Abstract
Abstract This paper first briefly introduces the early warning indicators and techniques of G-induced human loss of consciousness that is G-LOC under G load action,and puts forward the necessity of exploring and studying EMG signal under G load. EMG signals of the human body are obtained from the human centrifuge, and EMG under G load is analyzed by using the two-condition analysis method in foreign literature. Different from the research in foreign literature, in addition to studying the EMG characteristics under centrifuge G load, the change characteristics of EMG at other muscles are also investigated. The effectiveness of EMG for early warning of G-LOC is explored. The result verifies the efficiency of the two-condition analysis method, suggesting that the specific parameters at the particular parts show characteristic change, which is valuable for early warning of G-LOC under high G load. At the same time, it further proves that the EMG change of gastrocnemius is more effective than that of tibialis anterior. The study lays a foundation for the follow-up research on monitoring and early warning technology of G-LOC by EMG and has important reference value.
