Abstract:

Comparison of Esophageal, Rectal, and Gastrointestinal Temperatures During Passive Rest After Exercise in The Heat: The Influence of Hydration It is unknown how valid esophageal, rectal, and gastrointestinal temperatures (TES, TRE, and TGI) compare after exercise-induced hyperthermia in various hydration states. The purpose of this study was to examine the differences between TES, TRE, and TGI during passive rest following exercise-induced hyperthermia under two different hydration states: euhydrated (EU) and hypohydrated (HY). Randomized-crossover design. Controlled laboratory setting. Nine recreationally active male participants (mean± SD; age, 24±4; height, 177.3±9.9cm; body mass, 76.7±11.6kg; body fat, 14.7±5.8%). Participants completed two trials (EU and HY) consisting of a bout of treadmill exercise (a 10 minute walk ranging 4.8-7.2km·hr(-1) at a 5% grade followed by a 20 minute jog ranging 8.0-12.1km·hr(-1) at a 1% grade) in a hot environment (ambient temperature, 39.3±1.0°C; relative humidity, 37.6±6.0%; wet bulb globe temperature, 31.3±1.5°C) followed by passive rest. Root mean squared difference (RMSD) was used to compare the variance of temperature readings at corresponding time points for TRE vs TGI, TRE vs TES, and TGI vs TES in EU and HY. RMSD values were compared using three-way repeated measures ANOVA. Post hoc analysis of significant main effects was done using Tukey's HSD with significance set at p<0.05. RMSD values (°C) for all device comparisons were significantly different in EU (TRE - TGI, 0.11±0.12; TRE - TES, 1.58±1.01; TGI - TES, 2.04±1.19) than HY (TRE - TGI, 0.22±0.28; TRE - TES, 1.27±0.61; TGI - TES, 1.16±0.76) (p<0.01). Across the 45- minute bout of passive rest, there were no differences in TRE, TGI and TES between EU and HY trials (p=0.468). During passive rest after exercise in the heat, TRE and TGI were in good agreement when tracking body temperature, with a better agreement appearing in those maintaining a state of euhydration versus those who became hypohydrated during exercise; however, this small difference does not appear to be of clinical significance.
