Abstract
本研究之目的為探討松杉靈芝之補充對大白鼠因力竭運動所導致的抗氧化狀態不平衡及其運動表現之影響。利用三十隻雄性Sprague-Dawley大白鼠,經一週適應期後,跑步機適應較佳的二十四隻,以隨機方式分為力竭運動(E)、力竭運動補充低劑量(0.1875 g/kg BW)(EL)、中劑量(0.9375 g/kg BW)(EM)及高劑量(1.875 g/kg BW)松杉靈芝(EH)等四組,其餘六隻則為控制組(C)。經三十天餵養後,控制組大白鼠立即犧牲,運動之四組大白鼠以跑步機經力竭運動後予以犧牲,採集其血液、肌肉及肝臟樣本。結果發現,能量代謝方面,與C組相較,E組之肌肉肝醣含量、血糖濃度顯著降低、血尿素氮濃度顯著增加(p < 0.05)。而與E組相較之下,EL組血中游離脂肪酸濃度顯著降低,EM組血糖濃度及肝醣含量顯著降低,而EH組肝醣含量顯著降低(p < 0.05),其餘數據皆無顯著差異。跑步時間方面,EL組、EH組較E組顯著增加(p < 0.05),且EH組又比EL組顯著增加(p < 0.05),而EM組只有增加之趨勢。抗氧化狀態方面,E組之紅血球SOD(superoxide dismutase)、CAT(catalase)、GRD(glutathione reductase)活性及GSH/GSSG比值與C組相較顯著降低(p < 0.05),而EL、EM及EH組其SOD、CAT、GPX(glutathione peroxidase)、GRD活性及GSH/GSSG與E組則無顯著差異,但EH組血漿TBARS濃度則顯著低於E組(p < 0.05)。組織損傷方面,E組血漿中AST(aspartate transaminase)、ALT(alanine transaminase)、CK(creatine kinase)及LDH(lactate dehydrogenase)活性顯著高於C組(p < 0.05),肌肉細胞凋亡情形也較嚴重。與E組相較,EL、EM及EH組其AST、ALT、CK及LDH活性皆無顯著差異,肌肉細胞凋亡情形則有較低的現象。以上結果顯示,大白鼠力竭運動前補充低劑量(0.1875 g /kg BW)松杉靈芝,可維持力竭運動後其血糖恆定及肌肉肝醣含量,並減少肌肉細胞凋亡的情形,而補充高劑量(1.875 g /kg BW)松杉靈芝,除上述作用外,更可增進脂肪利用及減少脂質過氧化物產生,以達延長運動時間之效果。
