Contribution of L-Tyrosine to Recovery From Operational Strain on Return From External Operation

• Status: Recruiting
• Trial end date: 2022-09-01
• Target enrollment: 0
• Participant gender: All

Summary

Operational conditions amplify soldier's constraints and stress factors, upsetting individual and collective adaptive landmarks. The soldier's resistance is strained by the high intensity of stressors, by the long duration of exposure and by their cumulative effect.

This may lead to a state of "operational strain" that refers to chronic stress and the allostatic load imposed by operational constraint.

The investigators believe that operational strain could manifest itself by a kind of accelerated aging of the organism due to the increased allostatic load without sufficient resource restoration (neurotransmitter precursors, partial and repeated sleep deprivation, etc.).

This aging mechanism would be reversible after a sufficient period of resource restoration (sleep, physical activity, adapted diet, etc.).
