Pediococcus
pentosaceus is a Lactic Acid Bacteria (LAB) commonly found in fermented
foods and used as a probiotic. P. pentosaceus can modulate oxidative stress
levels. Nevertheless, the impact of P. pentosaceus on physical performance has
not been exhaustively examined. Therefore, this study employed treadmill
training to simulate human exercise conditions and induce exercise-associated
fatigue in mice, aiming to investigate the potential of Pediococcus pentosaceus YF01 in mitigating such fatigue through the
regulation of oxidative stress, as well as its effects on exercise capacity and
gut microbiota in mice. Exercise performance was assessed using an exhaustive
running test, while histopathological examination of tissue sections,
quantification of serum biochemical markers, and evaluation of relevant gene
mRNA expression levels were conducted to elucidate underlying mechanisms.
Administration of YF01 significantly extended the time to
exhaustion in mice. It elevated serum levels of oxidative stress-related
markers, including total antioxidant capacity (T‑AOC), catalase (CAT), and
glutathione (GSH), along with glucose (GLU) and lactic acid (LA). Concurrently,
YF01 reduced serum levels of liver-related enzymes aspartate aminotransferase
(AST) and alanine aminotransferase (ALT), as well as exercise-induced
metabolites lactate dehydrogenase (LDH), blood urea nitrogen (BUN), uric acid
(UA), and creatinine (CRE). At the molecular level, YF01 upregulated the mRNA
expression of MyHc I, SIRT1, and PGC in muscle tissue, and increased the expression
of SOD1, SOD2, and CAT in both liver and muscle tissues. In contrast, it
downregulated the mRNA expression of MyHc IIa, MyHc IIb, and MyHc IIx in
muscle. Furthermore, YF01 supplementation increased the relative abundance of
beneficial bacterial genera such as Lactobacillus and Lachnospiraceae in the
gut microbiota of mice. In conclusion, P. pentosaceus YF01 appears to enhance
exercise capacity in mice by modulating oxidative stress pathways. These
findings provide novel insights for the development of strategies in sports
science and the promotion of human health.
