Armstrong, Lawrence E.; Costill, David L. – Research Quarterly for Exercise and Sport, 1985
This investigation examined day-to-day variations in metabolic measurements during submaximal running and cycling. Significant differences were found in the oxygen uptake (VO2) of runners and cyclists and the minute ventilation (VE) of cyclists while running, but blood lactic acid (HLA) did not differ day to day.

Hubbard, Roger W.; Armstrong, Lawrence E. – Physician and Sportsmedicine, 1989
Reviews causes and treatment of heat syncope, heat exhaustion, and exertional heatstroke and discusses the effectiveness of cooling heatstroke victims in ice versus cooled water. Cooled water appears to be as effective, though ice water decreases the incidence of cardiovascular complications. An energy depletion model is presented. (Author/SM)

Maresh, Carl M.; Bergeron, Michael E.; Kenefick, Robert W.; Castellani, John W.; Hoffman, Jay R.; Armstrong, Lawrence E. – Journal of Strength and Conditioning Research, 2001
Examined whether moderate overhydration would enhance the performance of otherwise euhydrated collegiate swimmers during two 183-meter time-trial swims held 3 days apart. Participants swam in alternate, randomized euhydrated, and overhydrated states. Results indicated that euhydration before an intense, short-duration swim was adequate for peak…
