Abstract
This study examined the use of insulation disks placed on the skin to estimate muscle temperature in resting subjects exposed to a thermonetural (28°C) ambient environment. The working hypothesis was that the insulated skin under each disk would increase to some unknown steady state temperature which could be determined by comparing the steady state skin temperature under the disk with the actual muscle temperatures measured by a control probe which directly measured tissue temperature 0.8±0.2 cm, 1.3±0.2 cm, 1.8±0.2 cm, 2.3±0.2 cm, and 2.8±0.2 cm below the skin surface. Therefore, the temperature of the insulated skin alone could be used as an indicator of the muscle temperature at a specific depth below the skin. Eight subjects sat for 120 min while lateral thigh skin temperatures (measured 15.3 cm, 20.8 cm, and 26.3 cm superior to the patella) and vastus lateralis (lateral thigh) muscle temperature was measured by directly inserting a control muscle probe 20.5 cm superior to the patella. Vastus lateralis temperature was estimated non-invasively using two 5 cm diameter foam neoprene disks which were placed on top of the skin temperature probes (from time 60 to 120 min) located at 15.3 cm and 26.3 cm superior to the patella. The disks at the two locations were 3.2 mm (1/8”) and 4.8 mm (3/16”) thick, respectively. Rectal temperature was also measured during the entire exposure. The placement of the 3.2 mm and 4.8 mm disks on the thigh for a minimum of 15 and 20 min,
