Examination of Textile Solutions for Reducing Physiological Stress

2015年12月23日 更新者：Sheba Medical Center

Physiological Examination of Textile Solutions for Stress Reduction When Dressed in Protective Garment and Work Clothes and Under Physical and Heat Stress Conditions

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.

详细说明

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.

武器和干预

参与者组/臂
干预/治疗
实验性的：Research arm
  1. 1 day which will include: physician examination,ECG,anthropometric measurements and Vo2max test.
  2. 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.

  3. 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:

    1. NBC protective garment (charcoal base).
    2. combat garment.
    3. 2 different types of work uniforms. physiological stress will be examined based on rectal temperature and heart rate measurements.
其他：clothing type, protective garments of Paul Boye Technologies
The experiment aimed at evaluating the physiological stress obtained when dressed in different clothing (NBC protective garment [charcoal base], combat garment and 2 different types of work uniforms- (1)50% cotton and 50% polyester (2)80% cotton and 20% polyester) and during exertion under heat conditions.

研究衡量的是什么？

主要结果指标

结果测量
措施说明
大体时间
physiological strain (composite)
大体时间：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).
10 days for each participant

次要结果测量

结果测量
措施说明
大体时间
Rectal temperature
大体时间：10 days for each participant
The rectal temperature will be monitored by a rectal thermistor during each heat tolerance test (HTT).
10 days for each participant
Skin temperature
大体时间：10 days for each participant
The skin temperature will be monitored by skin thermistors located at 3 sites (chest, arm and leg).
10 days for each participant
Heart rate
大体时间：10 days for each participant
The heart rate will be monitored using a wearable heart rate monitor (Polar® sensor and heart rate monitor watch).
10 days for each participant
Sweat rate (composite)
大体时间：10 days for each participant
Sweat rate will be calculated from the patients' body weight and fluid balance.
10 days for each participant
