目的：探討八週不同強度跑步訓練對B型肝炎帶原者肝功能之影響。方法：受試者為30名自願參與本研究之男性B型肝炎帶原者，隨機分配於三組，包括：一、強度跑步訓練(HG組；22.5±3.58歲)：85% VO□，20分鐘；4 、低強度跑步訓練組（LG組；22.1±2.77歲）：50$%VO□，30分鐘；三、控制組（CG組；24.4±4.48歲），進行八週，每週三次的訓練。於訓練前(T□)、訓練四週(T□)、八週後(T□)及停止訓練後(T□)採血以分析肝能。研究所得之肝功能檢驗值以正常值作為判定標準。結果：三個不同運動訓練組，在T□、T□、T□及T□所測得的肝功能檢驗值皆落在正常範圍內。結論：B型肝炎帶原者經過八週，每週85% VO□以及50% VO□的跑步訓練，對肝功能並無不良影響。

Purpose: The purpose of this study was to compare the effects on liver function in hepatitis B carriers after 8 weeks of running training. Method: Thirty subjects were randomly assigned to three groups: 1. High intensity running group (HG, age=2.25±3.25yr): 85%VO□, 20 minutes; 2. Low intensity running group (LG, age =22.1 ±2.77 yr); 50%VO□, 30 minutes; 3. Control group (CG, age=24.4±4.48 yr). Blood samples were drawn from the subjects previous to their beginning of the training (T□) and after 4-week of training (T□), 8-week of raining (T□), 4-week of detraining (T□). Result: All liver examined values were in normal range at T□, T□, T□ and T□ in three different training groups. Conclusion: Hepatitis B carriers seem to tolerate 8 weeks of 85% VO□ and 50% VO□ running training well.
