1. A method for evaluating shock absorption effect of a sports bra, comprising:
marking at least four data acquisition points on a subject, the at least four marked data acquisition points comprising a data acquisition point located proximate to each of a cervical vertebra, a thoracic vertebra, a sternal angle, and a breast of the subject, wherein the data acquisition point located proximate to a thoracic vertebra and the data acquisition point located proximate to a sternal angle are located at a same vertical height of the subject;
acquiring static coordinate data from the at least four marked data acquisition points of the subject while the subject is wearing the sports bra and naturally standing on a treadmill, the static coordinate data acquired using a data acquirer configured to track the position of the at least four marked data acquisition points of the subject and communicate with a data processor configured to process data acquired by the data acquirer;
starting the treadmill and acquiring dynamic coordinate data from the at least four marked data acquisition points of the subject within a preset period of time while the subject is wearing the sports bra and using the treadmill, the treadmill operating at a preset speed of 6 km/h or greater, the dynamic coordinate data acquired using the data acquirer;
the static coordinate data being used for calculating coordinate conversion;
converting the dynamic coordinate data into coordinate data in which a thoracic vertebra point is defined as an origin, and calculating displacement amplitudes of the subject's breast and a square root index S=/√S2left-right+S2up-down of the displacement amplitudes in a left-right direction and an up-down direction, the conversion and calculations performed by the data processor; and
numerically sorting the displacement amplitudes based on the square root index S using the data processor, and obtaining a grading range value, that is a grading definition for the shock absorption effect of the sports bra worn by the subject.
