Cooling Via Cryogenx Body Cooling Device

Early Phase 1

Not yet recruiting

• Conditions: Body Temperature Changes
• Interventions: Device: Cryogenx cooling; Device: Regular cooling

• Registration Number: NCT06517147
• Lead Sponsor: Brunel University

Brief Summary

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.

Arm && Interventions

Group	Intervention	Description
Rate of change in core temperature during CRYOGENX cooling	Cryogenx cooling	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.
