密集運動訓練對B型肝炎帶原運動選手肝臟及血液相關指標變化之研究

The Effects of Consecutive Training on Hepatic and Blood Parameters in Hepatitis B Carrier Athletes

目的：探討連續五天密集運動訓練對健康B型肝炎帶原之選手肝臟及血液相關指標的影響。方法：本研究募集16位運動選手為研究對象，其中包括8位健康B型肝炎帶原之選手（H組）及8位健康之選手（C組）。兩組受試者在跑步機上，從事運動強度為75%V.O2max，時間為30分鐘，連續五天的跑步運動，並於第一天運動前（T1）、後（T2）與第五天的運動前（T3）、運動後（T4）及24小時後（T5）抽血。所得之資料以混合設計二因子變異數分析加以檢定。結果：一、肝指標：兩因子間並無交互作用，經主要效果檢定後發現，AST、γ-GTP、LDH及globulin等值於T5顯著高於T1（p<.05）。二、血液指標：在C組中，RBC與hemoglobin等值於T5顯著上升（p<.05）；而在H組中於T5卻是顯著下降（p<.05）。其餘各值經主要效果檢定後發現WBC及platelet等值於T5顯著高於T1（p<.05）；lymphocyte值則是T5顯著低於T1（p<.05）。結論：本研究發現經過五日密集訓練後，部分肝指標及血液指標有變差情形，運動員應在訓練時特別注意，並加強自身的健康維護。

Purpose: The purpose of this study was to investigate the effects of consecutive training on hepatic and blood parameters of athletes who are hepatitis B carrier. Method: Sixteen male athletes participated in this study. Eight hepatitis B carriers (HG) and eight normal healthy subjects (CG) were recruited. All subjects were asked to run on treadmill at 75%V.O2max, 30 minutes per day for five consecutive days. The blood samples were collected on day one at pre-exercise (T1) and post-exercise (T2), day five at pre-exercise (T3), post-exercise (T4) and 24 hr post-exercise (T5). All data were analyzed by mixed design two-way ANOVA. Results: 1) hepatic parameters: The values in AST, γ-GTP, LDH and globulin are higher at T5 than it at T1(p< .05). 2) blood parameters: In CG, the values in RBC and hemoglobin are lower at T5 than that at T1(p<.05), but higher at T5 than that at T1(p< .05). WBC and platelet values are higher at T5 than it at T1 (p< .05). Lymphocytes value is lower at T5 than that at T1 (p< .05). Conclusion: Consecutive training is harmful in some hepatic parameters. It also has negative effects in RBC and hemoglobin for hepatitis B carrier athletes.
