Solar radiation and the validity of infrared tympanic temperature during exercise in the heat
We investigated the validity of infrared tympanic temperature (IR-T ty ) during exercise in the heat with variations in solar radiation. Eight healthy males completed stationary cycling trials at 70% peak oxygen uptake until exhaustion in an environmental chamber maintained at 30°C with 50% relative...

| Zusammenfassung: | We investigated the validity of infrared tympanic temperature (IR-T
ty
) during exercise in the heat with variations in solar radiation. Eight healthy males completed stationary cycling trials at 70% peak oxygen uptake until exhaustion in an environmental chamber maintained at 30°C with 50% relative humidity. Three solar radiation conditions, 0, 250 and 500 W/m
2
, were tested using a ceiling-mounted solar simulator (metal-halide lamps) over a 3 × 2 m irradiated area. IR-T
ty
and rectal temperature (T
re
) were similar before and during exercise in each trial (
