简要总结
CB (Chemical Biological)protective clothing provides a thermal resistance between the human body and its environment. CB protective clothing will be essential for combat soldiers in case of non conventional attacks. "Lifebeam" developed a new non invasive sensor for body core temperature detection. The research purpose is to evaluate the "Lifebeam" sensor during heat tolerance test while wearing CB protective clothing.

研究组 & 干预措施
Research arm
The participants will undergo an examination day in which they will complete VO2max test to evaluate their aerobic fitness. Afterwards they'll undergo 3 heat tolerance test (HTT) days: without CB protective clothing, with CB protective clothing, and with work clothes. During the tests, a "Lifebeam" sensor will be attached to their skin.
干预措施: "Lifebeam" (Device)
结局指标
主要结局
Heat tolerance test
时间窗: 1 year
The test is performed in a climatic chamber at a temperature of 40oC and 40% relative humidity. During the test, the subject walks on a treadmill at a speed of 5 km/hr at a 2% grade for 2h. Body core temperature and heart rate are continuously monitored, and sweat rate is computed from body weight prior to and after the test, corrected for fluid intake. Heat intolerance is determined when body core temperature elevates above 38.5oC, when heart rate elevates above 150 bpm, or when either does not tend to reach a plateau.
VO2 test
时间窗: 1 year
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.
次要结局
