Waist muscle strength assessment method

The present invention relates to a kind of waist muscle strength assessment method, the waist muscle making experimenter is in isometric contraction state, some pieces of waist muscles are carried out myoelectricity measurement, calculate and obtain the frequency of average power descending slope slopeMPF of each piece of tested waist muscle, using the average of the frequency of average power descending slope of each piece of tested waist muscle tolerance as the waist muscle relative strength endurance of experimenter；Described tested waist muscle is symmetrical bilateral muscle, using the difference of the frequency of average power descending slope of symmetrical left and right tested waist muscle with both the ratio of sum as the tolerance of the waist muscle endurance bilateral symmetry of experimenter。The present invention gives waist muscle relative strength endurance and left and right sides symmetric quantitatively evaluating index and concrete method of testing, improve people's attention rate for teenager power of waist, be also beneficial to bow-backed and tiltedly shoulder the discovery early of teenager and correct early。
