activity level of the user. ### Claim 12 (depends on 1) The method of claim 1, wherein the cardiopulmonary fitness index of the user comprises at least one of maximal oxygen consumption, a maximal heart rate, a ventilation threshold, a lactate threshold or a combination thereof. ### Claim 13 (depends on 1) The method of claim 1, further comprising: comparing the assessed cardiopulmonary fitness to a preset cardiopulmonary fitness reference value; and providing the user with a result of the comparing. ### Claim 14 (depends on 1) The method of claim 1, further comprising: estimating a metabolic disease risk index of the user based on the assessed cardiopulmonary fitness of the user; and providing the user with a health care prescription based on the metabolic disease risk index of the user. ### Claim 15 (depends on 1) The method of claim 1, further comprising: generating a personalized exercise program for the user based on the assessed cardiopulmonary fitness of the user; and providing the user with the personalized exercise program. ### Claim 16 (depends on 15) The method of claim 15, further comprising receiving preference information of the user, wherein the generating of the personal exercise program comprises: selecting a template from preset exercise program templates based on the preference information; adjusting an exercise intensity and an exercise duration of the selected template based on the assessed cardiopulmonary fitness of the user; and generating the personalized exercise program based on the adjusted exercise intensity and the adjusted exercise duration of the selected template. ### Claim 17 (depends on 1) A non-transitory computer-readable medium storing instructions that, when executed by a processor, cause the processor to perform the method of claim 1. ### Claim 18 An apparatus for assessing cardiopulmonary fitness, the apparatus comprising: a measurer configured to measure a biosignal of a user performing an activity and measure an exercise intensity of the activity; and a processor configured to determine a parameter based on the biosignal and the exercise intensity and assess the cardiopulmonary fitness of the user based on a cardiopulmonary fitness index estimated based on the parameter. ### Claim 19 (depends on 18) The apparatus of claim 18, wherein the processor is configured to determine whether the biosignal reaches a preset threshold, and the measurer is configured to measure the biosignal and the exercise intensity of the activity in response to a determination that the biosignal reaches the preset threshold. ### Claim 20 (depends on 18) The apparatus of claim 18, further comprising: an input device configured to receive an exercise perception level of the user, wherein the processor is configured to determine whether the exercise perception level reaches a preset standard, and the measurer is configured to measure the biosignal and the exercise intensity of the activity in response to a determination that the exercise perception level reaches the preset standard. ### Claim 21 (depends on 18) The apparatus of claim 18, further comprising: a communication interface configured to receive user information, wherein the processor is configured to determine the parameter based on a value obtained by dividing the biosignal by the exercise intensity and estimate the cardiopulmonary fitness index of the user based on at least one of the parameter, the user information or both. ### Claim 22 A method of assessing cardiopulmonary fitness, the method comprising: receiving a biosignal measured by a sensor while a user performing an activity; determining an exercise intensity of the activity; and assessing, by a processor, the cardiopulmonary fitness of the user based on the biosignal and the exercise intensity. ### Claim 23 (depends on 22) The method of claim 22, wherein the assessing of the cardiopulmonary fitness comprises obtaining a value corresponding to the biosignal divided by the exercise intensity. ### Claim 24 (depends on 22) The method of claim 22, wherein the assessing of the cardiopulmonary fitness comprises: calculating a relative heart rate of the user based on the biosignal and the exercise intensity;
