坑道操对坑道作业人员反应时昼夜节律及调整的研究

摘要

Based on the theory of the modern chronobiology,the authorwapplied single cosine analysis to the statistics and biorhythm analysis,observed tunnel operator circadian rhythm of reaction time in the normal system of work and rest and inverted light-dark cycle in the tunnel environment and the effect of the tunnel gymnastics.The reaction time has a distinguished circadian rhythm under the condition of normal system of work and rest（P0.05）.The reaction time of tunnel gymnastics group takes on distinguished circadian rhythm under condition of inverted light-dark cycle（P0.05）,but control group didn′t have circadian rhythm.Tunnel gymnastics has obvious adjustment effect on reaction time.%以现代时间生物学理论为指导,应用单个余弦法进行生物节律分析和数据统计,观察在坑道环境中,正常作息制和光暗倒相制下坑道作业人员反应时的昼夜节律相位情况,以及坑道操对反应时节律的相位影响特点及规律。结果表明在正常作息制条件下,反应时表现明显的昼夜节律（P〈0.05）。在光暗倒相状态下,坑道操组表现明显的昼夜节律（P〈0.05）,而对照组不具有明显的昼夜节律。坑道操对反应时具有明显的调节作用。
