Some simple and non-invasive methods are applied to test the physical conditions of athletes and their adaptability to training load. It is necessary to prevent overfatigue in order to improve the training quality of athletes. The experiment took place during a winter training period (two months before the Indoor Athletics Championships). Four 400m elite runners were subject to systematic functional monitoring. The indices of the monitoring include urinary norepinephrine, simple questionnaire, EEG, quantitative load test and muscle strength test. The authors try to evaluate athletes' functional conditions comprehensively through the changes of nervous system, cardiovascular system, endocrine system, muscle system and psychology. The monitoring in daily training should be non-invasive and simple. The problems should be found out in time. The information should be fed back timely. And the suggestions should be put forward and solved as soon as possible. The result proves the following: 1. Urinary norepinephrine is a good monitoring index for training adaptation. The more decrease of norepinephrine in recovery period, the better of the athlete's adaptation to the training load in previous stage. So the training load might be increased in the following training. On the other hand, athlete is not adaptable to the previous training load if the norepinephrine increases obviously. Therefore the training load should be decreased in the following training and the recovery period should be prolonged. 2. The simple questionnaire reflects athlete's functional state from the aspects of nervous system, muscle system and psychological state. Its value can be used as a simple index for monitoring athlete's daily fatigue. 3. The comprehensive evaluation of urinary norepinephrine, simple questionnaire value, EEG, quantitative load test and muscle strength test may better reflect athlete's functional state all-sidedly and help prevent overfatigue. |
