A scientific research teaching aid that can display the stress state of the lumbar spine when lifting dumbbells with both arms

Abstract

The invention discloses a scientific research teaching aid capable of displaying lumbar stress state when both arms lift dumbbells. The scientific research teaching aid comprises a base, a pressure sensor, a human body model and a display, wherein the pressure sensor is fixed between the human body model and the base, the human body model is a model of a human body part above the waist, a rotating shaft is horizontally fixed to a shoulder portion of the human body model, first power devices are fixed to two sides of the shoulder portion of the human body model, a second power device is fixed to the human body model, and both the first power devices and the second power device are connected with the display. The scientific research teaching aid is capable of recording or displaying mechanical parameters of a lumbar portion when both arms of a human body lift the dumbbells and has the advantages of reasonable design, simple structure, operational convenience 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 when dumbbells are lifted with both arms, 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...
