| 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 everyday.
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 frequency（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. |
