The SNIPER-TBI study aims to identify and quantify the risk of mild traumatic brain injury (mTBI) in soldiers of the Czech Armed Forces during specific high-risk training activities, including parachute jumps, high-caliber firearms shooting, artillery blasts, and Close Quarters Battle (CQB) exercises. The study will utilize both diagnostic biomarker analysis and experimental biomechanical measurements to assess the physiological impact of these activities on brain health. The ultimate goal is to reduce mTBI incidence, improve operational readiness, and extend the active service duration of soldiers through targeted preventive measures.

The SNIPER-TBI study aims to quantify the risk of mild traumatic brain injury (mTBI) in Czech Armed Forces soldiers during high-risk training activities, including parachute jumps, high-caliber firearms shooting, artillery blasts, and Close Quarters Battle (CQB) exercises. The study combines diagnostic biomarker analysis (GFAP, UCH-L1) and experimental biomechanical measurements using wearable sensors and high-speed cameras. These data will provide critical insights into the forces exerted on the brain during training and help establish exposure limits to minimize long-term neurological impairment. The results will guide the development of protective strategies and enhance soldier readiness.
