Study on Factors Influencing Physical Health Based on the SOM Network

摘要

This paper builds a students’ physical health influencing factors analysis model based on the SOM network. First, Analytic Hierarchy Process (AHP) is adopted to confirm the weighted value of various indexes of students’ physical health influencing factors. One fourth ofthe weighted value of various indexes is adopted as the gradient to divide students’ physical health grades and periods, and as the input training samples for the SOM network. Following that, the SOM network after training is analyzed for its sensitivity towards factors influencing physicalhealth. Results suggest that: (1) Duration and intensity of physical exercise is a deciding factor. According to the simulated results, a student with disqualified physical health can recover to a sound state by ensuring the index value of the above deciding factor to be above 0.6. (2) Interms of a student with good physical health, when duration and intensity of his physical exercise is “0”, his physical health will be disqualified. In order to maintain the sound physical health, the index value of duration and intensity of his physical exercise must be above0.3.
