摘要

目的：本研究欲探討長跑選手停止訓練兩個月對葡萄糖耐受度、胰島素敏感性及自主神經系統的影響。方法：徵召14位長跑選手、14位規律運動者、14位無規律運動者分為三組。長跑選手進行兩個月的停止訓練後，將三組受試者進行口服葡萄糖耐受度測驗及自主神經系統測驗。結果：長跑選手在停止兩個月訓練後，口服葡萄糖耐受度測驗60分鐘至120分鐘血糖高於規律運動組（第60分鐘血糖值：停止訓練組126.24±4.96mg/dl>規律運動組107.36±5.61 mg/dl；第90分鐘血糖值：停止訓練組117.07±4.29 mg/dl>規律運動組100.43±3.72 mg/dl；第120分鐘血糖值：停止訓練組108.71±4.01 mg/dl>規律運動組88.36±4.81 mg/dl），停止訓練組的胰島素在第0分鐘顯著高於規律運動組（停止訓練組12.76±3.60 mIU/dl>規律運動組0.83±0.49 mIU/dl），在第120分鐘高於無規律運動組與規律運動組（停止訓練組28.98±9.25 mIU/dl>規律運動組10.20±1.64 mIU/dl；停止訓練組28.98±9.25 mIU/dl>無規律運動組9.14±1.28 mIU/dl），停止訓練組的HOMA值高於規律運動組與無規律運動組（停止訓練組2.86±0.89>規律運動組1.04±0.11；停止訓練組2.86±0.89>無規律運動組1.30±0.10），交感與副交感神經三組皆無顯著差異，空腹血糖及胰島素與副交感神經成負相關。結論：長跑選手經過兩個月停止訓練血糖控制能力、胰島素敏感性及副交感神經活性可能都退化至和無規律運動習慣的平常人一樣。

Purpose: This study was aimed to examine the effect of two months detraining on glucose tolerance, insulin sensitivity and autonomic nerves system in long distance runners. Methods: Forty two subjects were recruited for this study and divided as, long distance runners (detrained two months, DT, n=14), regular exercisers (E, n=14), and sedentary (C, n=14). All the subjects were performed oral glucose tolerance test (OGTT) and autonomic nerves system tests. Results: The decrease in glucose tolerance was more in the detrained group than regular exercise group [60 min blood glucose: DT (126.24±4.96 mg/dl) ＞ E (107.36±5.61 mg/dl); 90 min blood glucose: DT (117.07±4.29 mg/dl) ＞ E (100.43±3.72 mg/dl); 120 min blood glucose: DT (108.71±4.01 mg/dl) ＞ E (88.36±4.81 mg/dl)]. Insulin sensitivity was also decreased more in the detrained group than regular exercise and sedentary groups [(0 min serum insulin: DT (12.76±3.60 mIU/dl) ＞ E (0.83±0.49 mIU/dl); 120 min serum insulin: DT (28.98±9.25 mIU/dl) ＞ E (10.20±1.64 mIU/dl) ＞ C (9.14±1.28 mIU/dl)]. In addition, HOMA values were higher in the detrained group compared to sedentary and regular exercise groups (DT: 2.86±0.89＞ C: 1.30±0.10＞ E: 1.04±0.11). However, we found no significant difference in sympathetic and parasympathetic systems in all the groups. Fasting blood glucose level and serum insulin concentration showed negative correlation with parasympathetic activity. Conclusion: These results indicated that two months detraining could decrease the training effect to normal on oral glucose tolerance, insulin sensitivity and parasympathetic activity.
