目的：观察抗疲劳制剂对战士体力耐力的影响．方法：以某部新兵营战士为观察对象．在实验期间实验组（６０人）和对照组（３０人）于每日午餐、晚餐后分别服４００ｍｌ抗疲劳制剂和安慰剂，连续服用１４ｄ，于实验前后测试血乳酸（ＬＡ），最大摄氧量（ＶＯ２ｍａｘ）和心功能指数（ＨＩ）．结果：实验前战士３０００ｍ跑后血ＬＡ水平显著升高［（１２．０５±４．２７）ｍｍｏｌ／Ｌ］，服制剂１４ｄ后血ＬＡ［（８．４３±３．１７）ｍｍｏｌ／Ｌ］下降了３０％，与实验前比较差别非常显著（Ｐ＜０．０１），与对照组［（１０．４９±１．８４）ｍｏｌ／Ｌ］亦有显著差别（Ｐ＜０．０５）．实验组服制剂１４ｄ后ＶＯ２ｍａｘ达（５５．９１±３．１７）ｍｌ／（ｋｇ·ｍｉｎ），与实验前（５２．２８±３．６４）ｍｌ／（ｋｇ·ｍｉｎ）及与对照组（５２．０６±３．７１）ｍｌ／（ｋｇ·ｍｉｎ）比较均有非常显著差别（Ｐ＜０．０１）．ＨＩ达５．３０±２．０７，与实验前（８．０２±２．３１）和对照组（６．９３±２．０）比较均有非常显著差别．结论：血ＬＡ是评价耐力素质最有效的指标，ＶＯ２ｍａｘ和ＨＩ能较好地反映有氧代谢能力和心肺功能状态，是评价体力耐力的重要指标．抗疲劳制剂具有?
Objective: To observe the effect of anti-fatigue preparation on physical endurance of soldiers. Methods: Take a certain recruits camp soldiers as the observation object. During the experiment period, the experimental group (60 persons) and the control group (30 persons) took 400ml anti-fatigue preparation and placebo respectively after daily lunch and dinner for 14 days continuously. Before and after the experiment, blood lactate (LA), maximal oxygen uptake Volume (VO2max) and cardiac function index (HI). Results: The level of blood LA was significantly increased after 3000 m in the former soldiers [(12.05 ± 4.27) mmol / L], and the blood LA [(8.43 ± 3.17) mmol / L] (P <0.01). Compared with the control group [(10.49 ± 1.84) mol / L], there was also a significant difference (P <0.05). After 14 days, the VO2max in the experimental group was (55.91 ± 3.17) ml / (kg · min), which was significantly higher than that in the control group (52.28 ± 3.64) ml / (kg · min) .06 ± 3.71) ml / (kg · min), there was a significant difference (P <0.01). HI reached 5.30 ± 2.07, which was significantly different from that before the experiment (8.02 ± 2.31) and the control group (6.93 ± 2.0). Conclusion: Blood LA is the most effective index for evaluating endurance quality. VO2max and HI can better reflect aerobic metabolism and cardiopulmonary functional status, which is an important index to evaluate physical endurance. Anti-fatigue preparations have?
