Abstract:

The data presented here deals with the physiological and psychological responses of man 13 subjects to cold exposure 0 C and added stresses. The additional stresses included cold water 15 C-mid thigh, sleep deprivation 24 hr and exercise 70 maximum heart rate. Cardiovascular and respiratory parameters were monitored throughout the experiments. Urinary catecholamine excretion was determined to estimate stress levels. Skin and rectal temperatures were continuously monitored to evaluate temperature regulation. EMG monitoring was used to study the onset, pattern and magnitude of shivering in seven muscle groups. Four methods for short term shiver suppression were evaluated under the five experimental protocols. The CCAB was used to evaluate cognitive function and the F.A.T.S. system was employed to evaluate rifle shooting performance. Shooting performance and cognitive function were not significantly affected by additional stressors. Keywords Cold exposure Stress Shivering Suppression of shivering EMG Cognitive function Motor function Cold water Exercise RA 3.
