Lawrence E. Armstrong, PhD

Professor Emeritus

Kinesiology


Research Overview

My research specialties include human fluid-electrolyte balance and assessment of hydration status; physiological responses to exercise; dietary interventions (i.e., sport drinks, low salt diets, glucose-electrolyte solutions); heat tolerance; effects of dehydration on performance; physiological responses to wearing uniforms; pharmacologic influences on thermoregulation and heat acclimatization as they apply to athletes, fire fighters, and military personnel. The one theme that ties all of these specialties together is the human response and adaptation to exercise. I have conducted research at several mass participation endurance events such as; Boston Marathon, Marine Corps Marathon, Falmouth Road Race, and the Ironman Triathlon World Championship. Additionally, I have made it a career goal to make certain that laboratory and field investigations culminated in publication of peer reviewed journal articles; I have published a total of 180 peer reviewed publications as first author or co-author, dating back to 1983. In recent years, I have completed research studies in the HPL that focused on (a) effects of mild dehydration on cognitive performance and mood in men and women, and (b) hydration status of women across the term of pregnancy and during breast-feeding.
