Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Baro-reflex sensitivity | 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. | 6 minutes per record. | |
Secondary | Concentration performance | Subjects will conduct a concentration test in each condition. | 4 minutes per test | |
Secondary | EEG microstates | Microstates analysis to investigate how electrical cerebral activity is affected at rest in hypoxia and influenced by low intensity cycling exercise. | 6 minutes per record | |
Secondary | Heart rate variability (HRV) | To investigate about stress (sympathetic and parasympathetic activation) in each condition tested. | 6 minutes per record | |
Secondary | Cerebral blood flow | 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. | 6 minutes per record. |
