Abstract
The purpose of the present study was to investigate the intramuscular temperature fluctuations in the human forearm immersed in water at 15C. Tissue temperature (T sub t) was continuously monitored by a calibrated multicouple probe during 3 h immersion of the forearm. The probe was implanted approximately 90 mm distal from the olecranon process along the ulnar ridge. T sub t was measured every 5mm, from the longitudinal axis of the forearm (determined from computed tomography scanning) to the skin surface. Along with T sub t rectal temperature, skin temperature and heat loss of the forearm were measured during the immersions. Five of the six subjects tested showed evidence of cyclic temperature fluctuations in the forearm limited to the muscle tissue. The first increase of the muscle temperature was observed 75 (SE 6) min after the onset of the immersion, and the duration of the cycle averaged 36 (SE 3) min. TRUNCATED
