Abstract:
Objective To explore the effects of mild and moderate acute hypobaric hypoxia on manual performance.Methods Using hypobaric chamber to simulate hypoxia conditions and devising 4 kinds of objective ergonomic testing items(Insert sticks into holes-board,ISIHB;nut-bolt assembly task,NBAT;shape discrimination,SD;and Grip strength,GS including fatigue and tolerance)and one subjective research item(questionnaire subjective sense)to examine manual work efficiency varieties of 9 subjects exposed to a hypobaric chamber with 5 simulated altitudes(3 500,4 000,4 500,5 000 and 5 500 m),for(25?5)min.Results Compared to control group(50 m,the altitude of Beijing):Accomplish time(AT)performance of ISIHB and NBAT significantly decreased(P
