The purpose of the study was to investigate the short-term detraining effect on insulin sensitivity and glucose tolerance in young tennis players. 27 young tennis players (age 16.5 yrs) with regular tennis training participated this study. We measured serum blood glucose levels under glucose challenge condition, and compared them during the training state and 10-d after cessation of the training. Blood creatine kinase and uric acid levels were used as markers for the removal of the training. Blood lipids including triglyceride and cholesterol levels were also measured under the two different conditions. The short-term detraining in tennis players did not affect glucose tolerance, but fasting glucose level was slightly elevated (P＜0.05). Insulin level under glucose challenge condition was significantly elevated after 10-d detraining. The blood triglyceride and cholesterol levels were not changed after the 10-d detraining. The current study demonstrated that only 10-d detraining significantly reduced insulin sensitivity, as we observed that greater insulin level is required for sustaining normal glucose disposal. However, the blood lipid appears to be unaffected by the short period of detraining.
