Motor and Cognitive Performance Do Not Change during a Ten-Week Submarine Patrol.

摘要

Submariners experience many stresses and changes in their normal lifestyles while on patrol. These stresses may affect performance, vitamin levels, mood, and blood chemistry. This study investigated the effect of vitamin supplementation on performance in submariners before, during, and after a submarine patrol. While on patrol, half of the subjects were given a vitamin supplement while the other half received a placebo. There were no changes in performance on tests of motor performance, timed mental arithmetic, digit symbol substitution, or choice reaction time that could be attributed to either the vitamin supplement or to the patrol.
