目的:观察某部官兵3km体能训练前后血尿酸(SUA)、肌酸激酶(CK)和肌酸激酶同工酶(CK-MB)水平变化。方法:选择参加年度体能训练的某部官兵483例,检测前均至少3个月未进行长跑训练。分别于训练前、训练后即刻、训练后6h、训练后24h、训练后48h,取静脉血测定其SUA、CK和CK-MB水平,分析其变化趋势及与年龄、性别、体重的关系。结果:3km体能训练后即刻,SUA水平非常显著高于训练前(P<0.01);训练后即刻及训练后6h、24h,血CK水平显著或非常显著高于训练前(P<0.05,P<0.01);训练后即刻及训练后6h,血CK-MB水平显著或非常显著高于训练前(P<0.05,P<0.01),年龄、性别、体重亦是重要影响因素。结论:年度首次3km长跑体能训练对血SUA、CK和CK-MB水平有显著影响,应注意及时充分休息,避免引起肾、骨骼肌及心肌的持续损害。 Objective: To observe the change of serum uric acid (SUA), creatine kinase (CK) and creatine kinase MB (CK-MB) before and after physical training of 3 km officers and men. Methods: A total of 483 officers and men who participated in annual physical training were selected. At least 3 months before the test, no long distance training was conducted. The levels of SUA, CK and CK-MB were measured before venous blood, before training, 6h after training, 24h after training and 48h after training respectively. The relationship between SUA, CK and CK-MB levels and their relationship with age, sex and weight were analyzed. Results: Immediately after physical training, the level of SUA was significantly higher than that before training (P <0.01). The levels of serum CK were significantly higher at 6h and 24h after training than those before training (P <0.05, P < 0.01). Immediately after training and 6h after training, blood CK-MB level was significantly or very significantly higher than before training (P <0.05, P <0.01), and age, sex and weight were also significant factors. Conclusion: The first 3km long-distance fitness training in the year has a significant effect on blood levels of SUA, CK and CK-MB. It should be noted that adequate rest should be taken in time to avoid sustained damage to the kidney, skeletal muscle and myocardium.
