Indirect undergraduate cardiorespiratory-endurance detecting and evaluating method based on progressively increased squat and rise movements

Abstract

The invention discloses an indirect undergraduate cardiorespiratory-endurance detecting and evaluating method based on progressively increased squat and rise movements. The indirect undergraduate cardiorespiratory-endurance detecting and evaluating method comprises the steps that 1, the height and weight of a subject are measured; 2, the subject carries out squat and rise movements with progressively increased burden, the time for each level is represented by T, n squat and rise movements are needed for the first level, then the times of the squat and rise movements for each following level isincreased by m compared with the times of the previous level; 3, the total squat and rise movement times are calculated, and meanwhile the maximum oxygen uptake amount of the subject is measured by utilizing a cardio-pulmonary function remote-sensing instrument; a multielement regression equation is established by utilizing the total squat and rise movement times, the height of the subject, the weight of the subject and the maximum oxygen uptake amount; a least square method is utilized to calculate a regression coefficient of the multielement regression equation; 4, according to the height,weight and total squat and rise movement time of the subject, the multielement regression equation is input, and the maximum oxygen uptake amount of the subject is calculated and serves as a cardiorespiratory-endurance testing result of the subject.

Description

technical field [0001] The invention relates to the field of cardiopulmonary endurance detection methods, in particular to an indirect evaluation method for college students' cardiopulmonary endurance based on incremental squatting exercises. Background technique [0002] There are two ways to measure cardiorespiratory endurance, direct and indirect. Direct measurement is the most accurate, but it requires specific testing equipment such as treadmills or power bicycles. [0003] Most of the existing indirect measurement methods use submaximal loads and do not require specific sports equipment such as treadmills or power bicycles. However, physiological indicators such as blood pressure and heart rate still need to be measured, and it requires the cooperation of multiple people, which cannot be completed by a single person. There are also certain requirements for the test site, and the test method is still not flexible enough. Contents of the invention [0004] In order to...
