Method for evaluating sports load in physical exercise of primary and secondary school students based on heart rate data and exercise time

Abstract

The invention relates to a method for evaluating the sports load in physical exercise of primary and secondary school students based on heart rate data and exercise time. The method comprises collecting, transmitting and analyzing exercise heart rates and the exercise time, and evaluating the sports load in physical exercise. According to the method, the exercise heart rates and the exercise time are collected by using a wristwatch type heart rate monitor; the data is transmitted to a server; the time and the heart rates of the physical exercise are analyzed, stored and displayed by using the server, are uploaded to the internet by using wireless connection and are stored on a platform of a website; the website sets different levels of permissions so as to enable an administrator, teachers and the students to see the time, the heart rates and sports load scores of the physical exercise on the website.

Description

technical field [0001] The invention relates to a method for evaluating exercise load of primary and middle school students based on heart rate data and exercise time. Background technique [0002] In recent years, some important indicators of the physical fitness of Chinese teenagers have shown a downward trend, which is worrying. The overall physical fitness of primary and secondary school students in my country is on a downward trend, specifically manifested in the increasing rate of overweight and obesity among primary and secondary school students, with a growth rate of about 10%. In most students' physical training, it is caused by insufficient exercise load. [0003] Currently, pedometers, accelerometers, and heart rate monitors are the main tools for monitoring exercise load. A pedometer is a simple mechanical motion sensor that measures the number of steps taken during walking or running by recording the acceleration and deceleration of the human body moving in the...

Problems solved by technology

The pedometer data is easy to understand, and the wearer can visually see the number of steps recorded by the pedometer. The main disadvantage of the pedometer is that it simply records the number of steps and cannot measure the intensity and duration of physical activity. Or frequency, if it cannot be used to measure physical activities such as weightlifting, swimming, cycling, etc., due to the lack of accurate prediction equations, even if the number of steps can be accurately recorded, energy expenditure cannot be accurately calculated

The disadvantage of the accelerometer is that it is expensive and can only meet the research needs of a small sample size, and it is not feasible to promote it in most primary and secondary schools in China

Because it is placed directly on the chest, its detection accuracy is relatively high and it can also measure heart rate in real time. It is a type of heart rate monitor that is widely used. The disadvantage is that it is inconvenient to wear.

However, there are still shortcomings, that is, the range of exercise heart rate is too wide, and it is not possible to further divide different exercise intensity levels during exercise time, which is not conducive to the evaluation of exercise intensity
