| 摘要: |
| 目的 探讨大深度氦氧饱和潜水过程中,心率(heart rate, HR)与自觉疲劳分级(rating of perceived exertion, RPE)在潜水员机体疲劳监测中的作用。方法 采用500 m饱和潜水系统模拟水下100 m压力环境:压力为1.1 MPa;氧分压为35~52 kPa;二氧化碳分压<0.5 kPa;高压暴露期间温度为(31.0±1.7)℃;相对湿度为(76.8±3.5)%。呼吸气体为氦氧混合气。选取6个时段检测18名潜水员的HR与RPE值,包括:(1)入舱前1天;(2)到达100 m稳压第1天;(3)100 m运动负荷至峰值;(4)100 m稳压第2天;(5)出舱后第1天;(6)出舱后第7天。所得数据采用SPSS 17.0进行统计学配对t检验及相关性分析。结果 从入舱前1天至到达100 m稳压第1天,HR下降并具有统计学意义(P<0.05);从出舱后第1天至出舱后第7天,HR升高并具有统计学意义(P<0.05)。入舱后的基础RPE值与入舱前相比差异均有统计学意义(P<0.05)。在100 m稳压阶段的运动负荷试验中,HR与RPE变化呈一致性,且峰值时测得的数据与到达100 m稳压当天基础值相比差异有统计学意义(P<0.05)。潜水员RPE值与HR呈高度相关(r=0.734,P<0.01)。结论 HR和RPE可以作为潜水员大深度氦氧饱和潜水时机体疲劳监测指标。 |

| Abstract: |
| Objective To study the application of heart rate(HR) and rating of perceived exertion(RPE) scale in monitoring the physical fatigue in the divers during the 100 msw heliox saturation diving. Methods The 100 msw pressure environment was simulated by a 500 msw saturation diving system: pressure was 1.1 MPa; oxygen partial pressure was 35-52 kPa; carbon dioxide partial pressure was <0.5 kPa;the temperature during exposure to high pressure was (31.0±1.7)℃;and the relative humidity was (76.8±3.5)%. Respiratory gas was heliox. The 18 divers' HR and the scores of RPE scale were recorded at 6 time points, including (1)the day before the subjects entered the chamber; (2) the first day that the subjects were exposed to 100 msw pressure environment; (3) the peak of the subject physical exercise load test under 100 msw pressure environment; (4) the second day under 100 msw pressure environment; (5) the first day that the subjects were out of the chamber; and (6) the seventh day that the subjects were out of the chamber. All the data were analyzed with paired-samples t-test. The correlation was analyzed with Pearson correlation. Results From the day before the subjects entered the chamber to the first day that the subjects were exposed to 100 msw pressure environment, the resting HR of subjects was significantly decreased (P<0.05); From the first day that the subjects were out of the chamber to the seventh day that the subjects were out of the chamber, the resting HR was significantly increased (P<0.05). Significant differences were also found in the basic RPE score of the subjectes between before entering the chamber and after entering the chamber(P<0.05). During the 100 msw heliox saturation, with the variable physical work loads, the trend of of heart rate changes was still in accordance with the score of RPE scale, with that measured at the peak of the subject physical exercise load test under 100 msw pressure being significantly different from that measured at the first day the subjects were exposed to 100msw pressure (P<0.05).The RPE score was significantly related with the HR of divers (r=0.734, P<0.01). Conclusion The combined application of HR and RPE scale can monitor the physical fatigue of the divers during 100msw heliox saturation diving. |
