目的：评估第三军医大学营养与食品安全研究中心研制的特种抗疲劳食品军体Ⅰ号、Ⅱ号、Ⅲ号和Ⅳ号对士兵军事体力作业能力的作用。方法选取某边防部队54名士兵为受试者，以最大摄氧量为分组依据，随机分为对照组、受试1组和2组，每组均为18人。对照组为空白对照，受试1组和2组分别给予1号营养保障包（含军体Ⅰ、Ⅲ、Ⅳ号）和2号营养保障包（含军体Ⅱ、Ⅲ、Ⅳ号），连续干预7 d，干预期间维持正常作训。干预结束后，疲劳负荷后进行递增负荷试验测定体能，测试期间连续监测心率、询问主观疲劳感觉并记录力竭时间和达到75％最大心率时间；测试结束后立即检测血糖、乳酸、血尿素氮（ BUN）、血乳酸脱氢酶（ LDH）和肌酸激酶（ CK）；于当晚和次日早晨分别填写疲劳恢复量表，并测定乳酸值。结果受试1组和2组在递增负荷试验中力竭时间和达到75％最大心率时间明显延长，且力竭试验第6分钟时主观感觉评分也较对照组高；同时，递增负荷试验后受试1组和2组血糖浓度显著高于对照组，而血乳酸、BUN、LDH和CK含量较对照组低。递增负荷试验结束后，受试1组和2组血乳酸含量在当日晚即恢复正常，在次日清晨其含量也显著低于对照组；疲劳恢复主观感觉评分在两个时间点均较对照组高。受试1组和2组间上述各项指标差异无显著性。结论该中心研制的特种抗疲劳食品通过组合使用所形成的1号和2号营养保障包，可显著提高军人军事体力作业能力、延缓体力疲劳产生，同时可促进体能恢复、预防军事作训损伤，但两种营养保障包的作用差异无显著性。

Objective To assess the series of special anti-fatigue foods including JuntiⅠ, JuntiⅡ, JuntiⅢ, and Jun-tiⅣon military physical performance capacity .Methods Fifty-four soldiers , selected from a border defense troop , were randomly designated to control group , trial group 1 and trial group 2.Subjects of two trial groups were supplied with No .1 nutritional package ( including JuntiⅠ, Ⅲand Ⅳ) and No.2 nutritional package ( including Junti Ⅱ, Ⅲand Ⅳ),re-spectively, while no additional nutritional supplements were added in control group .After 7 days’ supplementation, a hard military exercise was performed to induce fatigue and an increasing load test was used to assess physical activity .RPE scale, exhaustive time and time taken to reach the 75% maximal heart rate were recorded while serum markers , such as glucose, lactate, BUN, LDH,and CK, were detected after test .Moreover, serum lactate and fatigue recovery scale were determined on the evening of the same day and the next morning .Results Prolonged exhaustive time and time taken to reach the 75%maximal heart rate and elevated RPE scores at 6 min were detected in both two trial groups compared with the control group .Meanwhile , after the increasing load test , elevated glucose concentration and reduced lactate , BUN, LDH and CK were also observed in both trial groups .Moreover, serum lactate of both trial groups was quickly recovered on the evening of the same day compared with the control group , and the next morning , serum lactate was even much lower in trial groups than in control group .The fatigue recovery scores were higher in trial groups at both time points .Meanwhile, there was no difference of such indexes between the two trial groups .Conclusion Through the combination use , the series of special anti-fatigue foods, inclucling No.1 and No.2 nutritional packages , can significantly improve the soldiers′physi-cal performance capacity , delay the physical fatigue emergence , promote physical activity recovery and prevent military training injury.
