The objective of this study was to evaluate the influence of the ID-D01 (ID-D01) lactic acid bacteria probiotic on exercise performance and muscle fatigue in C57BL/6 mice. ID-D01 improved exercise endurance by extending treadmill running time and forced swimming duration. Moreover, mice treated with ID-D01 exhibited increased quadriceps muscle tissue weight, suggesting a potential for enhancing muscle growth. Serum analysis showed decreased muscle fatigue markers, and lower levels of lactate, and ammonia, indicating reduced exercise-induced fatigue. ID-D01 also affected intramuscular factors such as citrate synthase and glycogen. Notably, citrate synthase levels increased, indicating improved aerobic capacity, while intramuscular glycogen decreased. ID-D01 decreased reactive oxygen species and increased antioxidant enzymes SOD2 and catalase, in muscle tissue. This study identifies the potential of ID-D01 to improve exercise performance and relieve muscle fatigue. Further, it provides a rationale for the development of ID-D01-based functional supplements for individuals who are physically active.

罗伊氏柠檬酸杆菌 ID-D01 通过调节氧化能力提高 C57BL/6 小鼠的运动表现并减少肌肉疲劳

本研究的目的是评估 ID-D01 (ID-D01) 乳酸菌益生菌对 C57BL/6 小鼠运动表现和肌肉疲劳的影响。 ID-D01通过延长跑步机跑步时间和强迫游泳时间来提高运动耐力。此外，接受 ID-D01 治疗的小鼠表现出股四头肌肌肉组织重量增加，表明其具有增强肌肉生长的潜力。血清分析显示肌肉疲劳标记物减少，乳酸和氨水平降低，表明运动引起的疲劳减少。 ID-D01 还影响肌内因子，如柠檬酸合酶和糖原。值得注意的是，柠檬酸合酶水平增加，表明有氧能力提高，而肌内糖原减少。 ID-D01 减少肌肉组织中的活性氧并增加抗氧化酶 SOD2 和过氧化氢酶。这项研究确定了 ID-D01 提高运动表现和缓解肌肉疲劳的潜力。此外，它还为针对身体活跃的个人开发基于 ID-D01 的功能补充剂提供了理论依据。
