目的:观察低山带地区驻训士兵5000m耐力跑后血液生化指标的变化。方法:分别选择平原某部驻训士兵(平原组)及某低山带地区驻训士兵(低山带组)各32例,均于各自驻训地按照相关标准在23min内完成5000m耐力跑,分别在耐力跑当日凌晨、耐力跑后即刻及次日凌晨,采集肘静脉血2～3ml,检测血乳酸(PAP)、血氨(AMM)、尿素氮(BUN)、尿酸(URIC)、肌酐(BR)、乳酸脱氢酶(LDH)、谷丙转氨酶(ALT)、谷草转氨酶(AST)、C-反应蛋白(CRP)、肌酸激酶(CK)水平变化。结果:耐力跑后即刻,两组PAP、AMM、BUN、URIC、CRP、CK水平均较耐力跑当日凌晨显著或非常显著升高(P<0.05,P<0.01);次日凌晨,两组上述指标均显著下降,其中,低山带组PAP、BUN、URIC、CK水平显著低于同一时间节点平原组(P<0.05)。结论:低山带地区驻训更有利于大强度训练后血液生化指标的恢复。
Objective: To observe the changes of blood biochemical indexes after 5000m stamina run in soldiers stationed in the low mountain area. Methods: Thirty-two (32) units of soldiers (plain group) and some soldiers stationed in a certain low mountain region (plain group) were selected respectively. All of them were completed 5000m endurance running within 23min according to relevant standards in their respective training camps. Respectively in the early morning of endurance run, immediately after endurance run and the next morning, collecting elbow venous blood 2 ~ 3ml, detecting blood lactate (PAP), blood ammonia (AMM), blood urea nitrogen (BUN), uric acid (URIC) BR, LDH, ALT, AST, C-reactive protein (CRP) and creatine kinase (CK) were measured. Results: Immediately after endurance exercise, the levels of PAP, AMM, BUN, URIC, CRP and CK in both groups were significantly or very significantly higher than those in the early morning of endurance run (P <0.05, P <0.01) The indexes of PAP, BUN, URIC and CK in low mountain group were significantly lower than those in nodal plain group at the same time (P <0.05). Conclusion: Station training in low mountain areas is more conducive to the recovery of blood biochemical indexes after intensive training.
