【摘要】：目的:观察昼夜生物节律对青年男子足球运动员运动能力和代谢反应的影响,为科学安排训练计划提供理论依据。方法:20名青年男子足球运动员分别于清晨(8:00)和傍晚(17:00)进行一次Yo-Yo实验(间隔36h),实验前、后测定口腔温度并取静脉血测定血浆生化指标(TC、HDL、TG、LDH、CK、Glu、UA和La),实验过程中采集心率(HR),实验后测定主观疲劳感觉(RPE),并记录Yo-Yo实验完成的总距离(运动能力)。结果:傍晚时Yo-Yo实验总距离和运动中的峰值心率(HR_(peak))均高于清晨(P0.05),运动后RPE则无显著性差异(P0.05)。与清晨比较,傍晚Yo-Yo实验前口腔温度、TC、HDL-c、TG、LDH、CK、Glu和UA均升高(P0.05),Yo-Yo实验后TC、HDL-c、TG、LDH、CK和Glu升高(P0.05),口腔温度和UA则无显著性差异(P0.05);与Yo-Yo实验前比较,Yo-Yo实验后口腔温度与各生化指标在清晨以及傍晚均显著性升高(P0.05)。结论:男子足球运动员专项运动能力在傍晚高于清晨,其机制可能与傍晚时体温升高,无氧代谢供能效率增加以及在相关代谢物质作用下形成的有利于调动机体生理机能的内环境有关。
[Abstract]:Objective: to observe the effect of circadian biological rhythm on sports ability and metabolic reaction of young male football players. Methods A Yo-Yo experiment was conducted by 20 young male footballers in the morning at 8: 00 in the morning and 17: 00 in the evening. After the oral temperature was measured and the venous blood was taken for the determination of plasma biochemical indexes, TCC HDLX, TGLDH, CKG, Glua, UA and Lahuo were collected in the course of the experiment. After the experiment, the subjective fatigue sensation was measured, and the total distance (motor ability) of Yo-Yo experiment was recorded. Results: in the evening, Yo-Yo was performed in the evening. The total distance of experiment and peak heart rate during exercise were higher than that of P0.05 in morning, but there was no significant difference in RPE after exercise. In the evening before Yo-Yo test, the oral temperature and the levels of Glu and UA were increased before Yo-Yo test. The oral temperature and UA showed no significant difference between Yo-Yo test and Yo-Yo test, but the oral temperature and UA showed no significant difference in the morning and evening, compared with those before Yo-Yo test, the oral temperature and biochemical indexes were significantly higher in the morning and in the evening than before the Yo-Yo test. Conclusion: the special sports ability of male football players is higher in the evening than in the early morning. The mechanism may be related to the increase of body temperature in the evening, the increase of energy supply efficiency of anaerobic metabolism, and the internal environment formed under the action of related metabolites, which is conducive to the mobilization of physiological functions of the body.
