Waist muscle strength evaluation method

A technique of muscle strength and waist, which is applied in the field of evaluation of the relative strength and endurance of the lumbar muscles of adolescents and the symmetry of the strength and endurance of the left and right muscles, can solve the problem of unfavorable adolescent growth and development, the relative strength and endurance of the lumbar muscles of adolescents, and the symmetry of the left and right side of the muscles. enough attention and other issues to achieve the effect of preventing hunchback and sloping shoulders

Problems solved by technology

[0003] At present, there are no effective evaluation methods and indicators suitable for the relative strength endurance and left-right symmetry of the waist muscles of adolescents. As a result, people have not paid enough attention to the relative strength endurance and left-right symmetry of the waist muscles of adolescents, which is very unfavorable for the growth of adolescents. development

Embodiment Construction

[0023] The invention provides a method for evaluating waist muscle strength: make the waist muscles of the subject in the state of isometric contraction, perform electromyographic measurement on several waist muscles, and calculate the average power frequency (MPF) of each measured waist muscle. ) descending slope (that is, slopeMPF), the mean value of the descending slope of the average power frequency of each measured lumbar muscle is used as a measure of the relative strength endurance of the lumbar muscle of the subject.

[0024] The measured lumbar muscles are preferably aimed at one or more bilateral symmetric muscles. When a bilateral muscle is included, the average power frequency of the left and right measured lumbar muscles in this bilateral muscle is reduced by a slope The ratio of the difference between the two and the sum of the two is used as a measure of the left-right symmetry of the subject's lumbar muscle endurance; when multiple bilateral muscles are included...

Abstract

The invention relates to a waist muscle strength evaluation method. The waist muscles of a tested person are in an isometric contraction state, myoelectricity measurement is performed on a plurality of waist muscles to obtain average power frequency descending slope MPF of each measured waist muscle through calculation, and a mean value of the average power frequency descending slopes of the measured waist muscles is used for relative strength endurance measurement of the waist muscles of the tested person. The waist muscles of the tested person are bilaterally symmetrical double-side muscles, and a specific value of a difference value of the average power frequency descending slopes of the left and right measured symmetrical waist muscles to the sum of the average power frequency descending slopes is used for measurement of endurance bilateral symmetry of waist muscles of the tested person. The relative strength endurance measurement of the waist muscles, quantitative evaluation index of the bilateral symmetry and a specific testing method are given, the attention of people to the waist strength of teenagers is improved, and as-soon-as-possible finding and correction of humpback and sloping shoulders of the teenagers are also facilitated.

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...
