目的观察经红光照射后战士在运动后肺功能的影响。方法2007-03～2007-04,对20名健康的战士进行红光照射,照射1次/d,照射时间为0.5h/次,在照射前、照射1周和2周后分别进行长跑运动前后的肺通气功能测试及采静脉血测定生理指标:白细胞计数(WBC)、红细胞计数(RBC)、血红蛋白(Hb)、丙氨酸氨基转移酶(ALT)、门冬氨酸转移酶(AST)、肌酸激酶同功酶(CK-MB)。结果运动前红光照射2周后的肺活量(VC)、最大通气量(MVV)、用力呼气1s量(FEV1)、用力呼气1s率(FEV1%)及中期流速(MMF)与照射前相比都有明显增加(P<0.05,P<0.01)。运动后FEV1%和MMF在照射2周与照射前相比有明显增加(P<0.05)。照射1周后的Hb、照射2周后的RBC与照射前相比都有明显增加(P<0.05);照射2周后的Hb有显著增加(P<0.01)。生化指标中各种酶均下降,其中CK-MB值下降显著(P<0.05)。结论红光能促进机体在运动时维持身体的正常机能,延缓运动疲劳的发生,提高运动耐力。
Objective To observe the effect of warrior on lung function after exercise by red light. Methods From 2007-03 to 2007-04, 20 healthy soldiers were irradiated with red light for 1 time per day for 0.5 hours. Before and after the irradiation, 1 week and 2 weeks before and after the long-distance exercise The lung function tests and the venous blood samples were taken for measurement of physiological indicators: WBC, RBC, Hb, ALT, AST, Creatine kinase isoenzyme (CK-MB). Results The vital capacity (VC), maximum ventilation (MVV), forced expiratory 1s (FEV1), forced expiratory 1s rate (FEV1%) and mid-term flow rate (P <0.05, P <0.01). After exercise, FEV1% and MMF increased significantly (P <0.05) compared with that before irradiation at 2 weeks. After 1 week of irradiation, the RBC in both groups increased significantly (P <0.05), and increased significantly after 2 weeks of irradiation (P <0.01). Various biochemical indicators of enzymes decreased, including CK-MB decreased significantly (P <0.05). Conclusion Red light can promote the body to maintain the normal function of the body during exercise, delay the occurrence of exercise-induced fatigue and improve exercise tolerance.
