The effect of orally supplemented coenzyme Q10 (CoQ10) on plasma CoQ10 concentration and aerobic capacity in endurance athletes was evaluated. Eighteen volunteer male road cyclists and triathletes, 8 in a CoQ10 supplementation group (QG) and 10 in a placebo group (PG), successfully completed the experimental protocol. Subjects were evaluated during and following graded cycling exercise tests, which were performed before and after 28 days of supplementation with 1 mg.kg-1.day-1 of CoQ10 or placebo. The presupplementation plasma CoQ10 concentration was significantly increased from 0.91 +/- 0.13 microgram.ml-1 to 1.97 +/- 0.27 microgram.ml-1 in QG following supplementation (p < .05). However, the CoQ10 supplementation regime had no consistently significant effect on oxygen uptake, anaerobic and respiratory compensation thresholds, blood lactate, glucose and triglyceride kinetics, heart rate, and blood pressure during and after graded cycling to exhaustion.
评估了口服补充辅酶Q10（CoQ10）对耐力运动员血浆CoQ10浓度和有氧能力的影响。18名男性自行车公路赛和铁人三项志愿者，其中8名在CoQ10补充组（QG），10名在安慰剂组（PG），成功完成了实验方案。在补充1mg·kg-1·天-1的CoQ10或安慰剂28天前后进行分级自行车运动测试期间及之后对受试者进行评估。补充后，QG组的补充前血浆CoQ10浓度从0.91±0.13微克·毫升-1显著增加至1.97±0.27微克·毫升-1（p<0.05）。然而，在分级自行车运动至疲劳期间及之后，CoQ10补充方案对摄氧量、无氧和呼吸补偿阈值、血乳酸、葡萄糖和甘油三酯动力学、心率及血压没有持续显著影响。
