摘要
目的:研究生理节律和日常活动分别对人体疲劳程度的影响大小。方法:选取某校7名大学生志愿者,在军训期间对每日军训科目严格限制条件下进行该实验,以闪光临界融合频率、心率变异性、反应时、静态姿势图TLX-NASA量表评分作为指标,对每天分别在训练前和训练后疲劳程度的大小进行测量,以这些指标描述训练前后的疲劳程度。结果:反应时降低(0.60±0.09)、反应正确率提高(0.97±0.03);闪光临界光融合频率升高(40.84±2.14);心率变异性TP(3076.60±382.08)降低、心率变异性SDNN(55.28±16.85)降低;静态姿势图晃动减少,中低频率段(0.15±0.01)、前后方向重心变位(7.92±0.63),TLX-NASA量表评分降低(30.47±10.23)。以上差异均具有统计学意义(P<0.05)。结论:生理节律相对于日常活动对机体的疲劳状态有更大的影响。
Objective： To compare the effect of circadian rhythm and daily life to the status of fatigue. Methods： 7 volunteers from the campus were included in this study. In the period of military training, all the quantity of training classes were restricted strictly every-day. We use the following parameter as testing indexes： critical fuse frequency （CFF）, heart rate variability （HRV）, reaction time（RT）, posturography and TLX-NASA assessment. In the analysis, we compared the indexes pre-training and post-training which measured the status of fatigue. Results： Compared with the results pre-training, CFF （40.84±2.14） increasing, in the HRV indexes, TP （3076.60± 382.08） decreasing, SDNN（55.28±16.85） decreasing, RT（0.60±0.09）decreasing, correct ratio of RT（0.97±0.03）increasing, the sway of posturography decreasing, middle-lower fIequency（0.15±0.01 ）decreasing, sway of anterior-rear direction（7.92± 0.63）decreasing, and TLX-NASA assessment （30.47±10.23） decreased. These comparisons had significant difference. Conclusion： Circadian rhythm has more effect than daily life to the status of fatigue.
