Abstract： Objective To evaluate applicability of the newly developed ship-survival ration. Methods Six male volunteers were selected to only take 372 g newly developed ship-survival ration per day and drink 1500 ml purified water per day within 8 days. The subjective sensation symptoms during experiment were investigated. The indexes of physiology, biochemistry and physical ability were measured before and during experiment. Daily energy expenditure was calculated by life-activity-recording method. Results Body weight, blood glucose and physical work capacity ( PWC170) was reduced significantly while grasp force, body temperature,blood pressure and electrocardiogram(ECG)did not change significantly. The indexes of liver and kidney functions were within normal ranges. All but the strong sensation of starvation, subjective sensation of all volunteers at the end of experiment were good. Conclusions The newly developed ship-survival ration could basically meet eight day' s survival requirements of human.
