The Research on before and after Training Biochemical Index of Sports College Students Majoring in Free Fight

four, once a week, through the experimental method, the University of Linyi Institute of Physical Education Majors of 26 Sanda test day horizontal base value and the actual training after 3min 1H, serum creatine enzyme CK, blood lactic acid, serum lactate dehydrogenase BLA LDH, hemoglobin (HB), blood urea (BU), serum biochemical indexes C, T of the serum testosterone cortisol were monitored and compared; results show: CK, BLA, Sanda athletes LDH, HB, BU, C, T based values were within the normal range of our ordinary men value, but slightly higher value of HB, BU, T, CK, BLA after the end of training, the value of BU first increased and then decreased, but BU decreased slightly after rising value; stable in a certain range of LDH and C; the HB value is decreased and then increased; T values showed increasing trend at first and then decreased. With the vigorous development of martial arts in the world, the movement technical level increasing, competition more intense, therefore, as an important means of Sanda scientific training, the changes of biochemical indexes of athletes after training on physical function of law research, and improve the level of scientific training, promote the athletic level, has important meaning.
