Higher insulation levels during exercise increase esophageal temperature (Tes) more than rectal temperature (Tre). Tes is a more sensitive indicator of heat stress from insulation than Tre during and after exercise.

Area of Science:

  • Exercise Physiology
  • Environmental Physiology
  • Human Thermoregulation

Background:

  • Understanding thermoregulation during exercise is crucial for performance and safety.
  • Insulation levels significantly impact heat exchange between the body and the environment.
  • Esophageal temperature (Tes) and rectal temperature (Tre) are common core body temperature indicators.

Purpose of the Study:

  • To evaluate the impact of varying insulation levels on Tes and Tre responses during and after moderate exercise.
  • To compare the sensitivity of Tes versus Tre in reflecting heat stress induced by different insulation levels.

Main Methods:

  • Seven subjects performed 18-minute treadmill exercise bouts at 75% VO2max in 22°C ambient temperature.
  • Subjects wore three insulation conditions: athletic clothing, coveralls, and a nuclear, bacteriological, and chemical (NBCW) overgarment.

  • Tes and Tre were monitored during exercise and a 30-minute recovery period.

    • Main Results:

    • The rate of Tes increase during exercise was significantly higher with greater insulation (NBCW overgarment > coveralls > athletic clothing).
    • End-exercise Tes and post-exercise plateau Tes were significantly elevated with increased insulation.
    • Tre showed less pronounced differences between insulation conditions, with only the NBCW overgarment condition showing a significant increase.

    Conclusions:

    • Esophageal temperature (Tes) is a more sensitive index of heat stress from varying insulation levels during and after exercise compared to rectal temperature (Tre).
    • Increased insulation significantly elevates core body temperature responses during and following moderate exercise.
    • Physiological mechanisms underlying these differential temperature responses warrant further investigation.
