摘　　要：目的了解陆军特战部队军人5公里武装越野训练的训练强度和疲劳程度,筛选可用于疲劳程度评价的敏感指标。方法采用简单随机抽样的方法,2018年5-6月从某特种作战部队选择20名特战专业岗位战士作为训练组,严格按照特战部队考核标准进行5公里全副武装越野训练,对训练前后各项疲劳程度相关指标进行比较分析;并采用整群抽样的方法选择456名特战专业岗位军人进行训练情况问卷调查,对不同特战训练科目疲劳程度进行量化评分和排序。结果①与5公里武装越野训练前的静息水平比较,训练后战士末梢血乳酸水平显著升高,唾液pH值显著降低(P<0.001,P=0.013)。②与训练前静息水平比较,训练后战士心率和血流灌注指数显著增加(P<0.001,P=0.015),血氧饱和度显著降低(P<0.001)。③训练后战士习惯手、非习惯手握力及皮肤空间两点阈与训练前静息水平相比差异无统计学意义。④训练后战士神经行为能力各指标中记忆扫描、视注意广度及曲线拟合能力指数值与训练前静息水平比较均显著降低(P=0.030,P=0.007,P=0.001)。⑤16项特战训练科目中疲劳程度高于5公里武装越野的有6项。结论 5公里武装越野训练为次重度劳动强度;血乳酸、唾液pH值、心率、血氧饱和度、视注意广度及曲线拟合能力指数等指标可作为评价特种作战部队军人训练疲劳程度的敏感指标。Objective To evaluate the training intensity and fatigue level after 5 km armed off-road training in army special operations forces(SOF), and to screen sensitive indicators for fatigue evaluation. Methods Twenty soldiers at professional posts were collected from a SOF unit during May and June 2018 by simple random sampling. They conducted a training of 5 km armed off-road strictly according to the assessment criteria of SOF. Their fatigue indexes were collected before and after training, and the results were compared and analyzed. A survey questionnaire about training conditions was conducted on 44 officers and 420 soldiers selected from a SOF unit by cluster sampling. The fatigue levels of different SOF training subjects was quantitatively scored and ranked. Results ①Compared with the resting values before 5 km armed off-road training, the peripheral blood level of lactic acid(P<0.001) was increased significantly, while the pH value of saliva was decreased obviously after training(P=0.013).② Their heart rate(P<0.001) and blood perfusion index(P=0.015) were elevated remarkably, but the oxygen saturation was reduced(P<0.001) after training.③No significant differences were found in the handgrip strengths of the dominant and non-dominant hands and skin space thresholds before and after the training.④The training reduced the indicators of neurobehavioral ability, such as memory scanning(P=0.030), visual attention span(P=0.007) and curve fitting ability index(P=0.001) in the subjects when compared with the data before training.⑤Among the 16 training subjects, there were 6 SOF training subjects causing higher fatigue level than that of 5 km armed off-road training. Conclusion Five-kilometer armed off-road training is an activity of sub-severe intensity. Blood lactic acid, saliva pH value, heart rate, oxygen saturation, visual attention span, and curve fitting ability index can be used as sensitive indicators to evaluate the training fatigue of soldiers in SOF.
