Research teaching aid for analyzing human body lumbar spine force in weightlifting process

Abstract

The invention discloses a research teaching aid for analyzing human body lumbar spine force in a weightlifting process. The research teaching aid comprises a base, pressure sensors, a human body model and a display. The upper surface of the base is fixed with a spherical connecting table. Upper and lower surfaces of the spherical connecting table are respectively provided with cross brackets. The pressure sensors are vertically fixed between end points of the cross brackets. The shoulder portion of the human body model is fixed horizontally with a rotary shaft. Two ends of the rotary shaft are respectively fixed with large arm shafts. The other end of each large arm shaft is fixed with a small arm shaft. Barbells are fixed in annular rings at left and right sides of each small arm shaft. Second power devices are fixed between the large arm shafts and the small arm shafts through shaft pins. Connecting wires of a first power device, the second power devices and the pressure sensors are connected with the display. The beneficial effects of the invention are in that the research teaching aid is capable of recording or displaying the mechanical parameters of the lumbar spine during movement; and the entire teaching aid has the advantages of easy barbell adjustment, reasonable design, simple structure, easy operation and so forth.

Description

technical field [0001] The invention relates to a scientific research teaching tool for analyzing the force of the lumbar spine of a human body during the weightlifting process, and belongs to the technical field of new human kinesiology scientific research equipment manufacturing. Background technique [0002] Studying and exploring the stress state of the human lumbar spine during weightlifting can improve the scientific research level of human motion mechanics, prevent weightlifters from being injured in training and competitions, and can guide and improve the training effect of athletes. Although there are sports that rely on computers Three-dimensional simulation software, but it is biased towards theoretical analysis. In practical applications, there is a lack of mechanical devices that can directly reflect the force of the human lumbar spine in different directions during weightlifting, which restricts the timely application of sports mechanics in actual training of at...
