Background:This study monitored the body function level and the special technical training load of Chinese elite female judo athletes during the run-up to the world Judo Championships
in order to provide theoretical basis and reference for the preparation of Rio Olympics.
Methods:Six athletes were selected as subjects from Chinese national women's judo team. The national team has organized a 4 weeks systematic training before 2015 World Judo
Championship and trained 6 days per week, and rested on Sunday. On Monday morning of week-1 and week-4, athletes’ physical functione were evaluated by testing blood testosterone (T), cortisol (C),
blood urea (BU), creatine kinase (CK), white blood cell (WBC), red blood cell (RBC) and hemoglobin (Hb). Everyday’s special technical training course included warm up activity 40 min, technical combat
80 min, relaxation activity 30 min. We randomly picked one special technical training day of week-1 and week-4 respectively and tested blood CK, BUN and urine protein (PRO) before and after training,
and in next morning to evaluate the load intensity and volume of that special technical training day.
Results:In week-4, when compared with indexes of week-1, CK decreased significantly (86.7+/-24.3 U/L vs. 166.2+/-75.4U/L, p<0.05); RBC and HB increased significantly
(4.5+/-0.3*10E12/L vs. 4.4+/-0.3*10E12/L, 137.0+/-8.3g/L vs. 131.8+/-7.4g/L, p<0.05). And other indicators did not change significantly (p>0.05). In the next morning after special technical training
of week-1, CK did not change significantly when compared with CK after training(350.3+/-154.1U/L vs. 430.7+/-153.3U/L, p>0.05), BU and PRO decreased significantly when compared with that after
training (6.8+/-0.8 mmol/L vs. 7.7+/-0.9 mmol/L, 17.5+/-6.1 mg/dl vs. 76.7+/-36.1 mg/dl, p<0.05). In the next morning after special technical training of week-4, PRO did not change significantly when
compared with that after training (10.0+/-7.7 mg/dl vs. 39.2+/-30.4 mg/dl, p>0.05), CK and BU decreased significantly when compared with that after training (109.3+/-23.8 U/L vs. 206.2+/-88.5 U/L,
5.4+/-1.0 mmol/L vs. 7.3+/-0.5 mmol/L, p<0.05). After special technical training, CK and PRO in week-4 were significantly lower than that in week-1 (206.2+/-88.5U/L vs. 430.7+/-153.3 U/L, 39.2+/-30.4
mg/dl vs. 76.7+/-36.1mg/dl p<0.05), while BU showed no statistical significance (7.3+/-0.5 mmol/L vs.7.7+/-0.9 mmol/L p>0.05).
Conclusions:The level of physical function of Chinese elite female judo athletes was significantly improved by the training before the competition by increasing in muscle recovery and
body transport oxygen system. The adaptability of athletes on training load intensity was enhanced in the last week before competition, which was related to the level of physical function. It is
recommended to increase the load intensity in the later period of training to meet the demand of the competition.
