简要总结
Using protective or combat garments under heavy heat stress conditions, during rest or exertion, may hinder the body's ability to effectively exchange heat with the environment and thereby can lead to heat injuries. The purpose of this research is to physiologically examine the new textile solutions that are planned to be integrated in the protective garments, combat garments and work uniforms in the army, by evaluating the physiological stress obtained during exertion under hot climatic conditions.
详细描述
10 young, healthy civilian volunteers will participate in this study. After reading and signing an informed consent form, all subjects will undergo medical examination which includes ECG, anthropometric measurements and Vo2max test. Afterwards, the subjects will perform 6 acclimatization days carried out by the standard protocol of Heat Tolerance Test (HTT). After acclimatization, the subjects will undergo 4 experiment days under heavy heat stress in a climatic chamber, dressed in each experiment day with one out of 4 clothing combinations (NBC protective garment [charcoal base], combat garment and 2 different types of work uniforms). Physiological stress will be evaluated from rectal temperature and heart rate measurements.

研究组 & 干预措施
Research arm
-
1 day which will include: physician examination,ECG,anthropometric measurements and Vo2max test.
-
6 acclimatization days carried out by a standard protocol including a daily 2 hour effort performed in a climatic chamber, which include walk on a treadmill at 5 Km/h on a 2% incline under heat conditions (40 deg. centigrade & 40% HR) and when dressed in shorts.At the sixth day, the subjects will be dressed in a standard work uniform as a baseline exposure. Core (rectal) and skin temperature and heart rate will be monitored continuously.
-
4 experiment days carried out by the following protocol: 2 hour walk on a treadmill (5 Km/h,2% incline) under heavy heat stress conditions (30 deg. centigrade,60% RH) and when dressed each time with different clothing out of 4 options:
-
NBC protective garment (charcoal base).
-
combat garment.
-
2 different types of work uniforms. physiological stress will be examined based on rectal temperature and heart rate measurements.
干预措施: clothing type, protective garments of Paul Boye Technologies (Other)
结局指标
主要结局
physiological strain (composite)
时间窗: 10 days for each participant
The physiological strain will be determined by body core temperature and heart rate of the subjects during a heat tolerance test (HTT).
次要结局
- Rectal temperature(10 days for each participant)
- Sweat rate (composite)(10 days for each participant)
- Heart rate(10 days for each participant)
- Skin temperature(10 days for each participant)
