Abstract

The experienced discomfort of rectal probes and esophageal probes for the estimation of body core temperatures has triggered the development of GI-capsules that are easy acceptable for athletes and workers due to their non-invasive characteristics.
 We compare two new GI-capsule devices with rectal temperature during cycle ergometer exercise and rest. Eight participants followed a protocol of (i) 30 min exercise with a power output of 130 W, (ii) 5 min rest, (iii) 10 min self-paced maximum exercise, and (iv) 15 min rest. Core temperature was measured using two GI-capsule devices (e-Celsius and myTemp) and rectal temperature.
 The myTemp system gave temperatures indifferent different from rectal temperature during rest and exercise. However, the factory calibrated e-Celsius system, showed a systematic underestimation of rectal temperature of 0.2 °C that is corrected in the 2018 versions. Finally, both GI-capsules react faster to temperature changes in the body compared to the rectal temperature probe during the rest period following maximum exercise.
