A scientific research teaching aid that can display the stress state of the lumbar spine during the weightlifting exercise of the human body

Abstract

The invention discloses a scientific research training aid capable of displaying a lumbar vertebra stress state during human body weight lifting. The scientific research training aid capable of displaying the lumbar vertebra stress state during human body weight lifting comprises a base, pressure sensors, a human body model and a displayer, wherein an annular connecting table is fixed to the upper surface of the base, cross supports are respectively arranged on the upper surface and the lower surface of the annular connecting table, the pressure sensors are respectively and vertically fixed between end points of the two cross supports, a rotating shaft is horizontally fixed to the shoulder of the human body model, large arm shafts are respectively fixed to two ends of the rotating shaft, a small arm shaft is fixed to the other end of each large arm shaft, barbells are fixed in annular rings on the left side and the right side of the small arm shaft, second power devices are fixed to the middles of the large arm shafts and the middles of the small arm shafts, and first power devices, the second power devices and the pressure sensors are connected with the displayer through connecting wires. The scientific research training aid has the advantages that the scientific research training aid can record or display mechanical parameters of the lumbar vertebra position in the movement process and is reasonable in design, simple in structure, convenient to operate and the like.

Description

technical field [0001] The invention relates to a scientific research teaching tool capable of displaying the force state of the lumbar spine during the weightlifting exercise of a human body, and belongs to the technical field of manufacturing new human kinesiology scientific research equipment. 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...
