No arm used
No drug use for this study. No arm used in this study. Subjects are exposed to hypoxic conditions (clinical study).
Subject will conduct low-intensity exercise on a bike in different hypoxic conditions.
Other Name: Low-intensity cycling exercise
- Baro-reflex sensitivity [ Time Frame: 6 minutes per record. ]To test the strength of relationship between RR interval and systolic blood pressure in human. Measurement before and after low intensity exercise in each condition.
- Concentration performance [ Time Frame: 4 minutes per test ]Subjects will conduct a concentration test in each condition.
- EEG microstates [ Time Frame: 6 minutes per record ]Microstates analysis to investigate how electrical cerebral activity is affected at rest in hypoxia and influenced by low intensity cycling exercise.
- Heart rate variability (HRV) [ Time Frame: 6 minutes per record ]To investigate about stress (sympathetic and parasympathetic activation) in each condition tested.
- Cerebral blood flow [ Time Frame: 6 minutes per record. ]Regulation of cerebral blood flow in hypoxia at rest and during low-intensity exercise. Measurement before, during and after low intensity exercise in each condition. 6 minutes recording per measurement.
