Twenty CUBA male athletes were divided into 4 groups： group A （supplementation of Cr alone）, group B （supplementation of oligosaccharide）, group C （supplementation of oligosaccharide and Cr） and group D （placebo control group）. By using orthogonal L4 table （2a ）, the experiment was performed. There were factors including oligosaccharide （carbohydrate, CHO）, Cr and their correlation. Each factor had two levels： supplementation and no-supplementation. The results showed that the supplementation of CliO or Cr alone, combined supplementation of CHO and Cr could significantly reduce the glucose, urea nitrogen levels in blood and serum CK activity after competition in the athletes. Moreover, the effects of combined supplementation of CHO and Cr were more satisfactory. It was concluded that supplementation of CliO and Cr could promote the recovery of physical performance and athletic abilities after athletics in basketball athletes.展开更多

The results showed that after intensive training for one week, serum CK levels were significantly increased by 57.53 mmol/L （P〈0.05）. After regulation of the training intensity, average serum CK levels were increased by 21.79 mmol/L （P〈0.05）. BUN contents were increased by 0.83 mmol/L on average with the difference being not significant （P〉0.05）. After intermittent training, there was significant difference in the average increased levels of serum CK in athletes （P〈0.05）. There was significant difference before and after regulation of training （P〈0.05）. The increased levels of BUN were 0.78 mmol/L without significant difference （P〉0.05）. It was concluded that serum CK was one of the biochemical indicators monitoring the training load sensitivity of badminton athletes, but BUN was of little value in monitoring the training load. Both serum CK and BUN recovered slowly after one-week intensive training and intermittent training, suggesting the metabolic mechanism of human body in training needs further study.展开更多
