持續(xù)工作負(fù)荷所致腦力疲勞對(duì)靜態(tài)平衡能力變化的影響
[Abstract]:Objective to study the change of static balance ability of human body under the condition of mental fatigue with continuous workload, and to evaluate the sensitivity of "bipedal sagittal position" and test method "NO reaction time" to fatigue. Methods the subjects were subjected to continuous mental load for 4 hours. Static postures were measured at 0 h, 1 h, 2 h, 3 h and 4 h, respectively. The critical frequency of flicker was measured at the time of reaction, and evaluated with NASA-TLX scale. Results the critical frequency of scintillation and the score of NASA-TLX scale increased with the time of work load, and the difference was statistically significant (P0.05). The static posture showed that the sloshing increased gradually and reached the maximum at 3 h (P0.05) and decreased slightly at 4 h. Conclusion under the continuous workload, the static balance ability decreases gradually with the load time, some gravity center sloshing indexes can reflect the fatigue state to some extent under the "double foot sagittal position" posture. The static posture test in NO response time does not sensitively reflect the fatigue state of the volunteers.
