停止運動訓練會增加肥胖程度和降低血糖控制能力及血液中睪固酮濃度，本研究目的欲探討不同肥胖程度對停止訓練後的肥胖程度、血糖控制能力及血液中睪固酮濃度的影響。募集身體質量指數在正常範圍及肥胖的優秀選手各十位，測量身高、體重、腰圍、臀圍、總熱量攝取及血液中睪固酮濃度，進行口服葡萄糖耐受度測驗及胰島素敏感性測驗。本研究之結果：正常組運動員胰島素敏感性及血液中睪固酮濃度高於肥胖組運動員，但正常組運動員在停止訓練後增加肥胖程度和降低血糖控制能力及血液中睪固酮濃度，而肥胖組運動員停止訓練後肥胖程度、總熱量攝取和血液三酸甘油酯濃度－增加的程度高於正常組運動員。本研究之結論：肥胖運動員在停止訓練後會更快速的增加肥胖程度、總熱量攝取及三酸甘油酯濃度。基因遺傳造成個體間肥胖程度不同，肥胖運動員在退休後更需要規律性運動來抑制肥胖對健康的影響。

Detraining is known to increase the obese degree, decrease homeostasis of blood glucose and testosterone concentration. This study was aimed to examine the effect of detraining on obese degree, blood glucose levels and testosterone concentration in athletes with different BMI values. Twenty male players consisted of 2 groups, lean and obese (ten in each group) were participated in this study, and all subjects were detrained for 1-month. In both groups body weight, high, waist, hip, total calorie intake, serum testosterone concentration and insulin sensitivity were measured along with oral glucose tolerance test (OGTT). Results of this study: Insulin sensitivity was higher in lean subjects than obese before and after detraining. Although testosterone concentration was higher in lean group before detraining, this was not observed after detaining. Detraining significantly increased the obese degree, decreased the blood glucose homeostasis and testosterone concentration in the lean group. In addition, total calorie intake and triglycerides were higher in the obese group compared to lean group after detraining. Conclusion of this study: This data concludes that obese people have more chance to have physiological disorders than lean people after detraining. This result suggests that obese athletes required continuous regular exercise to attenuate obesity related problems.
