The use of infrared thermography for the dynamic measurement of skin temperature of moving athletes during competition; methodological issues

Objective . To investigate the use of infrared thermography (IRT) for skin temperature measurement
of moving athletes during competition and its sensitivity to factors that are traditionally
standardised. Approach . Thermograms were collected for 18 female athletes during the 20 km racewalk
at the 2019 World Athletics Championships, with a medium-wave, cooled indium antimonide medium wave
infrared band (MWIR) and a long-wave, uncooled microbolometer longwave infrared band (LWIR) infrared
camera. Main results . The MWIR provided greater clarity images of motion due to a shorter exposure
and response time and produced a higher percentage of acceptable images. Analysing acceptable images
only, the LWIR and WMIR produced good levels of agreement, with a bias of −0.1 ± 0.6 °C in mean skin
temperature for the LWIR. As the surface area of an ROI was reduced, the measured temperature became
less representative of the whole ROI. Compared to measuring the whole area ROI...
