Understanding heat regulation during exercise in military personnel

Official title: Study of Thermoregulation in Exercise Heat Stroke in the Military Environment

Run by Direction Centrale du Service de Santé des Armées · NCT05847465 · Data updated 2026-11-12

This study is testing how well military personnel can handle heat during exercise to see if they are heat tolerant or not, which could help improve safety during training.

Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are military personnel who have undergone exercise heat stroke and are currently trained or re-trained with a minimum of two aerobic sessions per week.

Probably not a fit

Patients currently on medication or those with specific contraindications, such as certain digestive issues or electronic implants, may not benefit from this study.

What this trial studies

This observational study focuses on assessing thermoregulation in military personnel who have experienced exercise-induced heat stroke. It utilizes a Heat Tolerance Test (HTT) conducted in a controlled environment to evaluate physiological responses such as heart rate, skin temperature, and sweat loss. The study aims to differentiate between individuals who are heat intolerant and those who are heat tolerant, providing valuable insights into their thermophysiological profiles. The findings could enhance understanding of heat-related illnesses and improve safety protocols in military training.

Why it matters

Potential benefit: If successful, this study could lead to improved strategies for preventing heat stroke in military personnel during training and operations.

How similar studies have gone: While the approach of using controlled heat tolerance testing is established, this specific application in military personnel is relatively novel and has not been extensively tested in similar contexts.
