About this study
Israel ministry of defense is examining a new protective undergarment of GORE company (chempark fabric) for the police forces. The goal of this research is to perform a comparative experiment in order to evaluate the physiological strain induced by a BC protective undergarment under exercise-heat stress conditions.
Read the detailed description
In order to physiologically evaluate a new BC protective garment for the Israeli police use under exercise-heat stress conditions, 10 young and healthy civilian volunteers will participate in this study.
The subjects will undergo 5 experiment days: Recruitment day, one day of acclimatization to heat, and 3 days of performing experiment protocol, each day dressed with different protective garment (Protective garment in current use + NBC mask, new BC protective undergarment + standard combat uniforms, new BC protective undergarment + standard combat uniforms + NBC mask).
Core (rectal) and skin temperature and heart rate will be monitored continuously, liquid balance will be recorded.the physiological heat strain will be assessed and compared between the different protective garments.

| Study group | Role | What they receive |
|---|---|---|
| Research arm | Experimental | 10 young and healthy civilian volunteers will participate in this study. The subjects will undergo 5 experiment days:
1. Recruitment , medical examination and VO2max test.
2. Acclimatization day by performing moderate exercise protocol under hot and humid climate.
3. 3 days of performing moderate exercise under hot and humid conditions protocol, each day dressed with different protective garment:
1. Protective garment in current use + NBC mask.
2. The new BC protective undergarment + standard combat uniforms

What is being measured
The primary outcome is the main question the study is designed to answer.
physiological strain (composite)
The physiological strain will be determined by body core temperature and heart rate of the subjects during a heat tolerance test (HTT).
Measured: 4 days for each participant
Secondary outcomes (4)
Rectal temperature
The rectal temperature will be monitored by a rectal thermistor during each heat tolerance test (HTT).
Measured: 4 days for each participant
Skin temperature
The skin temperature will be monitored by skin thermistors located at 3 sites (chest, arm and leg).
Measured: 4 days for each participant
Heart rate
The heart rate will be monitored using a wearable heart rate monitor (Polar® sensor and heart rate monitor watch).
Measured: 5 days for each participant
Sweat rate (composite)
Sweat rate will be calculated from the patients' body weight and fluid balance.
Measured: 4 days for each participant

Questions about this trial
What is this clinical trial studying?
A study testing exercise under hot and humid conditions protocol in people with Physiological Stress, run by Sheba Medical Center at 1 site in Israel.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 24 Dec 2015. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Israel. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
physiological strain (composite) (time frame: 4 days for each participant). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Dec 2015.
