About this study
Official title: Efficacy of Post Exercise Heat Stress Cooling Via Cyrogenx Body Cooling Device
The aim of this project is to test the rate of cooling following exercise in the heat utilising the CRYOGENX Cryosuit device i) against passive cooling, and ii) to quantify the rate of cooling and compare this rate with established cooling intervention thresholds i.e. -0.11 to 0.15°C.min-1. As this project is to determine the efficacy of the intervention in populations equivalent to sporting and military personnel, these aims will be tested in young (18-40 year old) healthy male and female participants whom participate in regular physical activity. As a commercially funded project, the experimental design implemented will closely replicate that of the independent investigation into the efficacy of the CAERvest® device.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Cryogenx coolingDevice
During the cooling phase of both trials established field based cooling approaches e.g., temperate temperature water spraying (30°C, 5 mL.min-1), and air circulation (electric fan 2 m distance, 1.7 m.s-1 will be implemented. During the CRYOGENX cooling trial, the product will be affixed to the participant's torso in accordance with manufacturer's instructions and they will receive cooling via this intervention in addition to water spraying and air circulation. During the control visit, no intervention will be applied however water spraying and air circulation will be received.
Regular coolingDevice
During the cooling phase of both trials established field based cooling approaches e.g., temperate temperature water spraying (30°C, 5 mL.min-1), and air circulation (electric fan 2 m distance, 1.7 m.s-1 will be implemented. During the CRYOGENX cooling trial, the product will be affixed to the participant's torso in accordance with manufacturer's instructions and they will receive cooling via this intervention in addition to water spraying and air circulation. During the control visit, no intervention will be applied however water spraying and air circulation will be received.
| Study group | Role | What they receive |
|---|---|---|
| Rate of change in core temperature during CRYOGENX cooling | Experimental | Participants will visit the laboratory on three occasions during this randomized, counter-balanced crossover study. The first visit will enable preliminary data collection and familiarisation to take place. The second and third visits will be experimental sessions (CRYOGENX cooling vs regular cooling), with the order of these randomised. The rate of change in core temperature during cooling observed in the two trials will be compared by paired sample t-tests. Receives: Device: Cryogenx cooling |

Questions about this trial
What is this clinical trial studying?
A Early Phase 1 study testing Cryogenx cooling and Regular cooling in people with Body Temperature Changes, run by Brunel University.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
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: status not confirmed, as of the sponsor's last update on 24 Jul 2024. Status can change between updates, so confirm with the study contact before making plans.
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.
What does this phase mean?
Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Oliver R Gibson, PhD (+44(0)1895 267957 ext. 7957, oliver.gibson@brunel.ac.uk), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Core (rectal) temperature (time frame: 12 months). 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 Jul 2024.
