In this paper, the aim was to study Heart Rate Variability during rest and exercise in normobaric hypoxia environment using sample entropy. Sample entropy is a powerful way to analyze non-linear biological system, it’s the first time to analysis hypoxia exercise HRV signal by sample entropy.12 healthy males took part in the experimentation, some of them were asked to stay in the hypoxia cabin for 150 min every day. It’s divided into three 30 min rest periods and three 20 min exercise periods, the rest and exercise period was across. Subjects’ heart rate and SaO2 data were collected. The sample entropy of rest period was compared with exercise period, there’s statistical difference between them. Our results indicate that hypoxia exerts an influence on HRV, it also suggest that acute exposure to normobaric hypoxia induce increases in sympathetic vasomotor activity and cardiac sympathetic dominance result an increased heart rate.
