FIT, NOURISHED AND RESILIENT
WEARABLE INFORMATION
A Soldier puts on an Equivital chest harness, which incorporates USARIEM’s ECTemp algorithm to record heart rate changes over time. The heart rate indicates how much blood flows to muscles and the skin, from which researchers can extrapolate how much heat is being generated and lost by the body. Medics and leaders looking to prevent heat illness in Solders can monitor Soldiers’ body temperatures if the ECTemp technology is included in a wearable monitor like the chest harness.

servicemen and women’s health and performance during train- ing and on the battlefield. “USARIEM partners with DOD, other federal entities, universities, nonprofits and industry stakeholders extensively to answer military-relevant questions and optimize Soldiers’ health, resilience and performance,” said Col. Raymond Phua, commander of USARIEM.
USARIEM’s location at Natick Soldier Systems Center, a 30- minute drive west of Boston, puts the lab in close proximity to the extensive academic, federal and commercial knowledge and research assets of the Northeast corridor, giving research- ers access to top potential collaborators. USARIEM is one of the very few labs in the world where all aspects of HPO come together.
While the lab looks at HPO through a biomedical or a bioen- gineering lens, USARIEM’s holistic approach to attaining an
“optimized performance state,” as Dr. Karl Friedl, USARIEM’s senior research scientist for performance physiology described it, sets the lab apart. Friedl also explained that the unique and critical research capabilities that USARIEM provides to the DA, DOD and the nation are the synergy of subject matter expertise on performance, nutrition, environmental stressors and biomed- ical modeling from civilian researchers and Soldier scientists.
“Te Army will always have Soldiers holding terrains in parts of the world that have extreme environments, and as long as we continue to encounter threats near and far, warfighters will always encounter risks,” Friedl said. “Tis makes an optimized performance state sound like an elusive goal. While we cannot eliminate these risks, we can mitigate them.
“USARIEM is the only lab that has looked at all aspects of Sol- diers’ physical and cognitive performance, in terms of health, occupation and the environments they work in. We aim to sus- tain the health and fighting ability of warfighters by developing military medical doctrine and technology that will give war- fighters the ability to meet the physical and cognitive demands of any combat or duty position, accomplish the mission and continue to win present and future fights.”
USARIEM’s internationally recognized research leaders are exe- cuting and supporting key products and strategic doctrine shifts, which include the U.S. Army Training and Doctrine Command (TRADOC) project to examine the knowledge, skills, abilities and other attributes associated with military occupational spe- cialties (MOSs), as well as the Army surgeon general’s 2020 strategy of shifting to a system of health through the areas of performance and nutrition, with the goal of attaining high- quality, longer lives free of preventable disease, disability, injury and premature death.
Here are some of the emerging USARIEM technologies, medi- cal doctrine and future research efforts to optimize warfighter health and performance in a variety of occupational environ- ments and situations.
EMERGING USARIEM TECHNOLOGIES Te Estimated Core Temperature (ECTemp) algorithm accu- rately estimates a Soldier’s core body temperature simply by analyzing heart rate changes over time. Physiologically, heart rate reflects both the blood flow to the muscles and the rate of blood flow to the skin, containing information about both heat production and heat loss from the body. ECTemp can be
