Embodiment Construction

[0039] This embodiment provides a method for estimating the exercise load level based on cardiogenic signals, including the following steps:

[0040] Step S1, in the "rest-exercise" experiment, screen out individualized exercise load sensitive indicators from ECG, beat-by-beat blood pressure, and photoplethysmography, and establish individualized exercise load-sensitive indicator vectors, specifically including the following steps:

[0041]Step S1.1, "rest-exercise" experiment and physiological data collection. The data collection time is 6 minutes, including a 3-minute rest period and a 3-minute exercise period. The specific experimental process is: sit quietly on the bicycle for 3 minutes, pedal the bicycle for 3 minutes, and the power is set to 100W. ECG, photoplethysmography, and beat-by-beat blood pressure were collected synchronously throughout the experiment. The acquisition equipment of ECG and photoplethysmogram is the non-invasive heart function instrument NCFM deve...

Abstract

The invention discloses a method for estimating an exercise load level based on cardiogenic signals. The method comprises the following steps: firstly, extracting a great number of characteristics from electrocardiogram, beat-to-beat blood pressure and photoelectric plethysmography in a resting-exercise experiment; secondly, screening individual exercise load sensitive indexes from the characteristics to form an individual exercise load sensitive index vector; thirdly, estimating coefficients of an exercise load estimation equation through a numerical computation method according to the individual exercise load sensitive index vector; finally, in an actual exercise state or a non-exercise state, substituting the individual exercise load sensitive index vector screened from the characteristic parameters, obtained by real-time detection and computation, of the electrocardiogram, the beat-to-beat blood pressure and the photoelectric plethysmography into the load estimation equation to estimate an actual exercise load level. According to the technical scheme, the limitation on estimation of the exercise load level through a single independent index is avoided, and the exercise load level is accurately and comprehensively estimated through various cardiogenic signals.

Description

technical field [0001] The present invention relates to the estimation of the exercise load level, in particular to a method for estimating the exercise load level based on cardiogenic signals. Background technique [0002] Exercise load can be divided into two categories: "external load" and "internal load". "External load" represents the intensity and quantity of stimulation imposed by various external factors on the body. It is also called "physical load". For example, the weight of snatch or clean and jerk during weightlifting, and the speed and torque during pedaling are all external loads. "Internal load", also known as "physiological load", refers to the physiological and psychological adaptive changes shown by the body when it bears a certain intensity of external load, and it is the adaptive adjustment of the body's interior to the body's external stimuli. [0003] Exercise load level refers to the intensity of physiological load on the human body during exercise,...
