Bland-Altman plots demonstrated mean bias limits of agreement between the thermistors and iButtons as follows ( rest , exercise , recovery ) : -@ @ , @ @ , -@ @ C ; thermistors and infrared thermometer : @ @ , -@ @ , -@ @ C ; thermistors and infrared camera ( rest , recovery ) : @ @ , @ @ C. Pairwise comparisons of -LSB- Formula : see text -RSB- found significant differences ( p < @ ) between thermistors and both infrared devices during resting conditions , and significant differences between the thermistors and all other devices tested during exercise in the heat and recovery .
