A Comprehensive Test of Multi-sport Physiological Index Weightless Aircraft

Abstract

The invention discloses a multi-sport physiological sign zero-gravity airplane comprehensive test. A human body operation sport characteristic testing support, an equipment platform, a treadmill, a visual perception characteristic testing system and a biological rhythm influence testing platform are included. Performance data formed during pushing, pulling and two-arm rotation operation of a person in the zero-gravity flight state can be obtained, and verification of a biomechanical model in the zero-weight environment is supported; force distribution data of shoulder and waist portions of a treadmill testee are measured and obtained, bases are provided for improving and perfecting a treadmill bonding system, and the problems existing in the design of an aerospace treadmill are further analyzed by comparing the difference between the running motion gestures on the ground and the zero-weight airplane; the performance data obtaining effectiveness of the visual perception characteristic testing system in the variable-weight environment is verified. The influence of short and repeated zero weight simulated by the zero-weight airplane on model organism gravity stress gene expression and biological rhythm is discussed, and a molecular mechanism of a biological clock affected by gravity changes is discovered.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a multi-sport physiological index weightless aircraft comprehensive test. Background technique [0002] The weightless aircraft is a special-purpose aircraft refitted from an ordinary aircraft. It is an important large-scale experimental site and device in the manned spaceflight program. [0003] Weightlessness is a special environmental factor that always exists in the spaceflight process. Many domestic and foreign research materials show that some physiological functions of the human body have changed in the weightlessness environment of space. With the continuous development of aerospace technology, research on the physiological effects of weightlessness such as weight loss and muscle atrophy of the lower limbs has become more urgent. [0004] Treadmill exercise is the main protective measure against the effect of weightlessness in astronaut training and spaceflight. At pr...
