Norwegian military field exercises in the arctic: cognitive and physical performance.

摘要: In an effort to determine whether or not field living conditions degrade performance during cold weather military training, of 17 Norwegian Army soldiers in tents the (FG) was compared with that 13 barracks (GG). FG and GG performed similar tasks were equipped clothed identically. Each subject tested prior following 9 days training. The tests consisted marksmanship (score for a 5-shot group), snowshoe running (time cover 1700 m), anaerobic power (Wingate test), on 5 cognitive (preferred hand tapping, 4-choice reaction time, pattern recognition, memory search, code substitution; each test scored as % correct # completed). A subset subjects from group wore watches which recorded heart rate day. During training had lower average than FG, indicating physical activity level. Significant changes found rifle shooting mean power. (p less .001) time .001; pre vs. post) differences but significant interaction found. Among tests, by responses only Memory Search task, represented decrease while maintained. Time completed .002) Pattern Recognition suggesting incomplete learning no interactions Language: en
