Problems solved by technology

[0004] ①Primitive reaction stage: when the body first comes into contact with high-temperature environment, its thermoregulation system and cardiovascular regulation system cannot perform effective regulation functions, resulting in a rapid rise in body temperature and heart rate, and unstable blood pressure
[0008] 1. A single index can only reflect the physiological or psychological characteristics of a certain aspect of the body, which is one-sided;
[0009] 2. The dimensions of different individual indicators are different and incomparable;
[0010] 3. The results of the same test evaluated by different single indicators may be inconsistent
However, there is no uniform index to reflect the effect of heat acclimatization training under different conditions. The effects of heat acclimatization training on individual indexes of the human body have been studied through experiments, and a comprehensive index combining physiological and psychological parameters has been established to evaluate The effect of heat acclimatization training under different working conditions has become the focus of most scholars' research

Embodiment 1

[0051] Embodiment 1 The construction method of a kind of human body thermal acclimatization training effect evaluation index of the present invention

[0052] (1) Variable selection

[0053] The selection of variables in comprehensive indicators usually follows the following principles: 1. The selected variables can reflect most of the information of the research object; 2. When the experimental conditions change, the variables can change accordingly; 3. Simple and easy to measure, and the scope of application wide. According to the experimental analysis, the physiological variables that can be selected include: heart rate, systolic blood pressure and diastolic blood pressure representing the cardiovascular system, rectal temperature, eardrum temperature, and skin temperature representing the thermoregulatory system; psychological variables include HSSI, thermal sensation, thermal comfort , RPE. However, because systolic blood pressure, diastolic blood pressure, and thermal co...

Embodiment 2

[0107] Embodiment 2 Application of a kind of human body heat acclimatization training effect evaluation index

[0108] In this embodiment, the evaluation index in Embodiment 1 is used to evaluate the effect of heat acclimatization training, as follows:

[0109]The change curves of comprehensive index D value with exercise time before and after heat acclimatization training for five groups of subjects in groups a, b, c, d, and e are shown in the figure below (before training means the first day of the experiment, after training means the 10th day of the experiment sky). It can be seen from the figure that regardless of whether they have undergone heat acclimatization training or not, the D value of the subjects has a relatively large increase within 15 minutes after the start of exercise. As the exercise time prolongs, the increase in D value gradually slows down. , and the increase of D value after the acclimatization training is slower than that before the training.

Abstract

The invention discloses a method for constructing evaluation indexes of human body heat acclimatization training effect. The method includes the steps: selecting five variables, such as heart rate, rectal temperature, eardrum temperature, thermal sensation, and RPE as the analysis factors; normalizing each variable, using SPSS software to carry out factor analysis, and selecting a factor with an initial eigenvalue greater than 1 as a common factor; and finally, performing linear analysis of the comprehensive index grading system. The method for constructing evaluation indexes of human body heat acclimatization training effect reflects the heat acclimatization training effect under different conditions through a unified index, and the method is simple and versatile.

Description

technical field [0001] The invention belongs to the technical field of low-latitude outdoor thermal environment, and relates to a method for constructing an evaluation index of human thermal acclimatization training effect and its application. Background technique [0002] High-temperature environments widely exist in all walks of life. Working in high-temperature environments will cause changes in a series of physiological and psychological parameters such as body temperature, heart rate, thermal sensation, and fatigue, which in turn affect the physical and mental health of workers and work safety. Heat acclimatization refers to the stable changes in some physiological systems of the body due to the action of heat at a certain frequency, which is manifested in the gradual improvement of the body's reflex adjustment function to heat, and various physiological functions reach a new level. In recent years, many scholars at home and abroad have conducted a lot of research on th...
