Human Fundamental Upward Movement; Spiral Trajectory and Walking of 3D + 1D Space and Time

Background: There are few biomechanical studies on the physical transfer of a person lying on a floor or bed perpendicular to the direction of gravity. Basic biomechanics research can be an important source. This study aimed to analyze the biomechanical properties of the upward movement of the floor in the supine position.Methods: Healthy volunteers were recruited by snowball sampling. The movement from the supine position to upward movement on the carpet floor was repeated three times. The three procedures were analyzed with an 11 segments model using a 3D motion analysis Move Tr 3D (Library©) under the 4 CCD cameras. The analysis of the motion trace was examined. The movement of the reflection marker with respect to the Z-axis was analyzed with the vertical direction of the gravity as the Z-axis. It was observed from the XY plane, XZ plane, ZY plane, and how many dimensions the reflection marker took was analyzed. Results: Five healthy volunteers (Medium age 27 years, Female) who received written consent to the study were investigated. A spiral motion was observed in the trajectory of all reflection markers. A walking motion was observed in which the right and left sides of the body alternately swam to the back. Each reflex marker body site was moving headward as if contacting the floor with either the left or right side having 0 to the vertical Z-axis of gravity; the opposite left or right side walked with repeated movements floating from the floor and raising the Z coordinate. 3D Space + 1D time were observed in the human fundamental upward movement.Conclusion: The Human Fundamental Upward Movement on the floor was observed Spiral Trajectory and the Walking of 3D+1D Space and Time.KEYWORDS: Human Fundamental Movement, Upward movement, Positioning Change, Transfer, Biomechanics
