Remote ischemic preconditioning improves tissue oxygenation in a porcine model of controlled hemorrhage without fluid resuscitation Open
Remote ischemic preconditioning (RIPC) involves deliberate, brief interruptions of blood flow to increase the tolerance of distant critical organs to ischemia. This study tests the effects of limb RIPC in a porcine model of controlled hemo…

A prospective study of the utility of pre-induction tests as predictors of attrition in infantry recruits Open
BackgroundSoldiers in modern armies perform tasks that are increasingly technologically dependent. Training them to obtain necessary technological skills is both complex and expensive. Personnel attrition is costly and can affect military …

Mild Physical Activity Does Not Improve Spatial Learning in a Virtual Environment Open
It is well-established that physical exercise in humans improves cognitive functions, such as executive functions, pattern separation, and working memory. It is yet unknown, however, whether spatial learning, long known to be affected by e…

Cognitive Effects of Astaxanthin Pretreatment on Recovery From Traumatic Brain Injury Open
Traumatic brain injury (TBI), caused by mechanical impact to the brain, is a leading cause of death and disability among young adults, with slow and often incomplete recovery. Preemptive treatment strategies may increase the injury resilie…

Rhabdomyolysis After Crawling Military Training Open
Thus, we suggest that the extreme creatine phosphokinase levels may be attributed to a synergistic interaction between low-energy trauma, caused by crawling on hard soil and stones, and exertion. We also emphasize the fact that proper phys…

Misdiagnosis of Exertional Heat Stroke and Improper Medical Treatment Open
Exertional heat stroke (EHS) is the most complicated and dangerous amongst heat injuries that can lead to irreversible injury and even death. Early diagnosis and treatment are therefore crucial determinants of the patient's prognosis. The …

Return to duty/play after exertional heat injury: do we have all the answers? A lesson from two case studies Open
Susceptibility to heat is a significant determinant for active young people such as athletes and soldiers. Both cases emphasize the importance of the heat tolerance test (and repeated test when needed) as a criteria for an exertional heat …

The load carriage index (LCI) - adjusting the load carried by the soldier according to body composition measurements Open
Lean body (LBM), strongly correlates with absolute maximal oxygen uptake (VO2max), has been shown to predict load carriage performance [1]. In contrast, fat is considered dead mass (DM) that reduces mobility and effectiveness of the carr…
