Abstract

Training arrangements in a large and complex system of special research, game week (7 days before), is a very important part of it for the direct preparation and final adjustments, is for athletes training in various aspects of the best competitive state athletes adjust and restore the body's state of the critical period, through science, has targeted before adjustments can make a team physical, mental state, the basis of ability have been improved, the training effect a direct impact on the athletes. However, the domestic part of the high level of taekwondo athletes lack the scientific, effective and targeted before state adjustments and monitoring, research reports are rarely seen, it is difficult to provide effective reference for this important training phase. The eight-day follow-up study, the study of the People's Liberation Army is about to participate in the national championship taekwondo team of 12 outstanding women's taekwondo athletes through the continuous acquisition of physiological and biochemical indexes, to evaluate the real lesson athletes stimulation, specimens from competition period physiological, psychological, physical indicators to evaluate, to make the diagnosis and evaluation of athletes before the state, and analysis after the game fatigue characteristics, combined with the test results achieved by athletes in this competition, to conduct a comprehensive and objective analysis on the successful experience of the training work or insufficient to provide a reference for scientific training. The results are as follows: (1) athletes after the previous stage of the load strength training and frequent high-intensity combat training, part of the functional index were higher or lower than normal (physiological range) level, such as serum lactate dehydrogenase (LDH) serum creatine kinase (CK), elevated serum aspartate aminotransferase (AST), serum testosterone / cortisol (T / C ratio) at a low level, which mainly serum cortisol (C) value is high, suggesting that the previous stage of training intensity and the degree of opposition movements of the body caused by the accumulation of a greater degree of fatigue. CK, LDH and AST adjust the training in the week before falling back to the normal range; T / C also significantly increased, hemoglobin (Hb) increased significantly. Therefore, the reaction of the athletes training load change is more sensitive to the body's state of recovery significantly. (2) athletes physical and chemical indicators before and after the combat training with greater volatility in combat immediately after the heart rate (HR) and blood lactate (BLA) increased significantly, and the recovery faster, suggesting that the stability of the physical condition of athletes. (3) before the physiological, psychological and the special physical indicators compared to baseline values ??have increased, increased heart rate, 10 seconds, the number of single and double leg kick target, significantly shorter reaction prompted athletes before the body should better match state . (4) taekwondo competition may be caused by the fatigue of the central nervous system to the athletes. Stats show that after the match the special reduced ability to respond to, and affected by the stimulus should race, physical performance has actually strengthened. The fatigue occurrence characteristics may prompt Tae Kwon Do with the central fatigue.
