【摘要】 目的:通过对体育学院游泳队运动员一些功能指标测试和教学观察对训练负荷的安排进行科学指导。方法:运动员每天早晨醒来利用晨脉表记录晨脉和个体主观疲劳,记录运动心率是在训练课中,一组训练内容结束后的即刻脉搏和休息2min后的恢复脉搏。肌酸肌酶和血尿素氮都是在每周一早晨抽血5mL进行检测,检测仪器为美国产MD-100半自动生化仪。教学观察主要是观察和询问运动员的一些表征,如自主疲劳、情绪、睡眠、食欲、眼神等。结果:发现运动功能水平下降时,游泳运动员的晨脉一般超过5次,早晨肌酸肌酶值平均超过7500nkat/L,血尿素值平均在8.5mol/L以上,训练时的运动心率恢复值小于是20%,入睡慢,食欲差,运动员自主疲劳感在数量级17左右。结论:晨脉、运动心率、肌酸肌酶值和尿素氮值在功能正常与下降时其指标值有显著差异,可以作为训练负荷安排的依据。更多还原

【Abstract】 AIM:To instruct the training load arrangement scientifically according to test of some functional indexes and teaching observation of swimming athletes in college of physical education. METHODS: The indexes of the swimming athletes were recorded, including morning rate and individual subjective fatigue with morning rate timer after wake-up every morning; instant pulse after a group of training and the recovery pulse after rest for 2 minutes during training class. Creatine kinase(CK) and blood urea nitrogen (BUN) were detected in the blood sample(5 mL) collected every Monday morning with the American MD-100 semi-automatic biochemical machine. The manifestations of the swimming athletes, such as self-determined fatigue, emotion, sleeping, appetite and eye expression, were observed and inquired during teaching observation. RESULTS: When the level of motor function descended, the morning rate exceeded 5 times, the average value of CK and BUN exceeded 7 500 nkat/L and 8.5 mol/L respectively, the recovery value of heart rate during exercise was less than 20%, slowly fell asleep and appetite was poor, and the level of self-determined fatigue was about 17. CONCLUSION: Morning pulse, heart rate after exercise, CK and BUN are significantly different when the motor function is normal and decreased, so they can be taken as the evidence for the arrangement of training load.更多还原
