It has been only a bit more than a decade since Sanda was taken as an event of Wushu contest sports. As a basis of athleticism which is no doubt the most prominent part in contest sports, athletic training plays an important role in it. With the rapid improvement in the recent-year athletic techniques, the speedy increase in the intensity of international competition and the rapid development of the worldwide science and technology, it has been widely and clearly recognized that the expected training effect is unattainable and winning in the violent present-day international sports competitions is unachievable, unless the research results of modern science and technology are widely applied to and guide the training. Therefore, no longer content with the old training style based on the experience from trainer to trainee, people turn to new theory, new idea, new science and technology, new equipment and instrument, and new techniques and means for the purpose of attaining greater and more rapid improvement in athletic abilities. The suitability of exercise load is an aspect of making sports training scientific. However, the scientific evaluation for exercise load remains a difficult problem which is badly needed solving. This thesis, guided by the methodology of national and social sciences, adopting a combined physiological and biochemical method, performs a tracking test to 12 athletes from the Sanda team of Shanghai Institute of Physical Education, and establishes a scientific monitoring and evaluating system for Sanda training in Wushu which has multi-indices and multi-stratifications, and is easily carried out. The purposes are: (1) seeking after a relatively valid set of physiological and biochemical indices for monitoring the amount and intensity of exercises in the Sanda training process and studies their changing rules; (2) searching for some biological features in Sanda, for providing a theoretical basis for evaluating the functional state of Sanda athletes; (3)supplying a scientific basis for trainers to establish and revise training programs. This thesis mainly studies some aspects of the Sanda training process , such as exercise amount, exercise intensity, and functional state of athletes, etc. The results are as followings: In terms of exercise amount, (1) we find out that blood urea nitrogen and ferrohemoglobin are feasible and valid indices to assess exercise amount of Sanda, and establish three kinds of equations for discriminant analysis:F1(small)=7.062*BUN+25.469*HGB-221.910; F2(medium)=7.583*BUN+23.725*HGB-1198.655; F3( large)=9.172*BUN+24.222* HGB-217.586, therefore, establish a basis for quantitative analysis and scientific judgment for exercise amount , and create favorable conditions for further studies concerned; (2) a large amount of exercises of Sanda athletes can cause remarkable changes in the indices of their creatine kinase in blood serum, lactate dehydrogenase, hydrocortisone and proportion of homosteron and hydrocortisone, etc. and these are sensitive indices for monitoring Sanda training. However, because of the large diversity, distinct individuality , and vague regularity of the elements causing these changes, they need further studying if they are used as objective indices to assess Sanda training . In terms of exercise intensity,(1)the better indices for monitoring the exercise intensity in Sanda training are lactic acid (La) indexes and serum lactic dehydrogenase indices,and then follow the creatine kinase (CK) indexes; (2) highly intensified training can apparently increase the activity of creatine kinase and lactate dehydrogenase in blood serum of the athletes, and further intensified training can increase more apparently the activity of their creatine kinase in blood serum; (3) highly intensified training can improve the homosteron in blood serum, meanwhile, luteinizing hormone and follicle stimulating hormone in blood serum are also apparently improved. As a result, the possible reason for the increase of homosteron in blood serum of the athletes is that more gonadotropic hormone is excreted by stimulating hypophysis, and hence strengthens the composition of homosteron in blood serum of the Sanda athletes; (4)as to the homosteron in blood serum of the athletes while in the state of quietness , that of the excellent group is apparently higher than the average group. In terms of functional state and athletic ability,(1) evaluated by aerobic work in physics, the aerobic capacity of Sanda athletes, after a period of training, can all reach a first-class criterion, and vary with different periods of training; (2)evaluated by the method of Wingate, after a period of training, the stamina of muscles which keep up working efficiently can be apparently lengthened and the amortization ability and cleaning speed of lactic acid are also enhanced; (3) as to the muscular capacity of the Sanda athletes to produce high mechanic function after a short period of training, and the muscular stamina to keep up functioning highly efficiently, those of the excellent group is apparently higher than the average group, which suggest that these are two valid indices to assess the ability of the athletes; which, on the other hand, also indicate Wingate Testing Method is a valid means to assess the ability of Sanda athletes; (4) by evaluating the biochemical indices, at the first assessment ,the whole mechanic function is in a good state; at he second assessment, the whole mechanic function tends to get worse, however, at the third assessment ,the whole mechanic function turns up again.(5) the biochemical indices for synthetically assessing the mechanic functional state of the Sanda athletes are blood urea nitrogen, ferrohemoglobin, creatine kinase, and proportion of testobase, and hydrocortisone; (6) assessed by constant amplitude muscle strength test, the training results of the Sanda athletes, after a period of training, are as follows: the back maximum moment is apparently shortened, the maximum strength of left knee extensor tends to increase, and the maximum strength tends to decrease; the moment of right knee extensor isapparently shortened , the maximum strength of left elbow flexor muscle is apparently increased, and the velocity strength of left elbow flexor muscle is also apparently increased; the maximum strength of right elbow flexor muscle is apparently increased, and the velocity strength of right elbow flexor muscle and the moment proportion of flexor muscle and extensor muscle are also increased. In addition, the analysis by the constant amplitude muscle strength test suggests that such indices are the valid ones to assess the abilities of the Santle athletes as the maximum strength moment of the back extensor muscle/ avoirdupois , back extensor muscle, flexor muscle, velocity strength moment/ avoirdupois, the maximum flexor muscle and extensor muscle. moment of left knee/ avoirdupois and flexor muscle moment , the maximum velocity strength moment of left knee flexor muscle/ avoirdupois, the maximum strength moment of right knee extensor muscle/ avoirdupois, the velocity strength moment of right knee extensor muscle/ avoirdupois, the velocity strength moment of right elbow extensor muscle/ avoirdupois, etc. Meanwhile, the analysis also shows that the ideal ratio of moments of flexor m. and extensor muscle is when velocity is 60°per second, back: about 90%; left knee: about 53%; right knee: about 50%; left elbow: 115%; right elbow: about 105% . When velocity is 180°per second, back: about 70%; left knee: about 52%; right knee: about 52%; left elbow: about 90%; right elbow: about 90%.
