Experimental: sleep deprivation
The research contains only one arm. The subjects will be tested with no sleep deprivation (which will be used as a control measurement) and with partial and complete sleep deprivation.
Other: partial and complete sleep deprivation
The subjects will visit our labs 4 times. The second visit will be used as the experimental control. During the third and fourth visits the subject will go through an exercise heat tolerance test and a measurement of their physiological efficiency after a partial and complete sleep deprivation, respectively.
- oxygen consumption [ Time Frame: experimental days 1,3,4 ]volunteer's oxygen consumption (VO2) will be monitored continuously with a metabolic chart (ZAN), while running for 10 min on a treadmill under comfortable environmental conditions.Each volunteer will undergo the test 4 times.
- Skin temperature [ Time Frame: experimental days 2,3,4 ]The volunteers will undergo Heat Tolerance Test (HTT). Their skin temperature will be measured by skin thermistors and will be monitored continuously and viewed by the attending medical staff. Automatically all data will be recorded by the monitoring Biopac system.
- Rectal temperature [ Time Frame: experimental days 2,3,4 ]The volunteers will undergo heat tolerance test. Their rectal temperature will be measured by rectal thermistor and will be monitored continuously and viewed by the attending medical staff. Automatically all data will be recorded by the monitoring Biopac system.
- Heart rate [ Time Frame: experimental days 1,2,3,4 ]During the HTT (Heat Tolerance Test) and the VO2 test heart rates will be monitored continuously and will be stored by a heart rate wristwatch, (POLAR, Finland).
