Challenging environmental conditions involving high air temperature ( T air ) and humidity, combined with the demanding physical nature of elite endurance competition, create a risk of heat illness in elite athletes. As such, the International Olympic Committee has called for research that

between warm-up and the beginning of a race can be as long as 20 to 25 minutes. It appears that there is an increased risk of a reduction in core temperature ( T core ), with longer transitions, 4 and such a reduction in this time has been found to attenuate the overall decline in the T core

Clinical Scenario Heat is used to accelerate the metabolic rate, decrease muscle spasm, decrease pain, increase blood flow, reduce chronic inflammation, and encourage tissue elongation. 1 – 4 Modalities used to raise tissue temperature include warm whirlpools, moist hot packs (MHPs), paraffin bath

The US machine is large and stationary, forcing patients to be nonmobile for the duration of their treatment. However

In healthcare and in general living conditions body core temperature (CT) is considered one of the most informative indicators of thermal stress ( Montain, Sawka, Cadarette, Quigley, & McKay, 1994 ; Sawka et al., 2001 ), a key indicator in thermal comfort ( Gagge et al., 1967 ), and has a wide

Endurance exercise performance progressively deteriorates as the surrounding ambient temperature increases, 1 , 2 which is exacerbated when combined with increasing humidity 3 and solar radiation. 4 Importantly, comparable negative effects of the heat, albeit with a smaller magnitude, have been
