Effect of a Cooling Kit on Physiology and Performance Following Exercise in the Heat
Cody R. Smith, Cory L. Butts, J.D. Adams, Matthew A. Tucker, Nicole E. Moyen, Matthew S. Ganio, and Brendon P. McDermott
Exercising in a hot environment increases hyperthermia, which can lead to heat exhaustion or exertional heat stroke. Exercise-induced hyperthermia can reach critical levels when the body’s internal (core) temperature exceeds 40°C. 1 If an individual suffers exertional heat stroke, lowering core
Efficacy of Cold Water Immersion Prior to Endurance Cycling or Running to Increase Performance: A Critically Appraised Topic
Connor A. Burton and Christine A. Lauber
Clinical Scenario Intense aerobic exercise can produce metabolic heat at a rate of 20 kilocalories per minute in elite athletes. Heat production, therefore, can equate to a core temperature (T c ) increase of 1°C every 5–7 min. 1 The rise in T c can challenge thermoregulation of the body and
Does Precooling With Whole-Body Immersion Affect Thermal Sensation or Perceived Exertion? A Critically Appraised Topic
Timothy M. Wohlfert and Kevin C. Miller
Abbreviations: BSA, body surface area; CON, control; ht = height; N/A, not available; PC, precooling; RH, relative humidity; RPE, rating of perceived exertion; T core , body core temperature; T skin , skin temperature; TS, thermal sensation. Note: All data are reported as mean (SD); data were rounded to the
Contribution of American Football Uniforms to the Development of Exercise-Induced Hyperthermia: A Critically Appraised Topic
Grace Katt and Kevin C. Miller
Exertional heat stroke (EHS) is the most severe form of exertional heat illness (EHI) and is diagnosed when an athlete’s body’s core temperature exceeds 40.5 °C (105 °F) and they display central nervous system dysfunction. 1 EHS is one of the leading causes of sudden death in athletes. 2 In

limitations, a rectal temperature could not be determined, which is considered the gold standard in measuring body-core temperature; only an oral thermometer was available and was not used, as it is known to be an unreliable measure of body-core temperature following exercise. 7 Priority was placed on

status and loss of consciousness, the trainee was also evaluated for EHS. His initial core temperature (Tc) measured 41.61 °C, and he was immediately placed in an ice water immersion tub. The trainee’s rectal temperature dropped to 39.39 °C after 11 minutes (see Table 2 ). Table 2 Timeline of Events
