OBJECTIVE To study the effects of 21 d -6 degrees head down bed rest (HDBR) with exercise training on dynamic posture equilibrium and motor coordination. METHOD Ten healthy young men were randomly divided into HDBR control groups and HDBR exercise groups, with 5 in each group. The subjects in the exercise group performed exercise with a bicycle ergometer(More)
OBJECTIVE To study the related factors of emotional stability in flight. METHOD Based on the operable definition of emotional stability in flight and the related literature review, 63 experienced pilots and flight coaches were investigated and the other-rating questionnaire of emotional stability in flight was established. To test the senior nerve system,(More)
Objective. To observe the changes of energy metabolism of brain tissue in rats under +Gx loads, and to explore its possible role in changes of brain function and work efficiency induced by +Gx stress. Method. Forty-five male Wistar rats were randomly divided into control, +5 Gx, +10 Gx, +15 Gx and +20 Gx group. Each group was exposed to the corresponding G(More)
OBJECTIVE To observe the protective effects of exercise training during 21 d -6 degrees head down bed rest (HDBR) on bone loss. METHOD Ten healthy young men were randomly divided into HDBR group and HD-BR exercise group, with 5 in each group. Both groups were exposed to -6 degrees head down bed rest for 21 d. The subjects in the exercise group performed(More)
OBJECTIVE To compare heart rate variability (HRV) and heart rate (HR) between individuals with different emotional stabilities in two situations and to discuss the relationship between situation, emotional stability and HRV. METHOD Ninety-six healthy male flying students were assessed after 60 h flying exercises by senior pilots using Criterion Assessment(More)
OBJECTIVE To established models of confirmatory factor analysis of the emotional stability criteria of flying students, and to provide an available criteria tool for evaluating the emotional stability. METHOD "Criterion Assessment Scale of Emotional Stability of Flying Cadets" (ACSEFC) including 9 items were compiled first by interviewing with skillful(More)
Effects of LBNP is similar to that produced by gravitational force, especially as a stress factor on the cardiovascular system as has been concerned in the area of aerospace medicine. This paper described experimental equipment, methods and physiological effects of LBNP, especially its application in the area of aerospace medicine. Several aspects for(More)
