Background:To discuss the relationship between exercise-caused fatigue called kidney qi deficiency and change rules of part of blood biochemical indexes.
Methods:Taking eighty rowing and canoeing athletes of Zhejiang province of China as research subjects in high intensity training before competition. All subjects firstly divided to
two groups of male and female. Then, in each gender group, there are three kind of group including kidney Yang deficiency, kidney Yin deficiency and control. In the control group, twenty-one athletes
comprising nine males and twelve females who only took low intensity training of adaptive training were included. In the kidney Yang deficiency group, there are twelve athletes comprised of seven male
and five female. In the kidney Yin deficiency group, there are seven athletes with four male and three female. There were significantly not any difference of age, height, weight and professional
training years among three groups. No western medicine or traditional Chinese medicine aiming at improving performance or anti-fatigue was used during research. After preliminary screening, forty
athletes were concluded in the final experiment. Basic methods including questionnaire investigation and exercise-caused fatigue mode construction were applied. Clinical manifestation of
exercise-caused kidney qi deficiency syndromes of traditional Chinese medicine and blood biochemical indexes including blood uria nitrogen (BUN), serum creatinine (Scr), serum testosterone (T) were
collected to investigate the relationship between exercise-caused fatigue called kidney qi deficiency and change rules of part of blood biochemical indexes after large intensity training of
pre-competition. Test data were processed through SPSS 15.0 and showed as Mean±SD. In each gender, χ2 test were applied among the three groups and p < 0.05 was taken as threshold of significantly
Results: After pre-competition high intensity training, nineteen athletes showed kidney qi deficiency syndrome, including eleven female and eight female, which formed 23.8% of all
subjects. Both male and female kidney Yin deficiency group showed significantly higher BUN level. For serum testosterone level, gender differences existed between two groups and control group. For
female, both groups showed significantly higher level than control group. Moreover, the level of Kidney Yang group was higher than Kidney Yin deficiency group. For male, both groups showed lower level
than control group and Kidney Yang deficiency group was a little lower than Kidney Yin deficiency group.
Conclusions:This research showed 23.8% kidney qi deficiency syndrome after pre-competition high intensity training. Sex factors should be considered in this research, both BUN and T
level can supply objective basis for microcosmic syndrome differentiation of character of Yin and Yan for kidney Qi deficiency syndrome of exercise-caused fatigue. Furthermore, it might support for
giving athletes nutrition programme and Chinese medicinal formulae suggestions for kidney Qi deficiency syndrome of exercise-caused fatigue.
