Lumbar Muscle Strength Evaluation Method

Abstract

The invention relates to a waist muscle strength evaluation method. The waist muscles of a subject are placed in a state of isometric contraction, electromyographic measurements are performed on several waist muscles, and the average power frequency descending slopeMPF of each measured waist muscle is calculated. The mean value of the average power frequency descending slope of each measured lumbar muscle is used as the measure of the relative strength endurance of the lumbar muscles of the test subject; the measured lumbar muscles are bilateral symmetrical muscles, and the symmetrical left and right are The ratio of the difference between the average power frequency descending slope of the lumbar muscles and the sum of the two was measured as a measure of the left-right symmetry of the lumbar muscle endurance of the subject. The present invention provides quantitative evaluation indexes and specific test methods for the relative strength endurance of waist muscles and left and right side symmetry, which improves people's attention to the waist strength of teenagers, and is also conducive to the early detection and early correction of hunchback and sloping shoulders of teenagers .

Description

technical field [0001] The invention relates to a waist muscle strength evaluation method, in particular to an evaluation method suitable for the relative strength endurance of the waist muscles of teenagers and the symmetry of left and right muscle strength endurance. Background technique [0002] Due to the pressure of the entrance examination and the college entrance examination, middle school students spend at least one-third of their day in class and self-study. The waist muscles bear the weight of their upper body with the help of the spine. Due to long-term maintenance of a certain sitting posture, both sides of the spine are required. Muscles have a certain strength and endurance to support the spine, relieve the pressure between the vertebrae of the spine, and ensure the normal growth of the spine. At the same time, the schoolbags of middle school students are getting heavier and heavier, and students have less and less time for physical exercise. Adolescents are i...
