摘要
目的:跟踪监测中国跤女运动员赛前训练期血液生理生化和流变学指标的变化及茶多糖干预效果。方法:中国跤女运动员20名,分为安慰剂组和茶多糖组,进行4周赛前训练,每天睡前1小时分别温开水冲服剂量为10 mg/kg体重的安慰剂和茶多糖,测试赛前训练前1天、第1、2、3、4周赛前训练结束时生理生化及血液流变性指标。结果:第1周赛前训练结束CK、LDH、AST、ALT、C及BV、PV、HRD、RCA、VR、TK、PAdT、PAgT明显上升,RBC、HCT、HB、T、T/C明显下降;第2周赛前训练结束时CK、LDH、AST、ALT、C及BV、PV、HRD、RCA、VR、TK、PAdT、PAgT开始回落,RBC、HCT、HB、T、T/C开始回升,并持续到第3、4周赛前训练结束时;安慰剂组第3、4周赛前训练结束时各指标保持相对稳定,周间差别不显著,各指标基本都差于赛前训练前,茶多糖组第3、4周赛前训练结束时各指标呈现良性发展趋势,周间差别显著,各指标基本都优于赛前训练前。结论:中国跤女运动员赛前训练期的身体机能状态与赛前训练前尚有差距,应注意营养和休息调整。茶多糖干预可促进赛前训练期RBC和HB合成;保护骨骼肌、心肌和肝脏免受损伤;改善机体代谢状态和血液流变性,促进和加快身体机能恢复。
Objective：To monitor female Chinese-style wrestling athletes’physiological,biochemi-cal and hemorheological indices and the effect of tea polysaccharide on their physical condition dur-ing pre-competition training. Methods：20 elite Chinese-style wrestling athletes were randomly se-lected and divided into placebo group and tea polysaccharide group. The two groups respectively took placebo and tea polysaccharide at a dose of 10 mg/kg body weight 1 h before going to bed every day during 4 weeks’pre-competition training. The physiological,biochemical and hemorheological indices were tested during pre-competition training. Results：The indices of CK,LDH,AST,ALT,C,BV,PV,HRD,RCA,VR,TK,PAdT and PAgT started to fall,the indices of RBC,HCT, HB,T and T/C started to rise,and the trend continued until the end of 3rd and 4th week’s pre-competition training. At the end of the 3rd and 4th week’s pre -competition training,placebo group’s indices remained relatively stable and were lower than those of before training,tea polysac-charide group’s indices showed a healthy development trend and were better than those before train-ing. Conclusions：Compared with their pre-competition training’s physical condition,female Chi-nese-style wrestling athletes’physical condition was poor during pre-competition training. They need to pay attention to nutrition and rest. Tea polysaccharide could promote the synthesis of RBC and HB,protect skeletal muscle,cardiac muscle and liver from damage and improve metabolism and blood rheology.
