Clinical Trial Summary

This study is investigating the efficacy of CORE™ devices in calculating core body temperature in athletes under varying environmental conditions.


Description:

As athletes exercise, their core body temperature rises, which can affect their performance. Additionally, repeated mild to moderate heat stress, heat acclimation, can be used to improve exercise tolerance and performance. Thus, an athlete can gain performance benefits through monitoring their heat loading while training. The aim of this study is to compare the CORE™ body temperatures recorded during exercise in two different environmental conditions in which the investigators will get a separation of core temperature and skin temperature. The investigators will accomplish this by recruiting trained and elite athletes, ages 18-59, to participate in two exercise sessions in the heat at low (10-20%) and high (80-100%) relative humidity. The investigators will compare the CORE™ temperature estimates against an FDA approved ingestible temperature monitoring device to assess the accuracy of the CORE™ devices.

Intervention

Device:
Core body temperature device
This study is to verify the claims of CORE™ body temperature system to estimate core body temperature from skin temperature and heart rate during exercise under varying environmental conditions. Subjects will ingest a temperature sensing pill and be outfitted with skin temperature sensors, a chest strap heart rate monitor, and the CORE and CaleraResearch devices. Athletes will run or cycle in hot/dry and hot/humid conditions for 45 minutes at an absolute workload of 60% VO2 Max/Peak.

Outcome

Type Measure Description Time frame Safety issue
Primary Ability to accurately estimate core body temperature The CORE and CaleraResearch devices estimate core body temperature using single-site skin temperature and heartrate as data inputs for their proprietary algorithm. This calculated temperature will be assessed against actual core body temperature, measured with an FDA approved, ingestible, temperature-sensing telemetry pill. 30 minutes
