Problems solved by technology

The current model that uses a single heart rate index to estimate the level of exercise load cannot fully reflect the response of the cardiovascular system to exercise load, and has the disadvantages of singleness and one-sidedness

Embodiment Construction

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

[0040] Step S1. In the "rest-exercise" experiment, select individualized exercise load sensitivity indicators from ECG, beat-by-beat blood pressure, and photoelectric volume wave, and establish an individualized exercise load sensitivity index vector, which specifically includes 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 resting period and a 3-minute exercise period. The specific experimental process is: sitting quietly on the bicycle for 3 minutes, pedaling the bicycle for 3 minutes, and the power is set to 100W. ECG, photoelectric volume wave, and beat-by-beat blood pressure were collected simultaneously throughout the experiment. The collection equipment of electrocardiogram and photoplethysmography is the non-invasive card...

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 exercise load level, in particular to a method for estimating exercise load level based on cardiogenic signals. Background technique [0002] Exercise load can be divided into "external load" and "internal load". "External load" characterizes the intensity and amount of stimulation applied to the body by various factors outside the body, also known as "physical load", refers to the amount of exercise or work done by the body in a unit time, generally in terms of distance, speed, and quality , Time and number of exercises, etc., for example, the weight of snatch or clean and jerk during weight lifting, 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 that the body exhibits when it bears a certain intensity of external load. It is the body's internal adaptive adjustment to the body'...
