al., 2015 ). Tympanic temperature measurements were used as core temperature estimates as rectal temperature is inappropriate for use in paraplegic participants ( Price & Goosey-Tolfrey, 2008 ). The data were recorded before the warm-up for the tests and immediately at the end of SSG by the same

between warm-up and the beginning of a race can be as long as 20 to 25 minutes. It appears that there is an increased risk of a reduction in core temperature ( T core ), with longer transitions, 4 and such a reduction in this time has been found to attenuate the overall decline in the T core
Repeated-Sprint Exercise in the Heat Increases Indirect Markers of Gastrointestinal Damage in Well-Trained Team-Sport Athletes

lack of GI damage following the repeated-sprint protocol in COOL conditions may be attributed to the intense but brief nature of the maximal (i.e., all-out) intervals. Moreover, final T rec was lower after exercise in the COOL compared with the HOT condition. While a rise in core temperature may not
