Lawrence E. Armstrong
Professor


Presently in his 24th year as a professor in the Human Performance Laboratory. Research specialties include human fluid-electrolyte balance and assessment of hydration status; physiological responses to exercise; dietary intervention (i.e., sport drinks, low salt diets, glucose-electrolyte solutions); heat tolerance; effects of dehydration on physical performance; effects of mild dehydration on mood and cognitive performance; physiological responses to wearing uniforms; pharmacologic influences on thermoregulation and heat acclimatization as they apply to athletes, fire fighters, and military personnel.

Field studies: fluid-electrolyte balance in tennis players (Miami, FL), effects of flavoring on fluid consumption (Fort Benning, GA), heat exhaustion (Panama), heat stress monitors (Australia), heat illness (Texas), casualty rates at the Boston Marathon (Massachusetts), cooling of heatstroke patients after a summer road race (Falmouth, MA), effects of diuretic-induced dehydration on sprint running performance (Storrs, CT), observation of fluid-electrolyte and caloric turnover of cyclists during a 100-mile event in a 105F environment (Wichita Falls, TX), effects of dehydration on trail running performance (Storrs, CT), evaluation of sweat and sodium losses of elite male and female triathletes (E. Rutherford, NJ), evaluation of Ironman Triathletes at the finish line (Kona Hawaii, October 2012).

Personal Interests: (1) Effects of mild dehydration on cognitive performance and mood. (2) Changes of fluid balance and hydration biomarkers during pregnancy and lactation. (3) Effects of controlled dietary caffeine intake on fluid balance and physical performance in a hot environment. (4) Influence of fluid-electrolyte replacement beverages on prolonged exercise performance in a hot environment. (5) Novel indices of human hydration. (6) Thermoregulatory and physiological strain due to athletic uniforms. (7) Effects of modified drinking on human physiology and mood.

Holds joint appointments in the Department of Nutritional Sciences and in Physiology & Neurobiology.
