Physiological Examination of New Fighting Clothing During Exposure to Exercise Under Hot Conditions

The use of fighting clothing under extreme heat conditions during rest and exercise, compromises the body's ability to maintain temperature within the narrow physiological range needed for regular function, and might lead to heat injury. Beside working and fighting clothing, the fighters also wear vests used for protection and equipment carrying, which leads to substantial reduction in effective dissipation area from the central region of the body. This fact is most substantial during exercise which increases metabolic heat production rate and leads to heat accumulation and rise in body temperature. Therefore the development of new textile technologies to allow rapid cooling during intervals is of great importance.

This study is designed to physiologically examine new textile solutions, by evaluating the physiological stress induced during exercise under mild heat conditions.
