基于心率变异性的新兵跳伞训练心理应激研究
A study of mental stress in recruits during parachute training based on heart rate variability
摘要
Abstract
Objective To investigate the characteristics and evaluate the mental stress level of recruits during parachute training based on the heart rate variability. Methods Twenty new parachutists were allowed to parachute for seven times. The electrocardiograms were recorded together with data from pilot physiological parameter recorder worn by the parachutists. The data analysis system which matched with the recorder was employed to analyze the heart rate variability of the parachutists when they left from their encampment,arriving in airport and in the plane. Results As compared with the first parachute, the indices of high frequency (HF) and normalized high frequency (HFNU) of the new parachutists measured when they were at their encampment were higher than that of their fourth and seventh parachute (P＜0.01) , while the indices of normalized low frequency (LFNU) and low frequency/high frequency ( LF/HF) were lower ( P＜0.01). No statistically significant differences were detected in the new parachutists when they arrived at the airport between the three times of parachute (P＞0. 05). The index of HFNU of the seventh parachute increased significantly compared with that of the first parachute when these recruits were in the plane ( P＜0. 05). In contrast, the indices of LFNU and LF/HF declined in the seventh parachute compared with that in the first parachute, and even lower than that in the fourth parachute ( P＜0. 05). Conclusion With an increase in frequency of parachute, mental stress level of the new parachutists declines significantly when they are at their encampment and in the plane. But no eident change in stress level has been detected when they are at the airport.关键词
