Study on Physical Strength Reserves of Diver after Underwater Delivery

Abstract

Objective: This paper aims on the physical strength reserves of diver after long time underwater delivery, to find the reasonable underwater working time which can maintain diver's work ability. Method: Select 16 divers for underwater deliver experiment for different length of time, and carry out PWC170 measurement analysis. Result: After 2.5 hours underwater delivery, the diver still has a certain level of physical strength reserves. But after 3 hours underwater delivery, the physical strength reserves close to zero. Conclusion: Through the experiment, we conclude that the reasonable underwater delivery time is 2.5 hours, which can maintain diver's work ability.
